I have been researching this topic for the last two months. I've tried the Tamron so far but now must decide between 150-600 native or the 100-400... or stick with my 70-300mm until Fuji comes out with something better.
I was torn between the Fuji 150-600 and the other sparse options but ended up getting the Tamron 150-500. I tried it out a couple of days on my XH2S. The first day I shot at the 500mm length in my yard on nice daylight it performed well. The images were beautiful! I thought it was a keeper.
Today on a group hike during overcast light I found that it is not such a smooth operator. The glide on the zoom feels like there’s sand in it, only just at times. Nevertheless, I wondered if there literally is debris trapped. The zoom in general is cumbersome for my small hands, but worst of all was the inability to acquire focus in shady areas.
I want to find out if it's me and my inexperience with larger lenses. (I've been shooting for 25 years but never wildlife until 2020). Or is there a problem with this copy.
Other issue: the back button focus failed to work a couple of times. This really was puzzling. So, I put my 70-300mm on and no issues - smooth as butter...
Curious to know if any other Tamron users have comments/feedback.
