Frame size vs magnification
As an amateur / semi-professional photographer of the better part of a decade, I understand the difference between focal length and crop factor. Though the FOV is the same, there is a significant difference between a photo taken with a full frame DSLR using a 50mm lens and one taken with a crop sensor DSLR using a 35mm lens. I absolutely understand the difference.
However.
I have two full frame DSLRs and one crop sensor. They're all 24 megapixels.
When using a telescope focused to infinity, surely the difference between the two is literally exactly the same as increasing the magnification..? I keep having people insist upon me that they're not the same thing. I contend that with these cameras having the same resolution but different size sensors they are EXACTLY the same as increased magnification.
Please explain why I'm wrong!
