    A classic central NY November scene. sdQ + 30mm Processed with some other shots in batch mode using the just released Kalpanika Wrapper, which includes an exiftool executable to automatically transfer exif to the converted dng file.

    Re: Sigma sd Quattro Images

    Here is another image processed using Kalpanika x3f tool 0.56, inside Wrapper and then exported as a dng file to Lightroom. Best processing I've seen so far for Sigma x3f files. Click image for full size original.

    Just a note that Kalpanika Wrapper is now available for Mac and working well running the latest OS 10.12.1.

    Another furry critter looking for food around our garden. A young whitetail that appears to still be wearing a summer coat. sd Q with 17-50. Processed through Kalpanika/Wrapper to DNG and then Lightroom.



    The little one found something in the rock garden worth digging up. Same setup and development as above.

    At the bottom of the gorge where Enfield Creek emerges above the confluence with Cayuga Inlet. sdQ+17-50. Camera really struggled with white balance given the low light, bright snow, and warm sunlight seeping in from above.

    seems to be very unsharp at the corners, what f-stop did you use?

    f/8, but shot close range (about 3 ft)with camera pointing up at an angle. Also, corner softness is a known issue with this lens.

    Re: Sigma sd Quattro Images

    A shot taken with the Sigma 8-16mm lens on the sdQH with WonderPana filtration system. The latter is a new design with integrated locking collar so mounting and unmounting can be done with the lens on the camera. Shot below was taken with the NDG SE 0.9 rectangular filter and 145mm circular polarizer. Filter holder can also be used on other lenses that are threaded for filters by using step rings.

    Shot at 10mm but cropped to 4:3 because of corner vignetting. The 8-16 is best used at 12-16 to avoid this issue when using with the H sensor.

    Is that a can of Renaissance polish reflected in the filter?

    Yes, it is. I use it on glossy canvas prints that are framed without glass. Gives some protection from fingerprints and dust will not adhere to the print.

    I'm intrigued by the circular filter. Is that a polariser? Or stop filter?

    Yes, Louis it is a 145mm circular polarizer filter. The little brass posts on the edge are handy for rotating the filter.

    Re: Sigma sd Quattro Images

    I am very late to the sdQ and surprised that the last post here was in February 2017...2 years ago.

    I just received my sdQ with the 30/1.4 Art lens today. While I love the simplicity, small size and image quality of my DP Merrills, I am happy to have an EVF and much larger battery on the sdQ.

    I look forward to trying it out in the days ahead and have been inspired by the many excellent photos posted here.

    Contemplating a future lens purchase...perhaps the 24-105 Art.

    Gary

    PS: I have already made a first print from one of the few sdQ images I took today. Looking good so far.

    Re: Sigma sd Quattro Images

    Some of you may know that when I get a new camera or lens I often take a few test photos of a mural painted on the wall of Pete's Smoke Shop in Anchorage. The colors, especially on a grey winter day in Alaska, are enough to brighten my day.

    This was the first image from my sd Quattro that I printed this evening. These colors are very true to life. This is one of the things I've always appreciated about the Sigma Foveon cameras I have.

    Re: Sigma sd Quattro Images

    I love the many colorful images posted on this thread. Unfortunately, at this stage of the winter in Anchorage, color is hard to find (aside from the Pete's Smoke Shop mural). I'll have a few images to share later with more color than these.

    That said, I couldn't be happier with the sd Quattro and 30mm f1.4 Art lens. For the price of $899 USD new, I can't think of ANY camera/lens combo that can deliver this image quality (except for a dp Quattro and dp Merrill).

    Re: Sigma sd Quattro Images

    As promised...a little more color in this image.

    I fully expect that Sigma will release an improved Foveon FF sensor for its L-mount camera, but even if it is simply a FF Quattro sensor in an updated L-mount mirrorless camera, I would be happy with that and almost certainly buy it too.

    Re: Sigma sd Quattro Images

    However the images may look on a digital display, whether large 4k screen, high res computer monitor or tablet/phone, for me the ultimate test and goal is a print.

    I've been very happy with the 11x17 and 13x19 inch prints I've made from the sd Quattro images, including this one.

    Next test is a 17x22 or 17x25 inch print (the largest I can make with my Epson P800).

    Re: Sigma sd Quattro Images

    I don't have another sdQ image to share just yet, but I had an interesting (to me) experience comparing 17x25 inch prints of the Imaging-Resource.com still life test images from a dp2 Quattro (standing in for the sdQ and 30/1.4 Art lens), Fuji X-T3, Nikon D500 and D810.

    I printed the IR still life ISO 100 images without any adjustments (other than re-sizing to 16x24 inches at 360 dpi) on RRP San Gabriel Baryta paper. I then asked my wife (who has a critical eye and has looked a many prints over the past 20 years) to rank them from 1-4 on overall quality (color differentiation, highlight/shadow and ability to discriminate and record fine details etc). Of course, she did not know which image/print was from which camera in advance.

    Her ranking was from best to less good was:
    1) Sigma dp2Q
    2) Nikon D810 (a very close 2nd)
    3) Fuji X-T3
    4) Nikon D500 (more color aliasing seen in the very fine lines on the PS 69 Proportional Scale)

    This confirms my experience that the DP Merrill and now also the Quattro series cameras can hold their own very well (at low ISOs) with the 36mp FF Bayer sensor cameras I have used (D800e and the D810).

    UPS delivered the 24-105/4 Art lens I had ordered to Stewarts just before I left Anchorage on my way home. I had a chance to take a few snapshots before the light faded.

    These images look so detailed and I think comparable to larger sensors tha what Sigma installed in their cameras.
