This photo, taken back in December, shows you how large it is; you're still only seeing a small part of it here.
Meantime, I managed to snap at least 75 photos as I walked. Since my auto-focus has failed, I was focusing manually, and I was really quite pleased with myself. I knew some of them would be blurry, but I thought I was doing fairly well. Then I loaded them up on the computer screen, and realized what a disaster my focusing efforts had been! They were virtually all too blurry to use. I deleted about 65 of the 75! Needless to say, my malfunctioning lens has now gone to the camera hospital to see if it's worth repairing. I'll be using my iphone camera or our little point-and-shoot for the next 2 or 3 weeks. At least I did have a good walk!
