I was out shooting yesterday. I had my 5DII and my 7D. It was a sunny and the scenes had plenty of bright highlights. I really struggled with the 7D. Shooting in AV I had to go to -1 1/3 and I stll need to use the full latitude of recovery and highlight recovery from the RAW in post.
The lighting conditions were quite challenging but the 5DII managed well. It just seems to be able to handle a higher dynamic range. Is that a pixel pitch thing? Are there really too many pixels on the 7D's crop sensor to do a good job?
Have others found the same? |

| Interesting result in their tests: ISO 50 and ISO 100 are actually both ISO 73 on the 5D Mark II. There's no difference between ISO 100 and 200 on the 50D either. |

| What still never ceases to amaze is just how far we've come in less than 10 years. But to the original question, yes, I think the pixel pitch is a big factor here. What's important is the "full well capacity," basically the number of electrons that can be held in a given pixel location. The physically bigger the cell, the more electrons it holds, other things being equal. Doubling the pixel pitch means *four times* the area, so the full well capacity scales with the second power of the pitch. |
