But do you have any doubt that HCB would have used the modern Leica lenses if they had been available to him 50 years ago? One of the main attractions of today's Leica lenses is precisely the fact that they deliver outstanding image quality even at maximum aperture. You are the one who has educated me and the rest of the LUG on this very point! It allows me to use slow films like Fuji Velvia or Provia 100 or KM25/64 and get sharpness, gradation and colour rendition undreamed of just 20 years ago. So, the bar has been raised higher and our standards are higher today than in the 40s or 50s. I am of course not saying that our artistic standards are correspondingly higher, but Leica has spoiled us and gotten us used to the idea that you can achieve incredible image quality at f1.4 or f2. > In my view the demand for f/2 lenses and wider, even in the > classical M picture environment is a bit exaggerated.

The fastest lens I own for my R system is the 2.8/60mm Macro Elmarit. I just bought the 4/35-70mm Vario Elmar to go with my R8. But when I shoot with my Ms, it is a different story. I paid a lot of money for my 90mm Apo Summicron and the 135mm Apo Telyt (and of course my Noctilux), with the express purpose of using the wide apertures. Of course, the easy solution is to buy the Tri-Elmar *in addition* to the other lenses, but before I do that, my Baan stock would have to appreciate a lot more ;-) Kind regards, Nathan - -- Nathan Wajsman Overijse, Belgium General photo site: http://belgiangator.tripod.com/ Belgium photo site: http://members.xoom.com/wajsman/ Motorcycle site: http://www.geocities.com/MotorCity/Downs/1704/
