Im a doctor most of the time and an amateur photographer (once in a while
) with the nikon D3100 and a standard 18-55 kit lens. Ive had a few instances where the lack of a telephoto became painfully evident to me. I would like to know two things...
is image/optical stabilization really essential in a telephoto?
is it imperative to buy a nikon AF-S lens or will a sigma do?
ive narrowed down my choices to the following two lenses..
1. Nikon 55-200mm f4-5.6 VR
2. Sigma 50-200mm f/4-5.6 DC OS HSM
Im a real NooB in this..so any help would be appreciated.. the reason ive shortlisted these cheaper lenses and not the more expensive ones is that i dont get that many chances or reasons to use the longer 300mm lenses.
I would also like to know if these would be well compatible with the D3100.
Umm..and i think the D3100 has a filter size of 52mm..so if theres a lens of say..58mm, is there some kind of adapter u can fit onto this??
Mr.Gordon..Im a big fan of ur very lucidly explained youtube videos.. would greatly appreciate it if you could help me out...
