p.1 #1 · a7ii vs a7 - Rangefinder Lens Performance
Hi All,
A first pass at comparing the a7 and a7ii with respect to smearing and color shift on the 24 Elmar. My impression is that color shift is about the same, and that there may be a very slight smearing advantage to the a7ii. Note that the lens + adapter fit very tight on the a7ii, and there is a very slight play when attached to the a7. In the test shots below, I shot the 24 Elmar at f/5.6 (it really needs f/8), and applied the FF plugin corrections from my old a7 profiles to both shots.
I think it's safest to say the performance is "roughly the same" but it will take more scientific testing with various lenses to confirm that.
There are links to the large screenshot versions on Flickr below.

Thanks for posting this. I'm only going to use it with 35mm and up lenses if I get one.
Do you mind testing for sensor reflections? That would concern me more for my uses.

So...I retested the scene above with two other LM - E Mount adapters. There is enough noise in the tests for me to feel the two bodies are about the same with respect to smearing and color shift.
The a7ii is definitely much better with reflections! Here's a quick and dirty from my living room last night:

That seems consistent with other reports and is great news. I still hope to get mine later this week. If not I will have to wait until after the new year

The pictures need to have the same exposure, the light source has to be at the same location in the frame, with the camera and light source at the exact same locations for both shots. It looks like the A7 picture was exposed more than the A7II. Maybe Sony dialed in their lofty ISO numbers a bit on the A7II?

I agree there's a slight difference in exposure -- not sure why. But...I can tell you the reflections difference is obvious in person. You can look through the viewfinder and see the difference right away when scanning bright sources. To me, the a7ii looks about the same as the a7r with respect to internal reflections.
I'll try to do some streetlight shots once it stops raining a bit, but the improvement is pretty clear and very welcomed. It may not be perfect, but it's a lot better.

Maybe it's just me, but the improvement in smearing is definitely there. It's especially noticeable in the buildings in the first example.
Yes, but when I tried different adapters, the results were mixed. I'm pretty sure now there isn't a clear difference. I suspect the mount, adapter, and tolerances are affecting things much more than the sensor.

Thanks for the test and commentary about flare. This is v. good news for me and may be my tipping point, although it will be a couple of months before I spring for one.

Any luck with those? Anxiously waiting for the results!

Desmolicious, here's an inside shot using the a7 and a7ii, 35 Summilux FLE at f/11, and the same manual exposures. I think the a7ii is in a slightly worse location (lights closer to corner), so the difference may be slightly more. a7ii reflections are not completely gone, but are dramatically better than the a7. Anecdotally, i think the a7ii and a7r behave in a pretty similar way. Reflections are not 100% gone, but are certainly tolerable for me. I'll try to get some outdoor comparisons soon...

Thanks again Shelt. That really illustrates the difference well, unlike some really famous online reviewers who make no mention of the issue, even when queried.
That is a tremendous difference, and unless the upcoming A9/A7rii is something really really special, I think I've found my next camera.

Here's a quick and dirty set of some VERY bright LED streetlights during a rainstorm. Sorry for the sloppy shooting settings and focus, but I was trying not to soak my gear! The results were pretty consistent with the indoor shots above -- the a7ii still has some minor reflections in extreme conditions, whereas the a7 shows issues much more easily. Notice the smaller streetlight on the left...
