UPDATED Comparison: Hasselblad 39C vs Sigma DP2M reloaded by Michael Ma

Hi Steve:

Thanks for publishing the quick Hasselblad/Mono/Sigma DP2 Merrill comparison (see that one HERE). I don’t know if you post follow ups but the post generated a lot of heated comments and one key issue people pointed out (rightfully) is that the Hasselblad was not designed to be shot wide open under limited light. I think everyone agreed that the Monochrom is incredibly sharp so I’m leaving it out of the comparison.

I took the Hasselblad and the Sigma out to the roof and shot a few pictures. And here are the results. This time, the Hasselblad is noticeably sharper and the image rendition is more accurate. However the Sigma followed closely and it is very impressive.

 

· Hasselblad 503 with winder CW, 80mm CEF Zeiss Lens, 39megapixel CF39 back vs Sigma DP2 Merrill

· Overcast but bright day, around noon time. Both cameras were shot at F11 and 125s, focused to infinity.

· Both pictures are right out of the cameras. No exposure/contrast adjustment or sharpening.

 

Hasselblad Shot. Notice the overall tone of the image. Smooth and warm. This is a little warmer in color than the actual day condition but came out very nice. The texture is almost creamy

Hasselblad

Hasselblad 100% crop. Very sharp and detailed. Some noise in the shadows even at ISO100.

Sigma shot. It is incredibly sharp but has that clinical look. Not as pleasing as the Hassey in the rendering. The sigma has a bigger DOF (the flower pots in the front are perfectly in focus while they are a bit soft in the hassey).

Sigma

Sigma normal size 100% crop. Again, very sharp here although not as sharp as the Hasselblad. The normal size conversion converts the X3F file into 4704×3136 file. The details are there and the colors are vivid.

Sigma double size: Sigma also has an option to export its files into “double size” TIFFs for bigger prints. This turns the file into a huge 9408×6272 file (over 100mb). This is considerably larger than the Hasselblad file. You could see the loss of details here but it probably won’t show up in prints under 40cmx40cm. (click it for full size 100% crop)

What does all these pixel peeing prove? Hasselblad owners can be rest assured that the performance of their systems cannot be matched by the Sigma Merrills, while Merrill owners can rejoice for owning such an incredible machine. It is unquestionably the sharpest tool in the ASPC sensor class. Although the system has its quirks and trade offs, when it comes to image quality (which is ultimately what we need), it can play with the medium format big boys. So, why not have both? A Medium format or a Leica Mono plus a Sigma DP2 would formidably setup for any demanding photographer.

Quick Comparison  - Leica Monochrom, Sigma DP2 Merrill and Hasselblad 39CF

by Michael Ma

Hi Steve:

Huge fan of your site. I am lucky to own two pieces of equipment that you have reviewed, so I thought I’d contribute. My Leica Monochrome just arrive today and I decided to give it a spin in terms of image quality. Both the Leica and the Merrill DP2 are reviewed in detailed on your website and they are renowned for their image quality. Since I’m lucky enough to have a loaner Hasselblad with the CF39 digital back on hand, I’ve decided to do a quick and dirty IQ comparison using the Hassey as bench mark.

Conditions:

Dim room light

1.7 meters to subject

All images had gone through only contrast adjustment, no sharpening

Hasselblad 39CF with 80mm CFE lens F2.8, F5.6 1/2, 1/4S

The Hasselblad yielded a pleasing overall image in terms of tone and rendering. With 39 mega pixels 49x36mm sensor, we don’t expect anything less. The 100% crop shows that even when wide open, the CFE lens is sharp and shows nice contrast. Note that the physical size of the Hasselblad image is almost twice as large than the Leica and Sigma.

Next up is the Leica Monochrome with Summilux 1.4 ASPH latest version F2.8, F5.6

WOW, the Leica is sharp! I don’t have a M9 to test the comparison between the mono sensor and the regular CCD sensor, but the 100% crop looks sharper than the Hasselblad shot and you can see the details in the canvas texture. The image was over blown in exposure but the details are still nicely preserved. Very impressive!

Finally comes the Sigma DP2 Merrill.

I couldn’t believe my eyes when I saw the pictures. It is clearly the most rich and detailed of all three. The photo was shot with the lens wide open at F2.8. Astounding details and color. Now look at that 100% crop. The texture of each brush stroke is so vivid. Beats the Hasselblad hands down.

Conclusion? Well this is a very clumsy test. But besides the poor testing conditions I think there’s a story to be told here. All three are great camera systems. The Hasselblad is older and the lens probably could have used with more stopping down. But this is also a 9000 dollar set up (used price). The Monochrome setup is 12K all in (when bought new). The Leica lens is incredibly sharp and the Monochrome retains so much details in the shadows. But the ultimate winner here is the Sigma DP2. At a tiny fraction of the price of either the Hassey or the Leica, it delivers the best results in color, details, and contrast.
