A Question on my New Canon EF 100-400L IS USM II Lens
Jul 29, 2018 14:39:59 #
I finally saved up enough $$$ for a new EF Canon 100-400L IS USM II lens which arrived yesterday (going out tomorrow to the Rocky Mountain Arsenal Wildlife Preserve to put it through it's paces), and have probably what is a dumb question. When attaching the lens hood there is a sliding door approximately one inch by one inch when in the retracted position. I have been through the instructions, however they are generic for all EF lenses and have never seen such a door on any hood. So, what the heck is the sliding door for?

Could it be an opening in the hood so that you can rotate a CP without taking the hood off?

Interested in this lens too, so searched the slot's purpose.
ET-83D lens hood, that features a cleverly placed and convenient side window allowing the user to easily adjust specialty filters while the lens hood remains in place

Maybe if all the stock Ef and Ef-S hoods had one they'd be worth the price. just saying.
It sounds like a nice feature really meeting a need. Especially considering how deep that lens' hood has to be.

Ah, simple explanation and certainly makes sense. I don't use filters too often but when I do that does indeed sound handy!
Thanks guys;

It's for CPO filters, so you can adjust them with the hood in place (Pentax is been doing this for the last 40 years)!

That is so you can reach in and rub your finger on the front element of the lens. (No - just kidding..... it is for adjusting a polarizing front filter withut having to remove the hood, as others have said).

that is why I favor the screw on hoods that resemble toilet gaskets they make filter adjustment simple just rotate the hood

That is a wonderful lens. A friend uses one on her crop camera and takes fantastic wildlife photos.

If you put a filter on the lens that you can rotate, this little sliding window will allow your finder to reach the filter when the hood is on the lens.

Yeah, too bad those rubber hoods are so lousy at the other functions of a lens hood, such as shading the lens from oblique light or protecting the front element from bumps.

Well, since it's an L-series, the hood is included with the lens.
Just don't break it or lose it... a replacement hood costs $70! (https://www.bhphotovideo.com/c/product/1092636-REG/canon_9533b001_et_83d_lens_hood.html)
No doubt the high price is to cover the cost of adding that little filter access door and the more secure latching mechanism... both of which are nice features.
