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:
I do not like the lens hood design – it’s using a screw to tighten the lens hood (hopefully one day Voigtlander will refresh this lens hood design):
Here is what you get with the lens: lens hood (reversible), lens cap and a rear cap:
This is the “Classic” (usually a code word for “low contrast”) lens design of the Voigtlander Heliar 75mm f/1.8 VM lens:
The weight (15 oz/427 g) of the Voigtlander Heliar 75mm f/1.8 VM lens is almost identical to the weight of the $3,795 Leica Summicron M 75mm f/2 lens (15.2 oz/430 g). Here is a quick size comparison between the Voigtlander 75mm f/1.8 VM, the Leica Summicron 90mm f/2 ASPH and the Iberit 75mm f/2.4 (sorry, I do not own the 75mm Summicron):
Next is a picture of the lens obstruction in the viewfinder of a Leica M10 camera:
The Voigtlander Heliar 75mm f/1.8 VM lens has 6 elements in 3 groups Heliar optical design which provides very sharp and color accurate images. The aperture is made out of 10 blades for a smooth bokeh. The minimum focusing distance is 0.9m/3ft. Here are the rest of the specs:
| Focal Length | 75 mm |
| Aperture Ratio | 1:1,8 |
| Minimum Aperture | F 16 |
| Lens Construction | 6 elements in 3 groups |
| Angle of View | 33,2° |
| Aperture Blades | 10 |
| Minimum Focus | 0,9 m |
| Maximum Diameter | 57,9 mm |
| Length | 73,8 mm |
| Mount | M-Bajonett (VM) |
| Weight | 427 g |
| Filter Size | 52 mm |
| Color | black |
| Others | reversible lens hood |
Those are two 100% crops from images taken with the Voigtlander Heliar 75mm f/1.8 VM lens on a Leica M10 camera:
Some vignetting can be seen at f/1.8 and it is almost gone at f/2.8 (lens detection/correction off):
Barrel distortion is practically non-existent. I didn’t notice any lens flare:
Some purple fringing is noticeable (top left corner):
