Of the ten documented K-mount Vivitar 28mm lenses (yes, the full list will be posted here eventually!) there are only two which open up all the way to f/2. That's a stop faster than f/2.8, which can certainly make a difference in low light situations. But only if the performance is up to snuff. I've done a series of test shots to see if the K01 cuts the mustard. Read on for the third in the continuing series Looking For The Perfect Normal.
This is part of my series on Vivitar 28mm lenses. Before I get into the reviews proper, I thought I'd tell you how to set up your Pentax DSLR for older lenses. One of the great things about these cameras is the ability to fit any glass from the beginning of Pentax history to date. But prior to the age of auto-everything, taking photos involved a few steps you might not be familiar with. The article will cover how to fit an M42 lens, the camera settings you need to make, and how to actually take a photo.
