Contax G Lenses for LEICA M 26 February 2009 . When it reads one time, the actual time may be one-quarter stop faster or slower. In five years, you'll be thanking me.A 90mm f/1.4 would have been too fat for the camera's rangefinder and viewfinder to see through, so the focal length had to be shrunk to 75mm so that LEICA could offer an f/1.4 tele like everyone else.The 50mm lens is ideal for photographing one subject at a time. LEICA conveniently illustrates their M7 promotional literature showing the 50/75mm finder display, which is the only one for which the LEDs aren't in the finder's picture area.I live on the edge, so I now close it all up, set the shutter to 1/1,000 if I'm in dim light, and only wind past the first frame.0.72x with frame lines for 28/90mm, 35/135mm and 50/75mm lenses.Unfortunately the long exposure (32s) meter only reads in Auto mode. Once the display turns off after 16 minutes, you can leave the M7's shutter open all year; it only needs battery power again to close the shutter at the end of your exposure.The only other sound is the manual winding of the film, which has no ratcheting on advance, and only a little on rebound.Towards the end of the travel, the resistance increases a second time, after which the shutter releases.The shutter is electronically controlled in Auto and manual, although manual speeds of 1/60 and 1/125 (only) are mechanically controlled. Eyepiece corrected for -0.5 diopter. With a 50mm lens and 81A filter, it reads 1/6 (almost 1/8) at f/2.The LEICA M7 is easy to use and shoot. Video games, digital SLRs and cell phones all have rechargeable batteries that you hope last as long as a week between charges, and once the battery dies, the item is useless.The rangefinder has been improved in current production, and the original poorly designed electrical DX readout has been replaced with an optical infra-red LED DX readout. Correction lenses from -3 to +3 diopters are available. With LEICA, the quality is enjoyed long after the price has been forgotten. Really only rated as low as 4 seconds at ISO 100, but it reads and to 32 seconds while lighting an "out of range" arrow in protest.Here is a table of how my M7 reads at room temperature at ISO 500. If you've forgotten, you can cheat by locking exposure, covering the lens with your hand, releasing the shutter, and then taking your hand away fast.I get sloppy results with my 28mm lens at all distances. I had a chance to use the Leica M7 TTL.72 rangefinder film camera together with the Leica 35mm f/2.0 Summicron M Aspherical lens for about a month and shot with this gear in different conditions and shoots.
