I recently acquired an SMC Pentax-FA 645 150mm F2.8 [IF] and have taken a few pics to test it out with the the 645Z. All of them are handhed. So far I am loving this lens.
The first is a picture of Duntrune Castle across Loch Crinan in light rain in the foreground and background with a shaft of sunlight lighting the middle to background. This has resulted in the inevitable 'grain' the rain produces but also quite painterly light.
This is a shot of swallows amassing in preparation of their long flight south for the winter. Not too happy with how I have compressed it for web but I like the isolation of the cable/birds.
And finally a shot of my new working cocker spaniel puppy Ellroy at 14 weeks old.
