Usage Of Lens Hoods

Fri Mar 05, 2004 5:14 am

Folks,

Sorry if this is another one of those 'Dumb' questions, but Lens Hoods.... from what I've been able to gather they're good for reducing the incidence of lens flare.

This is all well and good but are there instances when you would not want to have the lens hood on? Do they do anything else other than the lens flare reduction?

Cheers!

they also protect your lens when it's banging into things...
And from dust blowing.

And of course they make your lens look longer which for some people is important  Smile

I never use the lens hood for the 100-400 IS, I find it ridiculous those who use it just to make the lens "bigger". On the other hand, I use it all the time on my Canon 28-135 IS because it seems to be more receptive to flare at 28mm.

You surprise me ... while I agree that obvious flare is not such a problem with 100-400, I do find that in many cases use of the hood on a telephoto gives an increase to contrast and colour saturation. Try some test comparison shots - you might be surprised.

Personally I always use a lens hood - the one exception is if I'm using flash and the hood may cut into the light path

I always use the hood on my 100-400L IS, except in windy conditions. Especially when the wind is coming from the side or front, the giant hood will create lots of turbulences and make the 100-400 handle like a sail boat.

And off course the 100-400L IS doesn't look good without the hood at full stretch! Then it's just screaming for a hood . . . . . .

Photo credit should be mine Harm  Big grin I am the one who took the pic  Big grin

Wietse

ps. always have mine on. A professional photog I know claims it increases contrast.



Now this one should be credited to Miguel Snoep.. Big grin Tim was there as well though..

I'll give it a try to confirm if it gives me more contrast. The reason why I don't use it is because I change position lots of times when shooting planes, have to pack camera in the bag and unpack quite often so I prefer not to use it to avoid having to remove it all the time.

Wieste,

Can you really get that close to the action at AMS? Or is that with ramp access?

I always have my lens hood attached. I guess Canon supplied it with the lens for a reason.  Smile Also keeps raindrops from getting on the glass. Big grin
But like Harm said, it sucks in heavy wind!!! And we sure do have wind in Holland!

Oops, sorry Wietse. Didn't know you took that shot, I robbed it from Tim's profile!

Do we have more action shots of A.net photogs using their 100-400? Seems like AMS is pretty wel covered by the 100-400!

Thanks for calling me king Harm, but I'm really more of a crownprince I would say actually. We do have several kings on this site though Big grin

Actually since I got the 10D I have shot more slides than RAW files, still going strong on K64 Smile

I still have a slide of Miguel and Wietse using their 100-400 sidebyside that I have to scan sometime.

Would be cool if we could all come together and let someone take a shot of us all using our L lenses!

Well that than would than just have to be a Nikon shooter . . . which reminds me of another thread on the 100-400 some time ago, how about aiming all those 100-400's at that Nikon and getting our beams crossed [ghostbusters!]. May the force be with you!

That puppy looks very "not so entertained" about the whole thing  Smile

I have to try and see if it really makes a difference using the hood. Shooting with bright lights or the sun just outside the frame I know it helps, but with the sun directly from behind I didn't think it mattered.

So, how many do we have to cross beams in AMS. From what I know:


  1. Harm

  2. Tim

  3. Wietse

  4. Miguel

  5. Eduard

  6. Me Big grin

Returning ever so slightly to the topic, thanks for all the contributions folks!

I tend to use the lens hood my Sigma 170-500 all the time and based on the comments thus far I shall continue to do so.... and impress passing folks with the sheer length of it!  Wow!

Cheers!

Rez,
I use the lens hood all the time on my 170-500, I got caught in some really bad weather last week and it kept most of the rain off of the front optic. That was until it started to rain horizontally - then I ran for cover..!!  Sad

Ian.

If I could just get the afterburner working...

Yes, I use the lens hood for protecting the front lens/filter from dirt and scratches. Also useful when taking pics on the rain (the water won't get on the lens to blur the images).

I did give it a try, all images bellow are straight out from the D60, using the 100-400 IS. All images are unedited, the only thing I did was resize to 700px and all were shoot in .JPG Large mode.

at 400mm, 1/800, F/8, ISO100, 15h16m26s, NO lens hood:


at 400mm, 1/800, F/8, ISO100, 15h16m47s, WITH lens hood:



at 100mm, 1/400, F/9, ISO100, 15h18m26s, WITH lens hood:


at 100mm, 1/400, F/9, ISO100, 15h18m38s, NO lens hood:


Do you see any difference?


On these last two images, one was with lens hood and the other was without, can you tell me which one had the hood and which one didn't have?

at 100mm, 1/400, F/8, ISO100, 17h52m20s:


at 100mm, 1/400, F/8, ISO100, 17h52m30s:


I admit using the hood as protection for rain but does it really makes a difference in contrast?

The difference in lenshood or not will be easier to notice when you have bright surfaces/objects in the general direction the lens is pointing.
Anything that can reflect light onto the front lens element can cause a reduction in contrast.
The test above doesn't seem to have been shot in the risk zone.

Luis,
I see a difference in the pyramid shaped roofs.
But I think it is even worse if the bright surface/object is closer to the lens than the ocean in these shots.

hmmm I'll have to wait for night time here to carefully look the photos with better light conditions, right now I have a very strong daylight coming from outside which obstructs me from seeing shadow areas.

That's why I only edit photos at night.

Jan, I agree, I do see a difference also, still want to make another "test" closer to a bright plane.

Anyway, for that little difference I prefer to use Photoshop instead of holding a gigantic lens with me.

The hood can certainly help protect an 1800 dollar lens. Id much rather scrape up the hood than the edges of the lens or even the filter. If I dropped it lens first the hood would probably be a save......Artie
