Re: IQ K100D or D40

I have been informed of the following by the Australian distributor of SIGMA lenses in Australia regarding lenses for the Nikon D40 and D40X cameras and it makes interesting reading:

New Nikon D40 is the first Nikon body without a built in auto focus motor. This means that any lens used with the D40 will need the auto focus motor built into the lens. These lenses are called AFS lenses. Sigma has a large line of compatible AFS type lenses. Most of these lenses have the HSM motor in them with the Exception of the 80-400mm f4.5-5.6 EX DG OS (optically stabilized).
The following SIGMA lenses are fully compatible with the Nikon D40:

10-20mm F4-5.6 EX DC
12-24mm F4.5-5.6
17-35mm F2.8-4 DG
50-500mm F4-6.3 DG
APO 50-150mm F2.8 EX DC HSM
70-200mm F2.8 DG MACRO
80-400mm F4.5-5.6
100-300mm F4 DG
120-300mm F2.8 DG
300-800mm F5.6 DG
14mm F2.8 EX
30mm F1.4 EX DC HSM
150mm F2.8 EX DG
180mm F3.5 EX DG
300mm EX DG
500mm EX DG
800mm f5.6 EX DG

So there you are:- 17 more lens choices than you might have previously thought.

My pick would have to be 30mm F1.4 EX DC HSM

On the other hand, if you are thinking of a Pentax K10D as I am, Sigma HSM lenses are not available for Pentax cameras. There are no plans for Sigma to make such a lens in the foreseeable future. ( But of course the large range of SIGMA Pentax mount lenses will work as normal pentax mount lenses).
