Hi guys, newbie here.

I recently got hold of few cameras and lenses, unfortunately I can no take their photos rn, but I'll do my best to list the condition.
I would be very grateful if someone would give me realistic price estimate/suggestion where to sell them.

Here it goes:
Olympus g.zuiko auto 50mm 1.4 Brand new in box, never used
Robot II Star with Xenon 1.9 40mm with minimal signs of use 9/10
CZ sonnar 1:4/135mm (This one has ZIAG on the box) minimal signs of use 9/10 but box seems used
Polarpid CU-5 minimal signs of use 9/10 no box
Pentax K1000 body only same condition 9/10

+ Olympus focusing lens 1-9 brand new in box
Olympus SM-2S adapter brand new in box


I'd be really grateful for the info.

Thanks

Olympus g.zuiko auto 50mm 1.4 Brand new in box, never used -> $100 to $150
Robot II Star with Xenon 1.9 40mm with minimal signs of use 9/10 -> $300+?
CZ sonnar 1:4/135mm (This one has ZIAG on the box) minimal signs of use 9/10 but box seems used -> $80-$120
Polarpid CU-5 minimal signs of use 9/10 no box dont know this one
Pentax K1000 body only same condition 9/10 -> $70-$100

The Polaroid CU-5 is a specialist, professional camera for close-up and macro photography (e.g. used by dentists) my best guess is 150-200 US$
