It is not just the lens, it is the curvature of the moon. The US picture is definitely more curved, expressing a far larger area than the Russian
photo. The Russian lens simply focuses on a smaller area and brings it in.
The perspective is no different when measured by that.

did a quick photochop and im going to have to agree....
looks like its just zoomed in

Actually, both the U.S.A. and the Russian photos of the Earth, taken from the Moon, are grossly inexact in size due to the lens used on the cameras
that took the photos, as opposed to what an individual, actually standing on the Moon and observing the Earth through only his eyes, would see.
In that case, the actual size of the Earth would appear to the individual standing on the Moon to be .59O inches (15MM) in diameter. To better
illustrate it, if you cut out a circle on piece of paper to that diameter and stuck it to your monitor screen, simulating looking through a window on
the Moon, it would represent the actual size of Earth as you would see it.
Conversely, and using the same scenario, if you were on Earth and were observing the Moon, it would appear to be only .162 inches (4.1MM) in diameter
on your 'window'.
Here's a simple way to get a good idea, or to visualize, what a satellite, like the Moon, would like in space. Hold a pellet-gun BB, .177 inches
(4.5MM) in diameter against your screen. That would represent the size of the Moon as seen by astronauts viewing it, without a camera, from the front
window of their spacecraft at a distance of 220,000 miles from it.

Okay, I've just been looking at the lastest LASCO C2 shot and I noticed something interesting. The sun's disk is blotted out with the little
circular thing, but you can still see flares and prominences and whatever else. You can also see stars in the background.

Isn't it interesting that in the background of a shot of a star, you can still see thousands of other stars, but in the background pictures of our
moon taken by NASA and other space agencies, a body lit only by reflected light, you don't even see one star?
