17-40L hood

[EiRiK]

does the hood included for the 17-40mm L serve its purpose?
any big difference with and without it on?

thanks

yes, it occupies so much more space in my backpack with the hood on

i believe the hood should reduce the amount of flare, never really test out the different cos i just leave the hood on

Dun have the 17-40 but generally it's advisable to use hoods with wide-angle lenses to reduce glare.

The hood for the 100mm macro usm is also very big and took up so much space

100mm macro usm hood big? Then what about those of the long tele? Keep the hood on, it reduce glare and protect the glass.

ic... i know that it is advisable to always keep lens hood on...

just that the hood of the 17-40 looks really weird (very wide and very short)..

anyway, thanks for the info dudes

tim, you mean those nice white hoods for the canon big mamas of 300 f/2.8 and longer?

the lens hoods, if you have it for the wide angle lens, will really um... shine when you try them in darkness - you can see from my shots below:


Shot 1: ISO100, 5 sec, f/3.5


Shot 2: ISO100, 15 sec, f/5.6, hand shielding as "hood"


Shot 3: ISO100, 15 sec, f/8, hand shielding + smaller aperture

As you can see, the first picture really "kenna" from no hood, and I shot it at 24mm wide. Remembering this was shot using DSLR 1.6x crop ==> 36mm FOV, imagine how bad it could have been if it was on a full 24mm FOV! Hence I would highly suggest using a hood in such a situation... Looking at the 2nd and 3rd shot, though there was some "improvement", but you can still easily see the flare of the streetlamp near the top of the image. But see how much hand shielding helped compared to the first pic...
