Do you look at DxO mark and scope out the MTF charts and get all tied up about what camera is the best camera and what lens is the sharpest in the world?

Well Ashfaq Kahn was looking at DxO Mark and this is what he asked me.

Ashfaq says:

Dxomark gives an overall score of 20 and sharpness of 14 pmix to sigma 17-50 f2.8 os hsm lens when used on d7100 but provides an overall score of only 17 and sharpness of only 10 pmix when used on d7000 even though d7000 has bigger photosites than its counterpart .

Is it the megapixel count in a sensor that increases the overall score and sharpness of a lens and if it is then why there is a difference of only 1 point in overall score of d800 and d610 when used with nikon 24-70 f2.8 . D800 scores 28 and has sharpness of 15 and D610 scores 27 and has sharpness of 15 when used with nikon 24-70 f2.8, even though D800 is a 36 megapixel camera compared to 24 megapixels of d610.

Can Dxomark be trusted and is it relevant?

In short? I don’t care about DxO mark, or MTF charts, or any of that overly technical crap.

Sure, it has it’s place, but these days it’s hard to buy a bad camera or a bad lens, so just buy a camera and lens already and then get out there and take some damn photos!

Your camera is an amazing tool, but it’s no good to you if you don’t know how to use it!
