As many of you know, I've been quite voluble in expressing skepticism about the 'qualitative' advantages of MFDB as regards its 3-dimensionality and extra crispness due to the lack of an AA filter.
Such qualities are clearly discernible, and I wouldn't deny they exist. But the price premium one has to pay for an MFDB system is a bit offputting, to put it mildly, not to mention the disadvantages of additional weight and general cumbersomeness of the system.
In a sense, it is therefore surprising that those who are already 'sold' on the 3-dimensionality of the MFDB and the additional 'crispness' of the images, should criticise the pricing of the SD1.
I get the impression, but correct me if I'm wrong, that the Foven design not only has the benefit of no AA filter, but the benefit of 'no need' to interpolate (or invent) image information because of the unequal balance between the number of red, green and blue diodes that the Bayer system has to contend with.
The 'qualitative' benefits of the Foveon system in this respect, disregarding pixel count, should exceed the qualitative benefits of MFDB.
Ray,
I don't understand, and it's not aimed to you, why people are seeing the grail to interpolate. They want reso on the cheap. It doesn't work like that. The SD1 is a stunning 15MP camera, and a good 20 ish MP interpolated. If you really want to take all the benefits of the Foveon you need to use the camera at its based resolution.
The moment you interpolate you loose quality, even if in the case of the Foveon you loose less in interpolation, you loose anyway.
You can say that after all it is a good performance that a 15MP camera would deliver a similar output of a 20ish MP bayer, yes, but where is the Foveon advantage then?
Well, the real advantage of the Foveon is that if you take 2 15MP cameras, the Sigma will be truly outstanding, but if you interpolate you'll end in a similar result of the Bayer. If you want to see the "miracle" Sigma is claiming, you need to keep the camera in its resolution wich is 15MP and compared it to other similar cameras on the market: the K5, the 7D etc...
15 packed in a small surface area is not the P65, not even a 20MP digital back. I think it's time to stop dreaming even if it's nice, even if it has 3 layers.
People want to see a sort of MF packed in a dslr... no, the Sigma is NOT the Leica S. It is very far, light years away in all aspects (sensor, built quality, features, image quality, value, image, pro service, lenses).
It's even far away from the Sony body wich is a truth pro body or the Leica M where you can mount on it the best glasses produced on earth.
So, if the Sigma had a large format sensor, it would probably smoke MF gear, but the fact is that it has not.
Also, the price, at that price or you have a brand that smells luxury and quality, or you get pro features. The SD1 does not have any of those.
People would like to feel that they finaly have MF quality for less than 8000euros and that the Robin Wood of the saga is Sigma. They might have a really big disapointment if they beleive so and sign the check.
It's like this sign I saw one day when walking on the beaches district in Toronto:
