Optolong L-Enhance EOS Clip Filter Fitting issue

[martinclayden]

Not sure if this is the right group for this ?

I just received one of these filters (Jan 21) from FLO and I am having great difficulty in fitting to either a Canon 60Da or 77D

When inserted, the filter sits on these ledges (I think - they are under the filter) - and CANNOT be clicked into place. I've also tried an angled insertion technique I read about, to no avail.

With a lens fitted the filter moves around (not a massive issue for me as I use the camera for astrophotography - and the camera is always pointed up), but still, at the price, I'd expect a secure fit

Has anybody got any advice

Thanks

I cannot see too well as the picture is quite small but from memory  (I do not have a DSLR anymore) it does not actually clip in but lays inside like you have it then when you attach a lens, or attach it to an adapter to fit to your scope that holds it in place more securely.

I have an Optolong UHC clip in filter and you are correct that it sits on those ledges. My filter fits in firmly and doesn't move at all - it requires some effort to remove it. It doesn't so much 'clip' as is just a tight fit . This is in a Canon 7d mk2 so the exact same ef-s mounting as your camera.

Interesting, my filter sits loosely on those ledges, it's not firm at all. Videos on the web suggest a push click fit.

With a lens fitted the filter is free to float forward, but probably only by 1 or 2 mm

Videos on the web suggest a push click fit, with an ef-s lens the filter is free to move a couple of mm

Optolong's web site push firmly. I think their manufacture tolerances or dimensions have changed

It should have two little 'arms' on the bottom of the filter which can be carefully bent either in or out to ensure a secure fit.

Not on my filter - it has a little notch cut out so the filter itself has a little flex in it. I think the filter is made slightly too large which is why it then provides a snug fit in the camera. The picture below probably explains it better...

Here's an image of my filter, two notches, two springs and NO flex and a loose fit!!

It has the two arms, which I thought were springs, I'm reluctant to attempt to bend these

You will be fine giving the arms a little tweak, place a small flat head screw driver in the gap and just twist alittle. It only takes a small adjustment. I did it on mine and it worked a treat.

I did just as you suggest - nervously - but it worked.

Many thanks for the tip!

incidentally - while reading about this issue I came across the controversy from 2016 about these filters being a copy of Astronomik's mechanical design, but it's suggested made to lower quality standards - explains the poor fit

I think the Canon cameras do vary from model to model slightly.
