doesnt strobe effect lighting help with a camera's focus. Like an AF assist method?

coz the built-in flash can fire bursts of light, to help the focus pinpoint the point of focus, right? smile.gif


Haha - for some weird reason, I hate when it does this! My 430ex doesn't do this, but my built in flash does this, and it's quite annoying when it flashes several times to focus the pinpoint. So it's like I want to try and take a picture of people, and here are a 100 more flashes to go with it before I take the picture; not cool in my eyes - lol.

I just realized the 28mm I was telling you about a while back is actually a wide angle lol.

I didn't notice until I was comparing with my other lenses.

Built in flashes use flash as af assistant when in use, but most good flashes have af assistant that focuses with infrared beam instead of flashing the strobe. With those auto settings the strobe makes lower first flash that it uses to calculate the right light power, if i remember right.

uh ok now I am even more confused. So a camera flash is a strobe but there are strobes that could flash continuously?
Well stop calling camera flashes strobes ffs! lol It's a freaking flash not a stupid strobe besides strobe is such an ugly name tongue.gif


I think those lights in studio that are allways on are just called studio lights, not strobes.

with 1.6crop factor, like on 450d the 28mm is called wide angle, because its wide on full frame sensor or film, about 50mm on film is same as 28mm on that crop factor and 50mm is called a normal lens(most old film cameras without zoom lens are with 50mm lens). So 28mm is more like normal lens with 1.6 crop camera, even tho its called a wide angle.

im pretty stoned so i hope im making sense

Yeah, I remember seeing the red light on my flash, it's pretty bright, but it's less annoying - biggrin.gif
