Hello from France, I use a NEX 7 with legacy lenses (AR Hexanon, Gottingen Isco, Lester A. Dine) with very good results (for me), I bought last Thursday an used A7 II (like new 1295 € instead of 1700) on a French resellers website. I went to test my stellar 2/35mm Hexanon, to assess those results to its true focal. Returning, what a disappointment, in some photos overexposed faded spots appear randomly. Sunday I did a test on all my lens and the result is as follows: 35mm and 50mm Hexanon problems, Hexanon 24mm and all focal lengths 105, 135, 180mm no problems ; reflections appear when the A7 is at a certain angle to the light source .. My fear is having purchasing an A7 II with a defect (position of sensor) what do you think?
Should I think that the problem comes from my chinese (not enough accurate) adapter rings? Have someone experiment such problems, I have to decide do send my A7 II back or cry my Hexanon 35mm dream.
