Canon 15mm fisheye - any ideas for lens cap modifications?

If any of you have used/owned one of these, you'll know how poor the lens cap fits over the lens itself.

Has anyone done any modifications to the lens cap so that it sits on tighter without falling off?

I'm about to buy it in the next few weeks/month- I posed the question on here and Fred Miranda, and someone mentioned because the lens cap was metal, they squeezed (bent) it slightly , and it fit snugly. Others mentioned a rubber band, gaffer's tape, etc.

I took one of the tiny felt pads that are used to prevent kitchen cabinet drawers from banging into the cabinet face frame. It self adheres, works great, and keeps the cap on tight. They're cheap, and it beats denting the metal hood...

Did you de-felt the hood first?

I've used one before and the cap is terrible. It won't even stay on usually inside the bag.

when i used my cousin's one, i kept rubber bands on it while in my bag.

I fixed the problem that the 14-24mm F2.8 nikkor which has the same slip on style cap. I use some Velcro to make a strap that locked the hood on to his lens that was easy to remove.

Any other suggestions out there? I've just acquired one of these for LensesForHire.co.uk and I'm after a professional-looking solution which will be relatively foolproof. (I can't rely on customers to attach rubber bands etc.)

I stick mines in a tight closing lensbag thingie.

I just looked at mine to see what I did since its hood fits well. Well I did nothing. Guess I am lucky.

If I had to do something I would use hockey tape and lay it on the inside and wrap it over the cap lip so it covers the outside as well. That would keep it from rolling off when you put it back on the lens.

For a more professional look you might try re flocking it with something like this.

You can call and ask them if the glues would stick well to metal. They tend to have someone on staff that knows each of their products.

I heard if you bend the metal, that it would give enough clamping force.

Wish they wouldn't make it out of metal scratches and dents too easily .

No reason to...the pads are thin enough to just give the right amount of friction. I adhered a single pad to the inside rim of the lens cap. Works like a charm, and I don't know how one can get more "professional looking" than that since its never visible (unless you spend all your time staring at the inside of the cap.

Just a reminder...these are the tiny felt pads that attach to the rear face of a kitchen cabinet door, not the thick, bulky pads for chair legs.

*stops staring at inside of lens cap*
*puts down lens cap*

You got me there...

I used to do the rubber band trick, but it was a real PITA. I had some of these pads laying around my woodshop and gave one a try. The rest, as they say, is history.

The rubber band trick works, as long as you take the lens of the camera. Wih the lens remaining on he camera, it doesn't, unless I use a very long elastic band that goes around the camera as well.

Will have a look at my box of screws and tricks in the loft. Think I've got some of those kitchen door stickies in there. Will give that a try.
