@JClavinPhotography At 1.4, 1.8 or 2.0 aperture they dont need to wander out of fucus, a tiny movement either from you or the subject will ruin the picture if your shutter speed is not fast enough and thats a fact.

[JClavinPhotography]

@SuperMangn Your answer doesnt bear any relation to the point I made. ..none at all, and to suggest that a faster shutter speed is desireable with wider apertures so that you or your subject dont wander out of DOF is ridiculous. Its the time between focus lock and shoot that needs keeping to a minimum, not the tiny instance that your shutter is open. You are right that correct shutter speed is vital (subject, situation, camera shake etc) but not so you can better handle shallow DOF.

@JClavinPhotography Ok Mr pro, you forgot to say about needing a faster shutter speed as you go to F 2 in the first place because the DOF is so shallow your focus is off if you or your subject so much as takes a breath. Shutter speed is hell of alot more vital than your assesment.

Guys, you should NEVER use aperture to control light. Aperture is your creative control over depth of field! ..in this video he changed from F/2 to F/7.1, effectively he would be taking a different photograph, the DOF would be so altered. Set your aperture for the DOF you want. Set your shutter speed for a good exposure and leave your ISO at 100, not 400 as he showed. If your shutter speed slows too much so you are beginning to have camera shake, then start increasing ISO, thats what ISO is for!

Does it work for the 20D also?

[bham184]

He probably has a fixed length lens. They can have real wide apertures

[johangunnarsson1]

No, I dont think so?

[mail2kvasanthkumar]

lower aperture can be obtained with different lens, you will not get such a lower aperture on the normal lens

[johangunnarsson1]

Great video. But I am confused about one thing. It seems you have something like a 17-40 or 16-35 lens on? How is it possible for you to be able to chose a 1.8-2.0 aparture when these lenses cant handle those low numbers? Just curious..!
