The problem with all the cameras in the photos is that they are not in very good shape.
- The Yashica has the foggy viewfinder.
- The Minolta looks to be missing a few things (ours came with two close up filters, two coloured filters for B&W and two screw-in focus distance chains) along with a nice owners manual, and the box looks very beaten up.
- The Canon has a TC mounted in front of a 50mm lens, something that is usually not recommended.
- The Diana is nice that it has the flash and the box, but the box is pretty beat up.
- The Kodak 8mm movie camera, I did a lot of stop-motion films but never used a Kodak.
Each camera would probably go to a collector interested in that particular type.
I think though that you will find the sold prices on eBay to be low.
