Tamron SP LD 28-105mm f2.8 for Canon EF lens mount_Leica Thread Mount and shutter speeds are goodThe Tamron SP LD 28 105mm f2. 8 is a fast zoom lens for Canon EF mount cameras. Goes from 28mm wide angle all the way up to 105mm at a consistent f2. 8, and while it's relatively stout, it's still pretty easy to handle. Has some minor cosmetic wear on the barrel; diaphragm blades are clean and focus is smooth. There is a minor amount of dust, but no haze or fungus.
