Does the lens with this amazon kit have a steel mount or is it plastic?

The bayonet mount itself is a nonferrous metal, aluminum I suspect. There is a plastic ring around the inside of the mount, but I don't think it has anything to do with the mount itself.

Lense is plastic. But thick and pretty scratch proof. I don't think it's convex, pretty flat on the face. I'm very happy with it though. Went in a '81 Kawasaki KZ750 and with a Silverstar bulb is a 1000% upgrade over stock sealed beam. I like it...

Both screws on this mono-pod are plated steel. The main tubes look to be aluminum. It works very well with my movie and SLR with a long lenses. I am typically working from the bleachers and I use the mono-pod at reduced height. It really increases the stability. I recommend it.

It is polymer. I would add that it appears quite sturdy and durable, though admittedly I have not properly tested it. The fit on my Core15-M4 is perfect. One drawback in my opinion is that it is quite difficult to switch between the large and small apertures. Selecting apertures requires too much work and fine manipulation and therefore cannot be done "on the fly." All in all, I'd say it's worth the price but would like to see an improvement to the aperture selection feature.

The only plastic is the lens cover and the part that is around the lens. There is a plastic knob right above the lens. I find it very sturdy other than the lens cover which I took of in the first 5 minutes that I used it because it had nothing to hold it open and just flapped around. No biggy to me.

It is metal. The whole thing is solid design with smooth bearing motion. I have used it with three different size cameras and it is easy to adjust for each.

Hard Plastic. Probably what is often referred to as "nylon", although I'm no chemical engineer. These Pedco mounts hold pretty well, however. You could always put on a rubber washer, or just a piece of rubber gasket material with a hole punched in it it, however, for a bit more grip. I was surprised that some reviewers felt that they were not substantial enough to hold a DSLR with a heavy lens, as I've used them for that several times now without a problem. But when vibration or a catastrophic fall might be an issue, I've always used some kind of "safety strap" - or (once) just a length of cord - attached to the strap mount(s). At least, I've done that since one of my lens caps fell into a clutch of baby alligators. True story. I did not think that the lens cap was worth retrieving, as I did not know how far away - or not - "Mama Gator" might be at the time. Not for a lousy lens cap. anyway... Better safe than sorry, right?

It is plastic. For the price I am happy. Even with a long lens the locks hold. It would not be suitable for a professional.

I assume it aluminum, it heavy but not Steel heavy, but I'm not sure sorry, its a great mount though, I love it.

They are plastic lenses. If you order 2 identical sets in the different strengths you can unscrew and trplace the lense

The pole itself is made out of metal, the handle is rubber, and the mount is plastic. Good product!

Plastic. What I did before installation was I put 3M protective film on the lens. No cracks or nicks.

It has a glass lens and it seems to be very water tight. I was surprised at how well it was built and it is bright. The only thing that I did not like was the pot metal brackets. I welded solid brackets to the bumper on my jeep before I sent it off to be powered coated.

No. It is a preformed piece of plastic like the mounts that come with the camera.

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

No,the lens is solid from the time I got it. I had for a few years now and love it.

I got the "silver" one because it's steel. The other may be aluminum. I don't know. My adapter was well made and fit my Canon 5D MkII and the lens, a Helios 58mm f2.0.
