next PZ lens test report: Pentax SMC DA 35mm f/2.4 AL
#50
While I have not used a 5D2 myself, I'm making an assumption the sensor technology is similar or same as the 50D which came out around the same time. Based on DxO mark results, the noise score differences between the 50D and 5D2 are about what you would expect if you scaled the same sensor design. Having said that, the 7D is... about 1.2x better per area, which if I'm calculating right, is just over half a stop.



The 50D did exhibit some visible banding under specific conditions. On that, shadow areas can show banding if you bought them up. At low ISO, it was a non-issue unless you're doing a ridiculous amount of shadow recovery, such as extremely under-exposed shots or attempting single file HDR. To me banding wasn't really significant until around ISO3200, where relatively minor shadow recovery (or similar exposure adjustment) started to have an increased chance of showing banding effects. The 18MP sensor replacing that doesn't show banding in similar conditions, although if you keep digging deep enough you can still find some if you really want.



On the user set auto-ISO limits, I'd expect that to be present in the 5D3 as it has started appearing on lower level Canon bodies now.
