Sorry, it's that time of year again where Sigma shooters get to sit on the sidelines and watch all the new releases.

Anyone got a wish list running?

I'd like to see a SA mount only, price reduced, factory run, lens buying website.

How awesome would that be? Up to date warehouse quantities straight from Sigma and a better price than anyone else could offer! Think if they had a trade in program? Trade in value towards purchase of a NEW lens? Come on Sigma!

What am I saying? It probably take a year for a backorder to go through...

Just whining a bit on waiting for a NEW 17-50mm to become available (wasn't even listed at B&H last time I looked). Was originally hoping to have one by this weekend... traveling across country next weekend for a wedding. Oh well.

Happy shooting!

Same here. I ordered a 17-50 2.8 lens from Abes of Maine on 8/16/2010.
They said they would special order it and it would arrive to me in 2 weeks.
Well as I write this, it's 9/15/2012! lol I have not seen the lens.

How about a ‘Certified Premium Lens’ ordering option for Sigma. Rather than have to pay extra for postage for the inevitable return for calibration – how about you just pay 10% extra at purchase (as an online ordering option) - and before dispatch, the lens is hand checked for focus accuracy so that you don’t get back/front focus (and check at ALL focal lengths) and also checked for centring accuracy so you don’t get soft corners on one side – all with a certificate to prove it, arriving with the lens.

This wish could apply equally to Canon and Nikon as well.

And a Sigma Pro program or something similar could also work.

Hi, Yeah the 85mm 1.4 was supposed to available in July too. But then again with the economy still in the tank probably shouldn't spend the money anyway. That's why I opted to wait on a SD15, make sure the job holds up.

Hi, That said if they came out with a real jump, a 1.3 crop, even with same MP count (but proferably bigger MP and bigger photosites), better focus (or focus screen) and the upgrades of the SD15 unless it would mean a divorce I would have to grab one.

Yep, Still waiting on the DP1x to be released. All sources seemed to be pointing to late Sep. Seems like a good time to do it. Although that little canon s95 might end up in my pocket instead before too long...always a waiting game.

Hello to all,

Somebody knows if Sigma will show some news cameras?

I remember that the last year President's Sigma or his first boss told that they want to do a new DSLR, and ok they show and present few days ago the SD 15 model but he said that they want to do a new DP 3?, or a new compact camera too or similar to DP1 and DP2 but with more innovations as more angular and tele and by the moment Sigma zero in this.

I'm waiting a new DP's Sigma model.

Thanks and best regards.

Seloge.

I wish Sigma would add a rangefinder to their little DP design.

I wish for:

a) Increased MP in Foveon sensor. Mostly because I am tired of hearing how small Foveon images are comparing to 14-16MP Bayer. Instead of constantly defending whether it's true or not, it would be nice if Sigma finally increased MP in Foveon. There is a rumor about CANON mirorless camera EIS60 with 22MP sensor and interchangable lenses. So I think it's time for Sigma to upgrade Foveon to keep up with competition.

b) Zoom DPx or with interchangeable lenses (DP3?). But I am afraid if they don't improve Foveon qualities (Part a), the competition in a small camera segment will be so-o-o-o fierce next year (just to mention EIS60 again) than even the most conservarive Sigmanians (like me) might start looking elsewhere.

Foveon - the future is here

Indeed, it would be nice to have a new Foveon sensor with at least 3000x2000 pixel images.
I think more than 8 Foveon MPs becomes kind of useless, except for crops.
Or, if not, how about being able to get HD video, at least 720p from it?

That would not be worth the effort.

Why not?

It's over 20% increase in resolution over the current sensor. Rome wasn't built in a day.

I guess you're right.
I just didn't see that it would give much more, at least in printing.

I know very little about what it would take to make a larger photo sensor, but I guess it would give them an 18MP rating if they could make one.

How do you calculate that?

I suppose it's pure math:

Pixel-per-pixel image size from the current sensor 1.8m x 2.7m = 4.8m pixels
Pixel-per-pixel image size from the "new" sensor 2m x 3m = 6m pixels

6MP / 4.8MP = 1.25 or 25% increase in image size (without any upsizing that is)

I suppose the assumption is that Foveon image would not visually suffer from up to 3x upsizing, therefore would stand up nicely against 18MP Bayer sensor (6MP x 3).

I calculated more like 13%, but I'm more one dimensional in my resolution ideas...

Your math right but your conclusion is wrong.

The easiest thing is to look at each dimension, since resolution - which was Radu's claim - has to increase in both dimensions if you want to retain the original 3:2 ratio of the image.

The F13 imager is 2640x1760 in terms of spatial locations. This proposal is for 3000x2000. That is an increase of about 12% in each direction. Since a Foveon imager can essentially go to Nyquist, it can be assumed that the resolution increase is only 12%.

In my opinion, to really make sense, they have to increase each dimension by about 100%, which would effectively double the resolution.

And, as I have said before, this would also put a stop to the stupid discussions about how many Foveon pixels equal so many Bayer pixels, etc. There are countless variations on this theme.

Of course, there will then be a new series of discussions about whether that imager is equal to imagers with twice as many pixels, etc. Yawn!

In any case, a 12% increase would not make much difference when printing.

Right.

Of course, we could discuss the size of the pixel, but perhaps that is not so germane at the moment.

But 12% does not get me very excited.

When you measure resolution, you say 640x480, 1280x720, etc.

So the total resolution increase would be over 20%, because it's not only on one axis.

You're confusing pixel count with real resolution. The issue is that 'display resolution' for monitors is referred to by pixel count.

Image resolution (real resolution) is discussed in lines per inch (or whichever linear distance unit you prefer), or sometimes in line pairs per inch. It's related to the pixel count of a sensor just the way everyone has told you it is (if you double the "MPs" you increase the image resolution by the square root of 2.

So to double resolution, that mean you'd need a 18 mp imager to replace the 4.5 mp one in the SD15. And you'd need good glass, and a very steady hand too.
