      Quick and dirty corner performance test using S1R and SL2.
      SL2 on Left S1R on Right. Lens is 28mm Cron ASPH V1 @f2 minimum focus distance. Pretty nice bump in corner IQ from SL2.

      I have a trip planned for January 2020 to the Azores and Lisbon. I plan on bringing my M240 with 35 Cron, and 28 Ultron VM. I want to do some landscape and seascape images and would like to get a wide or ultra wide angle lens. I'm looking for suggestions or user experience on what is available. Right now my top choices are the Voigtlander 12mm f5.6 (which i can use on my Xpro2 as well) or Voigtlander 15mm f4.5 which will be cheaper but won't be useful on my crop sensor (I already have that focal length covered). 
      My other option would be the Leica 21mm f3.4 SEM... which I hear is an excellent lens but would require me to sell some gear fast to afford it. 
      Anyone have any other suggestions or can give me insight on their experience with the choices i have listed?

      I’m new to photography, I’m trying to decide between the M10P and the Monochrom M246. I’ve read all the forums about the pros and cons of each choice. I shoit primarily in b&w but I like at least having the option of shooting color. With the M10P, I’ve heard about “Monochrom Mode” when shooting in this mode will the images show up as a black & white preview on the LCD Screen?
      is it really that big of a difference/ time consuming effort to convert each and every M10P color photo to blk & white? As opposed to little PP Time with the Monochrom M246?
       Thanks,
      Robert

      Hi everybody,
      I’m a computer science engineer who has been working, as a hobby, the last three years in a new, more precise, way of recreating film look with digital cameras.
      I’m posting here for feedback, in case anybody of you would like to test the application (with the M9) and show the results and your opinions.
      I usually shoot film photography but also I like the comfort of digital. The problem is that I’ve never been happy with existing film emulations. Mainly because of that, because they are emulations instead of simulations.

      METHOD USED
      For doing so, instead of doing a generic conversion for every camera, I’ve done a specialised conversion for the Leica M9 based on simulating the chemical process and spectrum response, instead of applying curves and other stuff.
      In the end, I thought, if analog and digital are just two instruments which capture light, I thought, maybe is there any mathematical conversion to make the digital to look like film?
      I mean, if I take the same photo with analog and digital, under exact same conditions (light / aperture / exposition /…) could I make them look exactly the same?
      It’s based on chemical simulation and the Leica M9’s response to spectrum. Then LUTs and finally some extra calibration. I think that it could be improved because I’ve used home made or open source tools for calibrating and so on, which are far from perfect.
      EXAMPLES (Analog vs Converted Digital)
      Following are some examples of Superia 200 and TriX 400.
      Click in each photo to see high resolution.
      DNGs shoots taken with Leica M9 (left), and FILM shoots taken with Minolta CLE (right) at same conditions (aperture / exposition / ISO).
      All shoots taken with Zeiss Biogon T* ZM 35mm f/2.
      The examples show several photos, which are the following:
      +------------------------+------------------------+
      |      original DNG      |                        |
      +------------------------+------------------------+
      |      converted DNG     |     scanned FILM       |
      +------------------------+------------------------+
      |      developed DNG     |     developed FILM     |
      +------------------------+------------------------+
      For the generated simulated negative TIFF file and the scanned TIFF file I’ve applied exactly the same develop parameters.
      TriX 400 - 1
      TriX 400 - 2
      TriX 400 - 3
      Superia 200 - 1
      Superia 200 - 2
      Superia 200 - 3
      Superia 200 - 4
      Superia 200 - 5
      Superia 200 - 6

      CONCLUSIONS
      Tonal range - Biggest difference between digital and film
      Dynamic range - Digital is faaar more detailed in the blacks, film never gets burnt, meanwhile digital gets burn quite fast.
      Film has more microcontrast, it's more sharpen
      Digital is a little bit more contrast after developing, I imagine it’s because it reach white level faster, then, when doing autolevels with the developing program, as a result, it’s a more contrast image.

      DOWNLOAD
      I'm having a console application ready, if interest is shown it will be ready quite soon!
      CAVEHEATS / LIMITATIONS
      The program only accept DNG, because I need all the light captured by the camera, instead of a JPG already converted and really dependent on camera self made adjustments.
      The program only accepts photos taken at the ISO of the certain film that is gonna be used. For example, for TriX400 it will accept only Leica M9 DNGs at 400 ISO. I’ve also done tests with ISO 200 and 800, and the results were quite satisfactory but, for complexity reasons, I prefer to let it be native film ISO for the moment.
      Highlights are not always correct, and sometimes they look weird, mainly in color film. This is due to bayer sensor pattern and its different intensity response (for Red, Green and Blue channels).
      FUTURE (& PAST) WORK
      Leica M10-D
      Leica M8.2

      THANKS
      Super thanks to the creator of LibRaw, a wonderful C++ library for working with RAW files.
      Any questions I’m open to answer 🙂
      Best regards everybody.

      Hi,
      I have had a M6 (serial number is in the 1665000 range) for about 7 years now and to be honest, haven't used it a lot in the last few years, but fired it up again recently and noticed that I think the light meter is functioning odd. In the past, I could press the shutter button when the film wasn't wound on and the light meter would activate, briefly, and then I could set the exposure. Now it doesn't do that, but when I wind film on, it will activate the light meter and not turn off until a photo is taken.
      I ran a roll of film through and it works fine - i.e the exposures were fine - it just seems to activate differently that it used to. Is this a common thing anyone knows about?
      I live in Melbourne, Australia and it's tough to get a repairer here who will look at an M6.  Any advice would be REALLY helpful. 
      Thanks in advance!
      Scott
      (Also, I added a photo of my camera just 'cause it's a nice looking thing.)
