My 70-300 lens on occasion produces images that are not in focus when set to 300mm. I tend rule out camera motion because I am shooting at 1/1000 sec. and resting the camera on a solid rest. At first I thought it was because many of my earlier out of focus shots were wide open at f5.6. So today I tried shooting a sign that was 282 meters away and shot at 5.6, 8, and 11. The middle one, f8, was clearly out of focus. I am generally satisfied with this lens on my A7r2 camera, especially at the shorter FLs. The lens is generally sharp, and very easy to carry and use. Please see the composite of the three images. All are enlarged to 100%. Has anyone else experienced such issues with this lens or, with the A7r2 camera?
