DPZoom - finally it becomes real... (new sensor & new lens = new dp)

[Ulvervs]

SIGMA filed patent of 18-50 mm F2.8 for APS-C sensor with very short back focus.

This patent may be for one of new DP's ... like DP Zoom...

Focal length: 17.55 - 48.47 mm
F No.: 2.92
2ω: 81.42 - 32.32
Image height: 13.49 - 14.20 mm
Back focus: 1.0000 - 22.4957 mm
Lens length: 126.29 - 166.99 mm

Ulvervs.

PS. With new sensor of course, note that new sensors were "always" first introduced in DP's before SD's.

So it will be slightly redesigned SDQ body without SD mount...

 

[ChristianHass]

Combine one of those with the SDQ body and a new high-readout speed sensor and we're onto something that looks like a worthwhile upgrade!

 

[Scottelly]

Awesome! Sigma just keeps going from strength to strength!

I guess I better focus on super-wide and longer lenses, because I'll probably buy this DP camera. 8-16 and 85mm here I come!

As four-thirds lenses fade from our collective memory, we should also keep in mind an adapter for all our old SA-mount lenses to use on our shiny new dp/dP/Dp/DP Unknown Sensor camera, eh?

Go on Sigma.

Hmmmmm Sony R1, Leica XVario, Canon G1X Mk3 : all Apsc fixed lens are all slow at max zoom.

Sigma DPZ constant 2.8 ?

A Dp Zoom with an improved sensor will be great!

A short backfocus could also apply to Sony E and micro 4/3s, which would make far more financial sense than a dp zoom (though it could be used for all three i suppose).

Incorrect. The sdQ and sdQH both were with new sensors, and both first introduced on ILCs.

Sigma's Lone Ranger digital photography philosophy has lots Goodwill from photographers from other brands.

Art lenses sure has helped spread Goodwill.

Yamaki San as well.

So yes perhaps someday DPy (DP yours) interchangeable E mount , m43, Fuji will pull all this Goodwill.

Yes, this is the most likely intent of this lens.

Not sure where the rumour in the title got its legs. Hopefully not on the assumption that new Sigma sensors always mean a new dp camera.

The term 'dp zoom' is an oxymoron because it betrays the entire concept of Sigma's dp cameras, namely, IQ-first.

 

[knoxphoto]

Looks very promising! I'd buy one if it's on par with the recent DP Quattro series lenses.

I don't agree at all. A zoom lens can indeed offer excellent image quality. The DP series are compact cameras, and a zoom version would still be compact, hopefully. It could offer excellent image quality, though maybe not quite as good as the primes and certainly it would not offer the same wide aperture - probably f3.5-5.6 in an 18-50mm with OS built into it. It would surely be cheaper and less bulky than carrying a DP1, DP2, and DP3. Add a new, better sensor and faster processor (than is found in the current DP Quattro cameras), and I think Sigma would have a real winner, even if the image quality is only "as good as" that from the DP1 Quattro.

True. To this day there is no DP camera with an H sensor, and the SD1 (and SD1 Merrill) where the cameras that had the first 14.7 MP per layer sensor that Sigma made, right?

"Unchanged from the first generation is a key element of the specification, the fixed focal length lens, which we selected as the optimal way to deliver the highest possible level of image quality." - Sigma, dpQ website

A zoom lens can indeed offer excellent image quality.

But not "the highest possible level" as per the camera spec and concept.

....though maybe not quite as good as the primes ....even if the image quality is only "as good as" that from the DP1 Quattro.

Then you get the unavoidable issue of zoom lenses having much (seriously, much) worse consistency from sample to sample. Many more disappointed owners, "I got a bad one" etc, and you can't change lenses.

Big step down.
