Monopod with anti rotation mount

Yes. Of course a monopod rotates easily. What I want is to be sure my lens doesn't unscrew from the monopod. I'm planning to get an

Arca compatible quick release plate (such as a Kirk LP-1) for my 300mm f2.8L lens and an Arca mount which has provisions for anti-

rotation screws, but I'm not seeing any monopods from Manfrotto or others that have anything other than the center screw. This as

opposed to tripods which have provisions for additional screws to prevent rotation of heads.

 

I see lots of photographers who have the lens on a stick they carry over their shoulders. Surely there is some provision to avoid the lens

loosening on the screw, but I don't see it.

<p>You could use a small amount of blue Locktite (forgot the #) or the RRS version (threadlocker fluid) to keep the clamp firmly mounted to the monopod's screw stud. Having said that however, I've never had any "rotating" problem you described after decades of shooting sports with my monopod & clamp combo. Just simply keep the clamp and monopod torqued tight and you're good to go. No problem with carrying a large lens-ka-bab the way you described either without any anti-lock device. </p>

My guess would be to use lock title as well. But I've never known this kind of slippage to be an issue.

<p>Ditto Wilson's and Ellis' remarks. I've carried a 400/2.8 on the end of my Manfrotto Monopod and the lens/mount doesn't wobble or rotate - I simply screw it on “really tight”.</p>

<p>You could drill an hole.</p>

<p>But to answer part of your question, but maybe of little practical use to you, I have seen a monopod with locking screws on the top platter. It is made by (what I thought was) "Vortex Instruments" - I just did a quick search and it is discontinued. It was an “all in one rig”. Here is a link for your info –<br>

Thanks William. That Vortex with the

set screws was just the setup I was

looking for. It even has a gun rest

attachment. I was starting to suspect

that feature might not be needed, but I

have experienced my 300mm lens

falling out of my 5D mkII mount. Turns

out it's a common occurance - I

googled it. I would hate for it to fall off

my monopod after up and down

shouldering at an all day track meet. If

your 400mm is staying on, my 300mm

should be fine. I may still take a look at

the Arca adapter and put my drill press

to use.

<p>That’s interesting that you have found some Photographers have this problem.</p>

<p>For clarity, let me explain precisely that I attach the <strong>Lens's Ring Mount,</strong> <strong>directly to the monopod</strong> and I have never had this problem of the lens working loose. In my experience most Sports’ Photographers mount large Primes to a monopod directly via the Lens Mounting Ring. I’d be interested if any that have reported working loose when carrying, have the lens mounted directly via the Lens Mounting Ring.</p>

<p>For clarity, here is a snap of what I describe: <br>

William, sorry for confusing the thread.

I have never heard of a lens falling off a

monopod.

 

What I made reference to in my later

post is the lens falling off the camera -

no monopod involved. Turns out large

lenses come loose in Canon 5D mkII

cameras. Common symptom is

autofocus not working, until you twist

the lens back into place. Worst

symptom is the lens falls out while you

are walking.

 

It was that experience, and seeing set

screws used on tripod heads, that had

me wondering if monopods with just

the single center screw would allow the

lens to accidentally loosen.

 

Of course, when using a monopod, or

tripod, I mount to the lens ring. Sorry

for confusing the issue on that. Unlike

the 400mm f2.8, I find the 300mm f2.8L

hand hold able for most events, like

track and field when only covering a

few teams for the newspaper. When

I'm the event shooter for a marathon,

not so hand holdable.

 

I am convinced from your experience

and the lack of set screws on top brand

monopods, that loosening must not be

an issue.

<p>Ah! OK! Thanks for clarifying. Ive just re-read what you wrote and it was <em><strong>my misreading</strong></em> of your sentence. My error.</p>

<p>Based on Ray's latest description, it sounds like a possibility of worn out lens mount (due to wear & tear), either on the lens, on the camera, or both.</p>
