I've been wanting to upgrade my basic lenses for a little while. I've got the 18-55mm f/3.5-5.6 kit lens as well as a Nikon 55-200mm f/4-5.6 AF-S VR. I didn't want to invest too much in the beginning in case I lost interest, but fortunately my interest keeps growing. I've got a D40 now, and will keep it for awhile. Eventually I'll upgrade, but for now I'd rather put together a nice lens collection. Anyway, here's what I'm considering: Nikon 18-200mm VR DX f/3.5-5.6 Nikon 50mm f/1.4 AF-S Sigma 10-20mm f/4 I considered going with the 50mm f/1.4D since I'll upgrade from the D40 eventually and can manually focus for now, but I'm leaning towards the AF-S. Actually thought about the f/1.8 as well, mainly due to price. I'm on a bit of a budget, so no $1000 lenses unfortunately. Also, I'll be getting these (or others, based on your recommendations) piece by piece. The Wife said "no way" to buying them all at once. So I can probably get one now, then I'll have to wait for Christmas/birthday/anniversary for the other two. So do these seem like good choices? I want to be flexible and have the ability to shoot almost anything, and from what I can tell and on my budget, these sounded like my best option. But I'm open to suggestions from the much more knowledgable and talented group here! Thanks!
