    Re: A7rII with Canon AF database reference.

    just saw a short video in which someone tested their Canon 70-200 F2.8 - worked fine. However, he stated that any Canon AF lens manufactured from 2006 to the present will AF fine on the new Sony A7Rii - using the Metabones IV adapter.

    Pre-2006 AF lenses will not AF...

    No third party lenses (for example the new Tamron 24-70 F2.9 released 2013 or so) will AF on the new Sony camera.

    Re: A7rII with Canon AF database reference.

    Yea I'm worried about my Sigma 24-70 A mount with the LAE3 will know today if it works or not. I'll post that on the Sony A mount thread

    Re: A7rII with Canon AF database reference.

    Works :

    35L

    50L

    85L II

    24-105L

    70-300 DO

    Doesn't work :

    135L 2.0

    200L 2.8

    My subjective view is that - with one exception - those that worked at all performed better on the A7R2 with Metabones 4 than they did on my 5D2

    I was quite surprised that the DO lens focuses but performance is rather erratic. Sometimes fast and sometimes annoyingly slow. I have not yet worked out a reason for this.

    It is a shame about the 135L and 200L -b oth of which I like a lot. They just hunt for focus, never achieving it. However, both of mine are 6-8 years old and perhaps more recent copies will fare better.

    In the meantime I have my Leica 135 f2.8 and 180 f5 R which give really good results on the A7R2. Though they are both manual lenses, focus is quick and easy. They can be found quite cheaply second hand and are both brilliant lenses.

    The 5D2, 200L and 135L are now awaiting disposal on eBay! I'm not sure whether I will keep the DO.

    Re: A7rII with Canon AF database reference.

    Have those using the Metabones IV adapter updated the firmware to the latest version?

    It is V.42, when I updated my adapter my 300 F4 L would work to change aperture. Before the update it did not change aperture or focus. It also would auto focus but slowly. Will test with A7RII when it arrives.

    Link to page on Metabones site. Firmware Window or Mac option on right.

    I just tested a Canon 20mm F2.8L II, and a 50mm F1.4. Both change aperture and focus (slowly) with both the Metabones IV and Fotodiox adapters on an A7II. Based on what has been reported with pre-release sample A7RIIs those lenses should work with much improved AF on the A7RII. Adorama confirmed mine is in the que for shipping. Should get here Friday or Monday.

    Re: A7rII with Canon AF database reference.

    Anyone have a 400L f5.6 to test? That's sort of my dream, being able to at least single shot AF with this thing on the A7RII, with IBIS It's a pre-2006 design, but fingers crossed.

    Re: A7rII with Canon AF database reference.

    Canon lenses with Metabones IV latest June 2015 V0.41 firmware:

    Work:

    24-105/4L
    24-70/2.8L II
    85/1.2L II
    16-35/4L
    70-200/2.8L II

    Do not work
    (engages AF but hunts and never finds focus):

    50mm/1.8 II
    50mm/2.5 macro
    100mm/2.8 macro USM (previous version, not new L version)
    135/2L
    Conurus converted Zeiss Contax N lenses (24-85, 85, 100 macro)

    Sigma Art:

    Turn off APS-C/Super35mm in #6 of the second menu set, otherwise file size will be AUTOMATICALLY limited to 18MP!
    35mm ART and 50mm ART both work.

    I am really sad about the 135mm/2L not working.

    Re: A7rII with Canon AF database reference.

    Well I maybe should have held my words about accepting something that is just different and adapting.

    Works so far:
    35L
    24-70II ok

    Doesn't
    100L new very, not very well
    100-400 II horrible and I use this lens a lot


    More to come but so far, I may eat my words of positive input. I find that the camera is hunting like crazy and the target has to be choice for it to lock on.

    Re: A7rII with Canon AF database reference.

    Thanks all. For those with the 24-70 2.8 II, how does AF compare, in speed and accuracy, to using it on a native mount Canon body?

    Incredibly useful zoom range, of course, and with Sony's 24-70 falling well short of world class--good AF performance would make the Canon a killer option for the A7RII.

    Yea this going to be be painful for some Canon shooters. Im feeling the pain on a Mid zoom and a 135/200 option too. Honestly though the reason is as well I want every last AF point i can get my hands on. If I did did have that desire i would be just fine and I am. I am so thrilled at what I have today the VC 15, Batis 25, 35 1.4 and Batis 85. There is not a dog in there.


    You know from what I have read the Sony 70-300 is supposed to be really good.

    Im personally trying to stay Sony but I can go Canon if you twist my arm really hard

    Metabones IV, with the .41 FW. Not doing well on the 11-24L either. Not good on the 100-400II and not living up to what Sony put out there as a camera that would work with many different lenses since they have even packaged the adapter for EOS lenses in Austria in the past.

    I'm curious about the 100-400mm Version II. I used the Version I with the Metabones III and a7R successfully. Some AF hunting, but IS and the other functions worked. Does the AF hunt so horribly that it's rendered useless?

    Actually, Guy, it's convincing me to just grab a reduced price 1DX for the Canon glass and keep the MF stuff on the Sony. Imagine, a camera that AFs with ALL Canon glass! And what AF!

    Glad you're having a blast with the new camera

    It works fair with the range up to around 300 but hunts some then at 400 forget it. If I am going to use a lens, I want to use all of it. So far not a happy camper as the videos led me to believe this was going to perform far different. Last time I put my faith in web videos like that.

    Right now it is making a nice body for my Leica lenses but that isn't why I bought it. I have the M9 for that.

    Re: A7rII with Canon AF database reference.

    This is a very valuable thread...... too bad that I just happen to own the Canon lenses that don't auto focus. I'm also assuming that this adapter (Metabones lll) is the only one that will set the aperture.... correct?

    No, it's not the only one. Brian Smith has a good summary on his blog here.

    Thanks Joe according to Brian's list the 135 and 200 version II work with the Viltrox adapter. This might be worth a try for someone that has those lenses.

    I actually thought about buying the 200 and adpter myself and try it. Than reality hit me. Lol

    Re: A7rII with Canon AF database reference.

    spence-- Unfortunately the 400 5.6L does not work. I can get it to lock on every once in a while, but thus far the 400 5.6 and the 100 2.8L macro are the only Canon lenses that do not work for me. Take what I say with a grain of salt because the a7rii just arrived a couple of hours ago and I've only been using it for about a half hour thus far.

    Regarding the relative speed of the 24-70 2.8 ii, I think that brings up a good point; we are talking in a binary fashion that a lens just works or it doesn't, but there are of course degrees of how well it works. I have just cursory impressions but would say it is not as fast as using the 24-70 ii on the 5dmiii, but it's still quite good and quite usable for most purposes. Every once in a while, I get a very slight extra judder at the end for fine focusing. Maybe others can chime in who have used this lens with the a7rii for longer than the few minutes I've had it.

    I'm going to try to shoot sports in the next few days-- probably kiteboarding or windsurfing (I'm in San Francisco)-- with the 70-200 2.8ii both with and without the 1.4 tc. This lens definitely "works" but does it work well enough for sports or other fast moving subjects? Obviously I didn't get the a7rii for sports, but I'm trying to move from Canon to Sony and I'm hoping I can shoot 80+% with Sony now (also have the a7s). Really the only reason I'd shoot Canon now are: long lens/sports (which I don't shoot often) and using speedlites (and this could just be what I'm used to).

    btw, I'm really disappointed to hear about the 100-400 ii. I was thinking about getting this lens very soon. What are people doing for long lens choices?. Should I consider the 70-400 Sony with a sony adapter instead? (I know nothing about the sony adapters and A mount lenses).

    Much of this is a repeat, but:
    Works:
    16-35L 2.8 ii
    35mm 1.4
    85mm 1.2L (slow on both Canon and Sony! but lovely)
    24-70L 2.8 ii
    24-105L f4
    70-200L 2.8 ii

    Doesn't work:
    400L 5.6
    100L 2.8 Macro
    Zeiss 21mm ZE (kidding. . . )

    Thank you ebbtide. The Canon 24-70 II sounds like it might be a winner. Keep us posted as you continue to shoot

    Disappointing to hear the 400f5.6 is a no-go. Which adapter and firmware are you using?

    Re: A7rII with Canon AF database reference.

    Did some more work outside with the 11-24L. Sometimes on 24 it will hunt. I think that if Metabones for the IV, which is what I am using, does an update, which they haven't for the IV to A7RII, things could be better. Using the 11-24 on manual focus and the magnifier I can really focus just about as fast as the 5DIII with this lens and if I want something truly specific, the manual focus and magnification is even better. For general stuff the auto focus is working about 85 to 90 percent of the time and pretty fast.

    Re: A7rII with Canon AF database reference.

    Just tried my year or so old Commlite EF-NEX adapter + just rec'd A7R2 with the following lenses/results. Used AF-S center point medium.

    1) 500 f/4 IS MK I - Inconsistent focusing. Works slowly with very high contrast subjects and not at all with other subjects. Electronic controls work. Did try AF-C on this lens. No go - doesn't work at all.

    2) 300 f/4 IS (ancient version) - Doesn't AF at all. Forgot to check aperture control, etc.

    3) 100-400 MK I (ancient version) - Doesn't AF at all. Didn't bother checking aperture control.

    4) 70-400 f/4 IS - Interesting results. Very fast AF at longest focal length, slow, sort of stepped contrast detect AF at shortest focal length with AF speed improving as focal length increases.

    5) 24-105 f/4 IS - Same results as 70-200 f/4 IS.

    6) 17 TSE - Electronic controls work.

    7) 24 TSE MK II - Electronic controls work.

    8) 12-24 Sigma MK II - Seems to work OK. AF not lightening fast but pretty quick and seemingly accurate. AF speed not focal length dependent as on Canons above. Full electronic control.

    Hope somebody finds that useful!

    Cheers!

    Re: A7rII with Canon AF database reference.

    This is a great thread as I have a bunch of canon lenses. I'm still waiting on my camera (didn't preorder due to lots of traveling) so don't have anything to contribute yet.

    One suggestion I have is to start a google docs spreadsheet and make it public.

    Re: A7rII with Canon AF database reference.

    spence-- I'm using the metabones iv adapter with the latest firmware update.
    Btw, I saw on the FM forum that someone linked to a review that stated that the 400 5.6L not only worked but was very fast. I just tried mine again to make sure I wasn't on crack and I still find that the 400 just hunts and does not work. I will take it and the 70-200 and the 24-70 out one day this week and try to see how it feels in normal shooting in different lighting conditions. Offhand, I've already found that lenses that work might have a little trouble here and there in different lighting but I think it's better to spend a little more time with them before trying to say anything definitive.

    To be honest, I never used the 400 that often anyway and am going to sell it. It's sharp-- especially for the money. I just don't use that focal length enough. And the lack of IS was limiting at that focal length (for me anyway) and though it gets me nowhere close to 400mm, I would usually shoot with the 70-200 and 1.4 tc instead.

    Link to page on Metabones site. Firmware Window or Mac option on right.

    I just tested a Canon 20mm F2.8L II, and a 50mm F1.4. Both change aperture and focus (slowly) with both the Metabones IV and Fotodiox adapters on an A7II. Based on what has been reported with pre-release sample A7RIIs those lenses should work with much improved AF on the A7RII. Adorama confirmed mine is in the que for shipping. Should get here Friday or Monday.
    I find .41 but not .42. .41 was done before the A7RII was released so it is not optimized for the II.

    Ops. That was a typo.
    Current version is .41 and it was available before the A7RII.

    My A7RII arrives Monday and testing with the EF-E adapters is one of the things I intend to address.

    Re: A7rII with Canon AF database reference.

    2006?? That's terrible. One of the most awesome things about the A7RII was the fact that I could get a 28mm 1.8, a 50mm 1.4, an 85mm 1.8 and a 100mm 2.8 macro more or less for the price of a FE 35mm 1.4. None of these lenses was released after 2006.

    I contacted Metabones and they have just gotten their hands on the A7RII so they will work on any FW updates but it will be a while with the Metabones IV for EF lenses, which is what I am using.

    Re: A7rII with Canon AF database reference.

    A7RII arrived this afternoon.
    I went through my collection of Canon lenses with Metabones IV and Fotodiox adapters.
    Results similar to others. I did notice that several lenses changed performance characteristics when the AF was changed from Phase to Contrast in the menu.

    In no case did it change a lens from poor to good. Maybe to less bad.

    The one lens that seemed to work best was the 35mm F1.4L.
    This is a lens that was designed well before 2006. With Phase AF it was quite fast. At least as good as on Canon. Contrast was not as good.

    55mm Macro focused OK on Phase with Metabones, not at all with Fotodiox.

    All the lenses had the aperture work so at least they are useable in MF.

    The 100mm F2.8L Macro does not work. That lens is after 2006 so not sure how that date figures into the equation.

    Tomorrow will spend some time in the field with camera and native lenses.

    I don't know if I mentioned this. The 200L f2 works pretty well. But not like on a Canon. Not that a lot of people have this lens. It is a beauty though.

    Re: A7rII with Canon AF database reference.

    I am wondering if amyone has ahad any luck with the 400mm f5.6? I have the Fotodiox adapter and it works beautifully with 24-70II and my 70-200 f4 but it doesnt do anything with the 400. I believe the 400mm is only 4 years old. Thanks

    Ebbtide posted above that the 400 F5.6 was a no-go with his Metabones Mk IV. This guy though says his 400 F5.6 worked great with his Metabones Mk IV, but he's unable to test further any time soon. Another guy on that thread is renting a 400F5.6 to try himself.

    Contadictory information so far, but it doesn't look too good. I guess there's still the Viltrox to try?

    Hi Spence, I just stumbled on this in the FM forum which I put in quotes below. It's about problems with the 100-400 ii, not the 400, but I'm wondering if a change in settings might affect AF on the 400 or any of the other lenses that might be problematic.

    "I have a Metabones IV with current firmware and tried out my Canon 100-400 L MkII lens on the A7RII.

    When I first set the 100-400 up on the A7RII I was disappointed with auto-focusing at distance with the mm set much beyond 300. While lock on was reliable at 100-200 - it started to hunt more as I moved from 200-300 and by 400 was hard to get a lock on contrasty subjects in daylight. If I first achieved near focus at 200mm, then zooming in somewhat worked - but was not reliable.

    Just playing around with the camera, I noted that the Steadyshot was On but selecting it said "Invalid with this lens. If the lens has a Steady Shot switch, perform the operation from the lens". I thought this was curious as I expected the Integrated stabilization to work with non-Sony lenses.

    In any case - selecting Steady Shot Setting and setting Steady Shot Adjust to Manual and the SS Focal length to 400mm seems to change the behavior of the autofocus at 400mm to the point where it will always focus - and do so quickly if the range is similar. Larger differences in range - such as 3 m to infinity will cause a slowish crawl to focus - but it always achieves focus.

    I have no idea why this works, but I've played around with it a bit to check if it was not a happy illusion because I so dearly wanted the 100-400 to work on the A7RII.

    I'd like to see if others with this combo experience the same. I note that handheld images of distant aircraft shot with this combo show amazing detail. (note I posted this in another dpreview thread in similar form)"

    Re: A7rII with Canon AF database reference.

    Very interesting, Ebbtide. Thank you for posting. I'm currently in the 'awaiting more info' stage. I have an A7RII sitting on my table, unopened. I'm going to do a complete system switchout, but not sure if I go with the Sony, or head towards a Nikon D810.

    Autofocus with the Canon 400 f5.6 is going to be a big factor for me, since that's my go-to Birds lens, and would probably put the Sony over the top. Eagerly awaiting more reports

    Re: A7rII with Canon AF database reference.

    People with 100-400 II might try this:

    I have a 100-400 I:
    With Metabones 3 did not work at all. Seemed a communications error
    With Metabones 4 and .41firmware worked fine at shorter focal lengths (<300?) but could not lock on at 400 as reported by others in this thread. THEN I moved the distance switch to 6.5m-infinity and it worked fine. Cannot select MF from camera (only AFS or AFC) but can from lens as well. IS and everything worked fine.

    Re: A7rII with Canon AF database reference.

    Just put my penny's worth in here : Metabones IV flocked

    14mmL II - wonderful
    16-35mm II - AF fine all focal lengths
    17mm TS-E - fine
    24mm TS-E II - fine
    35mm F2 IS - wonderful
    50mm 1.2 - faster and more accuarate AF than my 5DIII
    85mm 1.2 Mk 1 : faster and more accurate than the 5DIII
    70-200 F4 non-IS : fine all focal lengths
    70-200 F4 IS : fine all focal lengths

    Just a comment for those that do not realise just how good the focus can be. Both my F1.2 lenses struggled on the 5DIII to get a high keeper rate at F1.2. The Sony manages 80-90% - just struggles with some surfaces. When this happens, I just press manual focus button and let the edge-detect light-up when I get good focus. Works amazingly well.

    Re: A7rII with Canon AF database reference.

    A7rII. Metabones III, recently returned from China where it got the latest firmware update.

    Canon 17-40 f4L Fast/Accurate similar to 5DMIII

    Canon 24-70 f2.8L II Fast/Accurate similar to 5DMIII

    Canon 100mm f2.8L IS Hunts and misses just like the 5DMIII

    Canon 70-200 f2.8L IS II Fast/Accurate similar to 5DMIII

    Sigma 50 f1.4 ART Fast/Accurate for 3 exposures then locks up or the AF function goes into a holding pattern. This last for a few up to many seconds. Nothing seems to relieve it. Turning off and on sometimes but not every time. Sometimes, shooting with the EVF for a few then switching to Monitor cause AF to stop working. Can take many seconds to unlock. Sometimes the EVF and Montior will go black and nothing works. This only happens with this lens.

    FYI, the Metabones "Free" firmware upgrade isn't. They ask for $35 for return shipping but you also pay for the "to them" shipping. This is around $100. When I asked the FedEx clerk why it cost $100 to ship it to them and $35 to return it, he said Chinese Customs and Duties. Now this is for an RMA basically. So the "Free" upgrade will run you about $135 out-of-pocket.

    Re: A7rII with Canon AF database reference. Old on New

    I don't think I've posted here before, but here goes:
    So far:
    Canon 70-200 f4 IS very good (4/5 we'll say) with AFC I can do BIF
    Canon 500 4.5 (the old one non-IS) very good with AFC BIF possible
    Canon 400 2.8 IS (first IS version) DOES NOT WORK any way I try, no go with AFS either but manually focuses
    Canon 200 1.8 Manually focuses (remember it's focus by wire)

    The bike (70-200) looks weirdly sharpened here, but the bird (500 4.5) is reasonably accurate
    More later

    ? regarding the lenses that are not compatible:

    Do the lenses that "do not work" ....

    Work in MF mode or are they completely unusable?

    Are there other limitations? Not able to change aperture or send focal length/aperture info?

    Just curious what "doesn't work" means in this context.

    Thanks

    Hi I wasn't clear enough... The thread is about autofocus, so that's what I'm commenting on. Neither the 400mm IS nor the 200mm 1.8 autofocus in either AFS or AFC. A surprise when the old 500mm 4.5 did so well. (Metabones IV). They do manual focus, and all the typical EXIF info is there such as lens ID, aperture, SS etc. One wonders what magic part is missing in lenses that don't communicate with the A7rII body yet do so with Canon bodies. Both those lenses above are fast and accurate with 1D{1-x} bodies.

    Re: A7rII with Canon AF database reference.

    Sony Art 35 and 24 do work great with Metabones IV 0.41 but for like 50-100 frames in continuous shooting mode. After that they "loose" AF and it's really hard to make them work again. Detaching adapter, lens, pulling the battery does not help.

    17-40 on the other hand is flawless. Works all the time.

    Re: A7rII with Canon AF database reference.

    Recently the camera locks up on MF as well. I can get 3-8 exposures before the EVF and LCD go black and the camera will not respond to anything. When I turn it Off a few seconds pass when the last image captured displays on the LCD. This is when the camera is OFF. When is OFF not OFF? Now I am concerned there may be an electronic communication issue that can harm the camera. Anyone else having this issue?
