Thank you for your lovely comments on my Pentax camera story. It sounds like your Father was a real Pentax user like my Uncle - you inherited quite a cashe! I read some of your threads, you sound like a very experienced photographer. In my case my Dad didn't have background in photography and my Uncle lived out of town. I have been learning on my own with the help of library books and the Forum. I look forward to learning about lenses and what to buy. I inherited the Ashai box lens and a S_____ 135mm lens. I want to replace the box lens and buy a wide angle lense (?) for tight shots getting more of the shot in the picture. I would like to buy the best lenses that I can and like you I am willing to wait. I hope you are still enjoying your K-5. Do you think there is a lot of difference in the senors of the K-20 and K-5? I will consider buying a K-5 if there is a significant enough of a reason to.
