At my wife’s urging, who has had great success with finding handbags on ebay, I found and purchased the last 2 lenses I was missing at each end having covered all needs in between. A wide full frame lens (manual focus is no hardship with wide lenses) and a full frame 300+ AF tele lens.
A wide MF is no big deal, but for me AF is necessary for tele.
Together they cost $229 less than the Pentax 28-105mm weather sealed lens (a fine lens that I just so happened not to need) I test drove at SE Camera last week.
I am finding that the Pentax K-1’s secret weapon is legacy SLR film glass owing to reverse compatibility back to 1975. I will provide an update when they arrive in the upcoming weeks.
