@goanna thx mate , yes also about aperture pin , do you have a cine version? how about the quality of this lens?

I got 17,5mm voightlander that become a 40,2mm on 4K 2.3x crop mode on the GH4 . The Samyang 24mm with a speedbooster become a 38,5mm on 4K 2.3x crop mode on the GH4
I wanted to know if you think it was worth buying it

sorry my English : )

I would like to buy a cine lens Samyang 24mm T1.5 ED AS IF UMC (nikon mount) for my GH4.

someone could tell me if there are problems with SpeedBooster metabones nikon g to MTF ?

thx

Amazon has a very nice deal on these right now in Four Thirds (not µFT, but can be adapted easily). The 14mm too, seems they are selling these out – who is filming with a Four Thirds anyway?

I'm not seeing it on the 85mm, haven't used the 24mm as much yet.

I took delivery of the 24 and 85 yesterday and am very pleased. Excellent construction, optics, and everything is working great. The 85 has a noticeably tighter focus than the 24, almost too tight, but it will probably loosen up a hair over time.

I got the Nikon versions so I could use them alongside my existing Nikkors on my 5D, 7D, GH1, and the D800 and GH2 I will be using next month. My only disappointment with the entire affair was that even Cinevate and Novoflex EOS to Nikon adapters had significant play on both lesnes, but some screwdriver work on the adapters and a tiny touch of gaffers tape has fixed that, and everything feels rock solid.

As a side note, I seem to be able to focus better on a 5D focusing screen if I don't have my Z-finder on and am snapping stills with these Rokinons than I can with old Nikkors...not sure why that is, yet.

A new review by ePhotozine: http://www.ephotozine.com/article/samyang-24mm-f-1-4-ed-as-if-umc-lens-review-19623

Pros: Samyang crisp look @ 24mm, 25cm min. focus, F1.4, huge manual focus barrel, step-less aperture version.

Cons: Soft wide open but usable, F2.8 is much better. 3 stop vignetting wide open but if we use the lens on M4/3 these problems are negligible as we are using the sweet centre :)

Personally I want to finish of my set of Samyang 35mm, 85mm + CZ 50mm 1.7 with this last wide angle. But I will wait to see if they make any improvements to the lenses in the coming months' cine versions.

Wow, these Koreans got it right again. What I love most from my 85mm, the beautiful Bokeh, is here as well – and that's rare for a wide lens. If the reviewer writes. "Wide open performance for this lens is a tad bit disappointing considering that I’ve shot with many other lenses wide open and they were much sharper. … With that said, it’s good, but it can and should be much better." he doesn't get it, IMHO, if he later states: "Wide open though, the bokeh looks absolutely wonderful and incredibly film-like."

All the lenses which are super sharp wide open have an ugly Bokeh, as far as my experience goes (and I've been in photography for quite a while). It's connected with spherical correction.

I'm very grateful that Samyang had the guts to go manual in this auto-everything world and is trying to achieve the right balance between sharpness and OOF quality. They are more and more becoming the poor man's Leicas in a world where all others are just counting lines per mm. I wish them all the success they deserve.

I only wish for a GH2 with a larger sensor now ;-)

If you go Nikon it will focus opposite to everybody else, so I'd vote for Canon if you are not used to Nikon.

@stonebat good to know, it looks like an amazing lens

@stonebat I know you mentioned breathing several times before, and you even returned the 35 because of it. Were you referring to the actual "breathing" where focus influences zoom or just mechanical fit and feel? I do not see it as a defect, more as a creative tool, especially with digital... God save me from line binning and skipping, moire and blocking, but bring on the breathing, coma, flare and anything non digital really.

Samyang 24 1.4 seems to be an alternative for Nokton 25mm for price and for usability on 5DmkII full frame. But I want know if people selected Nokton for best bokeh really can find difference with Samyang 24 1.4? I already own Panasonic-Leica 25mm lens but unfortunately I almost don't use it I use 20 1.7, 45 1.8, 12 2.0, 35 1.4, 85 1.4, 7-14mm (in order of usability for events) but not 25mm... But on 5DmkII cheap 50 1.8 is a best fast prime for me, after 24-105mm, 17-35,70-200 zooms Maybe I need really nice bokeh for begin use 25mm. I can't find any compares Nokton 25mm vs Samyang 24mm. It can really help me if somebody find examples for compares.

@Vitaliy_Kiselev @stonebat I will, as soon f%^&&* blizzard slow down a bit, so that I can reach the office.
