Nikon D3X versus Sony Alpha 900 – ISO 1600

Using a light level typical for tungsten light shots at 1600 (1/60th at f8 = 1/500th at f2.8 for action, 1/250th at f4 for concerts etc) I have made a quick first day – D3X arrived this afternoon – comparison which, in the process, also evaluates two lenses (24-120mm VR Nikkor and 28-105mm RS Minolta) and two anti-shake systems. Sadly, my 5DMkII test kit went back on the same City Link van which brought the Nikon kit. Look out for my Nikon review/s in the British Journal of Photography soon.

There are caption notes to each image. The point of targeted focus was the end of the fingerboard with the spattered rosin on it. Feel free to download and print. The red rosin cloth is interesting, so is the sharpness of the point of focus. Clicking on the small images here will open a full size 24 megapixel file in each case!

Ref the exposure difference: these were locked down manual exposures. The Sony does not appear to achieve a true ISO 1600. However, when shooting the same subject using auto exposure, the Sony image is perfectly exposed and the Nikon consistently overexposes. Here, I have set the exposure to the correct density for the Nikon.

    Who cares? Megapixels stopped being important 12 megapixels ago. Sensor size is even questionable in terms of quality improvement over APS. The real issue should be on light-gathering and focus. Nikon, Canon, and Sony should all be focusing on these elements instead of engaging in a phallically illogical battle to increase pixels. It’s gotten to the point where the only way we can critique one camera from another is if we purposely take photos in horrible lighting conditions and then put them under a microscope to examine their “shortcomings.” Give me a break…give us all a break…
