Another SD1 review
Sep 5, 2011

A Japanese review of the SD1 with some comparison with a D7000 and a Hasselblad H4D-50 MS.

http://denjuku.gr.jp/review/201108/163.php

The Google translation isn't very good so I'm not making any assumptions. Perhaps someone here can give us the gist of it.

I read this review and realized that some of the terms don't translate well. However, the photos did not need any translation. The SD 1 held up well against the others. Personally, I think that the contrast was much better with the Sigma than with either the D3X or the D7000. I don't know what a professional would think, so I can only give my opinion.

Thank you for posting some of your photos in other threads. Wish I could afford one (SD 1).

Yes, color resolution is higher than any APS-C camera. So one and unfortunately only good information for me is, that the new sensor has it´s potential and Sigma can finally concentrate to other aspects of good contemporary camera for reasonable price...

A section showing fine detail.

Never quite sure exactly what to read into tests of unknown provenance but detail looks very good. On the downside, noise and dynamic range looks poor compared to the D7000.

You really need to try an SD1 for yourself!

Looking at the greyscale, the SD1 version - to me, on a calibrated monitor - looks correct. There are steps going into black visible, just subtle - the D7000 looks artificually boosted in the shadows, and looks to be less consistent in terms of grey accuracy. Particularly the section over the 7 on D7000.

This is borne out by looking at the file in Photoshop. The SD1 greys are pretty uniform, the D7000s ones are showing more variation (9th sector, for example - SD1 is 106, 106, 104-106, the D7000 is 131, 127, 124). What they've processed to present this, we don't know of course - but I do know it's possible to present more flattering results from ISO 3200, so I'm giving them the benefit of the doubt in terms of their process.

What they haven't done is got 255 white on the SD1, so I think they've very slightly underexposed there. The first white step is ~240 on the SD1 and ~250 on the D7000 section.

However, there's increased luminance noise on the SD1's blacks; obviously working from the web JPEG isn't idea for judging this.

What i don't understand is why are people compairing the SD1 to a £850 camera, the D7000! surely they should be compairing it to the D3x or the 1DS Mk III

is it that as the SD1 is an APS-C size sensor the D7000 is the only camera they can compair it to?

or is the SD1 so overpriced that they feel the SD1 should really be around the £1000 area.

I wonder why the SD1 seems to show better color resolution than the Hasselblad .
It's a $40,000 camera.

But doesn't Hasselblad has twice the horizontal and vertical pixels than the SD1? On their images it looks like all the cameras are the same resolution which is simply not true.

Nikon D3x images are looking better IMO but its a 7000$+ fullframe camera. I'm sure that high ISO are also much better in Nikon. And since the Nikon is almost 3 years old now, I wouldn't be surprise t see a new version next year.

In real life, using "standard" lenses without tripod, I wonder what is the wise choice.

That's because images are same pixel dimensions

Look at the label on the chart: 500 pixels. The image is shot so that area is 500 pixels wide/high on the sensor for each camera. The Hassy was much farther away.

Because they are shooting the images with the same size per pixel but with a definition of pixel where the SD1 has only 15 million.

Which is exactly why Dave says this test is of "unknown provenance".

But that is pointless, no? By the time you enlarge the SD1 original to match the Hasselblad you're certainly going to end up with the Hasselblad making better images. Okay, it has better per-pixel sharpness, but so what if your resolution is comparatively small?

It is also pointless to compare a small photo of each on a computer screen.

A comparison below of the same scene taken at the same time with a Sigma SD 15 and a Sinar Hy6 with 33 megapixel Bayer back at the same size.

Because people want to believe they can buy a D7000 and get SD-1 quality, and are looking for any justification for that theory.

there are some comparisons to the D3x, a camera similar in both price and purpose, down below in the article. It shows a clear advantage for the D3x.

The authors say so " Data is then taken as kindly mouth cram difference Kyushu Electric Power."
