Photographyblog posted sthe first review of the new Rokinon-Samyang APS-C E-mount lenses!
About the 50mm f/1.2 lens they write:
Image quality is generally pretty good, especially in the centre of the frame. There are some optical issues to be aware of, though, most notably some minor chromatic aberrations, obvious corner shading until you reach f/5.6, and a lack of sharpness from f/1.2-f/2 in the centre and f/1.2-f/4 at the edges. If you like the effective focal length and don’t mind the lack of auto-focusing or big-brand name, we can certainly recommend the Samyang 50mm F1.2 AS UMC CS as an affordable short telephoto prime lens for mirrorless camera owners.
About the 21mm f/1.4 lens they write:
The Samyang 21mm f/1.4 ED AS UMC’s build quality is reassuringly good, proving to be an ideal partner to the Sony A6000 camera that we tested it with.Image quality is generally good, especially in the centre of the frame. There are some optical issues to be aware of, though, most notably quite prevalent chromatic aberrations, obvious corner shading until you reach f/5.6, and a lack of sharpness wide-open at f/1.4 in the centre and from f/1.4-f2.8 at the edges.

Why buy this glass when You can get a Canon FD 50 1.2 for the same price which fills full frame?
Well. A6000 owners always complain about lacking lenses.
I imagine these lenses have a weight / size optimisation just like that new 12mm Rokinon lens.
yes its a valuable addition to APS-C e-mount !
The weight will be less for sure
This lens has modern coatings and optics and it doesn’t need an adapter. It will also weigh less and you can get it brand new, rather than used. It’s a no-brainer for APS-C users.
Some of the film-era lenses are pretty good but most don’t resolve fine details as well and have significantly worse chromatic aberration compared to modern equivalents. The difference between modern and film tech is most noticeable at short focal lengths.
Not only is the image quality better all around but the old lenses weren’t often made with apertures wider than f/2.8.
The 21/1.4 looks great and I will probably get it. I have the Samyang 100mm Macro and the 12mm f/2. Both are excellent lenses and the price is right.
I’ve got a lot of old glass and a lot of new glass. The Samyang glass performs about the same as the manufacturer glass from the 80s. With slightly better flare resistance.
It all comes down to size I guess. I would prefer to use smaller lenses for APS-C. The Canon 50mm makes good sense for FF users.
Even then I lust after the Mitakon 50mm f0.95. 🙁
Would buy that lens over the Canon 50mm f1.2 if I had the budget.
Find me a legacy 21 1.4 for me to use on my nex. 21mm summilux? Yeah that’s about it 😀
The 21mm will fill a gap for those who want fast ~32mm equivalent lenses , before the only choice was the pricey sel24f18 or legacy glass ..
