The tt art sound 50 millimeter, f, 0.95 lens for aps c cameras in sony e mount, although its also available for the vast majority of other mirrorless camera systems. Well, i might as well review it for you might, and i i later found out it was ttrtan themselves, not one of their distributors, who sent me the lens. So id like to say thank you for that, although, as usual, this is a totally independent review. A 50 millimeter, f 0.95 lens on an aps c. Camera is great for portrait and subject. Photography. Something you might also be interested to know is that the lens works quite well on full frame. Im, shooting it here on a full frame. Sony, a7r iii. Here is the full frame image at f, 0.95 and heres another at f4, where you can barely see any vignetting at all, so for its price of about 220, us dollars youre getting quite a lot of lens here, although of course only if its image quality is Acceptable, i dont think were expecting fireworks today, but anyway lets look at its build quality. First, the lenss metallic build quality feels nice and tough, with a distinctive black and silver finish to it, its small, but it has a fair bit of weight to it due to being so packed with glass. The first obvious compromise is that this is of course, a fully manual lens. The manual focus ring turns nice and smoothly with a decent amount of precision.

Although a little bit more of a turning circle, wouldnt have gone a miss here. You can see the lens clearly exhibiting some focus breathing zooming in and out as you change focus then, on the top you get an aperture control ring. It has nice little clicks to it at various intervals. Although those f stops arent placed very evenly my copy, the lens came with a screw on cap. Go, i hate those things, theres, also no weather ceiling to be spoken of here. Its front filter size is 58 millimeters wide overall, its a dead, simple little lens. As simple as they come, but still pretty tough and perfectly usable all right lets take a look at image: quality, im testing it on a sony a5100 camera here with its 24 megapixel aps c sized sensor no in camera. Corrections are available with this lens at f 0.95 theres, some sharpness here, but on contrasting edges, its clouded over by ghosting and some color fringing corner image. Quality is very, very blurry. F, 1.4 looks about the same in the corners back in the middle. The image is still a little soft, but contrast is much much higher. Stop down to f2 and image quality jumps up to becoming excellent in the middle image. Corners are still very poor. Unfortunately, stop down to f 2.8 and clarity is slightly increasing in the corners. Now. Stop down to f4 for big increase in resolution in those corners and at a 5.

6 they look excellent. The lens stays the sharp down to f11, but at f16 softness creeps in due to the effect of diffraction overall well. This is quite a low quality lens when it comes to sharpness and contrast, especially at its brightest apertures. However, it will perform a bit better when youre shooting it at infinity and not at normal distances. Alright lets take a look at vignetting and distortion now on an aps c camera the lens projects a little barrel distortion, but its nothing too disturbing at f, 0.95 vignetting is actually very low already. This will be because of that almost full frame coverage. We saw earlier the lenss minimum focus. Distance of 50 centimeters is slightly further than average for a 50 millimeter optic close up image quality is dreadfully ghostly at f 0.95 at f 1.4. Things are only a little better, however, stop down to f2 for a lot. More contrast there and at f 2.8 close up image quality becomes excellent. Lets see how the lens works against bright lights. Now the lens displays a lot more flaring than average here keeps away from bright lights and, while were working in the dark lets, take a look at coma levels that comes mowing is pretty wild. Well, what you can see through the corner softness anyway, that is at f, 1.4 f, 2 and at f 2.8. It gradually gets tamed down, lets zoom out and take a look at the sun stars.

Now they begin to really emerge at f 5.6, getting more defined at f, 8 and f 11. As you can see, now, lets take a look at the quality of this lenss bokeh at f 0.95. The lens can get you some dp autofocus backgrounds. Generally, they look averagely smooth, although in the middle distance, bright points of light, do have a green outline to them, not to mention a seemingly ubiquitous cats eye shape at the brightest aperture and finally, related tobacco comes longitudinal, chromatic aberration at f 0.95. The close up softness is almost overwhelming here, so you cant really see much of anything at f, 1.4. Its the same problem stop down to f2 for some notable color fringing on bokeh highlights, though, and at f 2.8 its reduced and at f4 virtually gone overall well. Theres no beating around the bush here. This is not a high performance lens by any stretch of the imagination and manually focusing it can be tricky its basically a super cheap way for you to get yourself down to f 0.95 for pictures with deeply autofocused backgrounds, which do, admittedly, look quite nice. If you dont care too much about sharpness Music, oh youre, still there, let me take a moment say thank you to all my patreon supporters who make these videos possible. I love putting them together for you all, but they certainly do take a lot of time and some expense as well.
