Please forgive my ignorance...What is full frame?

[and]

1.5x/1.6x = APS-C/DX
1.3x = APS-H
1.0 = FF / FullFrame / FX

These are crop factors, what are crop factors? See below

Or in simpler terms it means the sensor would be the same size as a 35mm negative.

Please forgive my ignorance...What is full frame?

i'm seriously thinking of investing the $ in a da*50-135, but i really don't like the thought of getting something this expensive that will become unusable when full-frame (eventually) comes to pentax.

Yes, it will become a doorstop - just like all 24x36 "full frame" lenses will be doorstops when Pentax finally release the 645D camera. You can't use 24x36 lenses on the 645D, and not even APS-C lenses. This really scares me. 24x36 lenses will drop at e-bay and those with 645 lenses are actually sitting on a goldmine that they can sell to all those who will sell all their 24x36 gear when digital medium format enters the market at a price people can afford. There is absolutely no future in 24x36. As we all know "the bigger, the better it is". Imagine noise levels at high ISO on a digital medium format... wow! This is what all photographers wants. As we know, there is no room in the market for different systems. We will all be using digital medium format in the next few years, it will become the new standard. Those makers that are not investing in digital medium format will all be dead and buried by then.

Ah, I thought "full frame" simply menat lenses and sensor filling the same frame without gaps.
That is - "full frame" = APS-C lenses on APS-C bodies, 24x36 lenses on 24x36 bodies, medium format lenses on medium format bodies.

And "crop format" meaning when the lens and sensor does not match.
Like using medium format lenses on 24x36 bodies, using a "cropped" format on a "cropped" sensor (the 24x36 sensor).

Forgive me, but I can't tell if you're being facetious or not. There is just no way...do you realize how big lenses have to be to fit MF? There is a reason MF did not take over 35mm film. At least I can hand-hold a 35mm camera. My Hasselblad? Not so much.

I'm pretty sure RMabo is being sarcastic..... They really do need to come up with an official "sarcasm" smiley

I'm pretty sure my 50-135mm will still work on my K10D if Pentax ever releases a full-frame camera.

I would rather Pentax channel their resources into the 645D.

Don't get me wrong, I love medium format.
I'm using one more than my Pentax at the moment, and will probably buy it in 2 weeks.
However in my opinion it's such a small market that they'd be foolish to go forward with it until they get all their finances straightened out.

That is why 645D is delayed to be released again and again. Probably a suicide product for pentax company. Besides, a MF body might even be released without a DA 50mm f1.4 to match it even if 645D were offocially in the production pipeline.

Still, really desiring to own one

I guess so...at least for the dense ones like me...

[mattdm]

It'll be smaller and lighter than any full-frame replacement. For this reason, I think the current-sized sensors will still have a place even in a full-frame 35mm world.

is there a full-frame alternative available that has the same optical magnificence?

cheers.

Absolutely the answer is yes it will.

When Pentax releases a camera with a 35mm sized sensor (I am sick of the term FF for 35mm format sensors), you can send your 50-135 "doorstop" to me

if you are concerned about it becoming obsolite, just sell it to one of us who is converted to the ASP-C sensor.

I'll take it off your hands

Of course it will. Thats why I got it. It matches my Green and Gold interior. Didn't you know that. It's sooooooo in VOGUE!
