Latest Review Posted | SMC Pentax-FA 100-300mm F4.7-5.8 I've had this lens for about 10 years now, and it's still holding on great. The focus ring is a little loose at this point resulting in an unsteady focus, but other than that it works great on the K-r. It's a fairly slow lens, and with the K-r it runs into autofocus problems under non-ideal lighting conditions, but manual focus is quick and easy. Images are sharp, but do suffer from aberrations (though easily fixed in software). It has a plastic-y feel to it, but is fairly solid nonetheless, and for the size it's very light. For the price, it's definitely a great lens to have. Here are some example shots:
