The auction you are looking at is a job lot of 3 senses. I know nothing about camera equipment so this is basically say what you see.

The first lens is the largest, it is marked 75-300mm but the rear cap seems to be stuck on. I cannot get this off and do not want to force it so this is exactly as it will be sent.

The second lens is marked 28-70mm and all seems to move freely.

The last lens is the smallest and marked Canon 50mm.

I am sorry I cannot tell you more but I really do not know anything else about these.
