Rediscovered this morning in the deep dark depths of the collection, this is a lens that was released under several different brands including Vivitar. This is the Pentax KA fit and has caps and original box but I don't have a lens hood for it.

Condition is overall very good - aperture is clean and snappy, focus action is smooth and optics are in good condition - there is one very fine scratch on the rear element (difficult to spot under most lighting). It's very compact and lightweight, so a great addition to the pocket/bag as an ultrawide for full frame or medium wide for APS-C.

This lens doesn't get great reviews and it certainly isn't in the same league as the Pentax 20mm offerings - it is reasonably sharp when stopped down a bit, contrast is fairly flat, and it's not the great at handling flare - but with a bit of processing it can achieve some reasonable images. Corners are pretty poor generally, so subject matter should be considered to make the most of this.

Here are a few shots from a little walk this afternoon...
