Pros and Cons
- A budget friendly lens with excellent performance
- Smooth focusing
- Feels nice
- Big on the Sony E mount lineup of cameras
- Though this won’t be a con to lots of people, it’s a very standard lens that is very clinical in its image creation. Personally, I need some character that helps me to create photos that don’t look like everyone else’s.
- Why no depth of field scale?

For a while now, the ergonomics on Rokinon lenses have always been a let down in comparison to many other brands. They’re built well, but they feel kind of cheapish. Not at all low quality–but instead sort of like their lenses were made in the 1990s. Their newer lineup promises metal and rubber where this has plastic and rubber.
Either way though, for the price point I’m not sure that I can totally be angry at the Rokinon 20mm f1.8. It’s characterized by a two massive controls: aperture and focusing.
The front element is pretty large and in practice works best with circular filters vs square/rectangular filters. You’ll see more of this in our review a bit later.
What you’ll be working with the most are these two rings: focusing and aperture. Since this is a manual focus optic, you’ve got no switches to worry about.
As I’ve stated before, Rokinon’s lenses haven’t always been up to what the other manufacturers output. They’re not badly built, but they feel a bit cheap. This comes with the texture and a whole lot more.
It’s also ginormous on a Sony E mount body.
This lens isn’t weather sealed and has no electronic contacts. So be just careful and use focus peaking.
Focusing with this lens is done manually. If you’re using a DSLR, I suggest that you have either phenomenal eye sight or you use Live View. The same goes for mirrorless camera users: focus peaking will come in a lot of handy here.
All of this ties into the ease of use section.
Ease of Use
If you’re using focus peaking, then this lens will be a breeze to use. Just point, patiently wait for your hand to go around the massive focus throw, get something in focus, and shoot. That’s fairly simple but Rokinon forgot to do one big thing here: add a depth of field scale. What wide angle does doesn’t have one especially when it’s a manual focus optic?
That part really makes no sense to me.
The Rokinon 20mm f1.8, despite all my gripes about the build quality and the ease of use, is capable of delivering some seriously good, albeit clinically sterile image quality. Like a few other wide angle lenses that I’ve seen though, this may be exactly what that crowd of photographers want.
Though I’m sure that this crowd of photographers doesn’t care much about bokeh, you should know that it’s there. Coupled with the very close focusing abilities of this lens, it’s also very creamy due to the wide f1.8 aperture.
I really, really like it.
Remember earlier on how I talked about the front being so wide that it’s tough to mount filters on it? Well, here you go. See how the sides are taken in?
Either way, there isn’t a whole lot of fringing that I’ve been able to find in my sample images.
On top of that, the distortion here really isn’t bad. This almost medium format level quality when you consider it.
This is the least saturated Rokinon lens I’ve seen in a while with the exception of the company’s 85mm f1.4. Again though, this will be good for landscape photographers who do most of their work in the processing.
Lastly, what I’m absolutely floored by is how sharp this lens is even wide open. At f1.8 you’ll get plenty of sharpness but when you stop down to something like f5.6 you’ll be flabbergasted.
Extra Image Samples
- Affordable price point
- Solid image quality for this audience
- Build quality.
The Rokinon 20mm f1.8 lens is a good one. Though I’m not a major fan of its build quality or its ease of use, it more than makes up for this with its image quality for that specific audience. Personally though, I’d probably reach for Zeiss or Sigma.
The Rokinon 20mm f1.8 receives four out of five stars.
