Sigma is Still Doing a Foveon "Flagship", Does it Really Work? (I Mean Marketing-wise..)



It's a 15.36 MP x 3 Layers (~46MPs) Foveon Sensor in APS-C size, finally (but not 1.7X!). But since Foveon and the Sigma combination and combos had been proved to be a marketing failure in the past. I just wonder, if it really works for Sigma (and Foveon, which was acquired anyway) this time?!

Btw, I admire much the insistence and courage of Sigma the company. But however, I am not optimistic about the sales of this new camera, even it is meant to be a "flagship" (which still falls short of many things for being more updating)!

Till now Foveon was lacking resolution, while color rendition was not satisfactory to some, and on top of that, Foveon was slow to update their models. The main advantage should be light gathering capability, and resolution that is equivalent to twice the resolution of Bayer filter sensor.
Now I think Foveon have a really strong contender. To bad that Sigma is not the most adopted DSLR brand around (camera wise). Wish them all the best.

Actually no one else is brave enough to use the Foveon, not even to mention such insistence level that Sigma has! :-o

Maybe Sigma is making those Fov bodies only for Japan or their employees. Honest, never seen ONE anywhere while in EU or home (USA).. just unusual (self-serving?) adventure in today's crowded market, to say at least...

I hope they will make their Flagship a bit faster than they have been doing upgrades to their models and I'm really curious about that super foveon sensor.

Foveon sensor has problems that are not easily, if at all curable - basicly the stacked photosites create more (read) noise, lower QE (versus B&W sensors - don't know versus Bayers which lose about half of the light, some more, due to the filters), and hideous colour accuracy.

However, this new sensor not only shows how little DPReview staff understands photographing equipments (by calling is 46Mp sensor/camera, ignoring the differense of the definitions between pixel and photosite. Also it gives a very strong resolution by contemporary standards, though the lacking AA-filter will still ugly lego blocks when magnified lots (lots = more than 99% of shooters ever magnify they images).

In short: excellent resolution and almost certainly a dog in pretty much all other aspects.

The fact is that it's real to print 46 MP pictures from FOVEON without any lack of details. The resolution of SD1 will kill any DSLR with APS-C sensor now. And maybe FF too.

Anu, "pixel" means "picture element. Not necessarely in the ouput image. And not necessarely with 3 colors.

"photosite" doesn't mean anything. Use "photodiode" if you wish...
