Ca. 1953/54 version, great lens, one of the best vintage non Leica lenses for a LEICA M8 or M film I think, the 1949/52 "Tokyo" ones shoot smoother creamier Bokeh styles and the post 1953 "Japan" ones a sharper still creamy REAL SONNAR look and that's just MY opinion really, (SAME LOOK GOES FOR THE VERSIONS OF S.C. f1.4 AS WELL)
I use a 1955 one..........I love the results with color and the B&W's look great too, a lens for everyone who wants that true "Retro" look in their photos. 😀
I just go by what MY PinUps look like after I use this thing 😉 Really any era of these H.C. f2's is kickass, one of my favorite lenses of all RF lenses to really use on a daily basis 🙂
Greedy dealers have pushed the prices up lately, they are not a rare lens, but just hard to find in good shape, while all the shooters back in the 1950's KNEW that it was a keeper and they kept them till they wore out!
Enjoy it Raid, you have a nice example there.
