When you have both and use both side by side the differences are there.
Yup. I have both, and the Tamron is sharper at 300mm, at all apertures. Heck, even at 5.6 it's sharper than the Nikon at 8 or 11. When some people have posted photos of what they consider sharp from the 70-300 VR Nikon I'm left thinking - wow, that really isn't all that great. I wonder if there is a large amount of variation between lenses.
And someone above complained about the lightweight build of Tamrons - it's actually heavier than the Nikon 70-300 VR. The VC is much better as well, and the AF might be slightly slower, but I cannot seem to tell. The only issue I have with the lens is that it underexposes substantially when in Matrix metering mode. I've sent it back to be fixed, but I can do more comparisons when I get back. Believe me, I wanted the Nikon to be better, but at this stage I cannot say it is....Show more →
This is precisely why I'm waiting for some of the main pro reviews to come out on the Tamron before formulating an opinion. I appreciate the effort, but no pro review is going to choose images like these to depict sharpness or lack there of. I've heard the Tamron is sharper right at 300mm and I've also heard that AF performance is considerably slower and less responsive than the Nikon, both could be true I don't know at this point. There is nothing subjective about the fact that the build of Tamron lenses is the lightest of all the three manufacturers. I saw that the Tamron weighs a little more than the Nikon, but that does not mean the build is superior. If it is, then that's a first from Tamron. It could be I don't know, since I haven't seen the Tamron in person.
I never buy lenses when they first come out until enough time has elapsed to have the accurate information to ferret through all the claims and get to the truth about a lens performance. For me that involves a combination of certain respected pro reviews along with consumer user reports. This will take a while and if the OP needs a lens in the next few weeks or sooner, I would suggest he try the Tamron and see for himself how it performs.
