Here are a couple of portraits I shot with the Helios 44M-4. This vintage lens is known for its unique, swirly bokeh. I find the effect is most noticeable with multiple point light sources some distance behind the subject. Christmas light work well. The lens is not too sharp away from the center when wide open. So with this particular lens, I find it works best to place the subject in the centre, violating the rule of thirds. It's a fun lens to play with, and I like the dreamy look of the photos.
