Sigma SD Quattro/ SD Quattro H


This comes earlier than expected. Sigma not just announced a replacement of their DSLR Flagship SD1 Merrill, it will be also not a DSLR anymore. It will be a mirrorless camera with electronic viewfinder and Sigma SA mount.

There will be two different models, depending on the sensor size. Sigma SD Quattro and Sigma SD Quattro H.

Sigma put a special website up for both new models:

Now I want to see the results against the Sd-1 Merrill. I've been getting closer to buying the SD-1M. But now I wonder if the Sd-1 M prices will come down to make it the better choice, or what the pricing will be for the new cameras. I have a bias towards supporting underdogs. So I can see the Quattro H as the top,of the life camera. The next two few months shoul be plenty of time of line up a few sales out of the Herd to give sigma another go. O think the foveon is great technology.
Hi Dirk. After we talked about the merits of DPM series (long time ago), I bought an SDQ-H body. I then sent it to a local expert for changing into Canon EF bayonet, so that I could use many of my old lens of other brands (Nikon, Rodenstock enlarging lenese, Hasselblad, and Canon). The results were generally OK, except for the wide lenses (image quality was good only in the central area). For some lenses, the image in the middle is often in a shade of purple while the edges blueish (but this is OK when I prefer getting B&W image instead). But I have been very happy with SDQ-H when I choose to use it to copy my large- and mediu-format film shots, using my Rodenstock enlarger lenses in combinition of SDQ-H's SFD functions. The resulted image quality has been much better than using my film scanners (Microtek and even Nikon Coolscan 9000 with a limited format of 6X9 film and sometimes the problem of uneven scan surface), both in terms of image sharpness and wider dynamics in high and low exposure areas (thanks to SDQ-H's SFD mode which works on 8 different exposures). I used to very disappointed with the film scanning results and I could not afford the very expensive commercial professional scanners for converting my film images into digital ones, but now the SDQ-H helps me marvelously and I have started to use my large- and medium-format cameras more frequently. I believe this film-dagital combination a very good solution to share with those who are still stick to film camera but with some headaches in finding acceptable scanning solutions. I just came back from Europe trips when I carried with me both the DPMs (1,2,3) and Toyo 4x5 film camera, and will convert the developed 4x5 B&W films into the exciting digital images using SDQ-H.


This makes me smile...

Sigma has come a long way since I bought my first metered camera - the Sigmaflex Mark1 at the end of 1976. As you can see, it's showing its age a bit... My next camera - the wonderful Contax RTS, one year later.

A bit late on this thread but maybe someone would find this helpful. I have a SD1 Merrill and a SD Quattro (not the H) and they are very different. The SD win for the details and for the superb viewfinder, and the SD Quattro win for the speed and for having less issues with the red channel.

. Both cameras are very capable but they also have issues. It's a love and hate relationship...

I gave up on the Quattro-H because I would not buy any more Sigma SA mount lenses and some ones I have would not cover properly the APS-H sensor size.
