  • Sony Alpha 900 and Nikon D3X raw file noise comparison

    Like Mike Johnston writing in The On-Line Photographer, I’m aware that any attempt to line up one or more cameras and show comparison images or make judgements is on to a loser from the start. And any webmaster who puts an external link in the first half dozen words of a new post is losing the plot too! But here, for what it’s worth, is the first line-up of results processed using the same software from A900 and D3X uncompressed raw files converted without sharpening or noise reduction.

  • Studio comparison A900, 5DMkII, D3X

    This set of full size shots was taken with the still life left set up, because the Nikon and Canon cameras were not here at the same time. It compares the A900, 5DMkII and D3X using the converters supplied by the makers – Image Data Converter SR2, Digital Photo Professional, and Capture NX2. Each small image in the article can be clicked to open a Level 10 quality full size JPEG – beware, the largest is over 13MB of data.

  • 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.

  • Alpha 900 – finder and frames

    It’s not going to be long before we see the Alpha 900, and some cameras are known to be out there on trial in the hands of Sony staff and pre-release testers. I am not one, so rest assured, this is not a leak! What can you expect from the Alpha 900’s full-frame prism finder?

    (Note: this post was written in early August – it is now 100% certain that the finder is 100%, and at 0.74X magnification will be – as had been hinted – the largest of all current DSLR finders in apparent visual terms except the EOS 1Ds Mk III which is 0.76X. Comparisons: EOS 5D 0.68X, Nikon D3 0.70X)
