Does this holder tighten down on the lens barrel with a screw? If not what holds it secure?

There is a ring mount (sizes vary per lens) that screws onto your lens. The filter holder then snaps onto the ring. They are fairly cheap but sold separately.

There is a threaded adapter that screws into the filter threads on the lens. The the filter holder clips onto it

The Cokin filter holder does *not* tighten down on the lens barrel with a screw. Instead, an adapter of the appropriate size screws into the lens barrel (like a regular filter) and the universal Cokin holder slips securely onto the adapter. You will need to buy an adapter for each size of lens that you plan to use with the filter holder. You can find adapters on Amazon.

You press on it and then secure it with a screwing motion. It stays on all right, although it seems hard to believe that rotating it won't unscrew it. (Once I had it on the lens, I never had a case when rotating it - to get the filter in the right position for a shot - unscrewed it inadvertently.)

There is a knob to tighten it. However, I personally cannot recommend this device. I bought it to hold a 7 inch monitor and had a hard time getting it adjusted to the angles I needed without it falling. Perhaps they aren't all this way but, mine did not work like I thought it should.

There is a rubber pad that does a pretty good job holding the camera in position. However, if you have a heavier lens or other gear mounted to the camera, an additional method of securing would certainly help.

The light fits into a holder. . And the holder tightens down onto the light. .. it is very secure! ! I WOULD buy another one! !

There is a little threading but when i asked customer support the same question via email they said there wasn't. I don't know what diameter the lens is and i doubt there is a 3rd party filter. However i did do an amazon search and found one that looks like it is mounted to the lens with three screws. But with it being a zoom lens I don't think it would stay on when fully retracted.

It has a strap that's threaded and a nut that tightens it down. The mount is plenty secure. The case slides into the mount and clicks in. Then you push a plastic lever down to entrap it so the case can't just fall off the mount

Yes, it does attach to the 1/4-20 screw. I would go for a 90mm to 100mm release plate for that size lens .... maybe even a 115mm.

yes there is a lens lock on it but I have not had issues with it sliding without using the lock while taking pictures in a downward angle.

No, it's not made for that. Mine is very secure. I only bought a replacement as someone borrowed my camera, took the lens cap off and put it in their jacket then left their jacket.

Yes, mine came from the manufacturer with a removable (of course, lol) lens hood. It is the plastic type that attaches to the front of the lens and secures with a quarter-turn.

It screws onto a lens but if your lens isn't sturdy enough it won't work properly and sometimes won't even attach. It's a terrible product.

If you're referring to the knot that locks the camera in the mount, you don't have much movement so you need to adjust it first, then if done right you'll have a little movement to lock it tight.

My 12mm lens shows the holder on the edges. I don't know at what point it disappears.

It seems to hold my spotting scope ok (that's what I bought it for). The tightening lever for the base plate broke the first time I used it though, even though I put very little tension on it. Luckily, I had an old tripod I could use for parts.

There is a small lever that releases the pin that holds the adapter to the lens. Its not the strongest so handle with care.

I put the lens side rearward; since it is leather, it should loosen up; I believe I remember it was tight at first, then perfect after a short while. Also, I use the strap as added protection to keep it from sliding out, and perhaps you can use the same strap, to pull it out until it loosens up.

It screws into the base of the camera however it adds a 1/2" to the camera kind of making it less stable if you have a heavier lens on the body but I love it, it works great
