I am using a Canon 600D with a 50mm lens. I want to buy a wide angle lens for around 300$. After searching, I found the Rokinon 14mm and the EF-S 10-18mm are in this price range. Both lenses have some pros and cons. For example, while Rokinon offers f-2.8, it is built with manual focus. On the other hand, the Canon 10-18 offers only a max aperture of f/4.5-5.6.

My main interest is in daytime+sunset landscape photography. In this circumstance, which lens would be best-suited for me?

    \$\begingroup\$ What's more valuable to you, (autofocus plus flexible perspective) or (a wide aperture for lower-light shooting)? Buy the lens that is going to fit the way you use it better. \$\endgroup\$ Aug 10, 2018 at 20:09

It's up to you. Everybody's priorities and personal tastes in framing are different. Which lens is going to be the better fit for you depends a lot on what/how you plan to shoot (handheld or on a tripod), whether you plan to move to a full-frame body in the near future, and how wide you want the lens to be able to frame a scene.

The Samyang/Rokinon lens is designed for full-frame. It has a maximum aperture of f/2.8, and so may be better suited for handholding or environmental portraiture (indoors) and low light. But it's 14mm, which on a Canon APS-C sensor, has equivalent to a 21mm lens on full-frame. And it doesn't zoom. And if you're shooting landscapes, there may be a physical barrier (canyon, cliff, wall, etc.) that may make it difficult to "zoom with your feet" if you want a wider view.

The 14/2.8 is ultrawide on a full-frame body, but it's only very wide on crop. Ultrawide with APS-C tends to start at 12mm. And the front element is convex (bulbous) and juts out so there's no way to use a screw-on filter with it; instead, it requires a special filter holder. Landscape shooters often may want to use a polarizer or graduated neutral density filter.

It is also a manual lens that doesn't have any way of electronically communicating with the camera body. You not only have to set the focus manually with a lens ring, you also have to set the aperture that way, too. Your 600D can do stop-down metering so you won't lose metering accuracy the way a Nikon D3x00 or D5x00 user of the 14/2.8 would. But you can only really use the Av or M shooting modes (i.e., modes where the camera doesn't adjust the lens's aperture setting). And you are also going to lose lens EXIF information (lens used, aperture setting used, etc.) It's not just autofocus you're going to lose. But not having to bother with the electronic communication protocols is how Samyang makes their lenses so inexpensively for so many different camera mounts.

The EF-S 10-18 f/3.5-5.6 is designed for an APS-C sensor, so if you move to a full-frame body, you will probably have to swap this lens out for another ultrawide. And it is slower, being only max. aperture f/3.5 at the 10mm end of the range, and f/5.6 at the 18mm end, so it's probably only useful outdoors, in good light, or on a tripod. But it zooms all the way out to 10mm, so it's substantially wider than the 14mm, and gives you a great deal more framing versatility. And it reports to the camera, so you'll have autofocus, lens EXIF, and wide-open metering, as well as access to all the camera shooting modes. It also takes 67mm screw-on filters.

Which lens is the better choice for you, depends, as I said, on your specific needs/preferences.

  • \$\begingroup\$ Thank you very much. I realized the pros and cons of both Lenses. As I am not moving to FF very soon, I decided to buy Tokina 11-16 f 2.8 AF. I think it will cover the major disadvantages of those lenses. \$\endgroup\$ Aug 12, 2018 at 1:07
  • \$\begingroup\$ @BloodstoneProgrammer. Huh. A fast max. aperture typically doesn't matter that much for landscape shooting, where most folks use a tripod so that they can stop down for sharpness and DoF. To me, the 11-16/2.8 is a better fit for environmental portraiture or night sky shooting. But happy new lens! \$\endgroup\$

If your main purpose is landscapes, you can typically use a tripod for that, and your subject isn't moving, so the speed advantage of f/2.8 probably isn't of much benefit.

On the flip side, the Rokinon lens is an EF lens, which means if you ever move to a full-frame body, you can keep using it.

On the flip side, the Rokinon lens is manual focus, which is generally a pain.

I would expect that you'll be happier with the Canon lens, simply because the one main benefit of the Rokinon isn't that much of a benefit for what you're shooting, unless you also plan to use the f/2.8 for some other purpose. But ultimately, all we can do is list the pros and cons. The ultimate decision is more a matter of opinion.
