Originally posted by Emacs In Moscow many pentaxians switched to FF canikon (not cropped ones, of course).
They spent much on pentax lenses, they had large lens sets
They switched to FF and now spend much for canikon lenses, so, Pentax lost much. It's about thousand dollars at least
When they were switching they selling a lot of pentax glasses, so losses for pentax again
It's my advice to you: don't measure the profit on the camera only. DSLR means lenses too. Who spend much on camera, will likely spend much on lenses.
As for me, I would buy UWA lens (about 12-15mm), fast 135mm prime, and 24-70,70-200 f2.8 zooms.
This is a contradiction.
Either the supposed FF purchasers want to use their old glass OR they are gong to invest in new glass. They may do both, but there is no guarantee of that. Unfortunately, if you are at the sales end of the company, you need to know that decisively before the thumbs up.
If you don't measure the profit on the camera, and lose money on the body because someone wants it at a discount to use legacy glass, then Pentax corporate is subsidizing that consumer.
Legacy coverage depresses new glass sales. Nikon has seen this with their long FF zooms. It took them ages to update the line and their reason was because so many people continued to use existing product.
Unfortunately, in order to guarantee a revenue stream a manufacturer must have those added sales. They cannot take that subsidization risk.
One company that this issue drove into near-bankruptcy was Leica. This is why their bodies are so expensive to begin with. they *must* make top margins on their bodies because of so much quality legacy glass out there. What is rescuing Leica now is the switch to digital and the opportunity to make new glass optimized for that purpose, compelling new and existing buyers into added sales.
The Nikon FF sensors were designed by Nikon. Sony manufactures them. The thinking is Nikon invested capital into the fab as part of an agreement as the companies have long had a close relationship and a common enemy in Canon. This happened at nearly the same time as Sony dropped the A850 FF camera. Speculation is Sony had to make a choice about being an industrial supplier to Nikon or continuing to make their own inferior chips at a loss. Sony Industrial won that argument because, despite hoards of excellent Minolta FF legacy glass and customers out there (much more than Pentax), Sony FF sales were awful. That's a lesson for Pentax; all the legacy customers you have who might want to switch is not enough to go to FF profitably. In order for Pentax to go FF, the costs of the sensors and design have to come down substantially.
Do not forget that Nikon Precision has a senior position in the lithography business and supplies Sony (and Intel, and others) with equipment. Apparently the D4 will also use Sony manufacturing to Nikon spec and that Sony will use the same sensor in their FF pellicle in 2012. The Sony A900 sensor is supposedly similar to the D3 sensor, but Nikon engineers crawl all over the facility in production. There's a whole lot more the sensors than just the array; there's the FPS issue with dumping at high frame rates and the AF system necessary to support that. There's video. There's power. Have you seen the physical size of the K-5 SR and AF systems? And the SR system? Pentax has no AF system capable of competing. It has no lens array and is years behind in development for FF.
FF is a very small market with extremely limited demand and high, high costs. The market is so small that Sony has put more weight into the industrial supply of its consumer competitor Nikon than into supplying its own consumers within the unified brand. That decision alone speaks volumes about the breadth and depth of the market for DSLR cameras over $2,000. Canon makes their own sensors and does pretty much everything in-house for their top-end DSLR's. The FF market could benefit from a third company getting into the race and helping drive down costs, but that company will not be Pentax; it will continue to be Sony itself.
Then there are the disruptors: mirrorless and pellicle. High-ISO sensors enable pellicle and K-mount backwards compatibility in the conformist SLR form factor; but mirrorless creates a new form factor allowing for smaller systems, but likely at the expense of K-mount compatibility meaning a whole new mount and a costly adapter for legacy users. Pentax is very wise to wait and see how those issues play out before leaping. The FF sensor issue will play out at lower costs, just over time measured in years. In the meantime, APS-C becomes more of a commodity and makes it harder to differentiate systems and brands. The moment Canon says APS-H is the "new APS-C" is when the market changes and sensor size becomes a driving force in new consumption.
