Camera: Nikon D80.
I was told yesterday that a 10mm lens will be equivalent to a 16mm lens if i put it on my camera.. but someone else told me it's the other way round.. that a 16mm lens will be much wider.
I currently have an 18mm lens, so if it's only 16mm it wont be worth spending 拢350.. or is it a very noticeable difference? All Nikon dSLR cameras have a 1.5 focal length multiplier. If your lens is one of the standard Nikon zooms:
18-55mm effectively becomes 27-83mm
18-70mm effectively becomes 27-105mm
18-125mm effectively becomes 27-188mm
18-200mm effectively becomes 27-300mm
and a 10mm lens effectively becomes 15mm.
At any rate, the various 18mm zooms go wide enough for most people but they don't suit everyone. If you shoot a lot of landscapes, or building interiors.... if you find that the wide angle of your current lens is a restriction, you could probably do with a super wide angle zoom. The difference through a D80 viewfinder between an 18mm lens and 12mm lens is enormous.
Nikon makes a fantastic 12-24mm zoom. Sigma also has a very good 12-24mm zoom. For less money (and lesser image quality), you can get a Sigma 10-20mm, a Tokina 12-24mm, or a Tamron 11-18mm. This review goes into more detail: http://www.nikonians.org/nikon/nikkor-12... go to the link below for recommendations The D80 is a crop sensor, so your wide angle lens will be less wide, not more, so your second person is wrong.
Nikon's 17-55 2.8 is a great lens, if you can afford it, (About $1200)
The 18-70 kits lens isn't a bad lens.
Tokina has a 12-24mm that is very well thought of by many users
Ken Rockwell has lots of lens reviews on his website. |
