PHOTOOG Photography writings by Olivier Giroux


Neat Photokina Blog

Some of the best chronicles of this Photokina 2008 are in David Farkas' blog, over at

If you only have time to read only one of his posts, I would read this one where he recounts a very intersting discussion with Peter Karbe (the Canadian in charge of Leica's optical program for the past few decades). He reveals tasty morcels left and right, but my favorite is the one where he let slip that the 50mm Summilux-M ASPH is an APO design, had been from the start. They never advertised it publicly because they felt it would sound weird for a 50mm to be labeled APO, so they only advertised it on its sister lens the 75mm Summicron-M ASPH.

Notice the different shade of glass elements, indicating different glass chemistry. Click to enlarge. Linked from here.

In another article I found a really neat discovery. Not only did Zeiss display a cut-out 2/100 Makro-Planar T* lens, that's super cool, but that lens was a relative of mine too. The very same person verified its assembly and test.

This isn't all there is on David's blog, so go check it out.

[Apparently David got his trip paid for by his employer store. I'm not saying I endorse the store, but it looks like a good place to get high-end boutique stuff.]
