I have a friend who works at pentax and we had a conversation shifted to full frame cameras, he didnt answer my obvious questions for pentax. That was a year or so ago. Met him again and asked the same question, he just smiled and changed the subject... could this be a yes or a no? Maybe this year's Photokina, we'll all know the answer to that...
If I was a pentax employee I would ask for a dollar each time someone asked me about FF (My get rich scheme ). With all respect he probably has no idea. Things like that are generally kept to a need to know basis even parts manufacturers are probably kept slightly in the dark about components they are making. The old "Those who know don't talk, and those who talk don't know." adage is very applicable. I would say Pentax is one of the better companies at keeping secrets, like the new X-5 only really leaked a couple of days before it was announced.

That should be a Yes, or never talk to him again!
hahaha. I'd do that!

I think you should change the way you ask him questions, he will smile for a good reason then
He didnt smile the first time I asked him though, but only on the second time. Maybe it means something, maybe it doesnt. I'm still excited to see what they have in store for us at Photokina.

Actual secrecy is on average a function of how many people know. With Pentax, that's a lot less than Canon.

This close to Photokina, the leaks are large and constant, but if you don't know, you can't tell dreams from reality .

Yeah that is true, plus add a few clauses in employee contracts with some hefty consequences for those who are in the know to ward off the "honest" whisperers and leaks dry up pretty fast.

Actually that idea has been around a while (probably not externally publicized though). My university was advertising it for a few months back in 2010 on it's web site as they have a few research papers on it.
Electromagnetism: does its strength vary across the Universe? - Swinburne Research Bank : Open Access Repository
Thanks CR

PS: Reading the 'Abstract' on that page I can't help wondering if the gravitational mass of the universe itself is the driving force for the existence of EM anyway. I realize they are [supposedly] two different things but it may be possible the EM is the release valve of the universe .. a naive view but I thought it worth mentioning.

PS2: I expect that all matter will be found out to be a form of EM soon enough.

Hmm upon more research I think i was wrong saying 2010. This was the article I was referring to, which dates Oct 2011.

Yes, that was what I read I believe. Fascinating!

It means he likes you better after the nice bottle of wine you invested in his discretion .....

There were FF Pentax rumors long before the 1April joke.
Was there ever a time when there wasn't Pentax rumors?

b) what can be done to small sensors can be done to large sensors, too. So they'll always have advantages.
Technically of course.
Practically not. Of all kind of reasons being mostly price and ROI. Otherwise every digital MF on the market would go to 51200+ Iso. So this is true but should be put in context (unfortunately I'd say).

APS-C is, for now, at a sweet spot from a tech PoV (getting tech from small sensors rapidly, and evolving fast). FF less but size of sensor compensate somewhat for it (new FF sensors kills the competition, but 2-3 years later gets competition from APS at low ISO). MF though... slugish is stuck with ... CCD

All I wrote does NOT take into account any photographic/optic difference. I know bigger is better, this is NOT the problem here.

Straight face at first. Second time, a smile. Do we see a trend here?
Next time, he'll laugh his a**e off

I read a news report yesterday (somewhere) which stated that measurements seem to indicate that the laws of electromagnetism might well be very different in the far reaches of the universe. So it's possible that the laws of nature may not be as immutable as we thought.
Physicists never think or even claim that laws of nature are immutable.

It is their profession to try to alter them, their raison d'etre. That's why they try to stay as open minded as possible -- without however becoming dreamers

Now, to assume a constant actually is a field is common business in physics. So, variations of electromagnetic coupling constant (alpha) or gravitation are constantly being hunted for. If alpha turns into a field, physics would change and progress would happen. But in a way that current laws become special cases which still remain valid. No hope for photographers believing into magic

As for the work of Prof. Webbs (and this is what was addressed in the article you have read) ... his probably most recent publication is
-> http://arxiv.org/pdf/1202.4758v1.pdf

Please, refer specifically to Fig.8 and Fig.14. And decide for yourself. I never trust second sources when it comes to such things. Let me say this: Not all researchers are convinced about the conclusiveness of results. I share the doubt. Esp. as results of two observatories are combined and "by accident" one sees one side of the postulated dipole (of pstulated alpha field) and the other observatory sees the opposite side. That triggers my alarm bells.

Unfortunately, media have more recently adopted a policy to report about premature research results from physicists. I only say magnetic monopole, cold fusion or faster than light neutrinos in Italy. IMHO, this includes the Higgs boson discovery (which I think is real but results are too premature to be released to the grand public) and various studies about variations of coupling constants.

Of course, it is all entirely ff-topic here

Fantasy and imagination (dreaming?) are important to all areas of creative human activity and to assume that good science exists without such is a fantasy in itself.

Please, don't twist my words. I think you know what I meant.

I explicitely used the word "dreaming" and not fantasy, imagination, or more importantly, intuition. E.g., Einstein did not dream curved space time, he had the intuition to understand that the equivalence principle has a deep impact if fully thought thru ("what is a straight line near a star?") and sought for the mathematical assistance (tensor analysis) to work out the difficult details.

The difference between (physical) science and dreams is that science takes a guided tour through the space of all imaginable things, while dreams take an unguided tour. And more importantly, sometimes, the guided tour eventually reaches unimaginable things.
