Q Sensor Issue?

Recommended Posts

Advertisement (gone after registration)

Hey folks - I just purchased a secondhand Q on eBay. It arrived today and I've been really enjoying the feel after shooting with a 240 over the last many years.

But when I started seeing the images in Lightroom my heart sank.

Can you take a look at this and tell me what I'm seeing here? Looks like the sensor is corrupted somehow?

Thank you!

 Some of those spots are not birds. If other shots show the same, return the camera

my first Thought --Basejumpers or ParaTroops

 

anyway it looks weird

  Best thing to do: take some shots of an evenly lit surface at different ISO settings, different apertures, focused and defocused. What do you find then?

Those are all very uniform in their general shape I believe they are parachutes

 

Agreed.   Expand the image and I can see some chords.  It’s very easy to clarify whether there’s a fault on the sensor.  Just take one more image and check for similar artefacts.

however, the darker artefacts on the left may indicate a different problem.  If they are still present on a new image, then yes, return the camera.

i think they might be Leica parachutes being tested for remote delivery of Q2 to remote dealerships

please let us know the outcome. . 😊

Be interesting to see the whole picture 

Why?

I would attempt to take a clear blue sky photo at f/8 then take that image and the camera and return immediately to where you purchased it. I do not ever remember seeing any artifacts like you're showing previously with a Q. Dust spots yes, but not "parachutes". The Q should not have any artifacts like you're seeing. Good luck. Please inform us on the forum of any discoveries as to what is going on if you learn anything. Otherwise, find another Q.

To detect dust or spots on the sensor you do best to use the Leica M 240 advise. Smallest lens opening (Q2 f:16 defocus 30cm) take picture of evenly lit grey subject. Most convenient is to use an Expodisc in front of the lens.

      I purchased a Q end of last year, liked it so much that I sold my Nikon DSLR, Lumix FZ-2500 and Fuji XE-T3. I then purchased the CL with the 18-56mm lens a few months later. Now with adapters to use my Rokinon wide-angles, and 7 Artisan lenses I find myself using the Leica CL way more than the Q.  There's no doubt that the IQ of photos from the Q, a full-frame camera, are better than the Leica CL, t's a fantastic camera and lens with macro capability.. But I'm thinking of selling it add more lenses for the CL (or at least pay it off 😎).   Anyone else face this situation?    BTW, with all that's going on in the world at this time, I'm fully aware that this is no big deal, but it keeps my mind off the other cataclysmic issues  we're experiencing.  All opinions welcome, any recommendation for lenses?...thanks.  I am currently waiting for arrival of the TTArtisan 35mm F1.4 lens to ship.  Be Well everyone.

      I took a very underexposed shot and tried raising the exposure 3.4 stops, and I expect noise, but what are these horizontal lines? Is it normal? This was taken with my 'new' used LeicaQ. Is this expected? I've never seen this before, and I've definitely shot underexposed before. Should I return this camera? Is it defective? Thank you!

      RESERVIERT Verkaufe gebrauchte Edel-Kompaktkamera Leica Q (Typ 116). Die Kamera hat kaum Gebrauchsspuren. Das Display und das Objektiv sind frei von Kratzern. Sie diente mir als Zweitkamera, kam aber selten zum Einsatz, da ich doch lieber mit meiner SL fotografiere. Zwei original Leica-Akkus sind dabei, sowie ein neuer Tragegurt, ein Ladegerät, die Geli mit dem Metalldeckel der minimale Gebrauchsspuren aufweist. Dies ist ein Privatverkauf- I send only within EU.

      Is it possible to set up the Leica Q to be used as a webcam for Zoom and other video conferencing meetings? If so, any suggestions on setting it up?

      With the important caveat that this post is largely speculation, let's anticipate the performance characteristics of the M10-R sensor.
      The Leica S3 sensor is 45x30 mm (1350 sq mm) and the DNG files are 9816 x 6512, for a total pixel count of 63,921,792 pixels, or 47,349 pixels per sq mm
      The Leica M10 Monochrom sensor is 36 x 24 mm (864 sq mm) and the DNG files are 7864 x 5200 = 40,892,800 pixels, or 47,330 pixels per sq mm.
      The pixel density of the two sensors is so similar that I assume the discrepancy comes from non-scaling edge usage factors, and/or small 0.01 mm-scale rounding errors in sensor size.
      So if we assume that the S3 sensor and the M10 Monochrom sensor come from the same process, differing only in size and the presence of the Bayer color filter array in the former, then it's reasonable to assume the M10-R sensor also comes from the same process, and is basically a 36 x 24 mm crop of the S3 sensor (as others have hypothesized in this forum previously).  
      If this reasoning is correct, then you can expect the M10-R sensor to be the same as the M10M sensor, plus a Bayer CFA, and to perform more or less the same as the S3 sensor on a per-square-mm basis.  Therefore, I would expect:
      - DNG files that are 7864 x 5200 = 40,892,800 pixels
      - Dual gain design
      - 4.6 µm pixel pitch
      - Base ISO = 100
      - ISO range = 100-50,000 (basically one stop lower than the 160-100,000 ISO range of the M10 Monochrom, as one might predict from the lack of the Bayer CFA in the M10M)
      - 14 bits per pixel
      Good ISO 12,500 photos and decent ISO 25,000 photos would be terrific, and a significant improvement over the M10/M10-P, as noted here:
