what is the lens housing made of - metal or plastic?

Majorly of plastic. The uv lens has a tendency to reflect back light. I don't use it. But it's still a great product and a must have in your lens kit!

The lens housing is made of plastic. This lens is sometimes referred to as the " plastic fantastic".

The lens is actually a polycarbonate which is a optical quality material and virtually unbreakable. It is actually a lighter and more expensive material than glass.

They're plastic lenses. My husband absolutely loves them. They're perfect for fishing with the polarized lenses.

It is a metal or hard teflon type material. Fits well, though I bought a HOYA 58mm uv lens and the fit is not good at all.When you eventually get it on you dont want to keep taking it off. I would go to a regular camera store with my camera next time, maybe a bit more expensive but you can see what you are getting.

Apologies for not answering earlier.. Although I have not used it in a while, as it is a spare, the overall piece is light( due to the plastic frame construction) and I am near positive the Lens is glass.. Either way, it works when needed and was not pricy at all. Still would recommend it..

They give you a selfadhesive metal ring ,the lens is magnetined. the lenses are not that good.

It looks like aluminum, or could be a very light weight stainless steel. The surface does not attract a magnet. It is not a shiny metal, except for the ring around the lens area. I don't know if this answers your question, but hope it will be helpful. Bar Con

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

Red lens. Black plastic housing with a dog ear at each end for mounting and a shallow recess along the rear for keeping the wires out of view.

The lens is definitely glass. I recalled the casing being metallic of some sort but I just inspected it and it appears the top is a hard plastic around the glass lens. I'm still pretty sure the base has metal, but I can't tell without digging it out.

Plastic. It has to be plastic to flex open enough for the camera to pop into the housing. I don't have any concerns about the durability of the plastic.

The lenses appear to be glass, the case is plastic.I will add that this has been a very worthwhile addition for night spotting out to 100 yards.

These are a polycarbonate plastic lens sorry glass is almost non-existent now days with headlight assemblies.

Plastic. But replacing them was not much more than getting a professional to clean the fog from the lenses.

It is plastic, but according to Ken Rockwell (kenrockwell dot com ) and his very glowing review of this lens, it is "good" plastic. (That's why it is so reasonable in price) But according to Ken's review, the optics are superior to any other Crop Sensor UWA out there - including the much more expensive 10-22mm from Canon.UPDATE 29 Aug 14: Now that I have had this lens for a couple months, I will say that, while it is plastic, it doesn't feel "cheap." The mount is machine-grade plastic and fits very nicely on my 7D. For the price, this is a heck of a lens.

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

The lenses are glass, and the housing is aluminum. I don't remember much plastic on these.
