[Super35/APS-C] Just have to say this is an incredible lens. First one I received did not have the proper line on it, second one was absolutely perfect and the focus distance markings were exact. Years ago it would have been impossible to buy a lens like this for less than 30k, or 10k. Look up some videos on it to confirm how incredible it is. Large format look on an S35 sensor. Great feeling quality. I have used 50k Cooke lenses, this is a great quality lens from Mitakon.

[T16] This lens is a manual lens, so focusing can be a little tricky, however pared with Sony's zebra focus & focus peaking, it isn't that bad. The results are definitely worth it! This is my favorite lens I own, it has so much character. The bokeh is sooo buttery smooth

[20mm] This is one of the best cine lenses that I've used. It is soft wide open but gives you a good halation effect when shooting indoors especially when you're using practical lights like lamps fairies small accent LEDs. For the price it offers quite a bit of amazing features one of them is zero breathing. I am waiting for a wide angle version of this lens may be a 25 mm or 24 mm to add to my collection. The build quality is on par with that of the Zeiss. It is quite heavy but I do like the heft it keeps my camera stable. Right now I use it on my red dragon as well as my black magic pocket cinema camera. This is a great investment.

[Super35/APS-C] A masterpieces that will perform at global stage

[Super35/APS-C] Lens build is solid and works well. Some focus breathing, but everything else is rad

[20mm] Pros:
Phenomenally capable
Solid build
Center sharpness is top-tier stopped down to 1.6
Quite compact for it's capability
Dirt cheap compared to other f/1's

Cons:
No autofocus
No exif data
Soft wide open but could be a pro due to dreamy effect- a matter of preference

[ 0.8 MOD] I read a lot of bad reviews. My experience is that this lens is great!! Yes, the T.1 is soft, but I always use a Tiffen Black Pro-Mist 1 Filter for my films. So, to me, I enjoy that characteristic of a softer look at T.1. I have also seen reviews saying that chromatic aberration is too much. To me, people in post-production that I work with, spend tons of money on plugins to emulate that characteristic alone. So, to have it in lens already is pretty dope. ALso, this lens comes with a awesome hard case!

The manual focus is no problem for me personally. I have honestly never truly used autofocus much at all in my career. The lens is on the heavier side. Personally, I am very active (I work out, play basketball, and golf) so holding this 4Ib lens vs a 2.5Ib lens from Sigma is virtually the same for me. 

The focus without a focus puller is very smooth. If you use manual focus already and don't use / own a focus puller, then you won't need one with this lens in my opinion. My hands are small, and I can still focus relatively easily with my hands alone. Now, I did buy this lens new and not used. So that may be why there are bad reviews regarding the focus. 

Overall to have a T.1 is unbeatable to me. Yes, the image is softer but that's why we have post-production (color grading in Davinci). This lens has a character that is hard to reproduce in post-production. I look at the cons as a win as a creator!

[7 x 4.7 x 3.9"] Excellent I recommend it and for the price and quality.

[77 mm] Freaking love this lens. Sharp, fast, metal, zero complaints at all.

[Sony E] I was skeptical at first glance that a lens this fast could be this affordable and good. Pretty blown away so far. The lens is all metal and glass. So it’s nice and heavy and robust. Manually focusing on the EOS R is great and the images are very 3D. Excellent sharpness stopped down to f2. For a portrait photographer, this should be in everyone’s kit.
