+1 ... true, the EF 85 f/1.8, does work very well on my a7 too.sdsr said:I rather doubt I'll get this one again, though, as my Canon 85 1.8 works so well on the A7s.

I have the ZEISS FE 24-70 f/4 OSS lens and it's a nice lens and does a decent job ... but yes, the quality/price ratio do not match ... I think $800 is a fair price for that lens and anything above that is not really worth it (I paid $1047 and definitely feel, it's not worth that much ... but I do like its small form factor, it is just a tiny bit longer than the FE 28-70).Albi86 said:Reviews on the 24-70 are not flowing as expected and the few I've seen seemed unimpressed by the quality/price ratio.

I don't have any experiece with the Sony 85mm f/2.8 lens but a few days ago I came across this blogpostsdsr said:I've read good things about the inexpensive Sony ff 85mm 2.8, but it's no longer inexpensive if you buy the right adapter for it and I'm not sure how many other Sony/Minolta lenses I would want to acquire to use with the adapter. Nor, for that matter, do I know whether, aside from focusing faster, that Sony lens would have any advantage over my Canon 85 1.8, which works really well on the A7/A7R. Does anyone reading this have any first-hand experience with that Sony 85mm lens?

Thanks, I did try accessing their site with Chrome, Safari, IE & Firefox ... all of them were returning similar error messages ... but it seems to be working now.sdsr said:Rienzphotoz said:Ever since I got the Sony a7, I've been visiting the www.sonyalpharumors.com site almost everyday, but since last night the site seems to return the following error message:

We seem to be reading the same blogs, presumably for the same reasons! I was unable to get onto the site yesterday via Firefox but had no problem with Chrome, and when I closed Firefox and reopened it the site worked just fine again. I just tried it in Chrome and it worked for me again. Try closing your browser and opening it again, or try a different browser and see what happens.
(As for soundimageplus, much as I enjoy following his experiences with various cameras, and for all that his comments usually make a lot of sense, I don't find his photos very helpful because I find the way he processes them to be, to put it politely, not to my taste.)
Great work putting it all together drjlo ... thanks for sharing ... personally I prefer the Metabones, because all my lenses auto focus with it (except 50 f/1.4), also the tripod mount can be easily removed, so the adapter becomes smaller and a tiny bit lighter.drjlo said:Researching into AF adapters for A7R, here are the apparent choices:
The ones without AF are pretty cheap, but there are quite a few that preserve AF, IS. From researching these in an effort to find a reliable one, the user experience seems to be that AF is similarly slow via all of them, and each has different electronics/software leading to one working better with some lenses while another adapter may work better with other lenses (Canon or third party).
Metabones Mk III adapter seems to be the most popular with most user reviews but also the most expensive at $400. It does not work with all lenses at all, however:
"Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus."

My next choice would be RJ Electronics one which is cheaper with good user reviews available. Some claim it gives sharper results than Metabones III (how?) and works with older Canon lenses unlike Metabones. RJ admits it does not work well with Sigma lenses. I read one user who said that Canon 100L Macro did NOT AF when focus limiter was set to 0.3-0.5m (Macro range) but AF was fine at other settings including "Full."

This Viltrox zinc-alloy one seems okay as well. I have a Viltrox Canon EF to M adapter which works OK though a bit loose on camera end. One can find a couple of user reviews on line, so at least you know it "works."
I found a video on Youtube that shows AF speed with Viltrox adapter and Canon 17-40L.

This Chinese one is claimed to be made from brass with AF intact. Unfortunately, no user reviews can be found.

This "King" adapter looks interesting as well but again no reviews can be found.

Thanks from me, too. So far my only AF problem with the Metabones is that my 70-200 f4 IS had a hard time focusing at 200mm. (Maybe it didn't help that it was below freezing when I tried it; if it ever warms up significantly here I'll try it again!) No problems with 24-105L, 100L, 85 1.8, 40mm pancake, or 28 IS. The only Canon mount Sigma lens I own is the 50-500 OS, but I can't imagine ever wanting to attach that monstrosity to my A7r!
Even if it does not auto focus, the good thing about the A7/R is that we can use focus peaking, which is much faster than auto focus with the adapter ... and focus peaking on the a7/R is very easy too ... if you haven't tried it already, try it and you'll like it.drjlo said:sdsr said:Rienzphotoz said:Great work putting it all together drjlo ... thanks for sharing ... personally I prefer the Metabones, because all my lenses auto focus with it (except 50 f/1.4), also the tripod mount can be easily removed, so the adapter becomes smaller and a tiny bit lighter.

Oh, but do try the Sigma on Metabones and let us know if it autofocuses AT ALL, however slow.
It seems awful difficult to find an adapter that will work decent with Sigma lenses, which is a shame since I can see the Sigma ART lenses may on people's minds for A7R.
Congratulations, may it serve you well. To change the focus point:drjlo said:
