This is a vintage Cosina Zoom Lens for Pentax PK Mount.
It is specifically a Cosina 28-70mm f/4 MC Macro which is in excellent all round condition. The optics are great with no sign of scratches or fungus and just a few small dust particles (do not affect images). The exterior is in great condition and the zoom and focus action is smooth and fluid. A little of the yellow paint on the focus barrel has worn away but that are its only let down. It is a very solid lens weighing 420g.
It comes with generic front and rear lens caps. The front lens cap is the pinch type and the rear lens cap has the letters PK on. The lens has the serial number PK93303749.
I have used this lens on my Micro 4/3 camera and by using the correct adapters, you can use this lens on a multitude of modern cameras - often offering excellent images at the fraction of the price of many modern lenses.
It is a decent zoom lens with the advantage of having a constant aperture. The macro function is useful for taking photos of butterflies, flowers and such like and in macro mode it has a minimum focus distance of about 16 centimetres (6").
This Cosina 28-70mm f/4 MC Macro zoom lens will be sent well packed and promptly. My postage charges are very fair and I do not make money on shipping. On valuable items such as this I only offer certified/tracked (Certificado) postage to ensure that you receive the item purchased.
I am new to Etsy after having been a seller on eBay (and before that Yahoo Auctions) for many years with a 100% rating of well over 2000 sales. I specialise in cameras, camera lenses and filters and other camera gear, but I will also add other vintage items over time too. Thank you for looking :-)
