Hi
I'm looking to buy a 50-200mm or 75-200mm lens to put on my D90.
I am thinking about a Sigma 70-200mm f2.8 or a nikon 80- 200 f2.8 any advice would be most welcome.
 
I had the Nikon Push Pull and the Twin Barrell non AFS ones and both are excellent lenses, I only upgraded to the 70-200 as i wanted AFS and VR, plus the ability to use TC's on one :)
 
Got my Sigma 70-200 yesterday (non OS). Very sharp at 200mm. Fantastic lens.

I can vouch for the optics in the Sigma 70-200, never really had a problem with the lens, mine was canon mount but that shouldnt have caused too much of a difference. was using mine with a teleconverter to great effect. Slight loss in IQ though.

Can you explain to me the function of the (I think) exposure lock at the base of the lens, apparently locked for shutter priority and unlocked for aperture and manual. Do I really need to change this when switching modes?

Sorry if this is a noob Q.

Oh, its Nikon Mount. has a lot of numbers at the bottom you can turn the dial to also. I must sound such a noob lol. Apparently Mk1 had this and not 2.
 
That will be an aperture ring.

When you look it in, the camera will change the aperture electronically. If you unlock it, you change it manually by turning the ring, and you have to be in aperture priority for it to metre automatically.

Just leave it locked in and change the aperture via the camera, it's easier.

Is this better than the Tamron 70-200? Also can anyone relate their experiences (of either) on focusing performance in low light (indoors)?
