Rokinon 12mm F/20 Ncs Cs Lens for Sony E-mount Review
Readers inquire me about my photography set up up and camera gear quite often. I've written reviews on my standard kit of a Sony a6000 paired with the Sony 10-18mm wide bending lens. The Sony 10-18mm is an incredible wide angle lens for moments with lots of available light, but I found myself wanting more options for low low-cal situations. I searched through merely well-nigh every available E mount lens and settled on the Rokinon 12mm f/two.0. The closest competitor to the Rokinon 12mm f/two.0 was the Zeiss Touit 12mm f/2.8. The Zeiss came in at $999, whereas the Rokinon was available for $375. Other than toll, the major difference is that the Rokinon is completely manually operated for focus and aperture. I thought this would be a big deal at first, but I've really grown to enjoy the procedure of shooting with a manual lens. I'll discuss this more in my review of the Rokinon 12mm f/2.0. I have the East mountain version of this lens for Sony mirrorless cameras, but it is also available for Canon, Fuji, Olympus/Panasonic (MFT), and Samsung.
**Note that the Rokinon 12mm f/two.0 tin likewise be institute listed every bit the Samyang 12mm f/2.0. In that location is no difference with these two lenses equally they are exactly the same and differ in name merely. **

Lens Construction And Build Quality:
The Rokinon 12mm is a crop sensor lens made for APS-C sensor cameras giving it an effective focal range of what would be 18mm on a total frame sensor. The aperture range goes from f/2 to f/22. The stock-still 12mm lens has a minimum focusing distance of vii.9 inches. The glass uses a Nano Blanket Organisation (NCS) to improve the transmission of light, reduce lens flares and ghosting, and provide more contrast. This lens takes a 67mm filter. The Rokinon 12mm is congenital like a little tank using a combination of metal and plastic. Coming in at 8.64oz (245g), this lens is not the lightest, but it handles very well.
As I mentioned higher up the Rokinon 12mm is a manual focus lens that requires user manipulation for aperture and focus. The aperture band is solid and has a overnice clicking experience with each turn. The focus ring is smoothen and house, with the perfect corporeality of stick.

Focusing:
For those new to a transmission focus lens, the new procedure tin can seem a flake daunting. In the new historic period of digital photography, it's like shooting fish in a barrel to get used to just aiming a photographic camera and snapping abroad. In that location was a time not likewise long ago that auto focus cameras and lenses didn't be. Having a manual focus lens has brought me back to this age of photography, and in a lot of ways, has helped me hone my craft every bit a photographer. That being said, I use the built-in focus peaking engineering science of my Sony mirrorless camera to ensure my exposures are not out of focus. This is particularly helpful when taking photos around f/2.0 with a shallow depth of field. Missing focus at this aperture unremarkably means a blown shot. My a6000 allows me to set the focus peaking color to yellow, ruby, or white, and and so highlights the focused parts within the viewfinder to let me know I'm locked on. When I first started using this lens, I'd have a few shots from every outing that were out of focus, but with a little practice, I've improved quite a fleck.
Image Quality And Functioning:
For me, the most important matter to run across in a camera or lens review is the 'real life' epitome quality. In this department I'll talk about and show pictures to demonstrate the Rokinon 12mm f/two.0's abilities in low light, flare, bokeh, vignetting, baloney, it'southward ability to 'become close', and it's functioning while hiking outside.
Low Light
The main reason I purchased the Rokinon 12mm f/ii.0 is so that I could shoot more than handheld shots in low calorie-free. I about never travel with a tripod, and so getting quality handheld shots in depression lite is a must for me. There is no substitute for a tripod, only below you can see the kind of shots I've been able to go while walking around in low light situations. My a6000 handles very well up until about ISO 3200, with noise levels very manageable below that. Having an f/2.0 lens allows me to keep my ISO below 3200 in almost all low light situations.
Flare
While shooting outside, I haven't had as well much of an issue with flares. The Rokinon 12mm comes with a lens hood that I don't use due to the constraints of my hiking camera purse. You can see what the flares look like in the image below. They are very easy to remove in post processing.
Bokeh
For those that aren't familiar with the term, bokeh is the blurry out-of-focus area in a photograph. As you can see below, the bokeh of the Rokinon 12mm is quite pleasant, but non as nice as what you'd expect with the Sony 35mm or 50mm offerings.
Vignetting
Vignetting is the light falloff, or dark corners, plant in an prototype. The vignetting on the Rokinon 12mm is strongest at f/2.0, simply falls off considerable as I approach f/viii. You can expect at the corners at some of the photos in this review to see the vignetting on the 12mm. Most of the time when I'thousand shooting at f/2.0 I'g composing a shot in low light so the dark corners are hardly noticeable. This is some other exposure issue that is very easy to correct for in post processing.
Distortion
One of my favorite components to play with in photography is perspective. The presentation of perspective can actually carve up a good photo from a bully photo. A broad angle lens like the Rokinon 12mm is going to exaggerate perspective due to the fact that there is more altitude between the object being photographed and the lens. This is why people or objects in the foreground of a wide angle exposure will announced larger than objects further away. Having a wide angle 12mm lens really allows me to play with the depth of scale on landscapes. The one issue on broad angles that can cause problems with perspective is distortion. Distortion is when a lens presents an image with curved lines even though the lines are really directly. The 2 nearly common types of distortion are barrel distortion (for broad bending lenses) and pincushion baloney (for telephoto lenses). With butt distortion, directly lines will curve outward from the heart of an image, like a ball is pushing towards you from behind the photo. In that location are time when distortion makes a photo more interesting, but in architecture shots distortion tin be a distraction. Luckily, baloney is easy to fix using lens profiles in Lightroom. Here are some examples of distortion in the photos below.
Getting Closer
Many people assume that the sole purpose of a broad angle is to let the photographer to capture more of what they're seeing. This is true, merely my favorite office of what wide angles offer is their ability for me to become closer. When shooting with lenses higher than 18mm, I often detect myself having to stride far abroad from an object to capture information technology. With a wide bending, I'm able to stay close and capture everything that my eyes are seeing. This is especially important when I'm indoors and don't accept the option of creating more space with my feet.
Hiking Outdoors
When hiking outdoors, I still prefer to use my Sony 10-18mm, as I almost never feel express by it's range of f/4. Still, the Rokinon 12mm has proven to be a very serviceable hiking lens, too. I've used the Rokinon on a number of hiking outings and the results are on par with my Sony 10-18mm.
Closing Thoughts:
The Rokinon 12mm f/2.0 is an fantabulous lens choice for those looking to shoot in low calorie-free. I wouldn't suggest the Rokinon 12mm as a starter lens for newcomers to photography or every bit the sole lens in a photographers kit, just instead as a low light tool for those looking to ameliorate their images when lite is scarce. At under $400, this lens is a bargain compared to the competition.
