APO 50 Summicron and coding

When I check the LCD back of my camera it says uncoded when I use my APO Summicron 50. I do find this a bit strange as the 246 recognizes the Elmarit 28 ASPH without problems. Do I have to manually set a code (?). When I edit my photos in Capture One it does recognize the lens as the correct one. Does the lack of coding affect the file before it's passed on to the editing program?

Could be several things:

 

Lens not in correct position

Dirty or damaged code sensor

Very very early firmware

 

It does seem odd that C1 recognizes the lens as it gets the information comes from the 6-bit code. There is no Manuel entry for this lens as there is no uncoded version so maybe you've selected an earlier version of this lens in the manual menu?

 

Something seems odd, mine works in auto mode. Hmmm interesting. Works in exif, but not reflected on back of camera. Odd indeed

 

 

Could the frame select lever be stuck? What are the frames when the 50 APo is on?

[Mr Fjeld]

Thanks for the reply. I took it off and on again and now everything looks alright. Strange?

Having said that, it has happened before. Will this possibly affect the image quality in any way?

[Soden]

It might affect image quality, but given the nature of this lens. Probably not much as it's a highly corrected lens.

 

I have found that some lenses are a little snug on some bodies. It might correct its self over usage. Better to check by pressing the info button from time to time.

Thanks for taking the time to help me Soden   It could very well be tight tolerances. I'll keep checking that info button!

I've had this happen various times over the years and it was because the lens wasn't fully mounted.  When mounting the lens onto the camera, listen for the "click" of the pin that keeps the lens from rotating off the camera body.  Sometimes I'll think of the lens fully mounted, but there is still just tiny bit more rotation needed to get it to fully click in place.  Hopefully this is the case for your situation.

Thanks for your reply - and I think you are right! It hasn't occurred lately, but then I've made sure to be more "firm" when attaching the lens.
