Appr. 100 USD. They are absolutely woth it. They don't degrade the foto's recogniseable - except you need longer exposure/larger aperture. The optical quality is excellent - or more correctly - it's simply brilliant, actually!
I paid 60GP for mine - which turned out to be one of the very best optical investments, I ever made. Of course the lens used along with it (best with primes) is equally important. I use it a lot with my M* 4/300mm, K 2.5/135mm and K2.8/105mm which are all excellent SMC Pentax lenses. I can give this tool my best recommendation any day.
