Sorry, I am not exactly sure what the lens material is, but they are very crisp, clear and thin. They are not glass but I can't say for sure if they are poly?

As far as I can tell they are plastic. and not made the toughest but I have to say I love them as they are perfectly focused at the correct distance FOR A COMPUTER.

They're made from a hard plastic that can support my Canon 70-200mm f2.8, bust some parts are metal, like the release latches and the autofocus connections.

I used some of the packing material from the package itself...some foam padding to prop up the camera so the lens is centered in the bag. I think I also wrapped some thin foam AROUND the lens and used a rubber band to hold it in place (I havent used it in a year or so at this point)

It is made of a high qyaility plastic. The material is similar to the body of the Nikon camera. The connection to the camera is secure. There is a roller that will seat a screw into the tripod connection. I am very pleased with this device.

The frame feels and looks like powder-coated aluminum. As to whether the lens is glass or plastic, I can't tell.

This lens is not weather sealed. It does use a Thermally Stable Composite material for durability and temperature stability. And it feels great.

They are anodized aluminum construction, its sturdy I have even used it with the heavy Pentacon 200mm Lens which is solid-and mostly all M42 Mount lens are usually heavy, I have a couple like also the Russian beautiful Jupiter-Lens 85mm-are old but all made East Germany-even the earlier Carl Zeiss used on the Exacta Camera's.

The lens is molded optical plastic. This makes the magnifier lighter. The only down side is that the lens will scratch easier. But you should be careful with any optical device!

The lens is glass, be careful to install it. Even though there is metal frame to protect the lens, don't drop it.

The actual magnifying lens is made of a thick quality glass. The lens covering the light tube is plastic.

they are plastic. What I figured out how to use them I have had a blast with these things. I use them with my stock lens. I went online and found out how to use them properly and I have gotten some very good macro shots although I do have to focus everything in manual I'm enjoying playing with them and experimenting with my photography.

I don't know what the material is, but it's very durable and padded. I got it before I went on a church bus trip so that I could just leave my 135 mm lens attached. I highly recommend it.

Lens is clear plastic. Body and rubber outer gasket are black/grey-black. Once installed, they look like original equipment. I am very satisfied with the ease of installation and appearance.

Part plastic but the screw-on part has metal flanges so I'm comfortable with the construction. It is an amazing lens, with great sharpness at 200mm or more. It is also great for floral closeups. Definitely better than the old DA 50-200. I wouldn't part with it and I recommend it highly. One of Pentax better lenses. Freddy B
