Forgot mention in another critical area - DR. I found my 60D is vulnerable in highlight clipping (in addition to shadow grains/noises). Even old 5Dc is still noticeable better in this regard. I need to recover highlight in many my 60D photos to 100% in LR but only 20% in 5D series cameras.

That might be a better topic for processing or shooting technique and unrelated to this discussion. Here it seems more off topic.

Based on my experiences of processing 35k+ 5D photos and 20K+ 60D photos. This is the area (highlight clipping) that 5D series even old 5Dc still much better and Nikon DX is probably also better.

From respective DPR lab test that is based on JPEG engine. With RAW, FF 6D will have more room to process.

I know DR is not directly related to OP but a key factor (especially highlight clipping) in IQ spectrum.

Here is my comparison when I coincidently have two shots in the same room but in different time. I didn't adjust AWB and I agreed 60D has better AWB by default but it's very easy to adjust.


60D+Sigma 17-50/2.8 OS

5D raw in LR3

60D raw

The reason I gave 5D files -1/3 EC is well known that 5D has +1/3 EV more sensitivity than standard ISOs. So its ISO 1600 actually is ISO 2000. So I always leave -1/3 EC permanently in 5D.

Anyway as I said my #1 adjustment in 60D files is highlight clipping.

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
