Kieth:
I spend nearly 20 years in network and telecom technology. I still
remember the bravado about Free Space Optics and Fibrer Interfaces -
until it actually had to work.
You are so right on about "new software". That term STILL gives me the
whammies.
Somehow, Leica has got to Keep It Simple, yet excite their very narrow
market with Innovation.
Tall order.

Bob

Well, folks, that's what I call a rumour mill!!
Curved sensors: I'd thought about that, and decided to dismiss the
idea, because the sensors are cut from the usual flat block of silicon.
But it would be an interesting solution - especially as you would need
double curvature. However, if you curved the sensor, you'd need
optically different lenses, and you couldn't use an existing lens
without either some sort of software modification of the picture, or
else optical converter. And the latter might need to be different for
different lenses. Of course, as Minox proved, you can have film with
double curvature......
Steve: we prefer Zestril or Lansoprazole for reflux...! ;-) Since both
taste awful, I think we'd better stick with Reflex.... :-D
One serious thought, however: for its digitals, Canon have produced
quite a few EF-S lenses, mostly wide angle to about 90mm, to reduce the
problems associated with the large distance mount - sensor on DSLRs -
even APS-C size. It would be logical that Leica will need to do
something similar. That doesn't force the owner of older lenses to
discard them, but their performance will not match the EF-S pattern.
Incidentally, something not mentioned. Sensor size v viewfinder
brightness. David has commented about the viewfinder of his 20D not
being anywhere near as bright as his R8 or R9. With an APS-C size
sensor (22.5 x 15) the mirror is correspondingly smaller, and the
viewfinder needs correspondingly more magnification to get a reasonable
picture size, so inevitably, fundamentals being what they are, the
image is dimmer. And there's nothing you can do about fundamentals!
That alone might be a good enough reason for Leica to go to a
full-frame sensor. I would sound a cautionary note about a larger than
full frame sensor to give IS electronically: for 'electronically', read
'software'. That word should make us all a bit twitchy! Unless they
have access to a well-proven algorithm, they could just catch a cold;
now here's a thought: it would be logical to go that route if they are
collaborating with one of the other manufacturers, so as to tap into
their experience. After two and a half decades involvement with
software reliability and safety, I probably hear the alarm bells sooner
than most; but suffice it to say, been there, done that, got the
baseball cap, tee-shirt, and sunglasses.....and a nervous twitch when I
hear the words 'new software'.
I guess we'll all go back into hibernation soon, until the next prod of
the rumour mill....
Cheers
Keith
