I suspect much of the magic of the shot lies in the silent message this woman is sending to me; "I clearly see that you're pointing your stupid camera at me. I despise you for harassing innocent people with your lack of respect, however, my attitude is to neglect you." A while ago someone in a B&H review described the Apo Telyt as "ridiculously sharp". I agree; it is really a very sharp lens. Some weeks later, though, I read what JT wrote about the Apo Sonnar, and became curious. Then, last month, I stumbled over one in mint condition, at a very reasonable "used" price in a serious pro photo shop. I decided to sacrifice a Elmarit 24/2,8 ASPH, a wonderful lens which I bought new almost 20 years ago, but which for me fell between my Lux 21 and Cron 28. So, I traded. And - I'm still in a state of severe shock. The Apo Sonnar cannot be described; it has to be experienced. The issue where Leica lenses are unbeatable is size and weight; this monster must be near three times the weight of the tiny, elegant Telyt, and I will not be able to sell the Telyt, BUT . . I simply have to solve this problem somehow . . possibly by pushups . . which may prove a bit late at my age. I took the Sonnar to a concert last night, very low light level; I would have been dead with 3,4 (Telyt) - I will post a couple of samples!
