You must have some relationship with Ricoh then ... and that amazes me that it is way out there in Slovenia.
Make sure to keep feeding us on the rumour ... we like that here!

It even has one of my favorite lens on it: the 43mm Ltd in silver.

I always told myself that if Pentax released a full frame camera I would buy the FA43 with it. Maybe they will offer it as a kit.

Linear resolution is meaningless as images are not one-dimensional.
The ability to resolve detail is determined by whether or not you can distinguish a feature from something directly adjacent to it. This means that the only thing that matters for resolving power is the linear separation between one detail and any other detail, i.e. one dimension.

For instance, the ability to resolve two lines parallel to each other, the only thing that matters is the perpendicular axis between them. Lines of pixels along the parallel axis are useless because they are along the lines, and do not separate them. If you want to clearly resolve lines that are twice as thin, you need to double the linear resolution, which is four times the pixels (assuming square pixels). This applies to individual pixels as well, lines are just easier to visualize (you can think of pixels as very short lines running in a direction perpendicular to the axis between it and the pixel you are comparing it to). The only thing you need to distinguish one pixel from any other pixel is the line of pixels between them. Pixels in any other direction are not necessary.

There is a reason why print quality is given in DPI (dots per inch) or PPI (pixels per inch), and why astronomers state the resolving power of their telecopses in terms of angular resolution, which are all single dimensional units. This is why you cannot believe that marketing nonsense that 4K UHD (3840x2160) is "four times clearer" than 1080p. 4K will only resolve twice as finely spaced details as 1080p, with four times the total pixels.

No one except pixelpeepers (litterally) look at images this way. You look at whole image at the same time. Images fills an area. It is the total quality of this area that decides the quality of the image. Resolution happens in more than one dimension.

Ummm yea...
I don't remember reading "image quality" = resolution.

You could've said that resolution is not important to you and that would've been a correct statement.
Trying to change the definition of a term makes what you wrote incorrect.

Yes, I'm sure all those film scientists and astronomers who determined that the proper way to measure resolving power of film and optical systems was given in terms of single dimensional units (e.g. lp/mm and radians/degrees respectively) long before the concept of "pixels" was even invented were all "pixelpeepers"...

The bottom line is that if you want to perceive twice as finely spaced detail or go from 100dpi to 200dpi in your print, doubling your pixels does not get you there, while doubling the linear resolution (quadrupling the pixels) does, and that is the relevant factor in perceived resolution/sharpness.

Anyone is a pixelpeeper after a new lens acquisition. At least.

In short, Asahiman says:

- No FF this Photokina. Don't expect it.
For the record, Asahi Man said there would not be FF body on display at Photokina, but there might be information about it.

"The Pentax fullframe Body is not to see @ Photokina this year.

Maybe any informations,but we will see no body.

The next lens should be not a 2,8 70-200.

It is the telezomm till 4xxmm.

What we see this year is the new Q and maybe lenses for aps-c and ff.

The converter production got a power up now,because there are still much more orders than production numbers

Cheers."

NOTE: As regards the production of the 645Z on another thread - Production plans DO change in response to market demand. Rumors that FF was temporarily pushed aside by 645Z may have some basis in fact.

Not everything that is here today sprung up overnight.

Canikon built their current lineup piece by piece, year by year, camera model by camera model. Nikon was very slow to move away from APS-C and step into FF, Canon was equally slow about moving away from APS-H and into proper FF. Their current FF lineup was a slow evolution.

I believe there is room in the marketplace for Pentax to introduce a FF, and progressively develop their role in FF. Just like Nikon and Canon have done.
I agree. And FF is quite a 'niche.' This isn't quick AF sports niche or portability niche... but just a general purpose dFF in K mount. That is a huge gaping hole in the product lineup imo.

I want to point something.

Both rumors, about sales of 645z and about the postpone of Pentax FF seems to come from same kind of sources. Dealers. One of this rumors is, in my view, clearly false. Maybe, the second rumor, about the postpone of FF is also false. I don't know. But both rumors seems to serve the same purpose. Pushing up the sales of the existing cameras, 645z and K-3. At least this is my opinion.
It is possible.
Every 2 years rumours go crazy around September and I do warn everyone to take all notions with a handful of salt.

There was never such a rumour Monochrome; it would presume the intimate knowledge of the FF to come, but there is nothing that even remotely confirms the FF. Not even Asahiman. All his rumours about the FF or announcements about 'immediate lend releases' in the last 12+ months or so were not accurate.

"Postponed FF because of 645Z" is just a wild speculation from those who believe Pentax engineers can't think and can't handle two things at a time.

thank you. I will bury this first rumor in a pile of salt then and keep looking out the window...

Can be seen as a joke.
Probably.
But it's real.
It has similar size and almost the same weight as K-3.
We'll have to wait and see then....

Now, talking not about rumors, but about leaks for this Photokina, something is obvious for me. We already have two leaks, (with almost no rumors before) about a lens for 645z and about Pentax Q-S1. But is too far ahead of Photokina. I remember well that rumors about K-3 starts to be consistent about 2 weeks before, and the leak came one week before official announcement. This makes me think that are more to come, and maybe the best will be the last.

So, we have to wait, (and hope).

So.... Asahi man says there will be a "4xxmm telezomm"...... has anyone heard any other rumors about this new telezoom?
