If I would buy the Rokinon 50mm f/1.4 and shot my 2 year old running around it would be pretty darn difficult to get him in focus while he is moving, right? Anyone have any experience?

With a manual focus lens I wouldn't bother trying to refocus constantly. You'l probably have much better success 'zone focusing' a la street photography. Basically you pre-focus your lens to give you an area or 'zone' of sharp focus. You can snap shots when the subject is in this 'zone'. You can Google the technique. There are some good articles on the subject out there. Here is one I picked kind of randomly:

Trying to get someone moving while manually focusing is exceedingly difficult. In addition to the zone method mentioned above, shooting a burst helps as well. Then look for the image where the subject is best in the zone.

Of course, if rapidly moving subjects is your goal, you might invest instead in a lens capable of auto-focusing. So much easier and you'll get better results. There are quite a few very decent 50mm lenses out there AF capable.

Yup, I'd think about trying to save up a bit more and grab the Sigma 50/1.4 (non-Art). AF may be flaky, but you'd probably get more keepers anyway. A lot more. "Zone" focus would be rough wide-open at 1.4 (that link talks about stopping down to f/8). Were you intending to use it wide-open for indoor work, without flash?

I'll wait for the new 50 f/1.8 STM

it's because of the focus screen on a dslr is pretty much junk for manual focusing.

an EVF is much better in that regard, however an autofocus lens is an easier solution.

Heya,

I only use manual focus when I'm chasing my kid around (17 month old). I can focus more accurately and faster while composing just right with a manual lens, where as with autofocus, I'm always having to watch what focus point is in use, and compositions are harder to get right without fiddling with the autofocus point in use which takes away from shooting time. Also in low light, I can nail focus in doors where as with an autofocus lens, if it hunts, I'm losing a shot. So I tend to use a lot of manual glass for portrait and just playing with my kid in general. And I'm doing it all at F1.4 to F2, max, with manual glass. Typically using a 50 F1.4 (super takumar), 58 F2 (Helios 44-2) and 85 F1.4 (Samyang), with an old 5D with an EE-S screen for optimal viewfinder manual focus precision.

Here's just from this morning, took the kid out to play with the flowers and grass and the yard lion (cat) to wear her down for an afternoon nap, shot with a Helios 44-2 and 5D, all manual.

Some other little fun times with the squirt (again, Helios 44-2 or the Samyang 85 F1.4, all manual glass):

-- I have the 50 F1.8 II, 40 F2.8, etc, the cheap fast primes, and they're just not great. The 50 F1.8 focuses so slow, and grinds around, and I find it just too slow to keep up with the squirt. Part of that is probably me, because I'm simply faster with manual glass with longer precise focus throw. Plus I can compose freely while doing it. With an AF lens, I have to frame looser and have to keep the AF points either on center, or all, depending on the situation and hope it nails focus while I snap moments. When it comes to kids, micro-expression and moments, last for less than a second, and when the lens is off or hunting or composition is all wonky trying to keep the focus right, it can be aggravating.

-- With your camera, with a precision matte screen, you can totally use fast manual focus lenses. And then you can play with vintage glass that is still very relevant today, or very good (rival L quality) modern manual glass, like the stuff Rok/Samyang/etc are pumping out.

I would give it a try. You may like the freedom of composition while focusing.

I find there's little issue with keeping up with a fast moving kid and getting that "moment" without worrying about the comp & focus being all buggered up, waiting on a slow lens like the 50 F1.8 II as it grind-jumps around trying to keep focus with Servo, using center point most likely (just to ensure focus on a face, which is typical, which also means a lot looser compositions to keep hands and stuff in the frame).

Very best,

Just a quick question, of the current new MF fast primes how many have an automatic aperture? Or are they all pre-set lenses? I have a feeling the Zeiss ZE's have an electronic aperture control, but not the others. I guess I have been lucky that even the very basic 1960's vintage Praktica Nova b that I learn't the basics with had automatic stop down with it's M42 mount. An auto aperture makes MF so much easier if you are having to shoot at anything other than wide open. Especially with the Split Image/Fresnel focusing screen that were also common. Even at f/4 they can start to black out. As I understand it the High Precision screen Canon offers is designed to be used at f2.8 or wider, and gets quite dark after that.

Heya,

Very best,

Cute kid! And I love "yard lion"; I'll have to remember that. :)

If this is your first experience manual focusing, its going to be really hard. Can it be done? Sure, especially with a lots and lots of practice, but there's a reason why the kids in MalVeauXs photos and online samples from both the 50mm and 85mm lenses are stationary or not moving quickly...

I would guess that upon getting the lens, you will marvel at the shots wide open with the narrow DOF and the bokeh. Once you start trying to catch your kid moving (who will only move faster as they get older), you will realize how frustrating it is, especially the dismal keeper rate and how many times you "missed" the shot. At some point you will want to sell/return/trade, use it more for video work, and/or pick up an AFing lens. Can you really afford the months/years that it will take to develop the necessary skill level? Are you ok with missing those shots during time period in your kids life, he's only 2 once?

If you are considering this lens primarily because of its price/optics ratio and are actually considering it for action shots, save up some more and get a lens appropriate for the job at hand.

If you are looking for a nice portrait lens for your crop camera in more controlled situations, go for it.

The Canon mount Voigtlanders also have electronic apertures.
