Hi all,
I would like to update you all about my experience.
Sony A7R III v1.01 + Metabones V v0.57 + :
Canon 35 F2 - AF amazingly accurate and fast. Nothing more to tell, simply great.
Canon 16-35 F4 - Sucks so so so hard but so hard....cannot focus on shadows/dark areas. Bright area no issues, fast and accurate.
Canon 16-35 F4 was my main lens with Canon body, I'm kind regret in switching to Sony due to this AF issue.
Anybody else experienced the same result ?
I'm getting depressed ...
Have you tried the mc-11? I've got the 16-35mm f4 on that, it's not super in low light but if you can give it some contrast, it seems to be decent overall. Having said that, I wouldn't rate a cameras af purely on how it can handle adapted lenses, that seems a bit unfair as a whole.
I do tend to use a tripod and manual focusing for landscape in low light myself, as I've never found any cameras (6d, 5dmk3 etc) to be fantastic focusing in low light shadows
No no, it has nothing to do with A7R III nor with Canon 16-35. Simply the combination does not work with Metabones V.
The simple fact with my Canon 35mm F2 it worked so well I was expecting more from Canon 16-35 (since this last is my main lens).
I sold my 6D for A7R III, you have to admit, even though 6D has old technology the middle focusing point is amazing in low light (almost dark/no light), fast and accurate.
Kind disappointed with my investment. That's it.
I never expected to be mega fast as with native lenses but I did expect to focus. The currect situation is ...my Canon 16-35 cannot even focus
Not tried with MC-11 but I heard somewhere that Eye Focus does not work with it. True/False ?
By the way, I wrote to Metabones about this matter, hope they can reply me soon.
Ah I get you now, and yeah, I've heard it's quite variable depending on what lens is being used unfortunately. It also seems that it depends on the adapter being used, where lens A works well with the metabones but not as well as the mc-11 and vice versa. I wonder if this is one of those situations
The mc-11 has eye af on all the lenses I've tried so far, no issues there.
Keen to hear what metabones say.
The 6d center point is great yes, I still have my 6d that I use together with the sony.
I have had a few days with the sony 28-70 and the af was far better in low light with this than any of the adapted lenses. I'll be getting either the 24-105 or the 24-70 sony for this range for the af at some point.
Yesterday I've tested again and found out:
Under day light or low light situation, wherever the surface is smooth/surface with poor texture/low contrast, both lenses cannot focus. Canon 35 F2 can focus sometimes, but the fail rate can reach 50%. With Canon 16-35 F4 100% fail.
The surfaces I'm talking about are:
table, car's door, fridge, wall with shades (created by artificial light), cellphone, etc..
everything that looks smooth and no texture, it won't focus.
When there's
contrast/
patterns are notably different then both lenses have no issues in focusing.
It really pisses me off since the tests I did are not extreme, which means anybody can face these situations in a daily bases.
Metabones replied me this morning with some sort of stupid feedback: "have you tried Green-mode ?"
In Green-mode is even worse. Even with Canon 35 F2, the AF is so so so slow and the fail rate increases by 35-50%.
For me Focus scenarios coverage > focus speed. I don't mind in exchanging coverage for speed. (of course, not super slow). I'm happy and unsatisfied at same time.
Putting AF issue aside, the images taken are simly great. I visualize my images in 5k monitor and the image quality is simply astonish. For this reason I don't want to give up Sony A7R III.
I'm now researching more about MC-11, maybe can solve my problem.
Thank you for all your replies guys. Thumbs up
