The 28mm M-Hexanon, like the its focal length, occupies a strange space that is neither here nor there. I have never had good luck with 28mm lenses, if only because the angle is a little wide to be comfortable for close shots of people and a little narrow for some of the landscapes I shoot.
Only on the verge of selling mine (for lack of use since way back when I had an M8) did I shoot a bunch of tests with an M typ 240. This particular lens had been recollimated to be at exactly Leica spec (most lenses made before the M8 were not set up to hit the center of a flat sensor).
This piece will not editorialize much but instead show it like it is. Which is quite good, far better than I had remembered.
First, the obligatory “how sharp at a meter” exercise. This is f/2.8.
Next: does it shoot good pictures of children? Yes.
E poi – how is the bokeh? Strangely, it’s actually really good, especially for a wide lens. Here is the sequence f/2.8, 4, 5.6, 8.
Sunstars? Got ’em too. Here is f/2.8-8 (clockwise):
Gross resolving power (again, f/2.8-8):
And now, we laugh at your Elmarit-M!
Flare resistance, same range:
Another test; can’t remember why. Seemed like a good idea at the time.
