I have had my 40D Since Focus on Imaging and have taken about 11000 pictures (yes really), I use mostly Sigma EX lenses (apart from a Canon Nifty Fifty). What I have noticed is that the sharpness is not as good as I would like it.
I have been trawling around many web sites and come up with 2 different reasons for this:
1 - There have been some issues with the Electronics in which following sending back to Canon for investigation and fixing have made little if no difference.
2 - The 40D automatically puts an anti alias setting on all images irrespective of whether shot in Raw or Jpeg.
Scenario 2 has been confirmed by Canon (according to the web site i looked at) and they advise using unsharp mask with the following settings:
Amount 300%
Radius .3
Threshold 0
But stipulate images may differ. I have used the above settings and can say that doing this makes a huge difference.
I have to say I would prefer that if this anti aliasing situation was true that it could be changed.
Does anyone else suffer from soft focus on the 40D and what are your thoughts on scenario 2 (assuming it is true)
