In about 30 shots, this was the sharpest. Still learning with this lens (Tamron 150-600mm f5-6.3). Even at f10 there is still shallow enough depth of field to cause softness. Eyes and tip of nose soft, but bridge of nose more in-focus. I'm not happy about the level of color aberrations. I have to heavily correct in lightroom. And there are still some I can't figure out how to get rid of (like on the deer's forehead)

Although this was hand held, I was hoping for better sharpness. I cropped slightly...probably looking more like 750mm (guessing).

I get much better sharpness with my Canon 200mm L IS II zoom lens, but then I have to 100% crop or more and loose too much detail. The Tamron @ 600mm, although slightly soft, is still better than cropping my favorite 200mm Canon lens.
