The 18-55 kit lens is marked at 18, 24, 28, 35 and 55mm. Unfortunately, there's no 50mm marking and interpolating on a
non-linear scale is difficult. I'd suggest you mark it yourself by comparison with the 50mm prime.
I think Boris is past these comparisons now, getting ready for the big trip.
Set the camera up with 50mm prime in the house on a tripod and then focus on something like a yardstick and note the
length of the yardstick that's visible. Then install the kit lens and adjust the zoom until you see the same view.
Put a little mark on the focal length scale. You should see the full width of the yard stick (horizontally) at about
6.5 feet.
No, not horizontal. A65 is 3:2 format, A200 4:3 format. to make things the same 'size', measure the vertical. Diagonal
may work, but is a pain to do and leaves both to be cropped slightly. Vertical works.
Taking the A200 is a wise choice. It's a camera you're very familiar with and, most importantly, it provides a
backup. You don't want to go to the trouble and expense of visiting Yosemite only to find that your camera has failed.
Yup
