I have the Tamron 150-600 v1 and shot a lot of stationary birds, butterflies, BIF, and various landscapes with it over the past 4 years. Sharp and brilliant color in good light conditions, even at 600. In less than ideal light, I back it down to 550 mm. Love it and the price. Shoot mostly manual all the time.

I have the g2 lens and find it very stable and sharp in all ranges. I use it for action nature and find it to be excellent. I had been using a similar Sigma and find there is no comparison

Had the first generation Tamron 150-600, used it some on a D7100 and got good results most of the time. It was a lens for me that needed good light; it was not for marginal conditions such as a lot of overcast or marginal lighting. One irritating issue I had....soft images even when I thought I had nailed the shot. Example: early evening, a robin on a tree stump at maybe 75 feet away, image stabilization "ON", shooting from the driver's window of my vehicle with the engine off. Darn...every image was fuzzy. Even ground squirrels at less than 50 feet away, the lens would hunt. When I got my D850, I took that lens for a couple of test drives. Some of the shots I could not figure out what was in focus and what was not. Found an old barn less than 100 feet from the road, parked and set up the shots, engine off. Took shots at 150mm, 300mm, 450mm and 550mm; never cranked that lens all the way to 600mm because it was sharp. All the barn shots was not some to some degree when I blew them up to check them. That was the end of that lens; got rid of it and put the cash in a fund to eventually acquire a Nikon 70-200 FX FL lens and get a Nikon 1.4x teleconverter. If I want my reach, will put the 70-200 on my D7100. I am no longer a Tamron fan. Had a 24-70 G2, after testing sent it back to B & H. Have a Tamron 18-270, would dump it too except it's on an older DSLR that my daughter likes. The lens is fine for what she uses it for. Side by side with my Nikon 18-200 DX VR, the Nikon is hands down the better of the two.
