Wheatfield hasnt lost anything.
and thanks for asserting to us that you did nothing more than jump on the "APS-C is the future, down with the communi-err-full framers!!" bandwagon.
Firstly, you don't need to refer to me as an idiot. I don't believe the number of posts I've made on this forum has any correlation with my understanding of photography.
My point remains simple: Full-frame makes sense for Nikon and Canon. They have a large line of lenses in production, and can easily support producing two dozen lenses.
Pentax cannot.
Showing me pictures of all your old taks and 3rd party MF lenses doesn't provide a single reason why Pentax should manufacture a FF camera.
Yes -- FA and FA* lenses look great -- but most of them are out of production. Didn't you get that memo? That means Pentax doesn't make a cent for ANY FA* lens sold.
How would you go about marketing that?
It would be like if Canon went to APS-C with their EOS system -- and then years later came out with a full-frame camera that took advantage of full-frame FD lenses.
Sure, lots of people have old full-frame lenses around (and the first line of limiteds are all full-frame, I'm aware)
But, Pentax CANNOT release a full-frame camera unless they are currently producing a line of full-frame lenses! How could ANYONE disagree with that statement?
That's why this argument seems so ridiculous -- it would be SUICIDE for Pentax to produce a full-frame body.
Whenever I picture a fictitious product, I try to figure out how realistic it is by picturing what the product manual would read like.
"The exciting new Pentax K3D features a full-frame* sensor, for the ultimate in image quality...
*full-frame sensor only supports legacy FA lenses."
...Even if the engineers came out with a design, the marketing department would say "oh hell no"
And then you bring up ridiculous statements like, "some of the DA* lenses cover full-frames at narrower apertures and longer focal lengths"
....I was giddy like a little child when I read that. You initially wanted full-frame so you could get less depth of field (because obviously, that's the ultimate mark of a good photograph...?)
...so, you'll get your full-frame camera, slap on a DA* 16-50, and say, "oh, it works great at f/8.0 and above -- and you can't zoom out further than 24mm"
....so, you want a full-frame camera so you can get razor-thin depth of field. But you'll have to shoot at f/8.0 or higher on almost EVERY lens in production?
And, again, how would Pentax explain that in the manual?
"The following DA* lenses may be used in full-frame mode:
300/4 at all apertures (vignetting may occur)
16-50/2.8 at 24.5mm or greater, at f/8.0
50-135/2.8 at f/4.0 or higher
12-24/4 at 19mm or greater, at f/10"
I'm completely making up the numbers -- but that's essentially what it would be like, right?
That is one hell of a hack, if you ask me! Professional photographers wouldn't spend a dime on a camera that requires so much explanation to do anything.
If the situation was different, and they had a full line of full-frame SDM lenses, then obviously, a FF camera would make perfect sense.
Hell, I'd buy one.
But that's not the case. That's why the argument is ridiculous.
You need to look at the situation from a business/marketing point of view -- and not just from the perspective of a photographer who needs even thinner depth-of-field.
By that argument, why shouldn't Pentax make a 90mm f/1.0 lens?
It's POSSIBLE. Companies have made them before. BUT, they're outrageously expensive -- they would sell very few of them, and the R&D costs would be prohibitively expensive.
Now, I *have* advocated for f/2.0 or f/2.2 zooms from Pentax for people who want depth-of-field characteristics similar to film. Falconeye and I have mentioned that as a wonderful solution to the "problem" of too much DoF that you're heavily burdened by.
But, even then, Pentax would have to determine if there's a market for it.
Canon and Nikon have 400/2.8s -- why doesn't Pentax? No market.
It's really that simple.
And stop with the personal attacks. Thanks for your understanding.
