Sigma SD1

Released September, 2010
  • 15.4 MP
  • APS-C 23.5 x 15.7 mm CMOS
  • 3" LCD
The result is a very conventional camera (in the best possible sense) with twin control dials and direct access buttons for all of the key photographic settings, making it quick and easy to operate with the camera to your eye.

Reviews Word on the street for the Sigma SD1


7.1
Detail resolution and rendition is remarkable, thanks to the lack of an anti-aliasing filter in front of the sensor, and the default colour output is subtle and natural-looking.

8.0
It features a huge 46 megapixel APS-C X3 sensor, dual TRUE II processors, 11 AF cross points, magnesium body with O-ring weather sealing, ISO 100-6400 and a 3 inch screen on the back.

6.0
s .X3F raw files do fare a little better, but currently you can't process these in mainstream software such as Adobe Camera Raw.

Overall

7.0 Out of 10

What People Are Saying Give it to me straight

Sensor

This figure applies across the board for high resolution files, whether you're shooting JPEG, raw or raw+JPEG files.
by TechRadar (Aug, 2012)
We have converted the Raw files using Sigma's Photo Pro 5.0 software 'to taste', and performed some minor tweaking of the resultant TIFF files in Adobe Camera Raw.
by DPReview (Apr, 2012)
We're using Sigma Photo Pro to develop the SD1's RAW files with noise reduction controls set to a minimum, then comparing this to our usual ACR conversions from other cameras.
by DPReview (Apr, 2012)

Raw

All pictures were taken in RAW & JPEG at the finest quality unless stated.
by Photography Blog (Dec, 2011)
Normally we like to compare the supplied Raw conversion software with commonly-used third party Raw converters, most notably Adobe Camera Raw.
by DPReview (Apr, 2012)
If you want to get the best out of the camera, you really need to shoot Raw, and to process Raw you really have to use SPP - there's not really another sensible option.
by DPReview (Apr, 2012)

Iso

In this example, at ISO 100 overexposure by a stop results in clipping of the lightest tones in the chart on the camera's JPEGs, but this data can be recovered accurately from the RAW file.
by DPReview (Apr, 2012)
Image quality quickly deteriorates at higher ISOs though, with unpleasant green and purple colour blotching in the shadows that spoils files at ISO 1600 and higher.
by DPReview (Apr, 2012)
In contrast, at ISO 200 and 2 stops overexposure, the results are essentially identical to overexposing ISO 100 by one stop.
by DPReview (Apr, 2012)

Lens

For almost all of its use the SD1 is a simple photographic tool - perhaps elegantly so, from some shooters' perspectives.
by DPReview (Apr, 2012)
There's also no means of correcting for lens aberrations, despite the camera only accepting Sigma's own lenses (for which the company even supplies correction profiles to Adobe).
by DPReview (Apr, 2012)
The front of the camera is home to a depth-of-field preview button, plus a flash exposure compensation button that needs to be held down as you spin a control dial.
by DPReview (Apr, 2012)

Image quality

Instead the modes differ based mainly on saturation and colour tone, with Landscape being warm and saturated, for example.
by DPReview (Apr, 2012)
Primary colours are punchy but retain realism.
by Photography Blog (Dec, 2011)
More subtle colours are dealt with sympathetically.
