    Fixing My Expensive Adapter

    Just to let folks know that an expensive adapter does not always warranty you a perfect result. On the Voigtlander adapter, there is a light rubber gasket which protrudes into the light path too much and causing corner vignettings when shoot wide open. I removed the inner ring and repainted the inside of the adapter where the rubber ring was residing with matte paint to eliminate the problem. Thus, do not give up on your adapter whether it is expensive or cheap too quickly. There might be a solution to the problem you are experiencing.

    Best Regards,

    Re: Fixing My Expensive Adapter

    I like to dedicate this thread to the current adapters with problems and providing solution to to fix them. I would hate to see folks trashing or selling their adapter cheap assuming there is no fix to their problem. Furthermore, buying another expensive adapter after getting rid of their current one may not solve the problem and ending up with spending more on the same issue. When I get the time I will post images of the before and after fix to the adapter and the improvement to the image as well. I encourage other who found a way to fix their current bad adapter to post their solution here as well to help the community.

    Re: Fixing My Expensive Adapter

    I have two voigtlander adapters. I have a problem with both on my Leica 135mm 3.4. I posted an image in another thread. I get dark corners but not sure i would call it vignetting. It does not change with aperture. The other problem i just am noticing is that the voigtlander is giving me very poor edges on the LECIA MATE 28-35-50. In fact I thought it was just the fact that lens did not work well on the A7r. However I am getting much better images using a metabones. In contrast, the Leica WATE and 90mm 2.8 M work well with the voigtlander. One of my voigtlander adapters is the close up adapter and I like what it can do. I am not sure if there are any other close up adapters out there.

    Re: Fixing My Expensive Adapter

    The Hawk close up adapter does present corner issues on most lens. However if you own this lens and have the older Leica Elmarit-M 90mm, you can use it without a problem. Also if you focus close up, the corner issue can be attenuated significantly. At infinity focus, the vignetting is a huge challenge to the lens itself and adding on top of that, the contributing corner blocking from the adapter. Thus, if you have macro and slow lens they will likely work better on these corner blocking adapters. If you like to dedicate each lens to its own adapter and rear cap, you can lessen the problem and be able to use the adapter.

    Re: Fixing My Expensive Adapter

    WEll both my voigt adapters.. the regular M to E and the close up (at the infinity--nonclose up setting) present the same issues. The 135mm has the same dark corner issue in close up mode but I have not done enough with the close up setting with any of the of the other lenses with the exception of a couple of quite shots to form a solid opinion. For the few shots i took with my other lens i was generally impressed with what the close up setting can do. HOpe to do more this weekend.

    Re: Fixing My Expensive Adapter

    Hi Son, were you referring the the new Hawk that came out recently for FF or one of the original versions released before the A7s? I have the new one, which also has an infinity lock, but no A7 to test it with yet (just using it on Nex).

    Re: Fixing My Expensive Adapter

    I bought an inexpensive adapter to try my Contax G lenses on the A7 before putting out the money for the Deo Tech auto focus adapter. It is a Kiwi Fotos, basically a Kipon copy. It actually seems well made and focusing works well with the 28mm and 35mm lenses, some glitches with the 45mm and essentially not at all with the 90mm. The major problem though is that it won't focus to infinity as it is too thick (over 12mm when it should be 11mm). Postage is too expensive to mail back, has anyone found a cheaper way to send items back to Hong Kong from the US or tried to fix an adapter that is too thick?

    Re: Fixing My Expensive Adapter

    I have to say I feel for you guys as I got a secondhand seemingly unnamed (probabaly a KIWI) adaptor for 10 that works perfectly with all lenses. I suppose it is just a matter of luck

    Hi Michael,
    It is the older one.

    Hi Son, yes the older one will not cover. Like Metabones Hawk designed a new one for FF E mount. As I said I don't know how it performs yet (eg does it have some of the flare problems reported from some lenses using the FF Metabones EF-E adapter)

    Re: Fixing My Expensive Adapter

    I also have the latest Metabones Canon EF-Sony E smart adapter III and I tried it with the only Canon EF lens, 17mm TS-E, and it seems soft in the corners. I have seen reports of fixing the flare but not smearing on FM. I will build adapter again to see if I can fix recent issues.

    Fred (on FM) made a recent post saying that he seems to see field curvature easier on the A7r and thinks it's due to the extra resolution. This is of interest to me as I have the 17tse and it will get a lot of use when I buy the A7 or R

    Tim (Tashley) brought this up in the Fun With A7/A7R thread, as he described focusing "deep" into the curvature, and threw in some "umbrella science" and such.

    Re: Fixing My Expensive Adapter

    Well I had my brand new, literally out of the box brand new and never used Olympus OM 21mm f3.5 MC lens delivered a couple of days ago. I had bought a very expensive Novoflex adaptor to go with it. I hadn't yet taken a single frame when the lens with adaptor attached rolls off the table and hits the stone floor. There is a tiny dent in the adaptor where it meets the camera. I thought it was indented and therefore wouldn't be a problem to the fit but I did some testing with the camera and lens today and indeed the right side is slightly out. There is a slight, 1/10 of a mm protrusion at the edge of the tiny dent. I doubt it would be noticeable with a 50mm lens and could be filed back down easily by someone more talented than myself with the right tools however I just went online and spent another 99 on a new one. Sigh...

    BTW if anyone wants a DIY project, I'll sell the old one for 50, half price. It really is a tiny dent, doubt I could even show it in a photo.

    Ben, I'm sorry for your loss. It always sucks to drop gear, but brand new especially so. Hopefully the lens elements are still in proper alignment for you.

    Re: Fixing My Expensive Adapter

    It's costing me 99 or a new adaptor just to be able to test that which sucks even worse! I wouldn't know where to send the lens for alignment if it is problematic, who services manual lenses out of production for over a decade with that level of perfection? I know there are people who do Leica lenses but...

    Heck let's hope it's the adaptor. Makes the most sense as that is where it hit the floor and there is a visible dent.

    Can you take a picture of the bent adapter so we can give you suggestion to fix it and be able to sell it to compensate your lost?

    Re: Fixing My Expensive Adapter

    Son - I was suspicious of my Voigtlander adapter too. So I tried to remove the little plastic collar, but it looks like you have to take the actual adapter apart or cut the collar in two. I started to take the adapter apart but the screws are very soft and tight so I started stripping the heads and gave up.

    How did you remove it?

    Thanks,
    Gary

    Re: Fixing My Expensive Adapter

    Sorry for the delay. Haven't had time to set up studio stuff for a while. Had to take some product shots and took the opportunity. Here goes.



    The dent is quite noticeable at the top right (front) end of the adaptor. This is the camera side of the adaptor. What is less noticeable is that the dent protrudes upwards a tiny fraction at the back, at the top of the 'slope' of the dent. Bit more apparent in this next image.


    My new adaptor arrives on Sunday but I don't want to throw this one in the garbage just yet, especially as it cost me $160 and I never got a single non problem shot out of it! Thank you Son and everyone else.

    Re: Fixing My Expensive Adapter

    Speaking of adaptors, I have a single Cameraquest C/Y to Canon adaptor currently living on a Zeiss 21. I would like to move it to a Zeiss 28 to check this lens, but I can't figure out how to remove it! I've poked at likely spots, but I'm about to damage the thing if I push any harder. Does anyone have advice (or a picture) of where and in what direction to push?

    Thanks,

    Matt

    Re: Fixing My Expensive Adapter

    I got the new olympus adaptor and now both sides of the lens are the same, no more problems. I'm not going to keep it though. It's good but I need a lens for commercial work and the corners are good but not perfect. I think I may have to *gulp* buy the Zeiss. Have to sell off a bunch of stuff to be able to afford it. I could get the Nikon 14-24mm which is as good but it's a big beast! It's either that or wait for the Sony Zeiss 16-35mm f4 E mount and hope it's good.

    It depends on the adapter so I suggest you post a pic of it looking directly onto the back of the lens. Many of them have a thin spring that holds the adapter in place by engaging into a notch on the lens mount. You need to use your nail or a screwdriver to hold it open as you start to rotate.

    If this isn't obvious post a pic.

    Just saw this. Ugh, painful. But at least it wasn't the lens that was damaged.

    These mount adapters are made of light metal and are very precisely machined. Dropping them, even if the dent looks small, can deform them and it's *very* difficult to restore them to the proper shape. The same thing happened to me with a very expensive B+W type 87C infrared filter. It dropped only a foot or so onto a hard surface, deformed the mount, and now I can neither take the filter element out or fit it to a lens. So goes another $100+ ...

    I'll be interested to hear how that lens works out for you. I'm debating something like that or the Elmarit-R 19mm ... expensive things ...

    I'm guessing that it's the (now slightly mangled) bit at 3 o'clock. I was unable to budge it in any direction with finger nail or screwdriver. I hope I've been pressing on the wrong spot! It's not that teensy hex screw, is it?

    Re: Fixing My Expensive Adapter

    No, this one doesn't have the spring. If I remember correctly this type does use a very small set screw. I have one on a lens but not sure it's with me, in which case it's at home and I won't be able to check it until Friday evening. It may well be that screw. The spring, if it had one, would have engaged in that "shark fin" just above the screw

    Re: Fixing My Expensive Adapter

    Mike,

    It WAS the small set screw. After removing it, the adaptor came off easily.

    Now for the really embarrassing part. When I tried to place it on my C/Y 28/2.8, it wouldn't fit. Because there was ALREADY a C/Y to EOS adaptor on that lens. Senility isn't pretty...

    Now I can compare that lens on my trusty 1DsII vs the Pana 12-35 on the EM-5 and Leica 28/2 on the M9. I already know the answer, though. At any size I'd print, it won't matter. When has that stopped us?

    Thanks again,

    Matt

    I'm not keeping the lens in the end. It's good but I realise that I'm looking for perfect corners and it's not quite there. I need the lens for commercial work not artistic. Thinking of either the Zeiss, the nikon 14-24 or waiting for the sony wide angle for E mount and hoping it's good. It's a shame it cost me two adaptors to find this out but the other one is pretty much brand new, only mounted once. I'm hoping not to lose too much money selling the lens and adaptor.
