what to get?

mmmmmm

what to get

the nikon 14-24mm 2.8

or the much cheaper 17-55mm 2.8

I do currently have a tamron 28-70mm 2.8 on my camera.....I do really like it but although i think probably at times gives a more truer colour rendition i believe the nikons give a crisper colour range.

So do I first get the 14-24 as I dont at this point have a good lense that covers this range or do I first replace my tamron but then may possibly struggle to save for the other...as the other is so much more money

choices choices:(

Lou, as you know I have the trinity 14-24, 24-70 and 70-200 f/2.8 Nikkor lenses. For what I do I have found the most used lens to be my 24-70. If you are happy with the Tamron then I wouldn't buy the 24-70 Nikkor. However, that is by far the best of the 3 lenses. Just remember it weighs in at about 1kg though so its a brick to lug around.

You do have to be careful of distortion and lens flare with the 14-24 and from what I've seen it is a lot better suited to FX rather than DX.

I'd also look out for 17-35 f/2.8 Nikkor. Haven't played with one but they sound good. The 17-55 is a DX lens so if you are thinking of the future and maybe FX later on then this may be something to avoid. Other than that it is also a very good lens.

i get very confused derek is it the DX i should be getting for upgrading the body later on or the FX

[dmdigital]

DX is APC sensor size
FX is full frame (35mm equivalent).

My aim is to go over to FX with the next body I purchase (probably D700 or its replacement). Downside is 70-200 becomes just that and is no longer a 105-350 equivalent

[dullbird]

so do the fx lenses work ok on mine not being a full frame

[dmdigital]

Yes, your 70-200 is a full frame lens. The opposite is the issue. A DX lens will not cover the full sensor size of an FX sensor. To overcome this the FX camera bodies have the ability to lower the sensor area and take a DX picture but of course this also reduces the resolution of the image. I'll try and dig up a web link about it.... DX and FX Confusion by Thom Hogan (http://www.bythom.com/confusion.htm) might help

So how do I know when I'm buying an fx lense? as my 70-200mm doesn't state its an fx

it says its an AF-S, IF, ED, VR but no FX

[dmdigital]

In general terms if it doesn't say then its FX. Nikkor lenses will state they are DX. But other makes like Sigma, Tamron, Tokina will state they are "designed for digital". Sigma lenses that are for digital SLR are badged DC (for DX) and DG (for FX but will also fit DX - eg my 150mm Macro ( http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3283&navigator=5 )).
