    Sigma(Nikon mount) Telephoto Zooms??

    Looking for a long zoom that I can actually carry on back country treks (my Nikon 200-400 is just a bit heavy and large). Considered the Nikon 80-400 but it's not an AF-S. Anyone have experience with Sigma Zooms - up to 400 or 500mm? There's a few out there with a new OS 120-400 just...

    KatzEye Focusing Screens?

    Getting old and finding it a bit harder to manually focus any of my DSLR's. The existing viewfinder set-up and screen isn't really expecting you to do much manual focusing - I miss the old split circle set-up on my film cameras.

    Discontinued? Sigma 80-400 OS

    Have thought about getting a bigger lens for wildlife shots but have been hesitant. The Nikon 80-400VR does not use an external motor for focusing and is slow.... it's also one of their first VR lenses so I was hesitant to spend the $$ required. Tokina's 80-400 is lacking any type of...

    Nikon lens for extreme close-up work?

    Most of my focus so far has been on landscapes/wildlife (outdoorsy vacations are our norm), some typical kids/family stuff and occasional sports. But, I'm thinking it's time to "cross-over" to one of my other hobbies - model building. I primarily build 1/48 scale models - so a typical single...
