Love the camera! Also have been shooting wild life and needed longer focal length and got SP 70-300 F/4-5.6 Di VC.
I had not tried the Nikkor 70-300mm f/4.5-5.6 and was in a hurry and the price of the Tamron and the lens felt right plus I was short of cash and Tamron was 1/32 the price of the Nikkor
Having used the Tamron lens for approx. 1 mos I have regrets about not trying the Nikon lens! The Tamron does not track well, Bokeh is not the greatest, seems to search allot when zooming in. Seems to click or slightly jolt when it finds its target?
Also short end of focal length is not wide enough perhaps 28-300 Nikkor would have been a better choice. When ever on tripod and I want a wider shot (wider then 70mm I have to switch lenses!
Last year I tried a Nikkor 70-300 on tripod and liked the results.
Has anyone had similar sentiments about this Tamron and or used the Nikkor 70-300
I bought the the Tamron during the winter, did not really test it till the spring and even after trying to fine tune the autofocus, I was at -20 and image was'nt clear, I brought it back to the store, they sent it to Tamron, they fixed the back focus, I did the fine tuning at -10 and since my pictures are sharp and autofocus is just fine.
