Does the lens frame made of plastic or metal?

It's metal, but I am not expert about the quality, you just need to use it for quite awhile to be sure. I got it last 2 weeks, and I am pretty happy with it, no problem. I can also stack them together easily. All double thread.

They are made of metal. The tulip (flower) lens cover is a heavy duty plastic. All very durable.

John, I just checked the camera and I do believe the lens is glass and is protected with plastic. It is a Leica lens.

it is plastic, but the base frame and the lift mechanism is metal. The inside trim is also plastic.

The frame is plastic and mounts with metal hardware. I tried to scratch the mirror with a dental pick and couldn't penetrate the surface, so it is very tough. I'm pretty sure the mirror is made of plastic.

The frame is metal and the four corner braces are plastic but made of good quality! We have had our game for a couple of years now and it still works like new!

I do believe the case is plastic. It does not feel like metal. I make sure I keep it in the case and around my wrist when using the camera.

All metal. Very durable. I use mine on every shoot either with my led light or external monitor.

The piece holding the lenses are hard plastic and the other part is a rubber material.

Sorry, all the inexpensive lenses are plastic. Just be careful you do not place them lens down on a surface.

It's plastic. But, I'm pleased with it. I've never used a Nikon grip, so I cannot compare. But, user reviews were mostly positive about it, so I saved myself a BUNDLE OF BUCKS. You might not want to use it on a tripod with heavy lenses, possibly too much stress on the plastic construction. FYI, on my Nikon D800 if there's no battery in the grip, the camera won't shoot.

The material around the lenses which fits around your eyes, is heavy duty, durable molded plastic. All lenses appear to be glass. All metal looking parts are metal (magnifying eye-glass frames, metal fasteners around the main eye lenses,etc. The only exception to this is the decorative gold/silver gears on the sides--they are attached to the main molded plastic frames and they are plastic as well. The strap to hold them on your head is adjustable 1/2 inch elastic--but can be easily replaced with more durable material if you plan to wear these with regularity. These are very sturdily made.

It is not metal, I believe it is glass. The clarity of the mirror is outstanding, so I don't think it is plastic. As others have noted it is larger than many helmet mirrors, yet it is not heavy and is very stable. Best helmet mirror I've owned.

Plastic. The entire housing is made of the same stuff, aside from the inside reflector and the mount.

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.

I believe it is plastic with metal frame. In fairness I will say that it's pretty hard to tell - visually at least. They look nice, especially with light on.

The lenses are plastic. They make a huge difference when the original lenses are almost 20 years old.

The Black and clear part of the loupe are plastic. The lenses are glass. It works really well.
