Interesting and difficult test 3 different lenses , 3 different focal lengths and 3 different wide open apertures. Now all on tripods shot with the A7r with 2 second delay. I admit setting this up under my conditions was a challenge I normally can get extremely close but I maybe just a little off when moving the camera as far as image area, not my normal test scene and side light coming in on my face. But I am dead on with focusing as that really is the heart of it. So you may see a little area difference but each lens I focused on exactly the same spot. So here we have a 1.8/1.4 and a F2 assortment of lenses . Just for the record let me post the full frame of each lens at F2. I did not WB and they all have the same sharpening treatment. The only thing I did do is adjust the exposure to try and match each other as this fluctuates when shooting towards the wide open side of glass.
BTW watch the bokeh at F2 on each lens which is interesting.
Oh and yes folks I am squarely focused on the bird **** on the top of the lamp. Great texture. ROTFLMAO
