Hi, all.
Can anyone tell me the benifits of using a lens hood? I have a canon 400d.
Cheers.
 
Well, the lenshood has nothing to do with the body! They are lens specific, (normally) and keep stray light (lens flare) out of the front of the lens, especially on bright, sunny days!
 
Protecting the lens is what I use them for. We dont get enought sun to worry about lens flare:lol:
 
just in case you drop it.... :'(

Side light effecting exposure...

:thumbs:
 
I always use a lens hood for the specific lens I'm using. There are odd occasions when it gets in the way and it's better not to use one (possibly macro photography when you're really close). But 99% of the time they can only benefit the pic. even indoors.
 
They help me stop anything or anyone touching my front element and are really handy when changing lenses.
 
I have a lens hood too. I hardly use it, should I start using it?
 
also good if you are shooting when it's slightly raining, stops drop getting on the lens

Yep, I found mine very useful when capturing lightning over my apartment in India! Unfortunately though, there's only so much rain it can protect you from :lol:
 
Result, i was going to ask a similar question but cam upon this thread with the good old search function :).

Might as well ask a stupid question anyway though while i'm here......do you use them on all shots or are they more benefcial for wide angle or zoomed in shots? I've just discovered the hood that came "free" with my 24-105 F4L also fits my 10-22 so was going to stick it on this when i'm using it if wide angle shots would benefit from the hood? I have to say i've never used one before despite having several that have come with the various lenses i've bought!! :shrug:
 
only use the hood that comes with the lens,as they are for that focal range, the wide angle lens has a tulip hood so as to stop vignetting .
If you use it on the 10-20 you will probably see a dark circle (vignneting)around the pic.

Mind you, this can look cool sometimes.

Damn, thought i was on to a winner there!! lol :D. Thanks for telling me this as i hadn't really thought about it although the hood comming with my 70-200 is considerably larger then the one for my 24-105 so i really should have guessed...... :shake:

The hoods have very similar numbers, the one that came with my 24-105 is a Canon EW-83H and the one recommended for the 10-22 is a Canon EW-83E.......I'm going to assume there is a big difference between the "H" and the "E"
 
Oh, something else just come to mind.......Wontolla mentioned it doesn't have anything to do with the body which lens hood you use but toweshot has mentioned it's to do with the focal length of the lens.....

So, does it make a difference if your using full frame or a crop sensor camera as surely the focal lengths are in reality different? Or is it not THAT much of a difference it makes any odds? I'm going to assue hoods that come with the lesnes are designed with full frame in mind?

Yes there is. Here's a quick guide to Canon lens hood nomenclature.

The "EW" stands for wide angle, which tells you that the hood is designed to fit a wide angle lens. "ES" denotes a hood desgned for a standard lens, and "ET" a hood for a telephoto lens.

The "83" refers to the internal diameter of the hood (ie the diameter of the end of the lens) in mm, which is why the EW-83H appears to fit the 10-22 as well as the 24-105.

The letters on the end don't mean anything though. They don't help you work out which lens a hood fits.

The reason you have specific hoods for specific lenses is because of the different angles of view you get. Hoods are generally designed to cut out as much stray light as possible, without getting in the way. For a very wide angle lens, the angle of view is very wide so the hood has to be shallow. For a longer lens, the angle of view is narrower and so the hood can be deeper.
 
only time not to use the lens hood is with the inbuilt flash, when using a flash take it off.

Might I refer you to my thread, where half the replies I got were simply to take the **** out of me or ridicule the question.

Actually; better not.

I don't see much point in a LH either. They're clunky, get in the way of filters, and if you drop your lens from such a height as to *need* an LH to protect it, you should be more careful...

It really does not make any difference! As I already mentioned, the lens hood has nothing to do with which body you use. It is made to fit the lens only. Providing the lens fits your body, then all will be ok!
I disagree with some of the others saying they are not needed, not only does it prevent stray light from the sides, it does act as a protection for the lens/filter! I had my camera with 55-250mm IS attached around my neck last week, spotted a Tawny Owl in the distance, put my Binocs to my eyes to folllow it, walked forward a step or two and my LENS HOOD whacked straight into a drystone wall! If I hadn't had my lens hood on (no filter) I would now be buying a new lens!
Also saying that you should take off the hood when using flash only makes sense when doing close up (macro) shots.

LOL, I have no problem if half the people were to take the ***** out of me so longs as the other half were actually giving useful advice which it looks like i seem to be getting :)

Again, thanks for all the info and appreciate people taking the time to answer what to most is an obvious question but obviously to me it's not. Like anything, it's only obvious if you know the answer :D
 
one other use of a lens hood - this time the soft rubber ones that fit to the filter threads, is for when you have to shoot though glass (eg from one of the London eye cabins, or out of a tall building). You can "squidge" the lens hood onto the glass and cut down/out any stray reflections.
 
All questions are new to someone,please guys new and old,ask away because someone will try and answer it.
I know i have picked up tips while looking at these posts and I'm sure thats true of others as well.

So not only the OP will gain from these answers.:thumbs:

THERE IS NO SUCH THING AS A DUMB QUESTION.;)
 
I always shoot with a lens hood. Never leave home without it.:):)
