The Voigtlander is a MF lens. At 20mm on a canon crop you get a field of view of 20 * 1.6 = 32mm.
- Very small size - great for street photos and places you do not want to stand out
- At f/5.6 IQ is razor sharp
- Colors and general IQ is superb at f/5.6
- Build quality is superb - MF ring is very solid
- MF can be dicey
- Soft at f/3.5 - f/5
- Focus confirm "beep" is dicey
This little gem of a lens is not for low light or indoor photography. Nor is it for anything moving as it is MF.
But take it outside to a colorful scene, be it foliage, landscape, buildings, or anything with nice light shape and color - and WOW. You set the distance scale to infinity, and the f-stop to f/5.6, and shoot away at anything opx more then 5 meters away.
The images are crisp,sharp, and contain a unique color retention.
I used it for some street photography - and its small size and light weight makes it perfect.
As someone who likes primes, and uses a canon crop, there is not much out there as far as wide primes.
The Zeiss 21mm is very heavy and expensive. The canon 20mm is poorly reviewed. I found this little gem to be my compromise.
If you want to focus in on something closer then 4-5 meters, you will need to manually focus with LV (not so bad) however this eats up the battery.
