How much of the cost and weight of a professional, top of the line, "flagship" camera comes from designing and installing environmental sealing?

Hi,

One of the most well protected cameras is Pentax K5 and it is very reasonable priced. So I would suggest that weather sealing can be done at pretty low cost. The same applies to weight.

Best regards
Erik

 Grin Funny but good question. I am sure that it isn't the ~ $3k Canon/Nikon ask for in additional cost. Tongue

Realistically, in comparing the sealing of something like a D700 with a D3, the manufacturing cost difference is negligible, especially if you got rid of the pop-up flash on the D700 which limits their ability to seal it as well. The additional O-rings might be about $10 (likely less). Adding more channels to the case for the O-rings is nearly free, but depending on how intricate the casting is, they may increase the reject rate, which has a cost. Lastly, the design cost needs to be recouped. As long as a manufacturer insists on having a finely incremented product line (many products spanning very small price segments), the extra design cost may be non-trivial. However, reducing nearly redundant models through more modular designs could easily more than offset this (the accessory treadmill, where nearly every new camera has a unique battery and vertical grip).

In the end, when comparing a model like the D700 to the D3, we may be talking about $50 per unit. If we are talking about something like a D3100 vs a D3, then it is likely around $200. I am thinking about internal costing here.

In terms of weight, it is nearly trivial. We are talking about maybe an ounce of O-rings.
