Best landscape camera ever - Tony Northup.
Tony's spot on. No camera can be the best at all possible applications. What's the problem?
The AF isn't up to par with Nikon. Pentax has work to do to catch up. It's a tad slow, but still usable.
Not surprised about the D-FA 2.8/15-30, but was surprised about the D-FA* 2.8/70-200. I got both my copies of this lens for free, so I don't really care.
FA Limited's, it's more about rendering than just sharpness (I have all three and love 'em), but the Zeiss ZK's (if you can still find them) are truly stellar in all respects, I recommend the Distagon T* 2/35 ZK and the Planar T* 1.4/85 ZK.
Just to add, for the Pentax K-1's very few minor shortcomings I still wouldn't consider anything else.
