being a pentak owner (k1000), i think the most diff thing abt using pentax system is finding gd lenses. There are plenty canon, nikon & even minolta lense, but penatx has a small collection here. Just look at Cameraworkshop, very few PK mount lenses, sopmetimes it take lotta of effort to buy online frm ebay
but nonetheless it's a gd system!
