By the way, have ever compared the 25/2 to the FA* 24/2? I have the latter lens.

In my opinion, photos shot a "new" Ektachrome 100 could have looked better in terms of color. I hope the images will shine with a better scanning.

A few days ago I replaced the focusing screen of my Z-1p on the screen from MZ-M. Their dimensions are absolutely the same. Then I compared the spare screen with my other spare screen from the K-1. The K-1's focusing screen is visibly larger.

KX-Digital, I guess your assumption onl focusing screens, relating the K-1, is wrong.
What I found in various posts on different forums is the following:

Pentax K-1: 38,25x26 mm
Canon Ee-S: 38,5x26,3
Leica R4-R7: 37x24
Pentax LX: 35,2x25 (36х25)
Pentax MZ-M: 35x24,5
Nikon F6: 38x27
Minolta X-700: 37x25
Zenit 19: 37х25

I don't say 24-70/2.8G is the bokeh king. What I stressed on is that the Sigma's bokeh is too dull. Actually, not only the bokeh was dull but images as a whole. It's hard to describe but they look something like this - :fedup:
:) The D FA* 50 may be a little bit better than the Sigma 50 Art but there are similarities between them. Images don't look natural, they look vapid.

As for the 85/1.4G, yes, its bokeh was smoother but also in a way like the Sigma. images from FA*85 look much much better. Some say that one of the reasons for this is because there are too many lens elements in them. Too much glass is not good for micro-contrast, 3D-pop, and rich color.

I'm not talking about any sorts of weird types of bokeh. I just want to say that if a lens is super sharp and it it has very smooth bokeh it doesn't necessarily mean it is a great lens. A few years ago I had a Nikon D750 plus a few highly regarded lenses (Nikon 24-70/2.8G, 85/1.4G, Sigma 50 Art, Tamron 70-200/2.8 G1). At first, I was so impressed by the Sigma! I almost didn't shoot with other lenses at all. A perfect autofocus along with an extraordinary amount of details... I was glued to that combo. However, after a few months, I began to notice that I like the images from my 24-70/2.8G much more. They were much more pleasant to look at! It was not the versatility of zoom lens that I liked more but the images as a whole! Now I am vaccinated against such lenses and I can see their look from distance :)
I'm almost sure that any owner of the D FA* will love their Limiteds much more after a while ))

The D FA* 50/1.4 bokeh resembles me the bokeh of Sigma 50 Art. It is so soft that it looks almost unpleasant.

I exported my photos edited in Lightroom as jpegs and now I almost never use Lightroom anymore. Lightroom, no doubt, is easier to use but photos edited in Silkypix have much better colors. So usually, I edit photos in Silkypix and if I need some more minor adjustments, I export a .tiff file from Silkypix and then edit it in Photoshop.

This was also my first thought about the issue. However, in Silkypix this "wheel" is absent (actually, as well as in PDCU. in PDCU one can only see changes on the "wheel" but can't alter them by dragging the corresponding points).

Reproducing Pentax jpeg colours with spectrophotometer

Yes, this logo was a sign that a product was thoroughly tested and it was up to the corresponding standards.
By the way, a few months ago I bought a Jupiter 37A 135/3.5. What a lens it is! This kind of lens could be one of the Limiteds. It is very small and lightweight, built like a tank, it is ridiculously sharp right to the very corners and has very pronounced 3D-look and clarity. It fits well in my camera bag along with the camera and 3 other Limiteds. Before when I needed a long focal range, I grabbed my FA*80-200, but it is so huge and heavy that I have to pull out all other lenses from my bag :) To me, the only bad side of the 37A is its default colors. They are somewhat bluish. But they can be corrected quite easily. Afterwards, they just pop out!


Surely, I also make small adjustments. Usually, my photos really begin to look better but as for the 100% jpeg reproduction, this method isn't too good.



Yes, I found this! Thank you for your help! I did quite many adjustments and saved a new .dcp profile. My images began to look much closer to the original jpegs. The colors now are visibly better than from the ordinary ACR's "Camera Bright" profile. However, OOC jpegs still look better.
I then gave another try to the Silkypix. I don't know how its "engine works" but the Silkypix produces absolutely different look than any other converter that I tried (except for the PDCU). Images tend to look "natural" like in OOC jpegs or PDCU (here I'm not talking about 100% colour reproduction). After spending some time with the program, I guess, I was able to reproduce jpeg colours quite nicely. At least, now images with my "jpeg colours preset" look not worse but a bit better than OOC jpegs! Of course, by saying that I mean only the default look after opening a file and applying the preset without further corrections. However, I think that the default look is very important even for future heavy post-processing.

Thank you, guys! I think my question is closed for the moment :)

You're welcome!
I've just downloaded the Adobe DNG Profile Editor. I opened my .dng image of various colour patches. Then I tried to apply the "Camera Bright" .dcp profile from the ACR so that I could make little adjustments. Unfortunately, the Adobe DNG Profile Editor doesn't read this .dcp file. It wants a recipe (.dcpr file). I renamed ".dcp" to ".dcpr" but it didn't help. I guess, now it's time to read more about the Lumariver :)

Well, you're right. Generally speaking, there are more than just one sharpening method in the Lightroom. However, if we're talking just about the global sharpening in the Develop module, there is only one method. Using this method, one can move 4 sliders: Amount, Radius, Detail, Masking. On the contrary, in the Silkypix there are 4 such methods:
1. Unsharp mask (Amount, Radius, Threshold sliders) - practically, the same method as in the Lightroom, but without the Detail slider.
2. Normal sharp (Outline emphasis, Detail emphasis, False outline contr. sliders) - somewhat ordinary sharpening.
3. Pure detail (Outline emphasis, Detail emphasis, False outline contr. sliders) - for the extraordinary amount of small details.
4. Natural sharp (Outline emphasis, Ringing artifact contr., Bokeh preservation sliders) - this is a new method that appeared in the 8th version of Silkypix.

The fourth new method is just phenomenal! The sharpening is really done in a very natural way and images look very-very sharp and with almost no visible noise (even at default settings)! The Lightroom sharpening looks very mushy in comparison.
Also, in the Silkypix there is another global sharpening method which is called "Demosaicing sharpening". It can be used in conjunction with all other methods but it is something different. I don't use it at all. Nevertheless, you can see how more advanced the Silkypix is regarding the sharpening issue.

Ofcourse, Silkypix supports presets. Unfortunately, I haven't created a preset that would systematically be equal or better than the OOC jpegs yet.
As for the sharpening, I disagree that it doesn't matter too much. Silkypix has not one but four types of sharpening algorythms. Lightroom has only one of them.

I'll try to know more about the Lumariver, thank you!

Thank you, guys!
BigMackCam, you've got a cool Avatar! :) I tried to adjust the sliders in the Camera Calibration section in Lightroom. It does help but still, the adjustments are too rough to my taste.

TonyW, I guess, your advice on trying the Adobe DNG Profile Editor really can help. I looked through the .pdf file you linked and noticed that the adjustments can be done very precisely. I should give it a try. If it works, I'll have to stick to the Lightroom or Photoshop with its ACR. Although I don't like them very much, it'll be OK.
As for the Silkypix, I would really like to use it more. Sometimes it seems that only minor adjustments should be applied and the colours will be 100% equal. Alas, it looks like there aren't corresponding all the sliders so that I could make the correct adjustments. At the same time, there is a very interesting instrument - "Contrast center" (along with the ordinary "Contrast"). I suppose that Pentax also uses such an instrument in its OOC jpegs but all other converters, except for the Silkypix, lack it. Also, the sharpness in the Silkypix is phenomenal!

I like the default colour profile of my Pentax K-1 ("Bright"). Such colours one also can get in PDCU. However, everyone knows that PDCU is not the most advanced converter in the world. If it was only possible to get the same colors in Lightroom or C1 or Silkypix, it would be just great! Lightroom has a very close color profile that is called "Camera Bright" but it is still worse in comparison to OOC jpegs (in my opinion).
So I thought to myself that maybe there is a solution to the problem. Maybe somehow it's possible to use a spectrophotometer that I have (ColorMunki Photo). At first, I should meter the colors from an OOC image, then I should meter the colors from the raw image in Lightroom/C1/etc. Then I must upload the data to a somewhat software so that it could create me a color profile for my converter. All it's left is to find out the software that has such a functionality.
Could anyone help me in my search?

P.S. I should stress that I don't need "correct" colours, I need the exact colours that can be found in OOC jpegs.

Does anyone know what Silkypix settings equal to "Bright" profile of Pentax K-1? I know that Silkypix is a different converter but it seems to me that the "Bright" profile can be reproduced in Silkypix because PDCU is powered by Silkypix.

Yes, and there is definitely a "3D-pop" in this image. By the way, in what software did you convert this image? The colours look beautiful.
As for the 50/2 Makro, I think of it not as a macro lens but more as a general purpose lens. In this regard, it is much more useful than the 100/2 Makro.
