Sigma SD 10 Newbie Help UPDATE
(Steven Scharf) wrote in
om: But actually, worst is Foveon - they are trying to both eat the cake and still have it. They say that the sensor in the Sigma camera have 10 million full color pixels. I don't believe that Foveon ever claimed this. Hmmmm ... they have cleverly rewritten their web site. I earlier found what I claimed above without any problems. But now ... it is gone. The nearest I can come now is this ... http://www.foveon.com/prod_f7.html http://www.foveon.com/prod_f19.html Both says that they are "measuring full color at every point in the captured image". So - what is a point? Can there be fewer points than pixels? Hardly. We are therefore assuming that they mean full color at each pixel. Nothing else is reasonable. Further down they say that the sensors contains 10.2 or a 4.5 million pixel respectively. They also explain "pixel" as "pixel sensor". But that is a cheap trick. Why not call it "pixel sensor" then in the first place? Not only are they lying, they are deceptive also. They are trying to hide their lies in smoke. I think this is sad really. Their technology has a much brighter potential than such scoundrels deserve. /Roland |

Of course I want a p25 But why put it on a a large format camera? to get swings and tilts, rise and shifts. And where shall I get the money If I can answer that myself, I will let you know. And why is the adapter $2000? What is it doing? http://www.kapturegroup.com/ allows changing from viewer to back easily, and allows 'panorama' multiple images also and The Kapture Group STITCHING Back Adapter lets you attach your digital back to just about any view camera. The included drop-in insert can be rotated to portrait or landscape orientation. Shoot in the single capture mode or flip the lever to switch to the double capture stitching mode. In the stitching mode you capture two side by side images and stitch them together in your image editing software. Stitching of 2 captured images yields both a significant increased file size and field of view. Because your digital back can be oriented in either the landscape or portrait mode you also have the choice of 2 stitching aspect ratios depending on your layout needs. Kapture Group Sliding Back adapters incorporate a bright Beattie Intenscreen Plus focus screen. The silk-screened masking for 2K x 3K, 4k x 4k and 5x4 has both horizontal and vertical grid lines for preview and composition. /Roland |

But why put it on a a large format camera? to get swings and tilts, rise and shifts. If the image is digital, you can easily do almost everything in software, without any tilts, swings or shifts. The only thing you cannot do is advanced focus control. BTW - the large format lens is not as good as a medium format lens and it is much worse at the edges. So, shifts will lose more quality than doing the correction in software for a medium format camera. And why is the adapter $2000? What is it doing? http://www.kapturegroup.com/ allows changing from viewer to back easily, and allows 'panorama' multiple images also and ... Nice! - but $2000? No way! It is only some nice mechanics and a good matting screen. $500 sounds like a more reasonbable price. But ... I am not going to buy one nevertheless ... /Roland |
