Leica M4 Specifications Leica M4 I like the original Leica M4.  With its brass gears, his is one of the smoothest working Leica cameras I have ever used.  All other M4-P & M4-2 used steal gears to facilitate use with Leica motors.  The smoothness and build quality of the original Leica M4 is legendary.  The M4 when used with the 28mm or Tri-Elmar will only bring up framelines for the 135mm.  If you use the border of the viewfinder itself, you will have the perfect framelines for the 28mm, making the 28mm or Tri-Elmar lens perfectly useable with the M4. 1967-1975 SN# 1,175,001 1,443,170 Finish Chrome, Black, Black Paint Lens Bayonet Mount Shutter Focal Plane Film Advance Single Stroke Lever Rangefinder/Viewfinder Coupled Frames 35,50,90,135 Rangefinder Base Length 48.5mm Viewfinder Magnification .72 Field Selector Lever Yes Shutter Speeds 1,B,1/1000 Flash Sync Yes, Elec. 1/50, Bulb 1/500 Exposure Meter No Film Speed Self Timer Yes Weight 600 Grams Leica M4-2 1977-1980 SN# 1,468,001 1,533,350 Finish Chrome, Black Lens Bayonet Mount Shutter Focal Plane Film Advance Single Stroke Lever Rangefinder/Viewfinder Coupled Frames 35,50,90,135 Rangefinder Base Length 48.5mm Viewfinder Magnification .72 Field Selector Lever Yes Shutter Speeds 1,B,1/1000 Flash Sync Yes, 1/60 Hot Shoe Added Exposure Meter No Film Speed Self Timer No Weight 525 Grams Leica M4-P Leica M4-P 'Mt.
