Thanks, Mark—those links were really helpful. Given the importance of live view when shooting with a DSLR, converting my k7 seems like a better option—especially if working in urban areas. The k-5 is my back-up to the k-3, so I wouldn’t use it, but the k-7 I could and the extra advantage would be it is much smaller and lighter than my K10 and k20.
