Many thanks. I am tempted now to send in my A7r/2 as there doesn't seem to be any significant loss in performance for native FE lenses, right?
Regards, K-H.
K-H, most comparisons between stock and modded cam are with FE 35 and 55. With those two, the gain in RF is way more than the loss. I have not seen any test/comment on an FE 16-35 or a Batis 25 and I think those would be revealing (better yet a Loxia 21 ). If you don't have much FE lenses (or don't plan to), modding should be better.

Many thanks. In terms of FE lenses I have FE 35/2.8, 55/1.8, and 90/2.8, was thinking of getting the Batis 25/2, also considering the announced Voightländer wides.
My Leica M lenses that need the mod include 21/2.8, 28/2, 28/2.8, 35/1.4, and 35/2. I also have a number of 50 mm M lenses - Summilux, Summicrons, Elmarit - that look pretty good as is. My WATE and AA 75/2 and longer seem fine. The WATE isn't better on my M9 than on the A7r/2, so would minimally benefit from a mod.
I assume my R lenses (mostly tele), including the 28-90/2.8-4.5, won't be much affected by a mod.

If you can try the Batis before committed, that would be best. Any loss, however, would most likely disappear stopping down. Too bad, the Batis is quite sharp corner-to-corner WO.
Otherwise, it's a no brainer. I would get the mod if I am in your shoes ; you should see minor improvement with your R lenses. Your 50's would have no smearing like on an M platform, same with the 35's. Both 28's would give good result at WO (certainly no landscape here), and sharp at f/8 and f/11. I don't know about the 21, worst case would be good enough at f/11 (my G 21 was).

What do you think of the new mod? I'm sending my A7s in today for the AR treatment.
I don't have it back yet. Should be next week. I do have a FE28 I can test when I get it back (though I neglected to take any before pics unfortunately).
See previous post if you don't know where to install them.
Just made these so not much mileage on them yet. Feedback welcome, as always.

Update Nov 9: Did some shooting this weekend under tough lighting conditions with good results. Still tend to need large shift toward Magenta in LR, but results looked good.

thanks for doing all this work guys, this is great!
is there any chance you can post the midzones as well as the corners on the luxes (and maybe other fast lenses)? there are a number of lenses that the thick cover glass seems to dramatically accentuate the midzone dip (and a few where it seems to actually improve them...).

Derek, it might be true on the 21-28 Luxes that the midzone actually improves a bit on a stock Sony. However, I just checked both the Lux 35 and 50 ASPH, the midzone dip (around 11-12mm) is clearly worse on the stock A7RII.

i've only heard of it improving on the cv 35/1.4 and 40/1.4, i was mostly curious how much improvement the mod showed.

I think Ron noticed an improvement in his first test with the A7 and M9 with the Lux 21. Then recently, Reid shows that the Lux 28 actually performs a bit better on the SL than the M240. I do think the SL is quite close to a modded Sony, at least from what I have seen so far. Anyway, below is the midzone (11-12mm) crop on the Lux 35 ASPH.

thanks! any chance of posting the 50 lux too? maybe the other thread is a better place for it...
These are both Dual-Illuminant profiles and are (in my view) superior to the November 2015 versions, which I moved to archive folders.
As I had mentioned previously, I felt the original profiles where somewhat oversaturated, especially in the blues. These address that issue.
I only posted a profile made for Leica glass. I had previously made separate profiles for Leica and Zeiss glass, but the differences were quite minor (to me).
I'm still meaning to upgrade this camera to the v3 glass (as soon as get time where I don't need it) and will then post profiles for that.

In my quest for the most compact and qualitative setup, I'm thinking of getting a smaller/lighter 35mm on top of my Nokton 35/1.2 (that I love, but 500g and pretty big for a RF lens).
I'm looking at several options - I have a modded A7r with the v2 glass.
-Biogon 35mm: what I have seen here does not convince me really, even at f/8 the corners are not tack sharp with the modified A7r, so it must be really average at wider apertures.
-Loxia 35mm: I haven't seen any test with a Kolari A7, so not sure how the lens would behave (better or worse!), since it is based on the biogon 35/2 and modified to fare better on thick sensor stack.
-Summicron 35 v1: this seems to be a good option, but I would need to see pictures at f/2 on a Kolari body to convince me, it seems there's quite some Leica "glow" at wider apertures
-Summicron 35 v5: Expensive and seems to have quite some field curvature. Have not seen real examples with a Kolari body.
-Ultron 35/1.7: seems a bit big but the new version seems interesting. FWIW I find the lens pretty ugly, especially on an adapter.
-Any other recommendation? I don't want the FE 35/2.8 because of the aperture, f/2 is the maximum I'm willing to have.

I would expect the Summicron 35 versions - all BUT the ASPH which will likely continue to suck on A7 bodies even after Kolari modification! - to work well. I am using version IV, 7-element 35/2 very effectively on my unmodified A7R. Super sharp and zero corner issues with this lens on the camera body. My recommendation is to look out for this 35/2 version - sometimes you find decent deals for it online, but you might have to wait a bit.

Two obvious recommendations. First, the Zeiss ZM 35 f/1.4 performs very well on a modified A7r. Rich--naturephoto1-- and Jako both have lots of examples of its performance and it a very strong option. Second, if you want smaller you might try to new (as in within the last year) Leica M 35 f/2 ASPH. They tweaked this design so that it works better with digital. I'm not sure how it does on a modified camera. It still is at least somewhat weak on an unmodified camera, but it might be worth renting to check it out. Make sure you get the one that is modified for digital (i.e., within the last year).
). If you don't have much FE lenses (or don't plan to), modding should be better.
