CV 25/4 M9 ==> underexposed

I will today use RAW. Then I will use LR to convert the files after some basic processing.
 
I have no exposure problems with the CV 25mm on my M8, but then it crops it a bit, and I tend to shoot raw for more exposure flexibility in post (LR4). But I see no difference in exposures between the cv skopar and my leica elmarit and summicron lenses. I do miss the rangefinder coupling on the cv though, so I only use it if even 28mm isn't wide enough.
 
Yes, the CV 25/4 works fine on the M8. I've had no issues with it, but on the M9 it is a different story.
 
I will give it a try first.
1. I have changed in the M8 and the M9 the setting for the files from JPG Fine to DNG.
2. I will set the cameras to the lens detector setting that seems closest to what I am using.
3. I will use LR to downlaod the images.
4. If all fails, I have the M3 and M6 and the Hexar RF and many other film cameras to enjoy.
 
I just took my first shot ever in DNG!
This is a historical moment in the life of my M9.
I set the lens detection to 28/2.8 for the Kobalux 28/3.5.
There is no vignetting that I can see in this one shot. :)
 
You'll do fine Raid. It does take some learning. Don't give up! I would set your camera to shoot a jpeg and a RAW.
 
When comparing the output of my cv 21/4 with my zeiss 35/2 I find the CV needs much more post processing, especially needing way more brightening of exposure and shadows. From my experience it just seems to expose differently.
This on my M8.
 
Just looking at the back screen of the M9 I can see better results with tne Kobalux 28mm lens when setting lens detection to 28mm lens and using DNG.
 
Raid - congratulations on your step up to RAW.

Now it's time for the next lesson. :) When I use my CV lenses I set the M9 to "manual lens selection" for the nearest-equivalent Leica lens, because my lenses are not coded. For the CV 21/4 I set it to the 21/2.8 setting. (I then save this as a pre-set, but that's in a later lesson.:) )

When I import the DNG file into Lightroom, I still have to apply the lens corrections based on the lens profile. In the Develop module, on the right side of the screen, there's a tab for "Lens Corrections". Under that tab there's a tick box to be turned on, then there are four other boxes with selections. You can play with the selections, and turn the tick box on and off to see the effect of the correction on the image.

Below the "Lens Corrections" tab there also a tab for "Effects", where you can control the correction for vignetting, or use it to apply vignetting where that is desirable.

Even with the lens profile selected in the camera, I find I need to make these corrections manually in Lightroom to get the photo to look the way I like.

Good luck - I hope these new tools allow you to have even more fun with your collection of wonderful lenses.
 
I will try out your tips, Chris, and I will inform you I am going with it all. Thanks for your encouragements. I do not give up easily. I am still planning on taking the M9 and the SWC with me on my next trip.

On wide-angle lenses there is a much larger risk of the highlights/sky in the image fooling the internal exposure meter into underexposure. You must really be aware of the metering pattern of your camera and which part of the image you are exposing for.
 
Jaap,
This is all new to me. I got the M8/M9 quickly, and now I need to learn. RFF members are great in helping out patiently with advices.
