Sigma AF 20mm f1.8 EX DG with D100

[alex_j]

I'd like some feedback on buying a Sigma 20mm F1.8 EX DG Aspherical

Lens lens for use with a D100, or in fact any DSLR with DX format

sensor. I've seen some good reviews on this lens, and somewhat aware

of the pros and cons.... for example this page:

However, that's with a 35mm SLR. But with 1.5 cropping DX format

sensor, that 20mm becomes more a like using a 30mm lens with 35mm film

SLR. Anyone using this lens with Nikon DX format DSLR? Other pros and

cons.

<p>

I should mention, that I may get a 35mm film SLR soon, so while I've

got nothing against DX lenses, the ability to also use with 35mm is a

consideration.

<p>

Thanks in advance...<br>

P.S. not wanting start a sensor format war thread, just looking for

opinions about a lens.

Alex,

I purchased this lens when I bought my D100 back in November

2002. I kept the lens for about a month and traded it in on the

Nikon 20/2.8 and have never looked back. The lens was way too

big for me and the results mediocre. Digital requires the best

glass possible. If you are picky you will want to look at the Nikon

glass first.

I haven't used the 20mm but I frequently use the 15mm 2.8 fisheye Sigma on my D100

with superb results, it's really an excellent lens with it's fisheye effect tamed by the 1.5x

digital factor.

 

However I would agree that, if you can afford it, it is better to go with the Nikon glass.

Thanks for the feedback. Since asking the question, I have also seen a Sigma AF, 14mm f3.5 and a Nikon 20mm AF f2.8 lens (both near new) for sale, so have some other options to consider.
