Well, I dream of not having much to ' recover' at all ... Less processed tonally adjusted files equals better photographs for me!! Will my dream be realised (funds permitting of course ) ??
It'll be night & day Nigel. Moving up from the K7 to k5/30/50 generation will get you 1-1.5 stops extra, then moving to FF will get you another one (sensor area double =1stop extra if it is fully realised).I was rather looking forward to a bit more dynamic range ....

Of course it's (almost) night & day just moving up to the K30 generation anyway

For "methodology" read METHOD. I thought the green rings on the lens barrel was being replaced with red ones. On the 2 lenses just released they are back to green.

ICM is short for 'intentional camera movement', there's no special software involved. The camera is deliberately moved during exposure to create an abstract or impressionistic effect (as in the style of Impressionist painters).I must be missing something, to me they are all out of focus, therefore a load of rubbish.

#10 does almost work for me though.

Are you interested in a couple of long fixed lenses I might find around if I look hard enough?

Unfortunately there is not a zoom lens on the market by any company that can come close to the quality of any fixed lens. In terms of PK; the lens which come the closest are the Sigma 24-70 f2.8, but at the "price of" both size and weight,
Unfortunately even a preset 400mm or also a preset mirrored 400mm will exceed any zoom lens
You are joking? You just don't own a rotten enough old fixed length lens. Believe me there are plenty of stinkers that aren't up to it.Unfortunately there is not a zoom lens on the market by any company that can come close to the quality of any fixed lens.

My main concern about the crop issue is really about having a smaller image, and vignetting and black space within the viewfinder (I assume the live view can just zoom in with a software adjustment?) .... This I would find distracting I'm sure and it would interfere with quick and efficient framing, and focussing possibly. We're so used to seeing 100% of the image in the viewfinder, I feel it would be disconcerting otherwise. But I guess Pentax engineers will find a practical solution.
I actually rather miss the old 'bright line' viewfinders we used to have in rangefinder cameras. Having extra edges visible was really useful - it kept a bit of perspective available for judging whether zooming out|changing lenses|stepping back was a good idea.My main concern about the crop issue is really about having a smaller image, and vignetting and black space within the viewfinder (I assume the live view can just zoom in with a software adjustment?) ....

You're having us on aren't you Greg? 'A mode' is just an abbreviation for automatic exposure modes like Aperture or Shutter priority.Jonathan-Mac wrote:
If Pentax don't un-cripple the K-mount for this camera it will be a crime. Imagine being able to use all the old M and K series primes as you would on an old film camera - either metered manual or A modes. People who want a digital Leica but can't afford one would flock to it.
That sounds amazing!! I didn't even know about those modes .... A mode ... Is that like on the flashes where you set the aperture and ISO manually? I guess on a camera body, if it knows the aperture and ISO it will calculate the time value? Does it still take a reading with a half press? (But that pre -supposes it knows the full open aperture) .... So many questions!If Pentax don't un-cripple the K-mount for this camera it will be a crime.

Truth to tell 'uncrippling' the lens mount isn't going to give us that much. It will give the old M and K mount lenses some of the functionality of the old A series lenses and that's all. I don't think it will happen though - Pentax do want to sell new lenses and we should be grateful for the compatability we already have. Mind you, I have a few old lenses myself so *if* the aperture coupler came back it would be welcome, five years ago it would have been a deal breaker - but now I have a few modern lenses as well so for me it isn't any longer.

If it is indeed lens saturation and not something completely different it should be present in every shot. Simply taking the same image with two comparable lenses and posting the examples should be sufficient to illustrate the problem I would have thought?

There is much talk of 'styles' in, let me call it photographic imagery, where a patrticular photographers extreme processing style is admired and often more important than the specific image content. Then processing steps to reproduce the style are published or even automated in photoshop scripts etc. and then 'followers' of the style can reproduce it at a click of a button. So we have the situation where dramtic images are produced puerely automatically (not that I have anything against that if it is what you want to do) and the original image is (hopefully) the photographers but the end product essentially isn't.
That's an extreme example *but* it isn't that different in principle from where we use any of the fancy tools in our favourite programs for image editing and processing.

It's quite beautiful. But it doesn't bear much resemblance to a photograph

Have a look in particular at Robert Hutton's videos linked out from the darktable resources page link
As secondary recommendations there is the quirky but powerful Fotoxx which does have a video demo link or Raw Therapee at link also has a bunch of tutorials as well. Then mining 'Meet the Gimp' will find endless treasure on everything to do with photo processing.
