New Sigma SD1 46 MP

[Sachphotography]

Ok so I came across this....Any inputs...

SD1 DSLR - Digital Cameras - SigmaPhoto.com


Im a little surprised to see the 46mp number but it looks like it would be a good camera. Im curious about it now.

Have to wonder about higher ISO noise... still, it would be fun to play with.

Im really trying to figure out this whole X3 thing. The sensor is 15.6 X 3 equaling 46MP. I have never understood this. I believe Fugi did something like this on their cameras namely the S5 and it is one of the best portrait cameras out there ( If you can find one. ) and has the best dynamic range I have seen.

The X3 is due to how the foveon sensor works. Basically you have stacked photosites (3 high hence the "x3") that are sensitive to different wavelengths of light. It's different than the traditional Bayer type sensor where each photosite handles one color. Here's the Wiki of you're interested in reading up on it. . .

Plus, you get to use the supply of Sigma SA mount lenses! You know, the same mount used by a dozen or more users in each state in the Union! The lenses that have no resale value, and no spare parts! Woo-hoo! I mean, there must be a thousand or more Sigma shooters in America, so you can easily, easily dump this camera when you're done using it, and within three to four years, you can find a buyer who'll take it off your hands for a cool $75 or so.

46mp sensor, but I think it around 16-18mp output resolution. The way they market 46mp is kind of misleading.

Ouch... I like sigma..... I have never had any of the common issues you hear about. Wierd..... eh...who knows....

No more misleading than a standard camera which if you processed the same way would lead to a resolution 1/4 of the actual sensor resolution. The number quoted has always been the number of physical pixels on the sensor.

Foveron = stacked sensors so each of the three photo sensitive layers contribute to 1 pixel.
Beyer (traditional) = sensors laid in a RGBG grid and the data is then interpolated so you get the original resolution but thanks to interpolation you are usually unable to render a single point source.

This is also why some software used for processing RAWs for astrophotography will not actually interpolate and spit out a 3megapixel image for your 12 megapixel camera.

That's because he's talking about Sigma DSLRs and Sigma SA mount lenses. Nearly no one uses them.

Makes you wonder why they don't release the SD1 in Nikon F and Canon EF mount instead.

No s**t. That would have got me interested!!!

Yeah that would have been cool. Thats what Fugi did.

I know what you're saying but output resolution is what matter, not how many mp the sensor has. Nikon for example has always rated their resolution MP and not the sensor MP. In the real world, I don't care if my camera has 2 or 100mp, if it's output is only 4mp then it's useless. I want to know what resolution I have to work with. I've read up about this sensor and understand how it works. Yes it technically does have 46mp but I'm just saying, sigma never mentioned that it's just sensor mp and NOT resolution unless you dig into the tech spec (which is what I did) then you will see. Only testing and real world shooting will tell how this sensor will perform.

I don't think that's how it works. The SD15 is labeled as 14.X MP and still uses a foveon sensor. And I don't believe they've ever marketed their cameras as you're suggesting.

I've read that sigma were going to use Canon mounts for all their DSLRs - but when canon put the plans on the table along with the fee the negotiations broke down.

Honestly though sigma sell masses of lenses, on the lens front they are a big market player - the problem is that they've never pushed their DSLRs. I get the feeling that even though they continue to work on and release them they aren't trying to push into the DSLR market camera body wise.

That said they are pushing their lenses more into the pro market than ever before so it might be that they hope to one day push more sales of DSLRs once they lose the market image of being the cheap budget alternative lens wise

I know for a fact that their lenses will make them more money than their DSLRs will. The market is huge to sell lenses to everybody.
