I'm selling the UNOSCRA I received in April, which was available for pre-order in January. Unfortunately, I haven't had a chance to use it, so I'm reluctantly putting it up for sale. I only opened the box and held it once; it's unused. It's designed to be used with an M42 lens to enjoy the images it projects. There are plans for a re-release, it seems. This is a challenging product, and it's from the initial production run, so please understand that. I'd appreciate it if you could purchase it with that in mind. I want to sell it to someone who will actually use it. *I don't have a lens myself, so I haven't been able to try it out, and I can't really comment on the user experience.* The price is just the purchase price plus the Mercari commission, so I'm afraid I can't offer a discount.
