We often get discussions about the best camera for landscape, lowlight, action and portraits but which camera would produce the best results for macro, using say the Canon 100mm macro and the Canon 65mm 1-5X macro?

is it just a matter of resolution i.e. the total number of pixels or is low light ability important? I am particularly thinking of insect photography.

Possible cameras might be 5D ll, 5D lll, 6D, 7D or 60D.

APS-C magnifies more. If you have an 1:1 lens, APS-C (due to its smaller sensor) will magnify 1.6x more.

This isn't true. Magnification refers only to the size of the image of an object relative to the actual object. This doesn't change with sensor format; the image of a bug at 1:1 will be the same size as the bug, regardless of the amount of sensor surrounding it.

Where full frame will allow a 36mm wide subject to fill the frame, APS-C will allow a 22mm wide subject to fill the frame.

Correct, and very useful, but not magnification. Filling the frame has nothing to do with magnification, it just defines ​how much​ of the subject will be captured at any given magnification. That's useful in the same way that the longer equivalent focal length of a crop is always useful -- to help isolate the subject, etc. But that's different from magnification.

And if the sensor has a higher pixel density -- as crop cameras often do -- then the image may be more enlargeable without loss of detail. That also gives a potential advantage to using a crop for macro.

Great pictures, by the way. I hated to delete them!
