Re: Pentax 50mm News

[Graywolf]

A microcomputer chip has to be zero defects (excluding memory areas where they 
can put in more than they need and map out defective areas) and they are made to 
much higher densities. Almost all imaging sensors have a few defective pixels. A 
full-size sensor should only cost in the vicinity of 2.5x as much as an APS 
sized sensor at similar densities and similar quantities. Which would put a full 
frame istD equivalent at about $2500. However why spend the extra as long as you 
can sell all the smaller sensor cameras you can make, and instead sell the large 
sensor camera at a 10x margin as Canon does.

However, I personally expect Pentax and others to produce full-frame cameras in 
that price range in the near future. Once one company does it they all will have to.

I know they're reaching their limitations, it's the same with computer CPU's 
they need a breakthrough, maybe a bit of lateral thinking - new materials - 
technology.........................


It does, it is small; it allows you to use all the old lenses; and it
has a viefinder rather than a dark tunnel. Plus the SD card wierdness
in the -Ds :-). Cost cutting is inevitable and they are offering a
botch^H^H^H^H^Hworkaround. Don't hold your breath.

Where did I put the MX, it's here somewhere :)

They'll come down a bit in time, besides you pay for the technology etc.

It *is* broke, check

It's a goner; do other manufacturers support it even in the way
Pentax does?
More cost cutting, it's about time Pentax stopped following Canon and 
Minolta
trends, they never where scared of breaking from the norm.
