Even if someone calls me a drama queen, I bought the A7r and really like the handling and what the sensor can give out at good conditions, but the flares/reflections I have detected with almost all of my lenses with more than 50 mm focal length is a killer criteria for me. Few examples:
Leica 2,8 60 Makro Elmarit (built in lens hood):
Leica 2,8 135 Elmarit (built in lens hood):
(sorry, that it is overexposed and focus is not set correct I just wanted to capture the effect and has been bored after realizing it)
Zeiss 1,7 50 Planar (Contax MM), lens hood attached, moving away from the light source:
Its way better using a wide angle lens (tested the 2,8 28 Distagon, Asahi super Takumar 3,5 35 and a PA Curtagon 4 35), I have been able to see it but much better than as with the other lenses.
It seems, that it is getting more worse using long focal length lenses and way better with short ones. I haven't had a chance to test a native lens, maybe it works much better.
I also did it using a Kippon Adapter (as for the pictures shown), a tilt adapter for EF Lenses and a Siocore automatic Adapter. Last one haven't had the issues but it already crops down to APS-C size as it does not have proper dimensions for Full Frame.
The effect does not only occur with point light sources, more light from one side is enough (for example reflection from white wall or mixed light in forests). Might be better with native lenses, but I would exclude the adapters, I manipulated one, using black velvet to prevent reflections caused by the adapter, and it does not help.
I have been able to prevent it by using something to shadowing the lenses in addition to the lens hoods, but the hoods has not been enough.
For all the lenses, I have been able to see this effect, I had no issues at all at the NEX-7, even without using lens hoods.
Call me a drama queen, but for me it is a no go criteria, as I often use long lenses, but the A7r may be a really great cam for people, which are almost using short lenses for landscapes.
It's sad, the sensor can really give great results, but for me, it's to hard to handle. Unfortunately I am over the returning back time and have to try to place over technical service.
