You have to remember that with the smaller CCD array you basically cut out any edge distortion the lens may have. This is a bonus especially with wide angle lenses. I think this was the reason Sigma brought out the 15-30 EX zoom. However the multiplication ratio of these cameras vary some because some ,like the Nikon D1 series, comes in bodies with 2 different arrays with different sizes and therefore different multiplication ratios. Most fall in the 1.2-1.5 range. Kent Gittings

Sent: Monday, October 22, 2001 3:09 PM To: '[EMAIL PROTECTED]' Subject: RE: Pentax Digital NEWS! Part one The 'magnification' factor is one of the reasons I have not truly looked at a digital SLR. I have started to enjoy wide angle shooting and would not relish having to get a 17mm to get a 25mm. And I have heard of the problems with distortion with the 17mms. People have corrected this with photo s/w but again something I do not relish doing. Another aspect of the 'magnification' factor is that with only the central part of the lens being used people have been finding they have to really watch the shutter speed as any motion is more noticeable since the image is enlarged more to get the same size image as with a non-digital SLR. Though people point out that you are using the 'sweet spot' of lenses if you are not using toward the edges. By the end of next month I should have the possibility to begin spending some time with a Nikon D1x and D1H here at work. I am still looking at Pentax since most of my lenses are in that system and I love the glass I have.
