Another arrival joining my M42 collection. This time it’s a “Sun Zoom YS-85 F:4.5 85~210mm” lens. It’s definitely one of the most interesting and attractive lenses I have ever seen. I love the very original design, zoom and focus control is also very smooth. The wide silver ring at the end extends and acts as a built-in hood. I couldn’t google too much information about this less, any info would be appreciated.

Heb nog meer info staan maar denk dat je hier wel even mee voor uit kan.
Sun Auto Zoom 85-210mm F4.5 Constant Aperture Zoom Lens. Works great on classic film camerassuch as the pentax Spotmatic series or Mamiya 1000, Praktica and many others. Nice zoom lens that can be adapted to many digital cameras, adapter not included, but readily available here on eBay. Nice condition, ready to use. Has beautiful coatings. Rubber on zoom ring looks it might need a little glue to look perfectly but works fine as is.
Great lens for use on DSLR's (all makes) and mirrorless digital cameras such as Pentax K1, Sony NEX, Canon, Nikon, Olympus, Panasonic, 4/3 when used with proper adapter (not included), but readily available here on eBay. If you are looking for an adapter on eBay, search on this term "Lens Adapter Canon M42". Just substitute "Canon" with your make of camera. Many adapters will come up, I would suggest picking one of good quality as you will be able to use any Pentax M42 Screw Mount lens with the adapter, and these lenses are far better than the lenses made today.
