[L-Mount] What a gem of a lens. Built like a Swiss watch and performs exceptionally well, and oh the bokeh.

[31.2°] Lens is built great. Has great bokeh and subject separation, which is why you buy the tool. Yes, it is a little soft and has chromatic aberration, but it's better than every other lens trying to be the Leica 50mm.

[L-Mount] The TTartisans 50mm F0.95 lens is a very usable lens.
Very good sharpness at higher apertures and great bokeh at lower ones. Not as sharp at F0.95 as the Leica but very adequate and Loys of fun while saving
thousands of dollars

[31.2°] I didn't expect a Noctilux at 1/18th the price. I've never used a Noctilux 0.95 (although I did own a 1.0 in the 90's and found it hard to nail focus on my M6, but loved the look when I did). I've had the 1.2 Canon 50 & 85 and eventually got rid of them for commercial work because it was too hard to nail focus (either me or the subject slipped out of place), but always loved the look. I'm using this lens with my Leica SL and Sony A7r (both with adapters) and due to the ability to punch in to focus, pretty much nailing it every time. At 0.95 (why shoot any other stop) there are areas of the frame that are sharper than others, but nothings truly sharp, just sharp-er - that's pretty much every fast lens. Once you learn those spots, all is good. Stop it down, it just gets sharper and less finicky - excellent in fact. I actually thought I'd try it, be disappointed, and send it back, but after less than a week, it's a keeper.

[52 mm (Front)] I have the M10 Monochrome, and yes, I feel like a camera snob, but this lens is wonderful particularly for portraits. And honestly I haven't done much with the higher f stops. The bokeh is what one would expect from an f0.95, and the process and results for focusing is just like name brand Leica glass in the M10. At a price less than 10% of the Leica Noctilux, if you're seriously torn between the two, it would totally be worth your time and money to get on a plane, visit B&H, and try this lens! Or better yet, just buy it. High likelihood you'll giggle with delight at what this lens can do, particularly at this price!

[50mm] This is a bargain and a great creative tool.
Lens is dreamy wide open, offers sharp pop at 1.4 / 2.0, and then of course gets excellent sharpness when stopping down, though vignetting is present on my copy.
It IS heavy, extremely well built, focus is smooth & firm, aperture clicks in 1/2 stops, comfortable, neither loose or too firm.
I would have wished for both rings to have slightly deeper grooves for better traction when quick adjustments are needed.
Overall, a great lens for the $$$.

[50mm] I'm keeping it. I would for 3x the price. I do not own the Noctilux 50/0.95, but I do own the Summilux 50/1.4 ... which is among the best glass ever made. And this lens may well replace it on my SL2. I wont be letting go of the Summilux, but this lens has more character and lends to the look I want. I have seen far more expensive glass produce worse CA wide open, including sample images I've seen out of the Noctilux 0.95. I can produce images with this lens @1.4 that have a look very closely resembling the Summilux... though slightly less contrast in the focal plane. All said, I'm very pleased. The build quality is outstanding. Cons: 1. The focus ring is a tad stiff for my liking. 2. It's heavy, but I'm ok with the center of balance feel on the SL2.

[50mm] This lens has me excited about photography again. Its gotten me out shooting more often and frankly finding different ways to incorporate it in commercial work. I can't believe it's under $1000, when the the closest two lenses are $8k-$12k!

[Manual Focus] As its label (50mm f/0.95) would suggest, this lens is an extraordinary photographic tool, either on an M-mount (Leica) camera or, with various adapters, on mirrorless cameras (albeit with manual aperture & manual focus). There's no issue with focusing accuracy with a mirrorless camera, of course, but with an M-mount camera the maximum aperture (f/0.95) accurate focusing may require an adjustment to the lens to work precisely with the camera's rangefinder, and TTArtisan kindly provides the tools and instructions for doing that. My copy of this lens, however, was perfectly adjusted right out of the box (whether that's the exception or the rule, I cannot say). This lens used good materials (metal) and is well put together---a quality product. Is this lens a paragon of optical perfection? No, far from it, but you don't buy an f/0.95 lens for that; you buy it for the unique effects you can obtain at maximum aperture. Is it a world-beating built-like-a-tank masterpiece of optical and mechanical construction like the Leica 50mm Noctilux? No, of course not, but it also costs only about 6% of the price of a Noctilux ($755 vs. $12,795), which makes it an extraordinary value for the money.

[52 mm (Front)] I had tried simpler Lensbaby lenses but never really liked the basic ones because they were too fidgety. I suppose the composer pro might have improved results, but this is a far superior product for roughly the same money.
