So today I thought I’d Give it a try on the Tamron 100-400 on my walk this morning with Roxie. I wanted to check out how the auto focus works and if I could get a sharp image with it.
The photos below are from that walk. It is sharp. These photos were all hand held while holding onto a leash at the same time. Not an ideal shooting situation. What I did learn is that for these kind of close photographs, the f-stop cannot be smaller than f/8. Auto focus did not work well at f/11 in darker conditions like deep shade. In brighter light it worked just fine. More testing on this required.
But I was happy to see the results and can now shoot with this combination with confidence.
1/400 at f/11 - 290mm
1/400 at f/9 - 480mm
1/400 at f/8.5 - 420mm
1/400 at f/11 - 350mm
Tri-X, f/8, and be there
