Rokinon Lens vs Sigma Lens

Hello Everyone,

Just a quick question. I am a GH4 Metabones Speedbooster guy, currently my go to is the Sigma 18-35 f/1.8 APS-C lens, But I have seen some awesome video footage being captured on the Rokinon 24mm f/1.5 and the 35mm f/1.5. They seem to have a softer look to me, which appeals, it seems more cinematic. Does anyone have any opinions on these lens, or has anyone used these different brands of lens? T

The rokinon are nicer and are geared where as the sigma is a zoom so its easier the sigma is excellent. so unless your doing really serious films where you have a 1st ac or need the extra low light then i wouldn't get a new lens, would a telephoto like rokinon 85 or canon 70-200 be any useful or some new rigging or lights.

The Sigma is perfect for the GH4 with speedbooster!

The only down point is the limited zoom range.

Also try the 50-100mm Sigma that lens is great as well!

I use both a Sigma 18-35mm and a Rokinon 85mm on my 70D and I do find the Rokinon produces a nicer image. I'm not sure if I'd call it softer necessarily, if anything it seems a little sharper in picking up detail, but it certainly has a much warmer colour; I often hear Sigma's lenses being called a little cold and clinical by comparison.

Of course the Sigma has the advantage of being a '3-in-1' zoom, but then the Rokinons have much nicer focus rings and separate aperture rings too... ultimately, if you have the money for a comprehensive set, and are filming in controlled conditions with time to change lenses regularly, the Rokinons will get you better footage, but it's a trade-off against usability.

rokinons are great. If you follow them on facebook you can find that they do sales on their lenses all the time. Once I saw a flash sale for 50% off.

Here is a question, my speedbooster doesnt show me the number of the f stop with the rokinon lens I recently purchased ( bought the 85mm and the 14mm, just really thinking about selling sigma for Rokinon 24mm, but will see) Now on the lens the f or t stop, whichever the number is 1.5, so with my speedbooster, does it go down to a 1.1?

Glad to hear the subject of ergonomics (how it feels) brought up. They say one person's trash is another's treasure and so it is with lenses. Ergonomics, can you afford it? Comparing is good, but likely either lens will do the job, does the lens work for the type of look you want? and finally, do you know how to apply a particular lens to make it work for your movie? Finding the limits of a lens is good, but even better is exploiting the perceived shortcomings of a lens so it serves to tell your story.
