Has anyone attended this workshop? I am signed up for one in Los Angeles this coming weekend and am quite excited about it. Naturally I am having a great time pulling out my hair trying to settle glass, but I have committed to carrying only one extra lens and the usual cards and batteries, all in jacket pockets, with no camera bag. So here is my dilemma for glass on the M Monochrom (no color from me this weekend). On the body will be either the 35mm f/2.5 Summarit-M or one of my 50mm lenses (50mm f/2 Summicron v5, 50mm f/1.5 C Sonnar, 5cm f/1.5 Jupiter 3 or 5cm f/1.5Carl Zeiss Jena Sonnar). If I go with the 35mm, I'll carry the 90mm f/2.5 Summarit in the jacket pocket. If I go with a 50mm, I'll bring either the 35 Summarit or give another go at 24mm with the 24mm f/3.8 Elmar-M ASPH that I just put up for sale. The workshop will be mostly street and urban photography in downtown Los Angeles, with a good amount of night photography on Friday. Saturday will be out on the streets most of the day, and I expect to get a lot of use out of my ND and yellow, orange and red filters. Sunday is mostly in the classroom doing post and then exhibit/critique of best images. In addition to my own gear, I can borrow almost any current Leica lens or body, though I prefer not to play with anything I can't afford to buy, lest I not get too spoiled and frustrated. Thoughts? Advise?
