Interesting Bookmark I found today...

I bought a used book on film developing and this was in it; apparently used as a bookmark...

Thought it was interesting.

Well done display showing the relative view angles for the 4 most popular lenses. The 35mm, of course, needed the goggles to change the magnification in the M3's finder because the largest frame was for 50mm. For many years, I used the generation 1 35mm f/2.0 Summicron with goggles, the famous 8-element version. Some people still like that 8-element version more than more recent ones. It was a spectacular performer, a jewel of craftsmanship.

It shows and proves how good this stuff used to be in the OGD. Now photo world is taken over by the self pro-claimed "masters" like Scott Kelby and the likes.
