SMC Pentax-A 50mm F2 Manual Focus Lens Review and Sample Photos
This is a fantastic classic manual focus Pentax lens. It's true that it's the slowest of the manual focus Pentax 50s, and was in fact the budget "kit lens" of its day. But what a kit lens! Times sure have changed for the worse in that department. While this may have been the slowest of the 50mm lenses offered by Pentax in those days, it's NO SLOUCH by today's standards. It's small and light, built quite well, and by today's standards is really quite fast (bright) at f/2.0. It's only slight too deep to call it a 50mm pancake - close enough in my book if you're looking for a small fast lens. And the best part is they are more common that fleas on a dog! Okay, busted, I'm exaggerating... but if you're the sort that's looking in thrift stores, eBay, or the used department of your local camera store - these show up all the time. My advice - especially if you're on a budget - is don't overlook this little gem.
LIKES: small, lightweight, well-made, reasonably fast by today's standards, easy to find, inexpensive.
DISLIKES: sometimes the aperture ring on these A-series lenses becomes hard to turn or even jammed up in their old age - it has to do with the button for the A setting on the ring. My local camera repair guy explained the weakness once and he's able to fix the problem. But I've encountered a bunch of these and most have worked fine. Just test the aperture ring out before you buy (if buying locally), or be sure to buy from a reputable seller if buying online). Also, we're talking about all the A-series lenses from Pentax from this generation - not just this one.
