Originally posted by quant2325 Pentax has what, a 2% market share? A substantial number of Pentaxians currently using anything from a K-5 to K-3 are waiting for the FF. Some of those cameras will be sold to pay for the FF. When unit sales are so low with a brand like Pentax, 500 K-3 cameras being dumped on the market will quickly drop the price. If even 20 go on ebay you will see the price significantly drop.
I have to admit, having a K-5 (not II), I wonder about getting it upgraded but I, presently, am more inclined into going all the way to Full Frame although lenses above 50mm will need replacements (such as gem 50-135).
Financially I can't justify it but FF + Samyang shift lens may be a credible alternative to 4x5 film vue camera.
