Pentax 100mm F/3.5 SMC FA Macro K Mount Autofocus Lens {49} Description


Pentax smc P-FA 100mm F3.5 Macro Lens - f/3.5

The smc P-FA 100mm F3.5 medium-telephoto lens offers a focal length of 100mm with a 24.5-degree angle of view, allowing the user to capture close-up images from a distance. It features a maximum magnification of 0.5 times at a minimum focusing distance of 1.41 feet, making it ideal for outdoor macro photography, such as close-up images of flowers. As the front section of the lens barrel does not rotate during focus adjustment, it is convenient for the user to take pictures with accessories such as a polarizing or gelatin filter.
