https://www.pentaxforums.com/gallery/photo-300mm-lens-sharpness-61536/I've been a Pentax user for over 40 years, but in the absence of stacking support for macro, have drifted to using a light weight, mirrorless Olympus (my confession, I lug my camera equipment on long hikes almost daily). This camera has internal (body) stabilization, like my Pentax K5. Increased distance to the sensor plane in this particular mirrorless camera series effectively turns the 300mm into a 600mm lens. I bought the lens in 2012 and its been banging around in my camera bag for many miles and years. I had it tightened up and cleaned in 2022.
I've always appreciated the quality of this lens, but always used manual focusing for wildlife photography, never even noticing that my trusty K5 had lost its ability to autofocus heavier lenses. I mounted my 300mm Pentax lens on the Olympus (20MB sensor, manual focus the only option) and was totally floored by its sharpness upon photographing a submarine across the Chesapeake Bay at a distance of about 4 miles (hand-held). This lens captured incredible detail of small paint markings and people standing around on deck. Too often people offer less-than-persuasive images of bird feathers from unknown camera-to-subject distances and under unclear shooting and handling conditions. This distance I knew - Pentax makes one incredibly sharp lens. You can believe those good ratings for this optical gem!
