Originally posted by D1N0 I never saw a need to upgrade from the K-5 (except to the K-1, but money....).
Yep, me too. If Pentax had never brought out the K-1, or if it hadn't been as (relatively) inexpensive as it was, I'd have stayed with my K-5 till it died. (Part of me being able to step up to the K-1 is that I had already accumulated a fair amount of film-era glass, including a classic 28-50-135 Prime trinity in FA series, and was ready to shoot it straight out of the box.)
But the K-5 is all the APS-C DSLR I will ever need, except when it comes to serious extension-tube or bellows work, and then I reach for my *istDS because of the analogue TTL protocol making the camera completely independent of receiving aperture or range-to-target data. Thank God Pentax kept the 49mm thread for so many of its primes, because *istDS + TTL ringflash = God camera for macro.
