My name is John, and I'm a semi retired engineer from Auckland, New Zealand. I've been looking at this site for a while and finally decided to take the plunge and join, as I am getting back into photography as a serious hobby again after a while away. I currently have a Sony DSC-R1 which is capable of excellent results, but ofcourse is not a system camera and so I am going to build up a new system and am looking seriously at the Pentax gear. With that in mind, I have posted a question under the Lens discussion for your help, as I think there are a lot of experienced people here.
