Was wondering if anyone has shot 4k with Rokinon glass? Curious to know if they hold up at such a high resolution?
 
I own and love the 85MM F1.4..... But I have never thrown it up on a chart or projector. But it looks and behaves really well on my R1MX

Matt Duclos did a a thorough test of my next acquisition though, the Rokinon 35MM F1.4 on his blog.... (Really he indicates it os closer to a 30MM, which is actually even better and more of a spread from the 2 50MM F1.4s I already have)

Extremely helpful....thanks Scott!
 
Very nice glass for the price, and slightly stopped down it holds well on a 5D in photo mode, which has more photocells than a RED.
 
I have the 85 and 14 and I love them both but I use them on the 5D and FS-100. They are killer lenses for what they cost. I would wager that they would hold up well in 4K.
 
I've dealt with the 85mm before. I believe Bower & Rokinon are all Samyang lenses rebadged. Eitherway, they're actually a fairly decent lens for the price. But can't comment on their performance at 4k or even 5k for that matter.
 
Thanks everyone! I'm going to get the 35mm and see how it holds up with my lady Scarlet (which should be soon!)
 
I just got the 35mm 1.4 Rokinon today. It is a little sharper at 1.4 then the Nikon 35mm ais at 1.4, no doubt. Nikon seems to have a fair amount of bloom or veiling at 1.4 as well. When contrast is added it's not too bad on the Nikon, but you have to work it. At 2.8 they pretty well even out with sharpness and contrast.

Just did a night test as well at 1.4 and similar veiling on the Nikon. However, sometimes it can look good, and when you pull focus on the Nikon those night lights have a beautiful Bokeh ring, similar to the 50mm 1.4 Nikon and the 85mm 1.4 Nikon (two of my favorites on the Red One and Epic). The Rokinon is okay in the Bokeh dept, but not as nice.

The big issue I have with the Rokinon is when you pull focus - the end focus mark does not end up being in the same place if you are pulling one direction as opposed to the other. This is more prominent at about the 6' mark. Not as bad further away. Something's weird with the mechanics. It's almost like a strange buffer. On the Nikon, it's a no brainer - bang on in both directions. I don't know if this copy is problematic and others are better, but this and the bokeh may be deal breakers for me. I was hoping to be blown away, but I think I may be sending this lens back. I have to sleep on it.

Hi there HildeBrand, let me ask you something, with your Nikon mount rokinon, does the distance scale increase when turned ti the right? 'cause mine does, is that bizarre or is there something I don't know? I have other third party nikon mount lenses and their distance scale increases to the left. What's going on with this Rokinon lens? Did I just paraphrase what you said? lol
 
I have the 14,35,85. Nice build. The 35 is my favorite on the 5D.
 
Has anyone heard of their cine lenses with gears?

They announced the 8mm...
EDIT: found it as Walimex brand, coming mid march for 350€ in all still lens mounts.

I have the 14mm and stopped down I think it's very sharp but the distortion is pretty heavy but doesn't matter much unless you're shooting architecture. (i.e. the sides start warping) but it's great for the price
