How bendable is this lens? I would like to be able to fit/secure this inside of a rigid plastic tube (approximately 6 inches in diameter)

Mine is bendable enough, but it is 7 1/8 X 10 3/8. So I think a 6 inch tube is too small.

it's very flexible i wouldn't recommend you bend it it might break or pop, but it should fit it a tube 6'' in diameter

I agree with other customer. It's flexible enough for a 6" tube, but would certainly break if it's bent too far.

Thank you but I just want to twist off the old plastic lens from the original post then twist on this new one? will that work? Thanks again!

The lens is about 5 inches in diameter. I actually bought this for my mother, who crochets and does needlework. She loves it and has no complaints about it.

You would have to check with your optometrist to see if they can craft the lenses to fit. I have two pair of these, one with plastic and one with perforated steel. It is rather difficult to get the lens out and back in because there is no screw or anything in the frame. The plastic is probably more pliable at elevated temperatures, which could be used to pop the lens out and back in. They were not designed to have the lenses removed.

I made a mistake, the rubber hood is for a wide angle lens up to 50mm or so. Sorry!!

Mine would lock in, but I broke the release lever because I thought it went backwards and not push down to release. I've heard that these aren't exact on measurements, a lot of people having trouble getting their lens to fit. I don't think that helps you at all, but for $14 I wasn't expecting much.

Yes, you can bend it to a fairly tight radius, say 6" radius, maybe even tighter if you are careful.

The ring that is permanently attached to the end of the lens housing has an inside diameter of 28mm and an outer diameter of 32mm. It's only about 0.5mm thick and the same black finish as the housing, so it is unnoticeable. It's been a wonderful addition to my Canon S95. Joel

The bendable portion is 18 inches there is a 6 inch extension you can add at the base but it is rigid. The extension greatly enhances the usefulness of this product.

Using a caliper, I get 67 mm for the diameter of the lens barrel onto which the collar is clamped. The collar opens up completely but I think you could only go up to a lens barrel of about 69 mm, as larger would not fit well. Nor would smaller than about 66 mm lens barrel, as that is where it is fully clamped. Lots of luck! You know, Amazon is great about taking things back if they don't fit.

You may be able to find something to physically attach it, but this, or any such telephoto adapter, will almost certainly cause severe vignetting attached to a lens with 72 mm front. Corners of the picture will be cut and the image will be inside a circle surrounded by black. I had this problem with a 68 mm lens; 72 will be even worse.

The lens increases in length about 4" when fully extended. It is not an internal zoom. There is no lock, and I have not noticed any "lens creep" when using it. The lens hood (which you need for glare and general protection of the lens surface) will add another 3" to the length. It weighs 3.31 lbs so add that to your camera weight. Hand-holding is not a problem, but a tripod is very useful.

I don't see why it would not work. The IS in a long lens is not affected by the extension tubes as far as I can tell. If you're using a macro lens or a reverse-mounted lens, you would not have IS anyway.

Hey Barbara, I would definitely try one a little sturdier. I have this one now on a lighter Nikon (D7000) and primarily use a smaller lens (18-105) and I think it is about at capacity and maybe a little under-qualified. Just one man's opinion but I think something more robust would suit your very nice set up better.

Hello, That would be an impressive move with this lens! Considering it weighs about 40 pounds it would require some serious upper body strength! Thanks for the interest, UsedPhotoPro

I don't know about that specific camera and lens, but it 6 1/2" from the seam that would fit at the bottom back of the camera to the end that the front of your lens would fit into, and would stretch about 1/4-1/2 inch. It isn't quite large enough for my Canon 6D with the 24-135 mm lens. They do make a larger one, but I haven't seen it on Amazon. When the one I bought on Amazon didn't fit, the company sent me the larger one.

You can make the cup just a bit bigger just like you can make a lens longer. Don't buy this cup it is a piece of junk!
