Fun for me to go back and re-read stuff from a while back...
Another image that convinced me the time had arrived to re-appraise one inch sensor cameras. It's a "lab test."

I'm pretty sure I'm going overboard with all this "one inch" enthusiasm but please know that I'm not rushing to abandon all other formats or denigrate their use as great imaging tools for photography. I guess I'm sharing this succession of images and stories from my experiences shooting smaller format cameras on real jobs because I am personally so amazed at how well they work in lots of different situations. I believe that the smaller format cameras are important tools to have along on most projects and offer an ease of shooting that, in many cases, is unparalleled.
We all have a prejudice, based on digital camera history, that tells us that all big sensor cameras make better images than all smaller sensor cameras. If you are just measuring noise response at higher ISOs you'd be more or less correct but there is so much more that goes into the success of an image and a lot of it has nothing to do with the noise formula. Even in that arena the one inch sensor cameras I am currently using outperform the noise characteristics of even full frame camera from only a few years ago. I have only to pull up images from the Sony a850, a900 or Canon 1DS mk3 to know that this is true. So, here we are five years down the road from the introduction of the full frame
