video at 35mm

One of the reasons I had been saving up the money to get an 18-135mm lens is so that I could take videos at a shorter focal length.

I realized that I hadn't taken any videos yet with the lens that I had been gifted, so I went out back and shot a short one at 35mm. This is at 30fps in AV mode with the aperture at 7.1. (I don't know what the shutter speed was).

What do you think of the clarity and colors?

It looks fine to me, but I don't take a lot of video. So I wouldn't know what is best. Maybe you could take the same video with different apertures and see what may be more pleasing to you. I didn't hear any sound, but that's probably because there wasn't any.

Dig,

Thanks. No, there was no sound -- just video.

I realized later that saying this was taken at f/7.1 is a misnomer or erroneous.

I have a T8i, and in my manual, it says that if you take a video in one of the creative modes like Av or TV, the camera behaves as if you are in the P mode; which means that the camera is controlling both the aperture and shutter speed in order to get the best exposure.

I have seen this before as the aperture and shutter speed fluctuate as you shift your camera to various lighting situations - like going from shadow to full light. You can half-press the shutter button and watch the settings bounce all over the place as you move around.

If you are using Auto ISO, it controls the ISO too.

I'm just thinking out loud here, trying to work my way through this.

Mentally, I understand the concept of shooting in Manual Mode and shooting video using a shutter speed of twice your frame rate to produce the most natural looking subject movement (i.e. shooting at 1/60th of a second when using 30fps) and using an ND filter to cut down on the light, but I don't know how you quickly adapt to changing light conditions going from shade to bright sunlight.

I have also read some people who suggest using an aperture of something like f/5.6 to give a smaller depth of field and isolate your subject.

But if you are shooting at 1/60th and at an aperture of f/5.6, you are really going to be flooded with light and risk overexposure. That's what the ND filter is for.

You'd almost have to use Auto ISO and hope your camera can keep up.
