OK it's not the proper deep test as you might seen it on other pages but it's just the comparison between individual photos that were taken in a really dark room (handheld). Photos are taken with all standard settings inside camera and nothing was done in Photoshop (no sharpening, no color correction,...)... ooh and this time I was shooting JPG's not RAW as usually... One file 9M... so it looks like I need new computer and new external hard-disk too :)
