Just because you don't need the MP's, doesn't mean it's not helpful to others.


Agreed. When I went from 10mp to 18mp (40D to 60D) two years ago I realized how significant the the difference in MP was....

Even so from Canon s95 to RX100 (10 to 20mp).

More than have the ability to crop harder, I also like to zoom in and study details on my 27" computer screen, but thats just me.

I have a question related to this. I am still using my 40D together with 3 Tokinas 11-16mm, 16-50mm and 50-135mm all f2.8. For macro I am using the Canon 60 mm f2.8. Although the 40D is a very good camera I was always under the impression that I could get more out of the glass. How will the change from 10 MP to 20 MP affect the image quality? Your guidance is appreciated.

Thanks, Eric


It depends the uses of your photography and whether image quality is important for you.  More and more photography is limited to posting online.  The typical online image uses less than the equivalent of 0.3 mp.  For many photographers, even the current cellphones provide way more resolution than is needed.

If you print or crop, then resolution becomes more important.  Even then it depends on the types of images you print.  Typically a portrait does not need to be high resolution.  In fact high res could be a disadvantage and will emphasize skin pores and flaws.  High res becomes important if you are shoot landscapes or other images where detail is important.

I suppose fewer and fewer of us are interested in improved image quality.  That is why Canon can sell WiFi and touchscreens and video performance instead of IQ improvements.

Anyway, you will clearly see an improvement in IQ when moving from 10 to 20 mp.  Don't expect to be able to print twice as large.  You need 4x the increase in order to do that.
