fenceSitter: DPReview about the Pentax 645Z: "the larger sensor area does mean more light is gathered than comparable full-frame 35mm DSLRs."

I'm afraid this is patently false. Pentax's fastest medium format lenses are so much slower than those available for full-frame DSLRs that it completely obliterates any light-gathering advantage that the larger sensor might otherwise have.

To wit, a full-frame DSLR sensor behind a lens @ f1.4 gathers more than twice as much light as the 645Z sensor behind a lens @ f2.8, and f2.8 is the fastest there is in Pentax's current 645 portfolio.

@pannumon: how is that f/t-stop determines the shutter speed? My camera allows setting them independently.
Of course, it's the physical aperture that collects the light. So the equivalent lenses with the same physical aperture collect the same amount of light, etc. etc.

The process is too slow and laborious. Some macro enthusiasts may use it for focus stacking, but I doubt there will be materially different from zero percent of users who would care to use it, especially when there aren't any compelling applications.

I would suggest they do it differently. They need to do focus bracketing in the vicinity of the focus point. That would allow to fix those infrequent focusing errors. It will also be a lot faster.

Are they liquidating? Amazon started selling the B5-0035 ILLUM for $399.99.

forpetessake: Sony might have made the most technical advances. But in the end of the day it's the pictures that matter. And honestly looking at all those samples it's hard to deny the two Canons the most pleasing colors and tonality, far better than Sony.

Looks like some people live in a fantasy world thinking they can get any color rendering from any camera as long as they shoot raw.

"...disservice to representing accurately what your eye has seen" -- that's a frequently repeated myth. In reality human color memory is horrible! Nobody can ever tell "what the eye has seen." That's what every research shows. People always choose pleasing colors, not the accurate colors -- even if they wanted they wouldn't know what the accurate colors were.

mailman88: Just think....the pro's once used Canon's 10D and 20D. Got great results and made plenty of money.

What's your point? I've used 8MHz 640K computer at the time of writing my dissertation.

forpetessake: Even though the foreground is very close to the camera and background is virtually in infinity, the automatic separation is pretty poor and defects are visible even on that small picture. The PS mask would do a better job in not much more time. And, of course, in real work creating a mask is the simplest of the tasks. Getting the lighting and colors consistent is more difficult.

Looks like Lytro is still looking for an application for their product and have hard time finding any.

It seems to me the separation errors are significantly larger than could be explained by the low resolution. Now imagine, if that little dude wasn't wearing a cap, his hair would have been unattractively separated from his head :-)

alatchin: Interesting, as a great deal of this is software based Panasonic's new post focus feature which can use peaking style overlays could be used in a similar fashion... I think Lytro's best chance of success is their new virtual reality... imgine combining pupil tracking with focus for an utterly convincing Virtual Reality environment.

Lytro won't go far in any reality until they solve the low image resolution problem.

Enough resolution to crop. So for many practical purposes it's as good as 35-70/2.0-4.0 zoom.

ThatCamFan: My interest died because of the megapixel count, a 16-24mp rx1 with the af improved would of been a must have for me.

Are you having problems with too large files? Then just switch the in-camera resolution to lower setting. I'm sure this camera just like every other has a few menu selections for output resolution.

I have nothing against people inventing various even wacky ways of entertaining themselves and battling boredom. But when they start promoting myths of some noble, eco-friendly, peaceful primitive savages, it's time to set the record straight.
Ignoble savages were nasty to one another as well as to their environments. Surveying primitive and civilized societies, University of Illinois anthropologist Lawrence H. Keeley ... demonstrates that prehistoric war was, relative to population densities and fighting technologies, at least as frequent ... as deadly ... and as ruthless ... as modern war. One pre-Columbian mass grave in South Dakota, for example, yielded the remains of 500 scalped and mutilated men, women and children. (Michael Shermer, Scientific American)

In reply to:

noyo: If you haven't already done so, perhaps you should google 'world's most expensive photographs' and take a look at what is valued as collectible or investable in photography.

What passes as art and the value placed on it, for me, is somewhat jaw-dropping - flat, uninspired, poorly photoshopped, vacuous and not necessarily original.

The clue here is that art is not about the best/most expensive gear, the best technique, best composition, prettiest subject or scene.

Simply owning a camera or taking photos doesn't make an artist, just as owning a football wouldn't qualify us to be a professional footballer or referee. It helps if we have a range of good skills and knowledge about the game.

Perhaps on order to make, understand or judge art we need to know about it, the industry and what passes as art, although we can all certainly shout from the touchline or from the comfort of our chairs.

"If you haven't already done so, perhaps you should google 'world's most expensive photographs' and take a look at what is valued as collectible or investable in photography."

Yeah, the upside down airplane postage stamps are collectibles and very good investment?

The truth is that the definition of art for gathered here photography enthusiasts and art collectors or other groups is not the same. And there is no merit in imposing one group values on the representatives of the other groups.
