Hi guys,
I made the upgrade from the 5d to the 5d2 and it seems to me that the file requires different sharpening values due to the AA filter.
The 5d is sharp at pixel level so I typically leave sharpening value between default 25 up till 30. However I seem to be cranking it up to 50 on the 5d2.

What values are most of you guys using?


5D Mark II | 5Dc |17-40 | 24-105 | 70-200 F2.8 IS | Sigma 50mm 1.4 | 580EX

If you are asking about capture sharpening, what software are you using for raw conversion? I don't think that there is any difference if using DPP. With ACR/LR, I haven't found much variation between camera models nor brands. The thing that seems to be the most relevant factor is the subject.

Remember also that when looking at 100% crops, you are looking at different magnifications of the image projected by the lens so part of what you are seeing is the limitation of the lens sharpness. Also consider that when viewing at 1:1 image pixel to screen pixel, a sensor with a lower density of photodiodes will appear sharper compared to a sensor with a higher photodiode density. The other side of that coin is that the higher density will reveal greater image detail.

I presume that you have already tweaked the micro-focus adjustments for your lenses.

DPP changes the default values automatically. I have found the same to be true when using LR4.1 for RAW conversions. The 5D looked good with 25-30, and 5D3 I have works better with 35-45. I also typically turn up the masking do around 85 to get mainly edge sharpening and set the radius to 1.1.

also don't forget to do the output sharpening when exporting to jpeg

My typical capture sharpen values in ACR are: Amount = 40 - 50, Radius = 0.7, Detail = 15 - 20, and Masking = 25 - 50. Anything above about 60 on the amount start to very noticeably show artifacts (crunchiness). I Keep the radius value small since this is capture sharpening only and not sharpening for effect. Edge halos are likely to become too evident if the radius is greater than about 1.2. The Detail and Masking functions work together -- detail emphasizes edges, but creates global noise in the process (noise tends to increase rapidly for values over about 25) while masking restricts where the detail sharpening is applied. For those who may not know, you get a much better idea of what is going on when applying sharpening if you hold down the ALT (Option) key while adjusting these sliders. This should be done at 100% or greater magnification. I have used these guidelines for capture sharpening on images from several Canon and Nikon models.

Capture sharpening is not the place to try to compensate for missed focus. The best compensation for missed focus is making the image smaller.
