Originally posted by monochrome I am absolutely convinced, with absolutely no knowledge of Ricoh or of the market, that to succeed financially a FF dSLR must gain significant USA market share and volume. In order to gain such, the manufacturer must commit to lose millions of dollars on USA infrastructure, advertising, endorsements, pro support and B&M presence - just to encourage wealthy enthusiasts to enjoy status by association buying the camera - and then making it up downstream on low quality 'halo effect' consumer cameras..
IM imaginary HO Pentax decided with the LX that it would not make the investment, and thus discovered it would never truly succeed in the professional market. Consequently it began dismembering altogether the USA distribution infrastructure, which has proceeded to its logical and ridiculous extreme today.
Look at Pentax distribution infrastructure. Look at Pentax product structure (the quality). If my suppositions above are correct, given the condition of USA (and now EU and Canada) infrastructure and the high-quality consumer cameras, there will never be a K-mount Pentax FF dSLR.
That isn't to say Ricoh will never release a FF camera - but a FF K-mount Pentax dSLR just looks impossible to me.
You are so right... If you have 645z (and add some LONG/ Large Aperture lenses), why would one launch FF for a small segment. What the enthusiasts on this site don't realize is "pros" have been using and will continue to use High-res APSc cameras everyday. When they speak to each other, they look at IQ and toughness, not sensor size.
AdMen use MF/ specialty for products, Newspaper types use fast low res "pro" bodies for speed NOT IQ, doesn't matter in printed press delivery (above 16mp).
Birders want the APSc crop AND a 24mp sensor. If you put a 300mm f2.8 on it (with a converter or not) tons of reach. A roughly 250-600 F4 or F5.6 would streamline many kits. Financially challenging, though... If they have FF glass, they are in the middle of the image circle (questionable value, although theoretically better in the corners, lots of debate on the real life results though...), if not ,birders buy the best glass they can afford.
Sports pros use fast med res with BIG glass. Cost of entry for them, hence not a lot of Pentax equipped sports photographers. It's all about the glass... They beat it up, and there is not a current Pentax offering to replace it from every 4 years.
I have never (in 40+ years of working with pros of any flavor) heard a true "pro" (especially a journalist) wax lyracally about brand. A Lens... Yes, a Tough body...Yes, support network/ spares... Yes. FF vs APSc, a fantasy from those that don't make a living at it, or those that need to go wide. As delivered by Canon and Nikon (except the D8xx), are lower res, tougher, fast to cycle.
I knew AP photographers in the 80s using Mamiya Sekor 35mms. Newspaper photographers using Pentax and Minoltas because they were lighter.
Pentax's long delay to AF cost them. Worse yet, Asahi designed the firsr AF capabilities used in MOST of the other cameras. Wrong time to be a fast follower, as opposed to the R&D leader (of the 50s, 60s, 70s)... They started to slide when the LX wasn't as tough as the Nikon Fs. Beautiful finishing and high end optics were not needed in the global battlefields, Hence Nikon won. Sux, but history. Hell, Canon was hanging out with Bell & Howell. Ouch...
To be irreverent, I cannot fathom the groveling for a 70-210 (etc) FF FA* lens. Buy one on eBay. Had one. Became obsolete on K-3 with the 60-250. Old news. They are great workhorses, but it is a 105-300 on a K-3. Whats the big deal for a NEW one? IMHO the lighter, better coated DA*s work fine (had a 16-50 SDM blow,no biggy Pentax/CRIS were great.) Otherwise steller. Just spent a week in 110 degrees in the desert shooting. I'll take a lighter, non metallic DA* with updated coatings ANYDAY...
We don't need no stinking FF DSLR...
Just long tele zooms, great coatings, big glass for 645z, and throw in a cheap 24MP FF ILC with an OVF to use all of the great older FF glass...
