I got these old lenses from a family friend of my wife's mom thinking I may be able to use them. I guess she used to be a photographer but I don't know if she was a professional or just a hobbyist. Anyways I am wondering if these are good lenses, if they have any value, or at least any trade in value. These are fully manual lenses (focus and aperture) and also I am not sure of the mounting type. They look like my cannon mounting but too small. My wife's mom seems to think she used Nikon. Here is as much info as I have. These are all metal and heavy for their size so I assume they're decent for what they are and from the time period.
