Whats this line on the horse?

Second example (same kitty). In the second image I increased the fill-light to make the line more visible. I browsed through my pictures, and it seems to me that the problem mainly occurs with slow shutter speeds. Maybe it a shadow from one of the shutterblades or a heat issue??

 

That's about the same height as the one that appears in my images.

 

It's definitely not a problem of image transfer to computer, because I can see it on the camera lcd, not do I believe it's a card issue.

I think you're correct that it shows up with slow shutter speeds - but that might just be because typically at high iso a slow shutter speed means a darker scene (whereas a brighter scene might hide the effect).

 

If you have some reference for the issue, I can send a corroborating image to Leica to help with their investigation.

Thanks Mikki for posting the images. I don't think it is the slow shutterspeed, because my pictures were taken with very fast speeds.(outside, 1200 iso with f4 or f 2,8) i guess 1/1000 and faster.

Is it an animal thing, Andy's maybe right.....:eek:

 

Yes David, if i had an reference also i would send Leica some more pictures.

Just out of interest, I was wondering if it might be shutter related. The curtains are diagonal across the leading edges but could a sticking trailing edge horizontal mask the sensor? Theres a distinct hard edge, then a fall off, as though something accelerates back to speed. And you see it at lower exposed regions using high shutter speed.

I've already got three users that are sending samples to Leica. I think that's enough for now, lets wait until they reply. I've got an email that they're on vacation until 28/12, so we'll have to wait a little bit longer still.

Thanks to the people who've sent me PM's!!!

 

@rob_x2004

That's exactly the same as I thought, but I'm not that technical. All I can do is hope that it's easy to fix.

There is something to this Rob.

I also think its shutter related.

But for me its just a hunch.

Thanks for thinking along.

 

Mikki, it will be next year, received the same email.

OK, just read a post that indicated Leica think the banding in high-iso shots may be related to some kind of interference from other concurrent electrical events in the camera (ie shutter recocking).

 

It occurs to me that I may have only seen this line and patch effect since I got discreet shutter release... I wonder if you guys were using discreet mode in the shots you made? Is there any way to check in the exif to see if that mode is engaged?

There is that - but maybe it is not high ISO, but the attendant slow shutter speed?

 

Yep - but people shoot low iso with low shutter speed on tripods fairly often, or even low iso with low shutter speed hand held. I see it at around 1/30s which is not an unusually slow speed. The horse pics were shot at high shutterspeed by accident, with iso 1250, after walking out of a dark barn.

 

I'm going to run back through my shots and see what commonality there is between the images that have this defect (apart from high iso).

All shots were taken with 1/1500 or 1/3000 in manual mode. ( C1 indicates 1/1502 and 1/3003)

I did not notice a correlation between the hight of the 'line' with a particular shutterspeed.

It seems at random.

I don't think i used discret mode, no. And exif does not tell.

 

David, i read the earlier post, thanks for bringing that up.

 

I wait and see.

Thanks Jaap for sharing your thoughts.

I suddenly recall that my battery that morning (half full) was surprisingly fast empty.

Due too the cold weather i suppose. I have no clue if this can be related to the line?

Just another hunch.

Well, my shots were taken indoors, in a warm living room. I don't think it's related to the coldness.

I recall that I've also seen this problem at ISO 640, but not at the lowest ISO settings. I usually use the discreet-mode, and I did so aswell for these shots that show the line.

I really have the feeling it has something to do with the shutter still, but I can't find any correlation in my pictures at least.

This could also be a symptom of a old battery. Just too many of us M8 users use all too old batteries. How old is the battery? If it is more than 2 years; renew it!

Just another thought: would the M8.2 also suffer from this problem as it has a entirely different shutter?

 

The M8.2 has the exact same shutter as the M8, and the M9 and the R8. It is only the springs that differ on the M8.2/M9 shutter from the M8.

Yay, I got my M8 back yesterday. No comment at all about the horizontal line problem. I haven't had the time to shoot with it yet, but I'll keep you informed!!

 

Ok Mikki, thank you for posting this. Strange that leica did not adress this.

Was a dealer involved?

 

I feel like phoning them.

 

I hope you enjoy your camera?

Best wishes for the New Year.
