Adjusting CPF with lens hood on

I was taking some photos while sailing yesterday so I wanted to use a CPF with the hood on my 100-400.

How do you adjust the filter with the hood on? Anybody have an idea?

Some folks have modified their rigid hood by cutting an elongated hole with a dremel in the bottom of the hood to allow finger access.

I pop the hood off, adjust the filter and put the hood back on...

Ouch! That's a little too drastic for me.

I was thinking of doing that but feared losing the lens overboard if we hit a wave. I finally just adjusted it as best I could in portrait postition, stuck the hood back on and kept it that way. It would have been nice to have the ability to adjust it.

I would hope that the lens was attached to the camera which was on a strap around your neck. As far as losing the hood overboard, I find I can slip mine onto my wrist like a bracelet while I'm adjusting the filter and then slip it back onto the lens.

Pentax makes their hoods with a little "tab" that pops out so you can easily adjust the CP. AND they include a hood with pretty much all of their lenses (including the humble 18-55mm kit lens)

So take a hint from Pentax Canon!

(and Pentax, take a hint from Canon and improve your autofocus )

Oops... meant HOOD, not lens. Yes, I was wearing a neck strap. I'll have to see if the hood will fit over my fat hands, that's an excellent idea! Thanks for the suggestion.

Actually, I've seen some of the finished products...they look really good and are functional. There's either a thread on here or on the Fred Miranda site with detailed pics. I'm sure that you can find it on google if you're curious.

One reason I went for primes...

The 300mm f/4L IS and 400mm f/5.6L have built-in retractable lens hoods. Makes adjusting the CPL a breeze. Heck, even the inexpensive Tamron 400mm f/5.6 ATX which I used prior to my 400mm L glass had a retracting lens hood.

I wish Canon had put these on all their tele zoom lenses including the 70-200mm (series) and the 100-400mm L lens.
