Re: Cut the theory, try it out for real

It could be a learning opportunity for both of you.

Take both cameras and use the same ISO and aperture settings at
200mm. If in 'A' mode, the shutter speed may vary between the two of
you to make up any difference in metering. That's fine.

Shoot some agreed upon object, such as a rock feature or a distant
tree or building. Your friend's camera will appear to be zoomed way
wide compared to yours, so you'll have to agree on where to place the
object in the frame. I'd suggest that both of you center on the exact
same point.

Go home — and let him do his digital zooming-in on his images so they
equal your field of view. He may be confounded when he sees that your
image is a 4:3 ratio and his is 3:2. He can deal with it, but some
fat will have to be trimmed from somebody's photo. If you agree on
doing 8x10 prints, he'll be trimming even more fat from his. (Don't
agree to 4x6! That's not big enough for comparison anyway.)

Once complete, do a side by side viewing of the photos and see how
his theory bears out. If your camera wins, he may next be convinced
that your 50-200 is just a better lens.

I'd like to see the results!

Perfect answer! Let us all know how it works out for you!
