I am thinking of purchasing a Rokinon 10mm f2.8 ultra wide angle prime lens for my Canon 90D camera. Has anyone had any experience with this lens? I thought it might be a fun lens to work with providing some unique perspective in some photos. Your thoughts?

It would.

On your 90d, it’ll appear as a 16mm field of view and would likely show distortion at close distances. Manual focus, as well, indicates to me that it will be best suited for landscape shooting, where you can set focus at infinity. So, stopped down or not, unless you shoot with a shutter speed better than 1/200, I suggest being on a tripod. I owned a used Rokinon fish-eye for a while and was generally pleased with results…..but, to be honest, quickly grew bored with it and was happy that I purchased used rather than new. I’m thinking you’re interested in the lens for more curiosity than function, so I definitely recommend you shop the used market. All that said, it’s reviews from users is fairly positive, so if you buy, enjoy!

Thank you, good tip

Not sure of the Rokinon price but the Canon 10-18mm is very inexpensive, very sharp and has AF and IS.
Plus it gives you more options than 10mm.
I love the one I have and find it very useful rather than just a 10mm gimmick lens.

I purchased the Rokinon 12mm, f/2, manual lens for use when I'm chasing the Milky Way and Star Trails. It works very good in both of those cases but it's not very good for regular usage because of the distortion at the edges where vertical items have a distinct inward bend.

It's still a fun little lens to play around with as long as you're aware of its shortcomings.

Likewise, every word. Mine cost only $175, open box special. Shop around.

I have three different zooms that each begin at 10mm. Everybody should have at least one !

You're right about the usefulness. I have a Tamron 10-24mm (f/3.5-4.5) and it is a great ultra-wide lens. It is designed for a crop sensor camera but works very nicely down to about 14mm on a full frame sensor.

This is a rectilinear lens. No need for a tripod for daylight. And no need to focus at infinity. It takes a bit of practice to focus a super wide manual focus lens, but can easily be achieved.

On a 1.6x crop body, 10mm becomes 16, so clearly not a gimmick lens, but a great super-wide.

Go for it!

I own three Rokinon/Samyang lens. My 8mm fisheye produces a circular image, but rectangular on my crop sensor 7D II. I use my 14 f/2.8 and 24 f/1.4 primarily for astro shooting always at infinity and wide open. They're very good lenses for astro, especially at their low price point.

While the Rokinon lens would certainly work well on your 90D, I'm not sure that's the best choice. It's a full frame lens and yours is an APS-C camera.

Canon EF-S 10-22mm f/3.5-4.5 USM and EF-S 10-18mm f/4.5-5.6 IS STM are both excellent optically. The more expensive 10-22mm is both faster and better built, while the 10-18mm is a real bargain, has image stabilization, but is a bit plasticky and not quite as fast focusing (although you will see little difference in speed because ultrawides like these hardly need to move their focusing elements at all to go from near to far or far to near).

However, the Rokinon lens is manual focus only... while both the Canon lenses have excellent AF systems.

Rokinon SP 10mm f/3.5 for Canon EF......... $899
Canon EF-S 10-22mm f/3.5-4.5 USM......... $649 (plus $35 for Canon Hood EW-83E or $10 for Vello hood)
Canon EF-S 10-18mm f/4.5-5.6 IS STM..... $299 (plus $25 for Canon Hood EW-73C or $12.50 for Vello hood)

Prices are for new (at B&H). Both the Canon lenses have been around for a while, so it's pretty easy to find nice used ones for a bit less money. They also may show up refurbished at the Canon website (same warranty as new).

The Rokinon has a convex front element that precludes using standard screw-in filters. You may be able to get a specialized clamp on filter holder and square filters for it, but those typically cost around $300 for the holder and a couple filters. In comparison the Canon 10-22mm uses standard 77mm filters, while the 10-18mm uses 67mm.

Note the hoods for the Canon lenses are not included, are sold separately. Because of it's built-in lens hood and convex front element, the Rokinon lens uses a special lens cap. The Canon lenses use standard caps.

If you were using a full frame camera, the Rokinon 10mm lens would be a good choice. But since your 90D is an APS-C camera, either of those Canon ultrawides would likely be a better choice.

I've been using the Canon 10-22mm for a five or six years. It's an excellent ultrawide. Sharp and one of the most flare resistant of all the ultrawides. My only complaint is that the hood is quite large... but I still use it because it works.

I'm not knocking the Rokinon lens. They're quite well made. In fact, I've got a different Rokinon lens that I use on my Canon M5.

You can probably find some reviews of the Rokinon lens on YouTube.

Check out The-Digital-Picture.com for very thorough reviews and extensive testing done with the Canon lenses. Bryan extensively reviews Canon gear, as well as some others. He has done test shots with the Rokinon 10mm, but has not done a full review of it. Plus, the test shots with it were done on a full frame, 50MP 5DS-R... making them somewhat hard to compare to an EF-S lens on an APS-C camera.

From time to time, I take pictures with a Sigma 10-20... set mostly at 12 or 14 mm FL, rarely set at 10 mm.
This lens is used on a APS-C camera...it's quite always sharp...focusing is really not an issue...at f/5.6 You get a lot of DOF.
With FL set at 10 mm (=15 mm FF equivalent), You get wonderful stormy skyes...
or, if the camera is set on the floor, You get an interesting perspective sharp from 20 cm up to infinity without need to close the aperture more than f/8.
Yes, one should own a lens providing 10 mm FL...even if used rarely: it provides ALWAYS astonishing images if You know how to use it (easy to get accoutumed).
Just my opinion.
