The irony of plastic use in DSLRs and other cameras

What is the irony? The only part that would benefit from coming
technology that will see plastic as a suitable replacement is the LCD
which uses glass in it's construction. The only part of a camera where
it would actually make SENSE to use plastic, and it's not available!!!

 

Oh look Rich, your fly is undone!

 

Still riding that one trick pony, eh?

 

Glass is not a requirement, but it tends to be more scratch resistant.

A computer monitor is unlikely to be in contact with various objects
that could scratch it, while a camera tends to be placed against shirt
buttons, zippers, etc.

 

Glass is a plastic in the true sense of the word.
Hint, it was once sand, or something like it.

 

Actually it's a fluid - a very viscous fluid to be sure, but
a fluid rather than a plastic.

 

Oh do give it a rest Rich. Plastic plastic plastic.
Anything else?

Actually - that appears to be a myth:
http://en.wikipedia.org/wiki/Glass#Glass_as_a_liquid

 

I see he's also still confused about when to use it's and when to use its.
Poor bugger.

 

Well, not quite. I said it wasn't plastic in nature, but
fluid. The reference you cite says "different views can be
justified since characterizing glass as either 'solid' or
'liquid' is not an entirely straightforward matter" and
quotes a reference:
http://math.ucr.edu/home/baez/physics/General/Glass/glass.html

The conclusion says: "There is no clear answer to the
question "Is glass solid or liquid?" ".

It does appear to be a myth that glass flows, but that isn't
what I said. Either way... it isn't a plastic!

 

Scientifically speaking, ordinary glass at room
temperature is a solid, no quibble. There is a
clear change in heat capacity between a typical
liquid value at high temperatures to a typical
solid value at low temperatures. The transition
is not sharp, but still represents a phase transition.
My ex-colleague Peter Wolynes worked out the theory
of all this.

The new Leica is metal? But that goes without saying....

 

Is that why you bought one?

 

$6000 for a rangefinder camera and a limited selection of focal lengths
won't sell to very many people.

 

So it would not matter if it was made of wood, you are still not getting one
are you so just why would you care what it is made of?

 

bet they could make it cheaper if they used plastic

He doesn't. Just likes making threads.

 

Then lock him up in a tower with a spinning wheel... and no
internet connection.

 

The Irony here (Cue Alanis - it's like raaaaeeeeeeeeaaaaaaaaiiiiiiinnn)
is that you don't have a Digital SLR and yet here you are day in day
out.

Get a camera or get a life

Is it plastic?
