best canon lens t3i image
Justyn Bel
I have a Canon t3i, and i want to do a slow mo sequence in one of my films, so i was trying to put the shutter speed at 1/4000 with the frame rate at 60, but the screen gets really black even when the iso & f-stop are all the way up. So unless it's like super super bright outside i dont know how to get this to work with a 4000 shutter speed. Is there a trick for this?
Answer
It's not surprising it's black with such a fast shutter speed. Unless you are in stonkingly bright conditions, it's bound to be.
When you say the aperture is all the way up - are you aware that the widest apertures have the lowest f number? You could buy a faster lens (one capapble of a wider aperture, say f1.8). Or you could buy some high intensity lighting to light whatever it is you are shooting.
It's no trick - its about learning to balance the three parameters of the exposure triangle (ISO, aperture & shutter speed) for the lighting conditions to get a decent exposure.

Is there a canon lens that will autofocus without the lens moving and without having to press shutter?

I have a t3i. I want a lens that will autofocus, however, I don't want to press the shutter, and I want it to focus like your standard video camera. Yknow, the cameras with the built in lens that autofocus on the inside all by itself, completely silent. Is there a lens for the t3i like that?
Answer
Part of the issue is the lens. Part of the issue is the location of the mic in the camera. Because low-end dSLRs are designed to capture still images and video (and audio) is a secondary "convenience feature", the location of the built-in mic and lack of internal audio dampening causes the built-in mic to record the motors moving the lens when auto-focus is used. The manual
http://gdlp01.c-wss.com/gds/0/0300004720/02/eosrt3i-eos600d-im2-c-en.pdf
even says so. See page 163.
You have a couple of options for resolution:
1) Use an external mic.
2) Use an external recorder and synch the audio when editing.
"Your standard video camera" is designed to capture video - and audio. The mics are better isolated form the camcorder body. It isn't that the lens focus mechanism is "completely silent"... the lens moves and makes noise, but because the camcorder is designed to capture video and audio, the design of the mic installation is very different.
Since we're here, you probably should read up on the overheating and file length limitation of your camera. You will find the same information in the manual for the T4i - and pretty much any dSLR designed to capture stills.
If the large sensor or other specific dSLR feature is required, then use of a device designed to capture video is much more appropriate. The Blackmagic Design Cinema Cam, Canon EOS (C100/C300/C500) Cinema Cam series, Sony NEX-VG series and NEX-EA series or the Panasonic AG-AF series are essentially dSLRs designed to capture video.
