g-man1 Posted August 27, 2005 Share Posted August 27, 2005 What is the shutter lag in milliseconds of the Leica CM? (As separatefrom focus delay/lag). Link to comment Share on other sites More sharing options...
e_b7 Posted August 27, 2005 Share Posted August 27, 2005 I'd like to know that too. I have a CM, and have used it successfully in candid people shots. There is a very slight delay. You can't sieze the moment as with an M, but it's very close, almost to the point of being negligible Link to comment Share on other sites More sharing options...
malcolm_tentt Posted August 27, 2005 Share Posted August 27, 2005 0,1674612 milliseconds. I've a cracking good clock in my loo. Link to comment Share on other sites More sharing options...
g-man1 Posted August 29, 2005 Author Share Posted August 29, 2005 Leica responded to my question: CM: 803,20 milli-sec (AF) CM: 465,20 milli-sec (MF) BTW, Leica M7 shutter lag is 18ms (or 24?) Link to comment Share on other sites More sharing options...
carson wilson Posted September 3, 2005 Share Posted September 3, 2005 Using a video camera capturing approximately 30 frames per second (29.97 fps), and confirmed by the digital timer on my Palm T3 in the same video frames, I've observed the following: Measurement 1. For a Leica CM set to autofocus and prefocused (shutter button depressed half way), the interval between the time the shutter button starts to travel from half way to fully depressed and the time the shutter is fully open at F4 is 12 frames. 12/30 frames = .4 seconds. Measurement 2. For a Leica CM set to autofocus and prefocused (shutter button depressed half way), the interval between the time the shutter button has become fully depressed and the time the shutter is fully open at F4 is 5 frames. 5/30 frames = .16 seconds. So, if you prefocus it takes 40% longer to move the shutter release from half way to fully depressed than it takes for the shutter to open afterwards. For comparison, here are similar measurements for an Olympus Stylus Zoom 70: Measurement 1. 16 frames or .53 seconds; Measurement 2. 7 frames or .23 seconds; Similar measurements for a Leica CL: Measurement 1. 3 frames or .1 seconds; Measurement 2. less than one frame or under .03 seconds.

g-man1 Posted September 6, 2005 Author Share Posted September 6, 2005 Good stuff! Now, if you don't mind testing the Contax T2 and stylus epic.... Since posting, I took photos with my M7, T2 and stylus epic at the moment my stop watch hit ten seconds and got 10:24, 10:66, and 10:45, respectively. This suggested that I had an biologic shutter lag (the time between my eyes seeing the moment -- or brain anticipating the moment -- to the time the film captures the scene) was about 222 ms. :-) Link to comment Share on other sites More sharing options...
