Hi all, Thanks for reading. Unhappy camper so far with the A7r ii. Bear with me as I am more familiar with motion cameras and shooting time-lapses with the canon 5D. Shot a test shot last night, noticed the edges were very soft - unusable soft. Did a basic test shoot this afternoon, tried to ascertain the issue. Would put it down as a back focus issue, but I believe lens adapters don't require any focus plane adjustments. Would welcome some feedback. Wanted to shoot wide open to test the extremities (not noise of ISO). These are from .arw using adobe DNG converter to lightroom, than exporting, than re-exporting to get the image on this forum. Frame 1. 16mm. Zoomed (camera) in for focus. (shot T2.8 1/60th 1000 ISO) Frame Frame 2. Cropped into top left hand of previous image. Notice focus going soft. Frame 3. Zoomed in on the long lens of the zoom. (shot T2.8 1/60th 1000 ISO) Frame 4. Cropped into top left hand of previous image. Focus still goes soft on long end of lens. I went further and increased the aperture to increase depth of field, and there was still softness (not as great, but still there). I tested the lens with an old camera, the canon 20D, and had no issue. Equipment used, Sony A7r ii, lens Canon EF 16 - 35mm L USM, Lens adapter Fotodiox Pro EF-NEX Auto (read great reviews). Prior to this day, my first day, shooting with the camera, I took it out to shoot my ball club, I used the same as above with the lens being the Canon 70-200 IS USM with an extender EF 1.4x II. I bounced around with auto-focus settings and ultimately went with peaking, but still felt all the images were slightly soft. Peaking, also threw me last night, (outdone my upload of images, apologies I can't show you), but the peaking and the image focus was way off. I took the image with a timer, so it wasn't affected by pressing the shutter button too. Have I purchased a lemon, or and I forgetting something important. To add, for anyone who does astro shots, being closer to the equator, do you need a faster shutter than 1/30th of a second to get sharp stars? Thanks all, G
