The usual complaint is that the Earth is HUGE, so in the photos it should be HUGE but it's TINY. I'm guessing here that the complaint is that in one of them the Earth is TINY, but in the other it is HUGE - OMG!!!
My stock response is for them to go out and take a photo of the moon and report back on how big it looks in the image. In this case they would obviously need to take two different photos, and as they never manage to take one they would never manage to take another one on a different 'zoom'. They must wonder what kind of devil worship is occurring when they see people change lenses.
Why oh why didn't Father Ted cover this one as well as 'Small, far away"...?
