Lens Hoods??

Forgive me if this has been asked, but I couldn't find it. I guess I didn't realize the importance of lens hoods, and haven't been using the one that came with my camera. I've been reading about them, and some say that the lens hood that comes with the lenses that while better than nothing, isn't really sufficient.

When would you not use one? How do I know what lens hood to use so as to not create vignetting?

Thanks!

I've always just used the hood that came with my lens. I was at a lighting seminar with Joe McNally a while back and he just used his hand. Go figure.

Hmm, interesting. Thanks.

What the lens hood does is stop any extranious light from entering the side of the lens, making for a better photo. Check Wikipedia/lenshoods for a more detailed explanation.

Thanks, I did actually look it up on wiki lol. I suppose it's a so often used piece of equipment that not many mention it, so I hadn't given it any thought and wondered because I'd not heard them mentioned.

Some photogs (like Scott Kelby and Joe McNally) always recommend using a lens hood. If nothing else, it helps protect your lens from getting banged around and scratched while in transit.

I actually don't think I've ever shot with my 18-105mm lens without the hood attached.

Use the lens hood all the time. Not only does it keep out extraneous unwanted light it's also good damage protection for the lens.

I suppose I'd better put it on next time then! LOL Wish I"d known that. Sun was pretty bright the other morning, even at 9-10 am.

I just use the hood that came with the lens and a little hand if needed, crop it out later.

Use the hood that came with the lens. That is the one designed to do the job for that lens. You won't need to use your hand at all.

Many a time when taking a shot into the light with a lens hood in place I can still get a flare or spot, holding my hand above the lens can reduce or eliminate the problem. I was joking about the crop, seldom happens.

I use one all the time; I have used the rubber retractable type, clamp type, etc.
I find the petal type to be best for me, I just turn it around when not using it, or when its pack in my camera bag. As others have mentioned it does protect your lens while you are walking about with your camera over your shoulder, if in case you should bang it against an object (better you break a lens hood then a lens). Keep stray light from entering your shot.
If you lost yours, or didn't get one with your lens. You can get one really cheap through Link Delight, I perfer the petal type myself.
