Out of curiosity, how do people focus 50mm @ f1.2 with manual focus? Not by distance / hyperfocal, I assume 🙂
Using a combination of the back LCD’s large size, focus peeking, and zooming, I assume.
🙂
I focus without poblems using zoom focus + focus peak using:
Sammy 85mm F1.4 + Lens Turbo II = 60mm F1.0
it’s just a little bit harder .
Most likely non-moving subjects then?
…it’s a wide angle…which moving subject u mean ?
85mm is wide angle? or you mean the 42mm (21*2 on MFT)?
21mm it’s WA, while 85mm i use it for portraits
on MFT that would be equivalent of 42. Still not wide angle.
all manual lens are useless…
all AF lens without OSS/VR/IS are useless …
all cropped format Camera are useless …
😀
I did not say that. I asked how you focus. Person is moving around, at 42mm equivalent and f1.2, good luck focusing on the person.
I have done my fair share of manual focusing using hyperfocal distance with rangefinder film cameras, I know what I am talking about.
..using Focus peaking and Zoom on viewfinder…it’s very simple to focus
Simple, but not fast and not for moving subject. Even static subject, very hard to focus on the eyes, if you have razor thin DoF
The 21mm will be slightly wide angle on Fuji X mount and Sony E mount.
..my 85mm+LT2 setup , i use it for portraits
I’ve never used a f/1.2 lens, but DoF on a f/1.4 lens isn’t much different. Some lenses (200/4) are even thinner.
It’s not that hard with a little practice, at least with a EVF. It’d be hard to do it well on a modern DSLR lacking a decent focusing screen.
I got all excited until I read the APS-C part.
Bah, I didn’t even notice that. What a bummer!
I think 50mm is a focal length with low usability on 1,5x and 1,6x crop. For mFT the focal length is good for portraits but then it should have AF.
21mm f/1,4 is quite unique on Canon, Nikon, Pentax and Sony mount. Should be very useful for aurora photography and the night sky if coma is low.
Aurora photography was my first thought – I assumed this was a FF lens. Still, it’d be nice for aurora on crop bodies. I use between 28mm and 50mm pretty regularly on FF for aurora photos.
It could be good on FF as well, even if you get a strong circular shade.
I plan to use my Samyang 8mm f/3,5 on Pentax FF later on. Now i have a 180 degree diagonal, rectangular fisheye. On FF, without the hood, it will be a 190 degree circular fisheye. Look from 1:40

Not so amazing for me considering 50 mm is bigger and heavier than its FF, designed for SLR counterpart from Pentax or Oly. It better be darn good wide open. http://www.bdimitrov.de/kmp/lenses/primes/normal/A50f1.2.html
Add the adapter and compare them then. I am very curious about the optical performance of these two new lens designs.
You don’t get it. If it was possible to design and produce lens with the same focal length and aperture for full frame SLR, then mirrorless version designed for APS-C sensor should be somewhat smaller and lighter not bigger and heavier. Of course most of these SLR 50 f1.2 lenses have image quality so-so wide open, so the only excuse for this Rokinon would be to have great performance at f1.2.
Vintage lenses are old designs with old coatings (not optimized for digital photography). Size and weight should only really bother m43 shooters, since they can get the Zhyongi 50mm f0.95 which is a lot smaller and cheaper too.
No one is forcing you to buy these lenses, but you should be glad someone is making lenses for short flange distances. Have you even used one of Samyangs mirroless lenses? They are built to last and optical quality is superb.
No, you don’t get it. If you’re going to compare this new lens to old SLR designs, you need to add the adapter length and weight. On mirrorless, any 50mm lens is going to be longer than a SLR equivalent, especially one for a mount with a long register distance like OM and K mount.
On top of that, yes, these old 50/1.2 lenses tend to be a bit soft wide open. It’d be foolish to expect this new Samyang 50/1.2 to be corner to corner sharp wide open, but I do expect that it’ll have less SA and more contrast wide open in the center of the frame than old SLR 50/1.2s.
Vintage lenses exists in all price and quality ranges. Good vintage lenses with good coatings and hood perform remarkably well on digital cameras compared to younger alternatives. Example: The Super Multi Coated Pentax-A 50/1,2.

I already own a vintage 50mm 14. and for the price it is amazing. But finding a good priced vintage lense that you can try out before you buy is not always an option. And the street price of Samyangs is going to drop, so they won’t be that much more expensive from their vintage equivalents.
Samyang should really consider putting a chip with EXIF data in their mounts – that would make them even more awesome. Also, the could implement a switch to go from clicked to declicked aperture (and become the cheaper Loxias).
When will Samyang start to make good big telezooms? (No the 650-1300 f/8-16 is not good) and good long telephoto primes? (No, the mirror-lenses isn’t good)
When will Samyang start to make AF lenses?
