If you found your way here, you already know what you're looking for. This is one of the most beautiful pieces of Pentax glass I've operated. But, this is a serious lens and requires some technique to get the best from it.
I do not have the physical strength to use this handheld for more than 5 minutes. Thus, a good tripod is highly recommended. For exposures beyond the 1/FL shutter speed rule, I have gotten great results mounting the lens to my tripod in the usual way, then attaching a lightweight monopod to the camera body and allowing the extended leg to just make contact with the ground. This additional point of contact reduces motion noticably, and because you do not need to lock the monopod legs, it can accommodate quick re-aiming as required.
I love the gunsight notch in the top handle. I can rough aim the lens at my subject before turning on the camera, and it is nearly always lined up. It also works perfectly with my DIY solar finder and is already perfectly aimed with no adjustment required.
