I can really understand that people are rhapsodizing about "Leica colors" - Modern Leica lenses have even better colors than modern T* for my taste (though of course I would never pay that much for that difference, the pop-song-like T* colors are good enough for me )
I think you can't reproduce them easily with PP
Here's a sample for different color rendition
--->Same place, same time, same light, same camera, same camera settings ("vivid mode" which of course highly increases color differences due higher saturation), very similar PP (sharpening, some minor tweakings etc.)<---
Rodenstock Rodagon 105mm F5.6
_DSC4979
Carl Zeiss Sonnar 55/1.8 T*
Carl Zeiss Sonnar 55 1.8
Check out colors of the fur or the grass ^^
The Rodagon is good sample for rather bad colors (I love that lens anyway, but only for macro/closeup work or technical/reproduction stuff)
Both lenses are very sharp, high contrast, virtually no CAs, no glow,... basically both are optically flawless, but for my eyes they highly differ in their color rendition and the modern T* gives much more beautiful colors than the Rodagon which was unlike the Zeiss never optimized for colors. Despite oversaturation the T* looks imho much more natural and pleasing
[b]Feel free to try to reproduce colors of the modern T* coating by post processing
I can not do that, not even close to that! (Though of course I know many people are very much better than me in PP but I think even for them it wouldn't be easy)
I think colors of a lens are at least as important as it's bokeh and it sharpness etc., unnatural colors can make a good picture look bad for me.
Luckily not many lenses have seriously bad or weird colors but there can be huge differences. _________________ I'm not a collector, I'm a tester

The aperture will stay at the smallest setting(F22) if the lens is not powered. _________________ https://lensfever.com/

Taping is not possible like calvin said (or F22 only).
Distortion and maybe vignetting are corrected by the camera automatically when shooting in JPEG (but not when shooting in RAW), but camera does nothing with the colors it doesn't also do to the Rodagon.
As said camera was set to "Vivid"-mode, which gives that slightly oversaturated colorful look, but that's applied on both pics
When shooting RAW and increasing saturation in Lightroom the difference it similar. _________________ I'm not a collector, I'm a tester

To enjoy the characters of the lens, I will not correct the colors but pay attention to the WB. It is important for us to understand the characters of the lenses so that we can pick the right lens at the right time for the right scene. _________________ https://lensfever.com/

Minolta used to have an advertising theme of "Minolta colors". I very much like my Rokkor lenses. I think Topcor captures colors well, especially blue. I have a Jupiter-9 with yellowed glass that takes very warm pictures, but that probably isn't what is being asked. Aside from those, the only other in my collection that comes to mind is Komura, and in particular, the 3.5/200. _________________ Regards,

Even in film days when these claims originated, processing and printing were rarely consistent enough for the claims to be taken seriously. Nearly everybody now applies a tweak to colour, contrast or whatever which makes claims about the unique colour rendering of some particular lens to be even more redundant.
I now take these claims to be nostalgic whimsy........nothing wrong with that mind you. |

I think you are quite right. Back in the old days having pictures printed required a good service for best results, but colors were balanced. Of course, slides offered a more consistent and accurate representation. Today I see a dramatic different between exposures; wide open shots are consistently warmer than those where the metering and color balance is done through a stopped down lens. However, I do see what I perceive to be a noticeable difference in certain colors with certain lenses. I've thought that Topcor gave especially brilliant blues. I have found also that some lenses do a better job of not blowing out the whites. _________________ Regards,

And if you do enhance color with software, the more you have to start with, the better you will do
If you have alot of lenses and really shoot them you will probably notice how different they really are, but since light is such a huge factor, you really need many shots in varied conditions to understand a lens colorwise. I shoot the CV 35/1.2 quite a bit. It has a very particular palette. Generally I like it fine, but you can play all you want, it won't look like a ZM 35/2. Of course you can change both of those lenses. But they always look different. Play as you might.
MS Optical Sonnetar is another lens with it's own ideas about color.

Some get the idea that because you can alter something, that means you can change it into whatever you want. The are few things more attractive to humans than the fantasy of control _________________ Making MFlenses safe for the letter *L* |

It's just that in the film days such tweaks were a domain of professionals, and now everyone can do it, and do it well, if he/she is willing to spend the time. |

In fact, all the three photos were taken with the Zeiss. To be more exact, the three pictures are JPEG conversions of the SAME RAW file! The first picture is the result of converting RAW -> JPEG by Adobe CameraRaw, the second by a generic online converter and the third by DCRAW. The three converters used their default settings and the pictures suffered no post-processing except downsizing.
Clearly, only the first image is visually acceptable; the other two are simply awful. It seems that ACR made a "smart" conversion, probably using the metadata embedded in the RAW file, such as color temperature, gains of the RGB channels, lens profile, etc. In contrast the other two converters seem to have made "dumb" conversions.
Visually, the three images are totally different, but the JPEG images are equivalent in principle, in the sense that it would be possible to transform an image into another by post-processing. To prove this point, I took the Photo # 3 and by manipulating by trial-and-error the curves, levels, contrast, intensity and saturation in Photoshop, I tried to get the same rendering of the Photo # 1. I came to Photo # 3 corrected, which is quite close to Photo # 1.

The lesson I draw here is that speaking of unique color rendering of a lens is somewhat misleading. Perhaps this discussion made more sense in the era of film. In the digital age, the data generated by the sensor suffer so many processing that it is perfectly possible an average quality lens produces photos with color as good or better than very expensive lenses. After all, a good lens, as well as a perfectly clean glass window, should produces no color by itself. _________________ If raindrops were perfect lenses, the rainbow did not exist. |

As above. Colour is not too hard to adjust with the right software, a good sensor helps but not as much as a good lens design ,glass and coatings. You don't need to pay the earth to take an acceptably good shot, you just need 'the eye' and the digital darkroom skills. Only those who were present during the taking of any of these shots would know how much difference there was between the natural light and that which appeared on the screen post session. For instance the takumar shot of horse and rider, that could have been late afternoon one summer, shades of the golden hour in there. This is all just my thoughts, not facts.
I think if you up the ante on your PP skills colours are whatever you want them to be. _________________ A whole bunch of stuff. |

Bingo.
As someone else said earlier - Yes, it is possible to infinitely manipulate the colour of your images now in PP, but that doesn't automatically mean you can achieve the same result as a particular lens. _________________ In my bag: Sony A7II - Olympus OM 21mm f/3.5 - Minolta M-Rokkor 40mm f/2.0 - Konica Hexanon 57mm f/1.2 AR - Olympus Zuiko OM 100mm f/2.8 - Pentax 135mm f/3.5 |
