Originally posted by Ron Boggs I recently sold the 67 M*400/4 EDIF for less than what a similar 400 would cost if available for Pentax DSLR's. Sold it here on this forum.
Also sold the 67 M*300/4 EDIF for under $1000 here on the forum last month. Even used, you may not find a DA*300/4 below $1000.
But you can find manual focus K-mount 300/4 lenses much cheaper than 67 M* 300/4. Many of these K-mount lenses will probably perform better than this 67 lens on K-mount camera.
K-mount 400/4 lenses are difficult to find though.
