Leica CL Full Spectrum conversion for IR.

Recommended Posts

Advertisement (gone after registration)

You Tube VideoHello everyone!

I am back with another mod. 

This time I converted my Leica CL into a full spectrum camera to use it for infrared photography.

Here is a time-lapse video. I will soon post some photos from the camera.

Hope you like it.

Cool.  I had one of my CL's converted last year by LifePixel, not to full spectrum (although they do offer that) but to what they call "Super Color" (equivalent to 590nm Filter).  It, at the time, was the first CL they ever converted.  I will be curious as to your post processing.  Lightroom has its limits (in regards to color balance) and many use Capture One.

I went a bit crazy with my new skin, but I figured why not.  LOL

 

I was disappointed to discover that the TL 35 F 1.4 was NOT an ideal IR lens, but many of my other (TL and M) lenses are.

i use DNG profile editor to create a profile for each IR camera, and then apply that in LR

Thanks.  I have done the same, post applying the profile I then edit the file in Silver Effects Pro.  I am still not convinced I am doing it as well as I could.  Do you convert the file to monochrome in Lightroom post applying the profile?

 

Thanks

once i import into LR, the raw pinkish colored file turns monochrome once i apply the profile >

THANKS.  As my filter is 590nm, I do not go to fully B&W post the profile.  I can get there, it just takes a bit more work.  The advantage, is that I can capture close to normal, not a huge increase in exposure time.  

 

Still learning.

Sounds cool.

 

I come from a large format B&W IR film background, but most of those skills do not translate to the digital world.  I love IR photography, so getting into the digital aspect of it.

This is an example using the Sigma 45mm F2.8.  That is a very good IR lens.

 

IR Hot Spot Testing

SORRY, I was wrong about the Sigma 45mm f2.8 for IR use.  I did a bit (allbeit basic) testing of my (SuperColor) converted CL and this is what I got.

 

I plan to test my R glass tomorrow.

I ended up getting an M8, not fussing with the conversion, have to filter the lens but I get acceptable exposure times. I did my first experiments with my unconverted CL, exposures were too long, required a tripod, the 23 did really well, but my 25 Canon (Leica thread was awful on the CL). But on the M8 it works really well. Using a 720 filter:

Great.  Although each conversion (based on the filter used) will be diffrent, it is nice to get a feel for which lenses are the best.

nice :) please post some more photos at 720nm or 850nm

 

 

Thank you for embedding the video. I couldn't make it work.

The TL lenses I tried are:

18-56mm = pretty good, no white spot;

11-23mm = pretty good, no white spot;

23mm = good until f8 if remember correctly.

To develop the raw I use Capture One and I usually set the white balance with a grey card in camera.

It helps me get the best exposure (ETTR).

If you are interest I can also post the RAW files of the fore posted pics.

I just ordered the Leica apo-macro-elmarit-tl 60mm f/2.8 asph, will be here tomorrow.  Hope it works well for IR, we will see (soon).

      After lots of discussion about future of APS-C. How many of you think that the real reason for CL/TL being held back is the lack of native lenses ? 
       
      A little history :
      - 2014 : T was released with two lenses : 18-56mm f/3.5-5.6 & 23mm f/2.0
      - 2015 : Then two more with 11-23mm f/3.5-4.5 & 55-135mm f/3.5-4.5
      - 2016 : Leica release the only two made in Germany TL lenses : 35mm f/1.4 & macro 60mm f/2.8
      - 2017 : CL was released with 18mm f/2.8 pancake lens  
      Leica were on a good track, 1 or 2 TL lenses per year. But after 2017 ? Nothing happened at all ! 
      We should have 10 to 14 lenses by now. Not 7. 
       
      Only 1 fast lens. Only a trinity of slow zoom lenses. Only 2 compact prime lenses.
      None of them have OIS. None of the bodies have IBIS. 
      No portrait lens, aka equivalent to fast 85/90mm or 70-200mm f/2.8. 
      No fast wide angle. ex : equivalent to fast 18/21mm. 
      These lens cannot be replaced with any adapted M and R lenses. 
       
      So what’s the problem here ? Leica may think that APS-C line do not sell well enough. So they stop releasing new lenses  ? It is a kind a vicious cercle. But  no new lens = death of the system. 
      Just like they left the S line died by releasing only bare minimum body upgrade and no new lenses for half a decade. 
       
      So what do you think about this situation ?

      My [almost] two year old Tekiac Stealthcover’s tripod mounts popped out - yes, both of them. And the plastic started cracking around the tripod mounts, to boot.
      Thinking it’s time to update it anyway I went to LFI (where I first got it from) but lo and behold, it’s not there anymore.
      A quick visit to the Tekiac website and wouldn’t ya know it, it’s no longer in production.
      Does anyone have a suggestion for an alternative? Really only need it to do the three things the Stealthcover did well:
      Have a grip Cover the logo Have a tripod mount Bonus points if it comes in black 🤟
      Thanks!

      Recently bought CL as I used leicas many years ago as a prof photographer - now retired.
      Is it possible to program  CL to only use "M" setting or to remain on the "M" setting when manually put on ?
      (I want to control my exposure myself and not be dictated to by the camera.)
      What "off camera" flash should I buy for the CL. Thinking of second hand Metz or new Nissin but which hot shoe to use ???
      Thanks

      Hi, I've just bought my cl. Can someone explain how top right wheel is used for magnifying the evf image. Thanks

      Playing around yesterday, I discovered this weird flare pattern when pointing at the sun. Images are at f/8 and f/5.6.
      Is this ... normal? I’ve never seen anything like it.
      Setup was:
      Leica CL M-Adapter-L Voigtlander 40mm f/1.2 Voigtlander 75mm f/1.5 No filters on any lens, either, so not sure what could be causing it.
