Dear Steve,
I do really appreciate your input (same as from other forum members) to my question. Actual idea for my writing wasn’t to receive a ready to use solution from forum members since I know that it’s not possible with current hardware / software available.
My point was to rise the question and (hopefully) to draw the attention from the Pentax(Ricoh) engineers regarding the limited Tiff in-camera export abilities.

Point is not about how strong are difference. Point is that there IS difference.
Here is a link to 5 images with clearly visible differences between Tiffs from Camera and DCU
_IMG4762 | Files.fm.
Raw(DNG) (_IMG4762d),
JPEG from camera (_IMG4762j),
Tiff 8bit converted in camera(_IMG4762t_8bit_KP),
Tiff 8bit converted from Raw in DCU (_IMG4762t_8bit_DCU),
Tiff 16bit converted from Raw in DCU (_IMG4762t_16bit_DCU)
When compared Tiffs from Camera and DCU, it’s easy to see the differences between them.
What I want is a technical ability to get an image that I like taken with camera I own with Custom image settings (tools provided by Pentax(Ricoh) tweaked by me to my taste in best lossless format (16bit Tiff) so I can open and edit that image right directly in editing software (Photoshop for example) for a final tweaking (like geometry, sport removal) skipping raw converters.

Take a 128GB or 256GB card and no worries, they are not so expensive now-days… Storage and processing time is not an issue for me.

A already did that. Outcome files are available for download to compare:
Here is a link to 5 images:
5 images | Files.fm.
Raw(DNG) (_IMG4299d),
JPEG from camera (_IMG4299j),
Tiff 8bit converted in camera (_IMG4299t-kp),
Tiff 8bit converted from Raw in DCU (_IMG4299t-8),
Tiff 16bit converted from Raw in DCU (_IMG4299t-16)
If You’ll compare 8bit Tiffs from camera and from DCU – they look different.
I’m not comparing preview image on camera screen and image on computer monitor. I’m saying if I see full size JPEG image on a computer screen produced by camera using in-camera Custom settings and I like it and I want to to do a final tweaking (let’s say geometry, and some spot cleaning) why I can not get it in 16bit Tiff format???????
It’s like to say: we have a superb video camera you can record 4k and even more, we give powerful tools so you can tweak your video right in camera to look it way you like it but save you may it only in compressed mp4 format for internet, no full size. Want it in better quality– take it in pure raw only with no in-camera tweaking saved….

I’m not asking for aDCU’s functionality. I just want to get an image produced to my taste by cameraI own in better quality (Tiff 16bit) then JPEG or Tiff8bit for a final tweakingon a computer? Why I can get it in pure raw format and loosy JPEG or Tiff8bitonly, Why not as a Tiff 16bit?? When there are so many talks an videos abouthow hard engineers work on a new camera to satisfy photographers shootingexperience I see no sense in not offering ability to save already taken imagein a best available quality format…
You’re correct, I may choose Cross processing,Bleached, Muted etc preset and tweak it more to may taste to get an image I preferAND I’m NOT allowed to save it in best available quality format and that’s weird….

Pentax(Ricoh) gives us a really good and powerful tools for in-camera image tweaking via Custom settings users of other camera brands may dream of only with one small catch – we may not save them in editable format. Let me explain – as long as I shoot my images without applying Custom setting and save my images in raw to do image tweaking on a computer later, everything is fine. Problems arise when I want to add Custom settings to the image during shooting and save the results in lossless editable format, for later tweaking on a computer, let’s say in raw. All raw converters will see a pure raw image only without Custom settings applied, whish is normal since Pentax(Ricoh) doesn’t cooperate with large software producers in that field. As far as I know Fuji shooters may import images taken in raw with Fuji film simulations applied in camera in to Lightroom and Lightroom will ‘see’ these simulations and will let further adjustments.
Pentax DCU ‘sees’ Custom settings applied to the image in Browse window only. As soon as image is transferred to Laboratory(editing) window, pure raw is opened without Custom settings applied.
The only way to save images taken with Custom settings applied so far is to convert them to Tiff files in the camera later. Problem is that there is no way to save them as 16bit Tiff – 8bit only. One may say that 16bit file is huge… that’s correct, but for today’s memory card capacities that’s not a problem I guess ;)
Pentax DCU also offers convert raw file with Custom settings applied to the Tiff image from Browse window to 16bit of 8bit Tiff files with one small catch – they look different.
Here is a link to 5 images:

Tiff 8bit converted in camera (_IMG4299t-kp),
Tiff 8bit converted from Raw in DCU (_IMG4299t-8),
Tiff 16bit converted from Raw in DCU (_IMG4299t-16)
If you will compare camera tiffs with DCU tiffs, DCU tiffs are darker at least…

When converting in camera, colour space specified in settings is used - same as for images taken

I’d be glad to work with raw files directly, but there is a small problem - if I save my taken image as raw, computer based raw converters (including Silkypix) doesn’t ‘see’ custom settings added to the image in camera, just a pure raw.
So if I, for example, want to take an image with Monochrome Custom setting added, I have to save it as JPEG (loosy compression format) or in raw and then convert it in camera to Tiff for final tweaking.
Of course I can do conversion with Pentax DCU which‘sees’ my Custom settings applied, BUT the problem is that DCU use different conversion algorithms than in-camera converter with resulting in differently looking image.

Pentax cameras has function to convert raw filesto tiff image (8bit) with Custom image settings applied.
So may wish is to addTIFF format as an output format in File Format in the Image Capture Settingswith ability to choose between 8bit or 16bit.

Need advice regarding Exposure Lock function onK-70. Since on this camera AF button is combined with AE-L button, only onefunction may be selected as active for this button at a time. User manual doesn’tstate any possibility to assign AE-L function to any other button. Customfunction AE-L with AF Locked is not an option. Any workarounds? Thanks inadvance!

When all photos from both cameras are copied to hard drive in to one directory, open that directory in ACDSee browser. Select all photos. Mouse right click, select Rename / press F2. Batch rename window will open. In Template window use/input template ''. In Search and replace tab replace empty space ' ' with '_'. Press Start rename. All images will be renamed to file name pattern YYYY-MM-YY_HH-MM-SS and will stand in chronological order. ;)
RRRRRR. editor replaces ':' and 'D' with smile after 'Image' in template sample !!!!!

I've allready red all available info about 16-50 on this forum and many other places around including Pentax 16-50 /Sigma Tamron 17-50 comparition on this forum.
I know that 16-50 is not an easy lens to shoot with. I do not care about size, weight or even SDM.
My question is - is this lens designed allready 10 years ago still optically up to match high resolution sensors?

Need an advice regarding Pentax lens 16-50. Have used it since it was released on K10D as a main lens for all kinds of shooting. Receantly droped it during a lenschange so now need a replacement.
So, my question is if anybody have used that lens on latest generations of Pentax APS-C cameras like K-70 or KP and how does these lenses perform optically with new high resolution sensors? Is 16-50 a good match for them or better is to wait a while (for something unknown yet to come....)?
I'm interested in16-50 range WR/AW lens with f2.8.

K10D with firmware 1.00, 1.10, 1.20 will work in screwdrive mode with 16-50 right from the box.
K10D with firmware 1.30 will work in SDM mode with 16-50.
