Leica M10 lens report: Voigtlander Heliar 75mm f/1.8 VM lens
General


The Voigtlander Heliar 75mm f/1.8 VM lens ($699) is a good choice for portrait and general people photography as well as low light photography (see the sample photos further down in this post). No matter how experienced you are with a rangefinder camera, manually focusing at 75mm f/1.8 M lens is not an easy task and I highly recommend using a viewfinder magnifier (I do not own one and I did have many photos where I missed the focus when shooting the lens wide open). The total depth of field of a 75mm f/1.8 lens wide open at 10m/32ft is almost 2m/6.5ft. Compare this to the 1.5m/5ft depth of field of a 90mm f/2 lens and you may see another advantage of using 75mm focal length instead of 90mm on a rangefinder. Here is a picture of the focusing scale – you can see that the difference between f/1.9 and f/16 is just a few millimeters:
