Actually, Dan, the K-mount Zenitar 85 is actually an f/1.4 (with, as I recall, a whopping 72mm filter thread - even wider glass than the A* and FA* 85/1.4's), and I don't really know if the Helios 85/1.5 is optically similar to the Zenitar K (which is certainly quite different in design from both of the Pentax 85/1.4's).
