Lens hood for camera?

kay

I have a cyber-shot camera, and it came with a lens hood. And I have no idea what the lens hood is for. I know how to put it on and everything, i just dont know what it helps or what it does.

Does anyone know?

Thanks much!!

Answer
While it does protect your lens as the other person said it main purpose is to reduce flair and glare from the sun. If shooting outdoors you should leave it on.

Where to find a quality camera lens hood?

Madison

Such as the one in this video at 1:26

http://www.youtube.com/watch?v=1tJKP6hc-R4

It's a Nikon d3000.

I'm looking for all different kinds of lens hoods.

And I'm currently using a AF-S Nikkor 18-55mm 1:3.5-5.6G lens on it.

Links please :)

Answer
Here's the one made by Nikon for your lens:

It's not real long like the one in the video, because that was a "telephoto-only" lens. You can't use a long lens hood on a lens that zooms out as wide as 18mm or it will cut off the corners of your image.

what is the point of a camera lens hood?

Nicole

I've been looking up accessories for my Canon t4i and came across lens hoods and was wondering what their purpose was and they also come in many different lengths

Answer
Well there are two types of hoods, Petal Shape and Round Shape. Both do the same job block light from the sides where you don't get things in frame even if fully zoomed out. And most lenses.. hell very few do 180 degrees this means that light hitting the lens from the sight can get in the way of the actual light you want to capture.

In short look before you notice that left and right of your viewcone you see things but they are unsharp. That is your perifical view. In a lens for a camera you don't want that. Now what if I shine from your perifical view are a big 500Watt building light in your eyes... yeah you don't like that.

See with lenses you want only light from the area you want to capture. The rest.. is just in the way. A lenshood blocks light from coming from those area. Less light from the side means no false light. meaning more contrast. Think of it of you putting on horse caps that block your side view. Or wearing special glasses with side blockers. Maybe ski glasses.. suddenly me shining a 500Watt building light has no effect .

And that is what they do.. block light from the sides that might and do effect image quality.

Round lens hoods are simple, as in they tend to come with lenses that rotate the front as they focus. See every camera has a certain size of "frame" the sensor. And what lens hoods have to do is block all light coming from angles.. outside the lens view based upon that frame size.

Now rotation fronts mean that they have to use round ones. More expensive lenses have non rotating fronts. This means that they also can take in that the framing. For instance 3:2 means that one side of the frame is longer then the other. And petal shaped hoods make it so that the top and bottom will have longer flaps. While the sides have shorter flaps. This way they block out as much light from the sides you won't want.

In the end you get more contrast, less stray light, and no nasty side effects.

I fear though .. well a reality is that the kitlens tends to come with a WORTHLESS hood. That tiny miniskirt you can buy for your 18-55mm is worthless. Now the 55-200mm's hood is actually useful.But the 18-55mm's tiny skirt is a joke. So you don't need that particular one.

If you buy a more expensive lens with a non rotating front you'll get the petal shaped hood. And trust me you will want to use those.

Where do you buy Lens hood for a camera?

Q. Im not talking about the small lens hood for DSLR cameras ether. Im talking about the BIG lens hood like what some Sony, Panasonic or Canon cameras have.

And if you want a better picture, panavision has some examples of lens hoods here; https://www.google.com/search?q=panavision&hl=en&tbm=isch&tbo=u&source=univ&sa=X&ei=sDg9UdPdDNCFyQGguYDICQ&sqi=2&ved=0CFcQsAQ&biw=1600&bih=744

What site and or place sells the Big lens hood for cameras? Or can you only get these lens hood strictly if you buy the camera as well (or if the lens hood only comes on a certain camera?)

It would be helpful

Answer
Lens hoods are either small or large based upon the focal length of the lenses NOT the brand.

The link you gave us show what are called a matte box. They can be adjusted as necessary to produce the best protection from stray light causing lens flare. Unless you are planning on shooting with a 35 mm ARRI and zoom lens, you don't need one

Lens Hood? Olympus?

Bex

I've got a new olympus camera (my first 'fancy' one ever) and we got two lens hoods with it. one say Lens hood LH-61C and and the other says Lens hood LH-61D.
I have a faint idea (blocking out the sun so it doesn't hit the lens) but what exactly are they for and what kind of photography are they for?

Answer
Lens hoods can be used in all photography and accomplish two tasks. Foremost, they block unwanted light from entering the lens -- light that would not be in the regular field of view of the picture. Blocking this light reduces "lens flare" and can help provide you with better color saturation for your pictures (less color washout effect). While that's most beneficial in bright light situations they can also help in low-light where there are other bright sources (imagine a cell phone open during a movie).

Second, they help protect the lens from damage. It's harder to hit the surface of the lens, and it can help keep off dust and moisture.

The 61C is for your 14-42 lens and should be flower petal shaped. The 61D is for your 40-150 lens and should be cone shaped.

what is a lens hood ( for cameras?)?

what do you use a lens hood for on a camera ?
why would i need one?

Answer
It prevents stray light that may enter from an angle to the front of the lens from degrading images by ghosting and lens flare.

The flare that can result in "artistic" aiming the lens toward the a light source is intentional and can be quite creative, but the other should be avoided.

Lens hoods can be the first line of defense when shooting under conditions where the lens may be damaged by flying bodies or other objects (sports and off-road shooting for instance).

Here is the result of such an uncontrolled event. Not only was the lens hood damaged, the UV filter was too.

What is the use of camera lens adapters?

best camera lens hood image

Quizzing

Can anyone please tell me the use of Camera Lens Adapters. What is the importance of having it or not having it?
I am thinking of buying a Canon S3 IS. I am not willing to buy a SLR as I am new to photography. I am thinking of taking photography as a hobby. So, when I went through Canon website I came across this term Camera lens adapter. So, that's the reason why I put up the question in Yahoo Answers.

Answer
I've had the Canon S3is for about 8 months. Love It!

So far, I haven't found a need for the adapters. But, basically, Canon offers a couple of configurations - a barrel type adapter that attaches over the main lens, and onto which you can mount either a wide or tele lens. I THINK there are two different adapters - one for each setup.

If you are going to shoot a lot of wide angle, you might choose the wide angle converter option. This is one area where the S3 is lacking. It's widest normal view is equivalent to about 35mm, which isn't REALLY very wide.

In my experience, the 12x tele in it's original configuation is so good, I doubt that I'd ever want to add a tele converter!

One other possible advantage of using an adapter is that you can add filters or a lens hood.

I strongly recommend that - if you by the S3, and if you want to add adapters, lenses, etc. - buy the Canon brand accessories. Yes, they're more expensive. But, believe me, this in one area where you really do get what you pay for.

And a crappy accessory lens that distorts and has lousy color rendition in NEVER a good buy!

Chck out the Canon website for details ... or DPReview.

Would it be unwise to use a 58mm flower lens hood made for a different lens on my 58mm lens?

Adam

I greatly prefer the styling of the flower lens hoods over the less appealing, generic ones. Seeing that the 58mm lens hoods should fit any 58mm lens, would I be making a mistake picking a lens hood not made for my lens specifically?

Answer
There are two issues with lens hoods.

The first you know about - they must attach to the lens. Any 58mm hood will attach to any lens with a 58mm front diameter.

The second has to do with the focal length that the hood is designed to work with. If your lens has a wider focal length than the hood was designed to work with, you may experience vignetting - darkening of the corners and potentially the edges of the frame.

If your lens has a longer focal length than the hood was designed to work with, the hood will be less effective in controlling stray light entering your lens.

Segmented hoods, sometimes called 'flower' or 'petal' hoods, have four segments rather than one continuous ring. The idea behind them is that if you align the hood with the image frame of the camera, the gaps in the hood will line up with the corners of the frame - the areas where vignetting is most likely to occur. That minimizes the risk of vignetting while allowing the hood to be deeper and therefore more effective in controlling stray light.

The problem with segmented hoods is that to work, the segments must always line up with the edges of the image frame. The design of some lenses results in a rotating front element - that is, as the lens focuses, the front element rotates. If you try to use a segmented hood with a lens that has a rotating front element, you will constantly have to realign the hood because it will rotate as the lens focus changes.

So the bottom line is that if the front element of your lens rotates as the lens focuses, you cannot use a segmented hood.
