Sony A7II + Metabones IV + Tamron 28-75 f/2.8 - Anyone with experience?


Recommended Posts

Hey,

 

I am currently using a Sony A7II with an LA-EA4 adapter and various A-mount lenses. My most used lens so far is probably the Tamron 28-75 f/2.8 A-mount lens, which I find to be amazingly good value and having an incredibly convenient weight/size for what it is. I am currently in the process - for good or bad, I am not sure yet - of changing to EF-mount lenses, mainly because of cheaper long glass and better resale value.

 

I have just ordered the Metabones Mark IV T adapter., but can not seem to find any reliable and up-to-date information on whether the EF-mount version of the Tamron 28-75/2.8 works together with the Metabones IV adapter. I seem to remember some reports of the built-in focus motor in the Canon version of the lens resulting in a worse experience than the A-mount screw drive version together with LA-EA4.

 

If anyone has any recent experience with a Sony A7II (or A7RII, I guess) + Metabones IV with the latest firmware and the EF mount Tamron 28-75, I would love to hear your thoughts on it.

 

I am also happy to take suggestions for other normal zooms I should be looking at, although nothing seems to come close to the weight/size of the Tamron for a normal f/2.8 zoom (510g). The more modern Tamron 24-70 f/2.8 VC is a whopping 825g in comparison. So far the best compromise I have come up with - in case the EF-mount Tamron 28-75 is not viable - is the Canon 24-105 f/4 L IS at 670g, but then I would be giving up the f/2.8 aperture...

 

Thankful for any advice!

Good luck finding a few respondents that have the exact

experience to offer you good advice ! FWIW, despite the 

dozen or so Canon lenses on hand, I use those only on 

Canons and happily continue using screw drive A-mount 

lenses on E/FE bodies via Sony's OEM adapters. Every 

nightmare scenario posted here concerning compatibility 

problems adapting Canon lenses to E/FE bodies leaves 

me loving my A-mount lenses all the more. 

   

If you actually get the exact experienced advice you seek,

congratulations. But if you widen your research to cover a  

general overview of using Canon lenses on Sony bodies,

maybe you'll cherish your A-mount stuff as much as I do !

    • Hi, Last year I switched from Nikon to Sony (A7Cm2) and this situation surprised me in an unpleasant way. When I travel, I record rather short 8-30 seconds clips, a lot of such clips. And found that these files are rather big because of rounded up to the nearest ~32MB. Different SD cards (64GB) fill up very quickly because of that behavior. Sample sizes for different durations of those clips, for example I have 700 clips with these "distinctive" sizes +/-, nothing in between 33,592,255 67,149,921 100,706,705 134,367,160 167,821,451 201,378,823 234,936,491 268,594,590 302,050,059 335,709,042 ... and so on +/-1000 for the smaller files up to +/-100,000 for the bigger ones rounded up to the nearest ~32MB  Different 64GB cards were formatted inside the camera with exFAT (allocation unit size is 128KB) Why is that? Is there some setting for that?  -- Piotr
    • In short: AF micro adjustment isn't needed in mirrorless cameras, so the option is irrelevant. In DSLRs, the focus module is in a different light path than the photosensitive plane. Minuscule differences in the lengths of these paths can be compensated for with AF Micro adjustment. In mirrorless cameras, the photosensitive plane also contains the focus points. So whenever the camera detects proper focus acquisition, the focus is also exactly on the photosensitive plane. That is, until you use an LA-EA4 adapter to mount your 500mm f/4 onto your A1, which uses its own AF module instead of the cameras AF system. I would strongly advise against going this route: you'll have a state of the art camera with an insanely good AF system, and then you dismiss it 'in favour of' a very dated and compromised AF mechanism. Better try the LA-EA5 if you really want to keep using your old lens.   Edit: apparently autofocus doesn't even work with the LA-EA4 on the A1. https://support.d-imaging.sony.co.jp/www/cscs/accessories/compatibility.php?area=gb&lang=en&mdl=ILCE-1&cat=7
    • Hi Everyone !! I intend to move to Sony A1 from Sony A99 ii. I plan to continue to use the Sony F4 500 G lens (A mount lens) with an adapter on the Sony A1. However, I cannot find the menu option to do the AF Micro Adj in the Sony A1.  In the Sony A99ii it was under the AF3 menu.
