Sounds like your decision is really between a 35 and 40 focal length. I opted for the DA35 2.4 because that closely equates to a "standard" lens for APS-c and delivers on the IQ front at a great price. While I am sure the 40ltd is a better quality lens I've never really understood why this focal length is made by Pentax as it equates roughly to 60mm on FF. I'm sure somebody will educate me on this!
