« on: June 12, 2015, 05:10:36 PM »
Tomorrow, saturday, I have to film with my mark5dIII at night in and around a house. I've got three lenses:
16-35 f/4 IS
24-70 2.8 II
70-200 2.8 II IS
Filming will be handheld.
Which lens do you recommend?
Thanks!!!

Thanks for your reply.
It's a film for a musical and I will film children standing in front of a house in the dark (half) and inside the house (room).
We will wake some colleagues for "fun" and we will interview them. It's all about fun, but I've got just one chance.

Your f/2.8 lenses will do better in low light.  The 24-70 would probably be the most useful focal length for groups.  The 70-200 will be great if you have plenty of room, its image stabilization will help you shoot stationary subjects at slower than 1/focal length shutter speeds.

Using the 24-70 will be tough due to lack of IS.

Using the 16-35 may be a challenge due to the modest aperture.

But at the end of the day, shouldn't you pick the lens based on the composition of the shot? If you need a group shot without perspective compression, the 70-200 won't help you at all, and if you need a close-up with a defocused background, the 16-35 won't do what you need.

Don't put the cart before the horse, basically.

The 24- 70 should work fine.  I read this as you making a video, some sound like they think its still photos.

You should be clear, so you get applicable advice.


Handheld video is very difficult, it can be shaky and boring.  Mount the camera on a tripod, or even sit it on a stack of boxes or other support if you can.  A monopod is another option.  You also have to manually focus.

You cannot zoom the lens and expect it to stay in focus, lenses are not parfocal until you get into the $40,000 range. Zooming a perfectly focus lens will result in out of focus children.  If you are close to your subjects, using a wide aperture means a shallow depth of field, and some of the children will potentially be out of focus.  Figure out your focal length and distance in advance, that will help you decide the aperture and ISO you will need.

I would plan out your shots, measure the distances from the subjects and the lens focal length required.    Then try to determine the amount of light, and see if you can set the lens at f/4 and ISO 3200 or less.  If that works, then you can use any of the lenses.  At f/4 and 6 ft from your subject with your lens set to 35mm, you will have just over 2 ft depth of field.  1.28 beyond the focus point and 0.9 ft in front of it.  At f/2.8, the depth of field will be much less.

Work all the things out in advance, and put down some masking tape or other marker on the floor or ground there you want them to stand.  Same with the camera.  If you just expect to walk up and start shooting, and you don't have a 2nd chance, you need to control as many factors as you possibly can, and have a idea for plan b if that doesn't work out.

Post more information are you doing video?  I took the word filming to mean video, but its not certain.

Thank all for your comments. I did my job last saturdaynight and I am satisfied with the result. I have used the 24-70 2.8 and a tripod. Thanks for the tip. I wasn't planning to do so, but it helped a lot.
Because of children in the video, I am not allowed to show the result.
Thanks again!!
