Hi there
First two questions:
Whats the difference between choosing Ekos->CCD->CanonDSLR & GphotoCCD?
Whats the difference between Pixel size (µm) and Pixel size X/Y input under image info?
My Canon has 4.3µm pixel pitch so I have to enter 4.3 in this 3 fields?
I have a Canon 700D. It's default RAW (cr2) image dimension is 5184 x 3456. If I take raw/fits captures from ekos I always get 5208 x 3476 images no matter what I set in the image info tab. Is this known or maybe an upstream bug? When I set image settings to native I get correct sized images.

pls excuse my bad english!
1. Same driver, no difference. For new users CanonDSLR is more intuitive that's all.
2. It should be all the same unless you have a non-square pixel.
3. I'll investigate that, sometimes dcraw returns bogus results especially on RPi.
ok thanx for the info
To be shure the resolusion issue is not limited by a missconfigured system I set up another linux box with latest Ubuntu.
Same happens there. If I open any *.cr2 file with ufraw,darktable.. I always get 5208 x 3476 pixels. When I look at it in dcraw
it shows thumb size correctly, but I guess the thumb was not generated by dcraw.
PS. I have no RPi, all systems are x64

pls excuse my bad english!

5208x3476 is the correct decoded size. I tested with my 40D and I also got a different size when I viewed the CR2 but when I opened it in PixInsight and other programs I got the same size as reported by Ekos, the full "output size" as reported by dcraw.
