Lens For Videoing Fast Moving Objects?
« on: July 01, 2013, 06:09:51 AM »
Hello everyone, I am an amateur photographer/videographer for the Canon T2i and was wondering what would be a good lens for videoing fast moving objects. I am very fascinated with trains and like taking videos of them, and I think I might try videoing them with my Canon. I just have the two default lenses that come with it was thinking that those might not be the best for videography.

I also live right next to a high speed line where the trains go about 120-135 MPH. So that gives you an idea of how fast they travel.

Thanks!

The advice you need depends more on what the purpose of your video is. You see, if you just take a regular video, it'll probably have motion blur, but that's realistic to the real thing (if you just try to look at it with your eyes). But if you want a video that you can pause and see each frame clearly like a photo then that's a challenge. Or, if you want to do a slow-motion video that's a challenge too for the same reason.

So what do you intend to do with your video and what do you want it to look like? What criteria will you use to judge if your video is successful?

Just wondering cause I don't do video but wouldn't the rolling shutter mess with the fast trains, like I said just curious and don't know because I don't do video.

I would probably rather have it with the motion blur since that is more realistic.  And also it is easier to do it that way.

Thanks!

I think the kit lens would do a pretty good job on this actually. You should manually focus (you have to be aware that focusing won't readjust during filming  - the T2i (or T3i) won't make a good camcorder but the T4i is a bit better). It's probably a good idea to find out how to choose your video settings manually; it defaults to automatic but you can choose manual in the menu. The aperture you want will depend on your scene, and how you want it to look artistically: I would say you'd want wide but not too wide, which is why I think the kit lens will be OK. I would normally say that you'd want your shutter to be about half of the frame rate, e.g. at 30fps choose 1/60th but there might be reasons to vary that. Especially if you feel there's too much motion blur, you might want to shorten the shutter; but of course you might start running out of available light.

Why don't you take an example movie, post it on youtube and link it here - you may get suggestions on how to improve it, and it's easier when you have a base point to start from.

I probably won't be zooming in and out anyways. If I do, I'll just make it two separate clips. I won't be able to make a sample video probably for a while since I am on vacation until the end of the month.

And I have got the manual settings all figured out. I'll use the tips you gave me for the shutter speed, that is a pretty good method, to set the shutter speed half of the frame rate.

Thanks for all of the help AndyCivil. Really appreciate it. I'll post that video next time I get a chance to go out and do some videoing.

Take a look at the Canon 40mm pancake lens.  Its supposedly designed for filming video as well.

You're right, but it also requires the T4i, doesn't it? I mean, they go together to make a more camcorder-like performance.

Yep, just looked that up actually.  With the t4i you get continuous focus in video.
Which this now has me thinking.  I might want to upgrade to the t4i as my second camera as I'm getting more and more requests for videos of the races.  Its had doing manual focus of things going 100mph.

Read about the new 70D, it should blow the t4i out of the water for video features and might resolve better too.

I did a few Google Searches and found that this lens was great for videoing and is compatible with the T2i.
http://www.amazon.com/Canon-50mm-1-8-Camera-Lens/dp/B00007E7JU

It is also pretty cheap, only 90.00 bucks and lots of very good reviews on it. Do you guys think it is a good buy?

Yes it is. Can't go wrong with the nifty fifty. I have the same lens and love it. Don't use it very much but still love it and best buy for the money.

The 50mm ƒ1.8 is a must-have lens just because it's the best affordable way to experiment with a very large aperture. It makes a great portrait lens!

To use it for video, you'll have to work with the limitations. There's no zooming and no image stabilisation! It will get you a lot of light, which will allow you to either capture sharp images of moving things (if that's what you had wanted) or viewable movies of night scenes; things that would be hard otherwise.

I'm going to attach a comparison movie I made using the three cheap lenses of an intersection at night; skip to the 1:00 mark to skip over the HX5 stuff.
