Yes, another Soviet lens. The Helios 44-2 is a copy of the Carl Zeiss Biotar and known for its "swirly" bokeh - a feat not easily reproduced. In fact, in the example below, I didn't even see it on camera - it wasn't until I playing with them in post that I noticed it. Given enough time, I will get better at catching the correct distances bewteen shooter and subject, and subject and background.
As it stands, its a fun lens to keep on my camera when I'm just hanging around. And while the aperture isn't exactly fast, I am always surprised at the narrow depth of field despite its f/2. Narrow enough I suppose. The aperture setting once again is in the very front of the lens, but as with the Jupiter-9 it contains an aperture lock, which helps tons in that location.
I ran out of 49mmm filters, but happened to have a rubber lens hood (the Canon EF 50mm f/1.8 STM has its own hard plastic fitted hood like the EF 70-200mm F/4 USM but I haven't ordered it yet) which does what I want it to for the time being. This lens is a little rougher than my other lenses having the black paint rubbed off in a couple of places, but the focusing ring is smooth and effortless.
At 58mm its little longer than most of my primes (APS-C 93mm) but hardly noticeable unless you're swapping lenses on a tripod pointed at a static target. Just saying.
You can make out a slight swirly bokeh on either side of the hay, near the edges of the frame.
Slight swirl here just around Big Puddy's big head.
