Sounds like you really want a zoom to cover the lower ranges. Your camera is an APS-C. Sigma has some new or lenses that look good. I am waiting delivery (later today according to UPS) of the 18-35 1.8 art series lens. A little bit pricey for me (but nothing compared to some of the Nikon glass.) The 1.8 is constant across the whole range so it is touted to replace several primes. They also have a 17-70 2.8-4 that is much improved over the older version I have used for a couple years and been relatively happy with. The 18-35 runs around $800.00 and the 17-70 around $500. Dpreview gives the 18-35 a gold award. And it is backordered nearly everywhere. Here is the dpreview of the 18-35 http://www.dpreview.com/lensreviews/sigma-18-35-1-8 and the 17-70 http://www.dpreview.com/lensreviews/sigma-17-70mm-f2-8-4-os-hsm Gotta love dpreview
Night shooting sounds like a FF job to me. A full frame senor is simply going to pick up more at night than a crop. But if you want to avoid that, then it would help to know what kind of budget you are working in and what you want to shoot at night.
The young need health insurance for the same reasons you have any insurance. In case something really baed happens. The young and healthy probably do not need health insurance that covers check-ups every six months. But insurance that covers a serios problem even with a high deductable is a wise move for the young. Otherwise a health problem that would otherwise just cost a deductable would destroy their (hopefully) long furture.
I have a question--what kind of pictures do you 28-70,24-70 or the 35-70? Since they provide for a narrow range of zoom and at the bottom end comes to a normal lens on a D7000-D7100 or are the for full size sensors only. There are so many choices in lenses out there I get totaly confused about them. Thanks.
I think the croop multiplier for the D7100 is 1.5 so the equivalent range of a 28-70 FF lens on the D7100 would be 42mm-105mm. Somebody please correct me, if I am off on that calculation.
Do you find it to be extremely sharp wide open or closed and on both ends? I love my d7100 but I am thinking I should get a lens that will fit a full frame eventually. Thanks!
Keep in mind that when you upgrade to a FF you might want to keep your old camera as a backup. Having a good lens for that is not a bad thing.
I just sent for the Sigma 18-35 1.8. It has gotten some great reviews for APS-C sensors. The 1.8 is constant and takes the place of several primes.
Was going to go with the Sigma 35 1.4 for when I "graduate" to a grown up sensor. Decided that when that happens, I will keep my T3i as a second camera since (by then) it will have little resale value.
