No experience with the 85 but I have the 14 and it's amazing! Just starting out I would think the Canon 85/1.8 would be a better deal, it's plenty sharp and has great AF. I loved mine when I had it and it will most likely be my next lens.


I like to shoot things...sometimes with a camera!

I own the Canon 85mm f1.8 and it is indeed a great lens. However, based on the images I see I still have an interest in picking up the Rokinon 85mm f1.4 - it just renders in a way that I'm really drawn to. I also own the Rokinon 35mm f1.4 which is a stellar lens and my favourite of all the lenses I own. For the OP's purposes though, I would go with the Canon 85mm f1.8 - the reason being that there isn't that much of a price difference between the Canon and Rokinon 85mm lenses and AF, especially the fast USM AF on the Canon, makes the Canon lens more versatile in my opinion. If the decision was between Canon or Rokinon 35mm lenses, I'd pick the Rokinon 35mm over either of the Canon 35mm lenses (based on IQ vs. price) despite the fact that its MF.

I read a lot of posts about taking photos of "moving kids". But in reality, I don't see many photos of kids moving, running, etc. The great majority of kid shots are kids posing in one way or another. I've taken maybe 250 to 300 photos of kids from age 3 thru 7 and about 15 are action or moving shots, and maybe half of those are kids on a swing. I think you have to ask yourself if the intention is to actually take photos of kids in action or will you be posing them like the majority of people.

True but modern cameras also do not have the same kind of focusing screens that made MF much easier when MF lenses ruled the world.

agreed.

Changing the cameras focusing screen with one that is made for MF will correct this

agreed.

but may also screw with focus on any AF lenses.

disagreed.

Get the canon 85 1.8 if you're photographing kids. MF is not easy with moving subjects, though it can be done with enough practice.

This. The 85 1.8 is a crazy good lens for the price.

Agreed.
I switched my 60D screen to the EF-S Matte screen and couldn't be happier. No effect on AF but makes a world of difference on MF.

Optically the Rokinon lenses are extremely good. The 85 is sharp wide open and very inexpensive.

I have photographed a kid on a swing using the Rokinon. Yes, it takes a little work. Yes, every photo was not in focus, but I took a bunch and some were. No, even an AF lens would have had trouble getting every shot in focus.

So, it takes a little more work and thought, and you want to take 5 shots to make sure at least 1 is in focus (not a problem with digital). Overall, the extra thought I find translates to better pictures versus just point and shoot autofocus. With that said, the 85 f1.8 is also a great lens.

The "problem" with the Rokinon lenses is not really that they are manual focus. Heck, I shot with manual focus lenses for 20 years (AF is way faster and more accurate than I ever was). It's doable, though other responses are correct that it's made more difficult with the modern DSLR which is designed for AF and not very manual focus friendly. Manual focus is hardest with models like the OP's T3i (600D), a cropper using a penta-mirror instead of a pentrism, and without an easily interchangeable focus screen. There are no Canon screens for it... Third party screens are available but are expensive and not easily installed... They'll help with manual focus, but most types will make spot metering unusable (does T3i even have spot metering? I dunno). Live view will work, too... if possible to use it.

At any rate, manual focus is possible and not all that big a deal.

IMO a much bigger deal is the Rokinon lens' manual aperture.

That means slower shooting, stopping the lens down manually just prior to each shot and opening it back up to manually focus (viewfinder will dim down whenever you stop the lens down). These lenses also aren't chipped, so Focus Confirmation won't work. Zeiss ZE and Canon manual focus lenses (the four TS-Es, for example), have electronically controlled apertures that are set via the camera body, so maintain wide open aperture until the moment of exposure, when they instantly stop down to whatever was aperture value was pre-set. They also provide Focus Confirmation.

There are chips that can be bought and installed on the Rokinon lenses (which also are sold under Samyang, Vivitar, Bower, ProOptic and some other brand names), to allow Focus Confirmation to work... But it fails once the lens is stopped down (might work to f8 or f11 in good light, depending upon camera).

For 85mm, like others here I'd definitely recommend the Canon 85/1.8 instead (in fact I have it and use it).... or the Sigma 85/1.4.

I'm considering the Samyang/Rokinon 14mm, since I'd generally be using that for much slower types of shooting where the manual focus/manual aperture wouldn't be a significant issue.

Forgot about the Sigma 85. If OP has the funds, that would be something to really look into. It's a great lens from what I've seen and read about it.

i agree with the above statements, i have he 14 f/2.8 and it is an amazing lens especially for the price, the only caveat for the 14 mm is the barrel distortion you get with an ultra wide lens, but it is super sharp and has excellent color / contrast.

IMO a much bigger deal is the Rokinon lens' manual aperture.

I agree that manual aperture does slow things down a bit, but generally I tend to shoot my primes near their maximum aperture anyway as, for me, the shallow depth of field and/or low light capability is the reason I purchased a wide aperture prime in the first place. If I'm doing any shooting at f8 for example, its typically landscape photography and slowing things down in that scenario is rarely an issue. At f4 or wider I don't bother focusing with the lens wide open - I find the viewfinder bright enough to still focus accurately, though I'm using a 5DII (a penta-mirror camera with a smaller viewfinder may be more of a challenge).

certainly you don't have to do that on every shot: you could easily walk around all day with the aperture clamped down and just deal with a dimmer viewfinder.

i mean, what did people with "slower" manual focus lenses do in the past?

There are chips that can be bought and installed on the Rokinon lenses (which also are sold under Samyang, Vivitar, Bower, ProOptic and some other brand names), to allow Focus Confirmation to work... But it fails once the lens is stopped down (might work to f8 or f11 in good light, depending upon camera).

heh.. manual focus at f/8 or f/11? why bother! DOF and focus scales to the rescue. :)

more seriously, maybe in a macro situation, but that's the only one i can think of, and only because the subject distance is so close the DOF remains relatively thin.

certainly MF and MA aren't for everyone, but that just means there's a robust used market for these lenses so you can pick one up cheap, and unload it for zero loss if it doesn't work out.
