Filter (adapter) Question

I like using filters on my lens, but I absolutely HATE having to screw them on and off. Do they make an adapter that would allow the threaded filters to simply slip on and off my lens for quick change?


Before you suggest Cokin or Lee, I dont want to switch to gel or rectangular glass...I have 8 different 67mm threaded glass filters (from Hoya and B&W), I like them and I want to keep them...so I want something (either to purchase or make from spare parts) that will attach to these filters and allow me to simply push them onto the front of my lens (so I will need something with a 70mm inner diameter on the lens side). I also want this "adapter" to attach TO THE FILTERS and NOT to my lens...I dont want to have to remove the adapter to put the stock lens cap back on.

I've searched Google, I've searched online photo shops, and I've searched the threads on many photography forums...all to no avail. What I'm looking for may not exist, but I'm willing to make it from scratch if I have to! I dont care if its rubber, metal or plastic, I dont care if its ugly, and I dont care if I need one or EIGHT (as long as the fit is snug and secure and it DOESN'T involve duct tape)...I just want to use my EXISTING filters without having to screw them on and off.

A friend of mine has a WB filter called an "Expodisc" that he's able to push onto the front of his lens...so I figured there MUST be a way for me to do it with MY filters.
If anyone here can help me, or has any ideas about who can, please let me know? I need something for 67mm threaded filters. You can email me directly at saycheze(at)gmail(dot)​com

Thanks, Dave

meh, i dont think any such thing exists. and if it did i wouldnt want to put my filters on one. No offence, i just think they would fall off to easily. we paid a lot for those B+W filters, the last thing id want to hear is one falling off onto the cement. Sounds like its definitly something you would have to home make. but i dont see the big deal with taking the filter off by hand in that case.

Are all your lenses 67 mm? If so, then you'd need to replace all your filters anyhow, since the mounting for the filters would need to slide over the outside of the lens. And that would interfere with using a lens hood. Then there'd be the risk of the adapter slipping off, and the problem of making sure it's square to the lens, since a tilted filter could really mess up your photos both through refracting incoming light and through catching off-axis light and encouraging flare.

I have other sized filters for the other lenses that I use...but the 8 filters that I mentioned are all 67mm. I purchased them at a garage sale from a lady who had NO idea what they were...all 8 were in the original cases in a shoebox, and I got the entire box for $10.00...no BS, ten-bucks!!

Given the fact that I basically stole these, lets say that I didn't care about the them falling off, or being square to the lens, or leaving room for a hood...in fact, lets say (just for arguement's sake) that all I care about is a way slip a 67mm filter over the front of my 17-85 EF-S.

Can it be done, and if so, what would I need to make it work??

They make the "Expodisc" to slip over the front of a lens...but I've never see one up close to know how its done. Does anyone here have one, and if so, how did they accomplish it?

I believe Expodisc uses a mechanism not that dissimilar from a lens cap. However, with an Expodisc, you don't need to be plano-parallel or as close as possible to the front element to avoid introducing unwanted artefacts to the picture - the Expodisc, is just an aid to metering and white balance.

Though you've already dismissed it, I think this is a job for a rectangular filter holder - though that has its own issues with adjusting and securing the filters.


What may be more productive is practising centreing a filter in the threads on your lens(es), which will make for quicker changes with your screw-in filters.

whats the big rush to change filters any way, i mean do you really cycle through that many filters during one shoot and is the really a pressing need to change them quick. or are you just after a flash looking gadget. i know i haven't really offered you any advice, just interested in your motivation

No, I'm not changing filters rapidly...in fact, its quite the opposite. I have nerve damage and muscle weakness in my upper extremities from a motorcycle crash at Sears Point Raceway in 2001 (which is why 99% of my shots are done using a tripod). I have a lot of trouble lining up the threads and I'm tired of struggling (imagine trying to screw a filter on your lens after both your arms have been submersed elbows-deep in ice water for an hour or so, while at the same time someone periodically shakes your upper body...and you can begin to imagine the comedy that ensues when I attempt to change my filters. And if you think THAT'S funny, you should see how long it takes me to type this.


My other option is to avoid using filters altogether, but I'm trying to see if I can produce results in the field like I can with post-processing (which is tedious and mind-numbing for me)...although I did invest in Adobe CS2, my lack of interest in overcoming the learning curve of the software keeps me from utilizing it to its full potential. Plus, I just like filters...I also want to get one of those Lensbabies.

Anyway, it appears I'm going to have to get a machine shop to manufacture what I need.

I think getting something manufactures would be the best option. Maybe a kind of adapter to get the filter to attach to the lenses bayonet / attachment for the hood? (If all your lenses have the same type of hood)

Nice sense of humour by the way...
