Personally, I think professional camera is the one you use to make money with, be it D3200 or D800.

Vacuum at -200ºC makes no sense. Temperature is a physical property of surrounding environment (or material object), and since there is no surrounding environment in vacuum, there is no point in...

Hα-filter allows transmition of light only in that bandwidth.
Common infra-red filter in cameras blocks most of it.
So if you put that filter on common camera, you probably won't see much.

I believe it's plastic. It definetely comes in black. And, as far as i know, has exactly the same optical system as 40mm limited (and SMC M 40/2.8), maybe newer/better coating.
Personally, I...

Guidenet, actually, K-5 is top level crop camera. As for FF, Pentax needs it as much as Canon/Nikon needs MF.

Yeah, and how did they remove people sitting still on Eiffel Tower Photo?

I'd prefer 645D anyday just for their MF lenses (old ones, if you can call them old). Wonder if there'll be a replacement anytime soon.

Not sure, but those reasons seem not true to me.

Nothing. Here's what my Merriam-Webster also says:
b : "transmitting and diffusing light so that objects beyond cannot be seen clearly"

Antisthenes, actually, translucence is the property of some material to allow light to pass through diffusely(!). Like not very clean water or fog. Doubt, that they use this kind of mirror there.

I don't think their lens were made for your kind of work then.

But they don't need wide aperture for that. I mean they used low ISO number and narrow aperture. Some of them even had film camera with 25 ISO film in it. And they always could use polarizer as ND...

Why would landscape photographers want wide aperture with slow shutter anyway?
I haven't seen any of them even with simple ND filter, many with gradient filters, though.

Aha, so as Minolta users, but wait.. there's Sony now, who needs them now anyway? Aren't they a bit too late also?

And most 645 users were using 645NII. Why do you think it was in production till...

Nice portrait. Reminds me of Gimli, played by John Rhys-Davies

I too don't understand why is everyone like "Oh, no! Pentax is doomed! We all gonna die!"
Look at Sony that bought Minolta and making some nice cameras now.
And Ricoh have the means to make this...
