Generally, kit lenses are temporary place holders for better quality glass; something to use while an upgrade is pending. This past week i’ve changed things up, and relied exclusively on the PEN Mini kit lens, shooting exclusively in the 28mm equivalent focal range. At f3.5 (though i used f4 mostly — found the half stop making quite a difference in the IQ), it’s a relatively slow lens, but very usable in most available daytime light conditions. I was very surprised at how sharp the lens is at f4.0 and at f5.6, this sharpness extends from corner to corner quite well. Not your average kit lens, this. Very pleased.
