Lens caps while using Lee w/a rings - ideas?

Hi everyone -

I just bought Lee wide angle adapter rings for my 10-22 and 15-85. Of course, I love the set-up but the one annoyance with the w/a rings is that they dont accept lens caps. So, if Im out in the field and want to change lenses, Ive got to un-screw the adapter ring before I can safely stow the lens. During a sunrise shoot and the light is changing fast, I really dont want to be messing with this.

So, what other options are there? Is there a cap size that does fit the adapter ring?

OpTech Hood Hats

Will a slip-on like this work? Notice that they come in finely graduated sizes:

I'd go with the hood hats suggestion.

I tried hood hats and discovered them to be a PITA. They would snag and yank off more often than a push-on, were considerably bulkier in storage (pocket or bag) than a push-on, and took two hands to put on in the larger sizes.

^I'd rather have that than a cap. Caps can vary in size. So that makes it close to none in finding one. Inconvenient? Not really imo.

Lee has introduced the SW150 filter holder for the Nikon 14-24. It comes with a neoprene cover (from Optech) if you wish to not remove the adapter assembly. This is something MNlander is looking for.

Looks like the slip on covers are the way to go - thanks guys!
