Variable ND Filter for RF70-200 F4 L IS USM that will still allow use of Cannon Hood.

I am hoping someone out there in Canon-land can help.  It seems like every variable ND filter I have found on the market has a slight increase in diameter from the threads which on several lenses prevents the Canon hood from being removed or attached.  I have experienced this on 2 canon lenses.  My main goal is to avoid having to carry the hood separately if I want to use the ND Filter.  Unfortunately I have been unable to find any forums that answer this question as commenters seem to think any 77mm Variable ND will work and the question goes unanswered.  

One option I considered was a step down to 72mm.  However I'm not sure if I would get any vignetting and if so how bad with this focal length lens.  I'm new to doing Video but I want to be able to shoot video of wildlife from a distance.

Thanks in advance to anyone who can help!

Time for a matte box or a video lens hood.

Yeah, because of the adjustment of a Variable ND Filter, I bet you are out of luck. I've seen some with pretty large knobs so no hood is going to fit. I have almost 100% stopped using filters but I don't shoot video so it makes Photoshop an easy way to accomplish the same effect. I bet there are video editors like PS that might work for you.

Bad thing I own a ton of filters! 😐

Hoods interfering with filters is common. Being able to reach a filter rim to turn it (variable ND, polarizers, etc.) is tough or impossible with bayonet-mount hoods.

Check out Maven Filters. They magnetically attach to your lens via a screw on adapter ring or their clear glass Splash Adapter rings (which is what I use). Their filters are Tier One filters. They also make metal lens hoods which attach magnetically as well and will rotate with the Variable ND’s or CPL/LPL filters. 

 As a side note, I’ve fallen in love with their magnetic lens caps. No fumbling around trying to attach it when the lens hood is on or having to remove filters to use the OEM lens caps. All my Canon lens caps are now gathering dust in a drawer, lol. 

My RF24-105mm L with a splash guard, LPL and lens cap; lens hood attached in reverse (and in case you’re wondering why my lens looks different, I’ve covered it with an AphaGvrd lens skin).
