This little yoke looks tasty ,might be tempted to buy one myself.:D

Wonder how much they'll be looking for, for that thing? I mean, if you had a fixed 30mm F4 lens for your DSLR, how often would you use it?

(Fajitas is exempt from that question...)

Remember, tis not just your pixels that count

melekalikimaka

possible names for this camera

sigma 'overkill'
sigma 'pixel w***'




i'm just spitfull cod my d50 is 6

Fajitas!

f/4?

That's pathetic!

A 30mm 1.4, no problem, even 1.8...

But f/4?

Psssh!

Well, tis sigma... revolutionary approach to digisoap market...
originally they positioned it as digital rangefinder, but then something went wrong and now we have el-cheapo 30mm 4F 12mp with a peanut size sensor (so 12mp is gonna be software pixels rather than hardware pixels). And wait a second... IT IS NOT ZOOM! have you seen any prime camera in that market niche? me neither...

Looks like sigma's marketing department was too heavy on pochin, or whatever it is their corporate drink...

Well, given that it's a Foveon chip rather than a standard Bayer pattern one, you could argue that they're actually closer to hardware pixels, seeing as all Bayer pattern sensors have to go through an interpolation process (software) either in the camera or in the RAW conversion software to convert them to RGB triplets. On a Foveon chip each sensor site is layered, with each layer capturing R,G or B, so it's quite possible to fit more 'pixels' on the same sized sensor as a traditional Bayer sensor.

Also, I'm not sure whether the Foveon chip is as sensitive to the increase in noise that plagues the latest batch of multi-megapixel compact camera sensors which has been one of the big problems with such cameras.

Given all that though, I do agree that it's a very strange lens choice.

I was coming from a different end: small sensor size and a lot of pixels means pixels are sitting very close together. This attributes to higher heat and noise factors. Not to mentioned that this is digisoap and the sensor is working all the time. There was a trick - when you press the shutter on digisoap, it turns off the sensor to make it cool down a little bit, and then actually takes the picture. But still.

That's certainly true for traditional sensors .. maybe the Foveon chip is less sensitive to such effects, I don't know.

B0rG

doubt so.
same principle - you put units that change their electrical properties under certain light conditions. However, to measure such effects you'll have to put a certain current through them. Put them close together they start affecting each other. Plus the heat created by the current flow. Doubt they would go challenging rules of physics on a camera like this one :-)

The sensor is the same size as in Sigma's SLRs, therefore larger than any compact's sensors. And the Foveon sensor uses 3 layers so in fact it is a 4.5/5 Mp as far as resolution is concerned so I'd say noise should be minimal.

Yeah, it's a pity that Canon didn't go down the foveon road, I'd love to see what their R&D dept. could do with a chip like that.

If you decide to go for it Brian you'd basically be getting a wide angle only camera. Maybe you'd be better off getting a wide angle lens for the slr?

if the price is like 100 yo-yo - it would be excellent holiday snapper, but something tells me it's gonna be more...

I thought the idea of an image that size from a camera that fitted in the pocket ,was a great idea.

I'd say you could shoot with that camera and crop 60% and still have something to look at.
I know of an artist who shoots with a point and shoot and paints from the images. The lens seems like an eyeview of surroundings.
