Choosing camera lens

[TsPoet]

I'm really curious about why you think cropped is better -- I haven't heard or read about that.

For wildlife, etc, it gives you more zoom. That's the simple answer. There is more - DPMs, etc.
Here's a decent article on it

BTW - I share lots of my photos on G+, so you can see what types of pics I take there. Edit - guess you'd need to know my name, LOL - Torka is my real name and that's who I am on G+

I got my first digital camera before full frame sensors were available (Fuji S2pro)... when that camera died I got a D700 which is full sensor. Honestly it makes little difference to me. (I'm a professional photographer FYI) There are other reasons I really *love* my D700 that override any necessity to stand closer to my subjects...

Personally I'd stay away from Sigma lenses.... they have a very bad reputation for sketchy quality control and the construction is pretty cheesy. Certainly do not pay much for one if you go that route.

I was almost scammed recently a seller on Amazon (thankfully it *was* Amazon and the scammer had no recourse but to refund my money....) by someone who listed a lens as a Nikon Nikkor lens, then buried way at the end of the comments (and I think maybe even added after my purchase...) that it was actually a *Sigma* lens with a Nikon mount.... She thought she was being slick listing it on the low end of what an actual Nikon lens should sell for (which is not actually why I chose her.... it was because this particular model of Nikon lens is somewhat rare and it was between her's and one on B&H that was listed as a "7" - it is a lens that is out of production so used is the only way to get it and a 7 at B&H is second from the bottom.... pretty dang beat up...), but in reality her Sigma lens used isn't worth more than about $50....
