What lenses are compatible with D5000?
I'm fairly new to dslr and I wonder what type of lens to buy, I want a 15mm-200mm, but I've seen some very cheap, for example, http://www.play.com/Electronics/Electronics/4-/11066268/Tamron-AF-18-200mm-F3-5-6-3-XR-Di-II-IF- LD-Wide-Angle-Zoom-Lens-For-Nikon-Digital-SLR/Product.html? ptsl = 1 & b = Price & fb = 0 & & $ _ = ja TSID: 11,518 | cc: PRD |: 11,066,268 | Cat: Camera + Accessories and I wonder if I'm seeing things right or not? What I have to look at when choosing the lenses for D5000? Thanks
Indeed, many made by Nikon, Tamron, Sigma, Tamron, Sigma etc. are called "third party" responsible there. The lenses fit the camera through the frame. This is a good place to do research the lens. http://www.bhphotovideo.com/
