New vs Old > M9 sensor lines increase after Leica USA repair


Recommended Posts

I think, the only issue here is looking at images with wrong exposure.

I hope, OP wouldn't mind if I'll add another one

Fresh battery and same SD card ?

The M9 supply regulation always seemed on the edge.

Even Apple admitted to throttling phones with older batteries that could not hold output voltage at current peaks.

In fact it was a brand new SD card bought the same day I picked up the camera from the Leica store.  I have so many test shots by now that we can safely rule out battery status as well.

I was just hoping that someone else would have checked her/his sensor and compared with the old sensor images.

When you underexpose a CCD sensor you may get banding; that is normal.The amount of banding depends on the amount of underexposure.  These shots are taken at different times, thus under different light so they tell us exactly nothing.

The only difference between the old and the new type of sensor is the cover glass, so it is highly unlikely that there is any change in noise behaviour between the two.

so which one of the two would you think is MORE normal ?

New does not necessarily mean better or equivalent:

I stick to older, slower, small capacity SD cards as the seemed to be less likely to produce.banding than the latest ultra fast cards.

shooting multiple Leica M8 since 2006 I went through all kinds of SD episodes (so yes when it matters and I do not want to deal with lost images I resort to 2GB SD cards )

which exact make do you use ? ( please attach image of card )

From personal experience I can say that it does no harm

taking a few test shots before sending your camera in.

 

Color Checker

Auto Exposure

Bracket 0.-1,-3

ISO160

Tungsten Light

AWB

 

I have seen my camera for a total of 3 days since having it sent to NJ through the Leica Store in June 2017

in fact the camera is still in NJ as we speak ...

 .... and I have a feeling that this is still not the end of it.

 

Go Figure !

I have not noticed any radical difference in underexposed areas between the two generations of sensors. I have been using the same SD card. 

My personal experience is that increased banding in M9 images has always been an issue with the SD card rather than the camera.

Further, here is an image shot with the M9's new-gen sensor. 

 

underexposed at ISO 640, and pushed to around an equivalent ISO of 12800.

 

The banding is not nearly as obvious as what I've seen the old-gen sensor produced at a mere 2-stop push when paired with a 32GB 94mb/sec SD card or a 1st-gen Toshiba WIFI SD card.

      Selling my Leica M9, new sensor in 10/2015, CCD ID16 with a confirmation by the Leica Service that this camera (ID) has a new sensor which cannot corrode. Comes with all assessories and original packaging, receipt by the Leica store where it has been purchased. Fully functional, no issues.

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! Hello fellow Leica users,
      Long story short, I've been a film Leica M shooter for a while now (M2), and I've been considering buying my first digital M. Since they are not even close as repairable as fully mechanical analog M's, I really don't want to spend that much money on a digital one. 
      So I came across a lady willing to sell me her M9 for a "bargain" (something like U$250), but as you guys can tell from the picture above, it comes with the dreaded corroded sensor. 
      I'm no professional and I want one of these to try them out, since I've never truly used one.
      My question is: how's the situation of this one in particular, can it be used in anyway in this condition? Is it worth it for the price? And finally, is the 1000U$ dollars repair worth in my situation? 

      I'll be very happy with any contributions.
      Best Regards,
      Roger
