    Techart adapter and Contax G question

    I just got the Techart III adapter in the mail today. I also just purchased the 45 f/2 and 90 f/2 lenses. The 90 mounts and tries to AF. I can manual focus it. The 45 mounts, but will not AF and when I turn the manual focus wheel, it spins loosely. It is not engaged. There is no AF.
    I have put it on several times. I've had Contax G lenses before on a Contax II and on a NEX with an adapter (which I unfortunately no longer have), so I know how to mount and unmount a Contax G lens properly.
    I am not sure if I am missing something in the gibberish Chinese translation instructions. I have my lens AF on the shutter button. The rest, I'm not clear on. I don't know if the problem is with the 45mm lens or with the adapter or with me. I'm pretty sure that the adapter needs a software update because it is hunting a lot, but I don't want to go there till I figure out if I should send it back or not.
    I have tried it on A7rII and A7II.
    Any help would really be appreciated.

    Re: Techart adapter and Contax G question

    I have the same lenses and issues. The adapters are finicky and require a bit of trial and error. I have had more success mounting the lens to the adapter before mounting to the camera but you might have a different experience.

    If if the the dial spins loosely, then it isn't engaged correctly so try holding the lens by the middle ring and push it into the adapter firmly and then twisting to the right to lock it in.

    Hope this helps.

    Thanks for those suggestions, Derek. I had previously tried locking and unlocking, and different sequences of mounting, and I can't get that wheel to engage.

    Re: Techart adapter and Contax G question

    I have a love/hate relationship with the version II of this adapter. It doesn't recognise my 45mm either. I have the opposite problem though where it refuses to move the lens for focusing but I have no problem on a manual adapter and on a contax g camera with the 45mm so I know it's not the lens. My 90mm wouldn't AF when I first received the adapter and this is what they told me to do.

    turn the camera aperture to f/25, and full press the shutter, capture the image,

    - turn off the camera and return to f/2.8

    - AF should work again.

    I can confirm that Deotek smart adapters are finicky. I have two different versions : one v2 and one v3 and each works better with different lenses.

    The adapter uses exotic Fstops to achieve some tasks. When you put it at F25, you can change from MF to AF. The process is as described above, to change from MF to AF or vice versa.


    Frankly, those adapters cost a lot, but never worked very efficiently on my A7r. This prevents me from using those nice and light lenses on the A7r. Now I prefer the Sony 55mm F1.4 to the 45mm, or the Tamron 90mm F2.8 plus EOS Smart adapter, to the 90mm F2.8. I should just get a dumb Kipon manual one.

    Re: Techart adapter and Contax G question

    I am retiring all my CG glass back to their Contx G2 kit bag it appears. I recently got a FE 55 and imp it is better than the cg45 which I never would of predicted. I have to assume the FE 90 macro will end up as better than the last CG lens I am currently carrying in my a7rII kit. I fully expect to the CG90 back to the Contax G2 bag on my next lens purchase.

    I have been a huge fan of the 45 and 90 but their performance has finally been exceeded. But with the 90 their will be a size penalty to beat it.

    That goes for all Sony FE mount lenses. The attraction behind the old G lenses is the size.

    Re: Techart adapter and Contax G question

    Thanks for all of the help. I still have not been able to engage the manual focus on the 45. It is very hard to get it to even mount. I really wanted this to work. I have the Sony 55 f/1.8 (and 50 R, M, Dark Night, Zooms at 50). I wanted this to work because I love the way these Zeiss lenses render.

    Re: Techart adapter and Contax G question

    Cindy,
    At least for the A7RII, I think the adapter needs an update,
    http://briansmith.com/techart-ga-3-f...a7rii-support/

    I am so on the fence about moving to FE 55. The size of the Contax Gs is so great. I am also still shooting slide film since it projects better than digital, and want to use the same lenses on both cameras.

    The FE 55 is a great lens, no doubt. BUT, I find it incredibly sterile.

    The focusing mechanism of the Contax G lenses are activated by a screw which you can see on the mount. Try turning that screw, in order to check whether it is blocked or hard to turn. If it is hard, you may give it some more turns to smooth things out. Also, look at the adapter put in front of the lens mount and examine how the two parts are going to plug in : that screw and the mini screwdriver on the adapter are vital parts and sometimes don't match very well.

    Or may be it is just that you need to update the adapter. That was necessary for the EOS-> FE smart adapter on the A7r2 too.

    Withe the 45 mounted set the camera aperture to f/2 and leave it there. Set lens aperture to whatever you need. With the 90 set camera to 2.8. They both work fine for me with vIII adapter and firmware version 2.0. My adapter did not come with 2.0 installed so I had to use the iPhone app to update.

    Good luck,

    Thank you, Annna T. I found that the screw is binding badly on the 45mm. I turned it back and forth several times, but it still binds in the middle. I can see why the auto focus does not work with it (manual focus does not work either). I am going to send it back.

    Thanks for the information, Carl. The 90 is working, so I have narrowed down the problem to the screw drive on the 45mm.

    Thanks to everyone for your input. I understand how it all works now and think that I can enjoy this adapter and the Contax G lenses once I have the lens problem sorted out.

    I agree about the sterility of the 55 (and Batis 25, by the way), but I think the 45 G is almost as bad - superb for B&W though.

    The 90 G, on the other hand, is really nice all around - an ideal balance of qualities: not quite as sharp as the 45 but not at all lacking, has a somewhat delicate presentation (great for landscapes), excellent color rendering, very useable at 2,8, small and lightweight.

    I just wish I could find a light weight manual adapter with smooth focusing for it.

    The TechArt adapter offers very smooth manual focusing in addition to AF. The MF works well with peaking and magnification provided by the A7Rx. The 35 G (at least my copy) also has some very nice rendering and not as contrasty as the 45.

    I don't understand this reproach of sterility concerning a lens like the 55mm F1.4 : it is tack sharp, exhibits a lot of microcontrast and a nice soft bokey. The most frequent reproach against the Contax G lenses at the time was that they had a busy bokey, compared to Leica glass. But that is solved with the 55mm F1.4.

    Or may be that is because these reproaches come from persons who are adverse to the "German Sachlichkeit" ?

    I am not dissing the 55 f/1.8. I have had it for almost 2 years and use it a lot. It is just a bit too perfect for me, and for me, that translates to sterile. I guess I like something a little quirkier.

    Re: Techart adapter and Contax G question

    I love the manual focus from the 90 f/2.8 and this Techart adapter. Manual focus is much better than the previous G to NEX adapter that I used to have. I could not get the 45mm to AF or MF. It has been sent back, and I've ordered a replacement. I have the 35G and love mine, but it has the Leica M mount, so I won't be able to AF with it.

    When we get better cameras from Sony without lossy compressions and shutter shock, it will get interesting.

    On sony cams, the higher contrast (55 and others) is useful when a lens is stopped down to minimise diffraction effects.

    "Too perfect", "Sterile"- it (Zony FE 55/1.8) is not. It shows CA until f/5.6 (it is still there but much less), distortion, etc. It has its own "character".

    I was wowed by the 55 when I first received it but now I feel the same, that it's very clinical.

    Re: Techart adapter and Contax G question

    There is another firmware update (version 2.1.0) now available for the Contax G to Sony E adapter. I haven't had time to evaluate, but seems to be about the same as v 2.0.0 in terms of PD AF performance, maybe slightly more reliable when stopped down and/or shooting near min focus distance.

    Re: Techart adapter and Contax G question

    I finally have resolved my Techart adapter problems. Thanks to Annna T, I was able to figure out that the 45mm Planar lens that I had purchased had a problem with the screw drive. I sent it back for a replacement. I was still left with the problem that once I took a shot, manual focus was disabled. I could still AF, but I had to turn the camera on/off in order to restore the ability to manual focus. I contacted the manufacturer. He said that the latest update addresses that problem. I had already updated. He asked me to try updating again. Now my problem is solved. For some reason, the previous update did not "take", even though the app showed that I had aa successful update.

    Thanks to all who offered help. It would really be helpful if the instructions were more user-friendly. I'm so glad that I have this forum to turn to.

    Re: Techart adapter and Contax G question

    for those who doesnt want to spend as much, or want a 50mm instead of 55mm and does not mind manual focus. it's worth taking a look at Ricoh 50mm F2 (K mount). after a series of tests, i concluded that i cant tell the FE55mm from the 50mm F2 when wide open. when stopped down, the zeiss colour does give FE55 an edge, but only just. (my friend has the Ricoh and i have the FE55. i tested both on A7r mk1 not mk2)

    Is your sample of 55 that bad?

    Re: Techart adapter and Contax G question

    So there have been a couple of new FW updates for the current adapter and I know it improves things a lot for the A7RII. Given though, that I own and love an A7II, does anyone have experience with the adapter on this camera? I really want to pick one up but I don't want to waste my time & money if it's too finicky for prime time. Thanks!

    I finally got an A7rII, so it is time for me to update this adapter. Since I have never updated it, I am wondering : do I need to make all the intermediary updates ? Or can I jump directly to the last one ? There are five updates listed for the TGA3.

    I don't even know which firmware version is mine. Is there any way to know it ?

    Thanks in advance for any info.

    Thanks in advance for any info.
    I don't know about finding your firmware version, but when I was having a problem with mine, the manufacturer sent me this message:


    from: kpliang@163.com


    Hi,
    you can try to update firmware once again,it will be ok,we upgrade file at 2015.10.07 to resolve this problem.
    Thank you

    You might use this email address to send a message and check with them. I would just go ahead and try the most recent update first.

    I think also that the most recent (2.1) update should be fine. Chad has listed the steps you need to follow for doing the update in a comments reply on his blog. Working very nicely in phase detect mode on my A7RII with the 35 and 45.

    Re: Techart adapter and Contax G question

    Just curious.... how is this new updated Techart CG to E AF mount working with the CG90 on the a7rII?

    The CG90mm is the only one of my CG glass I have note replaced with OEM glass in my FE kit and honestly am thinking about the 90mm macro to replace it. I don't like to do macro's with full frames and will continue to do them apc's so the reason for a 90mm on this FE system for me is a bit more reach and the one or two portraits I may "have to do" every year (since my days way back in film doing events and such I have a serious aversion to "people" shots and go out of my way to avoid them in my images... but you know how family pressures can be when momma want's a pic of her darling grandchildren )

    The CG 90 is such a lightweight sweet piece of glass that if it could auto focus well I just might be able to save some serious cash and be happy as I might of been with the OEM 90mm macro. Those that are using the CG90 and Techart III updated version on a7rII's what do you say? Does it AF fairly well and fast? Or should I just bite the bullet and spend the grand on the 90mm macro for my stated needs..... I am looking for AF options as I am a old coot and though manual focus is great on the Sony mirrorless bodies I sometimes wish I could just leave the focusing to the camera when time maybe a issue. $300 for a adapter beats near $1100 for a lens especially as with this body I see the system as more of a hike in scenic tool than a tool to use long glass on for things like BIF (the a77II handles long glass and fast AF extremely well for me and see no reason to change at this time)

    General question (OT):

    Why don't techart (or anyone) make an M adapter with a build in helicoid?

    ??? There are plenty of these. From the Voigtlander VM-E to the Hawks and many other choices on ebay. If by M you mean M mount to Sony E anyways.

    Excuse me for that incomplete post.

    I meant an adapter with built in helicoid and a servo motor so that it will do AF.

    (Basically what happens with the techart adapter and the G lenses )

    I see B&H is listing this Deo Tech 3 adapter as a new product coming soon.... Wonder if it will come with the latest firmware... I am not very computer techno savy and if they have unclear instructions I might have issues to overcome.


    What's with the setting the camera at one aperture and the lense at another? I watched a video with the golden eagle and a cg45 on a a7r2

    Vivek that would be idea for using older A mount Minolta AF glass without a translucent mirror .. Interesting that no one does. Maybe Sony will?

    Jim, You just need to set the camera to f/2.8 and then set the lens to the desired aperture. The documentation is not good. Read what Chad Wadsworth has written in his blog (see Carl's comments for link). I would be glad to help you if you PM'd me when you get it. Everyone here helped me get going when I got mine.

    I am very happy with mine. The only thing that is oft-putting for me is that it is loud when it runs the screw drive, but I can live with it to have these nice lenses on A7II and A7rII.

    Thanks Cindy..... did you order from a USA dealer or through their Ebay sales? I like the idea of a USA dealer to deal with but B&H have no idea when these will arrive in their store.

    Cindy B&H expects them 11/30/15.... but the fiasco I had with expected dates and the A mount version of the Tammy 150-600 that ended up 10 months later than their expected date I do not have much faith in expected dates.......


    How long does it take to get one from MX camera in Hong Kong and how much BS did you have to go through ordering it direct.... seeing Chinese on a website and prices in their currency kinda makes the warning hairs on my neck stand up

    Vivek it just makes sense ...... why not if they can do it with a Contax G screw drive? If I was running Deo Tech I would demand my engineers make it...... get in before Sony does.

    Hey guys, I can't believe I've missed all this great discussion on my favorite adapter/lens combo!

    Hope everyone is sorted but if there are any outstanding questions I can help with let me know.

    As far as the comment above - I made the suggestion the minute the a7RII was released. Who knows what Sony is and is not able to accommodate but believe me, this would be a dream. I want to use my 135/1.8 with the native a7RII AF system soooooo badly.

    Re: Techart adapter and Contax G question

    SP, two quick questions

    Will any new Golden Eagles ordered from Either B&H or MX have the newest firmware installed (B&H is stating 11/30/15 as expected ship date)


    Also if I order from MX in China how long will it take to arrive to the east coast of the USA and how big of a hassle is it doing business with them....I don't have a warm and fuzzy feeling buying from the Far East. I usually reject anything on the auction sites I see offered from over there or the Middle East.

    Re: Techart adapter and Contax G question

    Jim,
    I ordered mine from eBay. It took a couple of weeks to get here. It did need to be updated, but that only takes a couple of minutes. Chad's blog has a good description of how to do it.

    I just tried the MXCamera site to order it and the order would not take..... the site just froze (guess the translator/currency converter was absent )


    Think I will wait on B&H ....... I have a Kipon on it now.

    Many tanks to Carl and Cindy for their input. Alas this time I'm the one stuck. I had installed the A7rII last firmware version before trying the updating of the adapter. May be that was my error ? Then before i read the post of Carl I had found the link to Chad's blog on Bryan Smith website. Alas I just read the article, not the comments. So I missed the part where you have to shut the camera down (since you operate that way with Canon lenses in some circonstances and since I thought the adapter would need energy run the update, I let the body on). Second error. The adapter can't be detected when the body is on. I tried with the tablet, then with the iPhone, no way. then I tried downloading an earlier version. No way. That's when I begun to read the comments and found the detailed steps.

    Ok I was able to connect the adapter to the tablet and downloaded the software. It was written successfully and verified successfully. Then another title line said : install firmware.. but nothing else happened : I waited for 15 minutes and still nothing. So in the end I shut everything down.

    When I plugged the 45mm on, at first it was working. I made one or two tries and it was great. Really. Then I put on the 90mm and it didn't work : it didn't even connect to the adapter : I had a black display, or I could get an image, but the F. Was red and without value. Turning the aperture wheel wasn't working either. Then after a while nothing worked at all : I put the 45mm on and got the same black display. Same with the 28mm. Yet fitting the lenses on the A7r with the TGA 1B (the previous adapter you can't update yourself) : all three lenses were working. So I know for sure that the problem doesn't lie with the lenses, but with the adapter.
    In Chad's comments section I read that someone else was having trouble with the updating and the process remaining stuck exactly like with mine and he also had the last firmware installed on the A7rII.

    So it may be better not to try the update if your A7rII already has the last firmware installed. Or I made something wrong along the way : like the display going into sleep, or what else.. Anyway, I'm stuck and very frustrated since I have seen how well it can work when it work !

    Try removing the camera battery, wait a few secs, replace battery and try again. I had some problems with my 90 struggling to focus and reverting to contrast detect focus, but resetting with the battery removal fixed it. My 35 and 45 work very well in phase detect mode.

    Re: Techart adapter and Contax G question

    Anna none of that sounds like fun but I hope someone knows exactly how to correct this for you.

    As a old coot and computer savy challenged it is things like you are experiencing I avoid like the plague. When I read things like the instructions are vague or difficult to decipher, when I go to a blog and try to view a video on how to update software and see the prompt the video doesn't exist, when a site doesn't function and has lots of foreign language on it, when you read user issues with various aspects of using or uploading firmware, Etc.... My "stay away from this product" warning senses are activated. Hopefully if and when B&H gets this product in someone there will know the ins and outs of the product, will speak English as a first language, and will be available for us computer challenged old coots if we hit a issue. As I stated before I resist buying on the auction sites if the seller is outside the USA and it is for reasons such as this. I am very happy to manual focus my Kipon till B&H gets product on the 30th of next month or when ever.

    Anna as initially stated I truly hope your issue is easily resolved and you can get back to being a photographer with it rather than a frustrated software tech and translator. Products should work as described without the owner having to learn other languages and professions to use them.

    Re: Techart adapter and Contax G question

    I would follow Chad's directions to the T and start over and do it again. I had to do it a second time (per email from manufacturer). One caveat that I found was that I needed to turn off the sleep mode on my phone (iPad would be the same). The first time, I believe that my phone went into the sleep/lock position and the download stopped. Make sure that you get a message at the end that the process is complete.

    If it won't let you update at all, then use the email that I posted before. That is the manufacturer. Tell him what you told us.

    Re: Techart adapter and Contax G question

    I thought maybe it would be helpful to list the steps here. Thanks to Chad Wadsworth who set me in the right direction when I got mine.
    If you see something that is in error or want to add more, please do so.

    1. You need to download the Techart app from the App store and turn bluetooth ON in your device and auto-lock OFF. You don't want your phone or pad to go to sleep while the update is happening, or it will stop the update. Click on the correct TA-GA3 update (the one with the highest Version number). A check mark will appear next to it.

    2. Mount your adapter on the A7RII and mount a Contax G lens.

    3. Turn the camera ON. Set the aperture in the camera to f/90. Take a shot. Turn the camera OFF. REMOVE the lens only. Lay the camera with the adapter on it, right next to your phone or pad. Leave the camera OFF.

    4. Press UPDATE on the App. You will wait till the device is found. Once you see that the device is found, don't touch anything until the message is given that the update was successful. (The update took a while, so be patient.)

    5. Mount the lens. Turn the camera ON. Set the aperture on the camera to f/2.
