OK, to keep you all up to date, Sigma have announced a new firmware update for the camera, Ver.1.01, which has been loaded onto the test camera prior to these colour/noise checks.

 

The firmware upgrade is simple to do and takes around 2 ½ minutes to complete on the camera once the CF card with the new downloaded soft is loaded into it. Just make sure that a fully charged battery is used if you don’t have the mains adaptor (which I don’t) and you should have no problems.

..whereas this bright Mustang with a similar sky under-exposed by about a stop! The compenstion settings should have been used here!
I’m sure you will all be familiar with the GreytagMacbeth™ Colorchecker® chart. What I have done is to take images of this chart and run them, in this instance, through Norman Koran’s Colorcheck, part of the Imatest®Pro software Suite. This analyses colour response as well as noise. All the actual result charts will be made available in a downloadable .pdf document once I have finished the testing for anyone who is interested in the Geeky stuff.

  For this first toe-dip though, here are the image crops of the chart which, when clicked on will open at actual size.

This set of images have been taken with the camera set to Fine Jpeg at the native resolution. The lens used is the 18-50mm f/2.8 EX DC Macro set at 38mm and f/5.6

 

The camera was set to Aperture priority with the WB set to Auto. 8 Segment metering mode used.

 

ISO100
At ISO100, we all know the Foveon Sensor is a superb tool!
As you will see from some of the result charts, the exposure varied by approx 1/3 rd stop as the camera was taken through the ISO range from 100 to 800 ISO. This type of variation is quite common with all cameras.

 I’ll leave you to study the images and go off and do the same thing in X3F (RAW) mode and run the results through SPP 3.0 to see if there is a significant difference.

ISO 200
At ISO 200, things are still pretty good.

 

 

 

 

 

 

 

 

ISO 400
Still very usable at ISO400
