Im finding myself looking for an upgrade from my kit lens 18-55.
I have a nikon D40 and D70s and i am looking for better glass and sharpness of the same specifications.
Ive been looking at
http://www.warehouseexpress.com/buy-sigma-18-50mm-f2-8-macro-hsm-lens-nikon-fit/p1020682
and
http://www.warehouseexpress.com/buy-sigma-17-70mm-f2-8-4-5-macro-lens-nikon-fit/p1020681
Is there really much different between the two,apart from the f.
Any advice appreciated.
Or any other lens you can recommend... ?
