I cannot really see a clear line when it comes to aperture constructions of TTArtisan lenses yet. Out of 5 lenses I saw 4 different aperture diaphragms. This one features 12 blades and might become my favorite among those, as it yields well defined sunstars between f/8.0 and f/16. The alignment of the blades is not as perfect as it is with Zeiss Loxia or Voigtlander lenses though. Le Kamlan est le champion de la quantité de flou d’arrière plan avec son ouverture de F1.1 et sa distance de mise au point de 40cm
The TTArtisan 50mm 2.0 is the smallest 50mm lens for the fullframe mirrorless systems I am aware of. It is about the same size as the smallest SLR era 50mm lenses like the Nikon Series E 50mm 1.8 – quite the achievement!If this 1,200×900 pixel crop is about 12" (30cm) wide on your screen, the complete image would print at 35×52" (0.9×1.3 meters) at this same magnification. Field curvature : if the centre is in focus , the corners won’t and vice versa, so not the best lens for Architecture or Landscape Recently there are a lot of hype about rangefinder lenses adapted to mirrorless cameras, such lenses from olympus cameras like 40mm 1,8f, those are pancake style lenses, they need adaptadion, usualy simply gluing them to the third party helicoid is enough to get a focus going from ~10cm towards infinity. A lot of those lenses offer surprisingly good sharpness some even across the whole frame, and their price is in the range of this one. Although those lenses can not be stopped down or they offer very primitive aperture mechanisms.
Regarding the ninja-star aperture shape and possible reduction of focus shift: at this point I can’t recall the exact source; it’s one of those ‘things I read on the internet.’ I have a theory about why the shape might minimize focus shift, but since I’m not an optical engineer and have no way to verify it, I’ll refrain from potentially digging myself further into a hole. 🙂 Shot wide open this lens has some of the best looking bokeh I’ve seen in a long time. Taking the price into consideration this shouldn’t even be possible. It’s really that good. Compared to the expensive plastic rubbish offshored to China by Nikon and Sony, this is a gem of domestic Chinese precision at a bargain price. This lens is like a breath of fresh air after reviewing countless high-priced throwaway plastic lenses from the big names. This lens should last at least a lifetime; there's nothing to break or go obsolete. It is recommended to have a look at this article first to get an idea how this brightness graph works.
Image Quality
In the center of the frame almost every lens will render a perfect circle, but only lenses with very low optical vignetting will keep this shape in the corners. So why do we need to even look at options from third party manufacturers? I can answer that question from my own personal point of view, for sure. Fujifilm’s lenses are optically excellent and, for the most part, cover my day to day photography both personally and professionally. However, there are times when I want to work with a lens that’s a little less than “perfect” and times where I want a lens that is smaller and lighter than Fujifilm’s offerings (think Laowa 9mm f/2.8 vs XF 8-16mm f/2.8). With that said, let’s look at a very cheap offering in the world of third-party lenses: the TTartisan 50mm f/1.2. Build Quality and Usability While this lens is at least as sharp as any LEICA 50mm f/1.4 lens, that's not saying much as neither of LEICA's 50/1.4s have ever been that sharp compared to Nikon and Canon's lenses. They're all sharp at normal apertures, while all of the LEICA-mount f/1.4 lenses get softer in the corners wide open. For that price it is a great option to bring next to your big zoom lens as an alternative if you want to travel light or need a bit more speed every now and then.
Technicals are pretty good with this lens and it’s performing better than expected for an f1.2 that is this compact. Made-in- U. S. A. Davis 6250 weather station, 19 December 2020. LEICA M9, TTArtisan 50mm f/1.4 ASPH at 1/ 4,000, 1/ 4,000, 1/ 2,000 and 1/ 750 at ISO 80, 160, 160 and 160, Perfectly Clear. I tried to shoot in various situations. One thing I really like about this lens is how well it holds detail at far distances even when wide open, so you get that nice subject separation even at a good distance. The Samyang 50mm F1.2 AS UMC CS (480 euros) has a bit better sharpness wide open , has better contrast and is more resistant to flare but the price is completely different It appeared to be in focus, and the focus peaking indicators on my Z6 II would say that it was, but I often saw that the focus was off in the final image. And this wasn’t just at f2; I saw this all the way until f4 even. With every other manual focus lens I’ve used on this camera, even at f1.4, the focus peaking was accurate. Even when the depth of field was shallow, it was always accurate. If it was off, it was either because the subject had moved out of the focal plane or I did. Now at f2, I was willing to blame myself for not being steady enough to nail the focus. But when there was sufficient focal range at apertures like f4, I was stumped over why the focus would be off.Optics manufacturer TTartisan has announced two upcoming manual prime lenses: a 35mm F2 APO ASPH lens for Leica M-mount and a 50mm F2 lens for full-frame mirrorless camera systems. TTartisan 50mm F2 The TTArtisan 50mm F1.2 lens is constructed of seven elements in five groups, has a minimum focusing distance of 50cm (19.7”), uses a 52mm front filter thread and has a 10-blade aperture diaphragm with an aperture range of F1.2 through F16.
Also, there is some fringing that will happen along the edges of bright bokeh edges in the out-of-focus highlights. If you find you really like this focal length, the Fujifilm XF 50mm f/2 R WR may be the next step, or upgrade, in your photography gear journey.Cons– Noticeable field curvature, chromatic aberrations on out-of-focus high contrast edges, vignetting wide open, noticeable distortion, only 100-degree focus throw. It manages to accomplish something where even some of the fast Voigtlander lenses fail: stopped down it is plenty of sharp across all of the frame. So, what do you get for investing in the big boys from Fujifilm? The obvious benefits are autofocus and a warranty. However, there are plenty of subtleties that make Fujifilm’s lenses. Small things like precision machining and attention to detail make Fujifilm’s native lenses feel that much better. You also get electronically controlled apertures and EXIF data recorded by the camera. On top of that, they’re optically superior when it comes to wide-open sharpness and flare characteristics. In practical terms all of these lenses is sharp in the center where we need it, at every aperture. The LEICA SUMMMILUX-M 50mm f/1.4 ASPH and this lens are particularly sharp in the center at f/1.4. however all these f/1.4 lenses become softer towards the sides in the lab at f/1.4. Much of this can be caused by field curvature. Des 3 optiques, le TTArtisan est le moins lourd et de loin le moins cher. La qualité de construction est très bonne et similaire. Le TTArtisana celui avec la distance min de mise au point la plus importante. Le Kamlan est le seul ave cine bague d’ouverture sans clics (meilleur en vidéo)
