Originally posted by elliott I don't think you quite understand how economies of scale work. This camera would be a very specialized device and would be outsold by the standard model by 1000:1, at least. It would be more expensive than the standard model, not cheaper.
To be clear, the cost of developing and producing a robust physical casing is quite low. Remember, there are far fewer openings due to removing the screen and physical controls (which could really be limited to an on-off switch and battery door). Removing the buttons, screens, prism viewfinder, etc removes a significant amount of cost. The result is a monolithic type casing with a lens mount, battery/sd card door, on/off switch, and maybe a hotshoe/external power.
My cost estimates:
Development
1. ~$20-30k for development and prototyping of a milled plastic/metal body casing
2. ~$100,000 for polycarbonate body mold and production line jigs
Production
1. Body cost of about $5 (polycarbonate is cheap material) - maybe 30% of the cost of a K30 body and all the doors, etc.
2. Assembly and Quality Control cost of about $20 - ~25% of the cost of a K30. This is a much simpler body.
3. Bill of Material (BOM) for battery/electronics-PCB/imaging sensor/ae/focusing ~ $150 - ~75% of the cost of a K30 BOM. Would use all of the same electronics and imaging components as the K30.
Figuring a production run of 10,000 pieces, development costs are ~$15 per body. The production costs are ~$175, or about half the cost of a K30 body. So, rounding off, Pentax could produce these bodies for ~$200/each - on the same production line as the K30.
Figuring a very handsome profit margin (better than the K30), Pentax could still sell the MonoK30 (ie the robust remote body) for $200-$300 less than the K30. At 30% smaller volume and dimensions, it would be instant buzz and instant competition for HD Hero/Pro type cameras.
Would a $500 MonoK30 'remote imaging' body with Pentax K mount be attractive to many photographers and videographers? I think so.
All in favor say 'aye'!
P.S. This is getting away from the embedded wireless elements so I'll post the MonoK30 as a new thread.
