Hi, I bought a really quite nice M5 last year. I sent it in for CLA not long afterwards and mentioned that there were scratches on some frames (in the direction of film travel). I think they were reduced bait by the CLA, but I know that I could sometimes still see them on some frames when the camera first came back. In the attached photo you can see the scratches on both the left and right side. This one is particularly bad in that the both go almost all the way across the frame. Before I loaded this roll of film I wiped down the backing plate and film guides as best I could. What else can be done to fix this super annoying issue. This is the only thing wrong with this camera, pretty much a joy to shoot in every other way.

Steve - you are assuming a vertical picture cannot be cropped to a horizontal? ;)

Never "ASSUME" - "It makes an ASS out of U and ME!"

As to the original question, it'll be useful to know if the scratches are on the film base (plastic backing) or emulsion side (duller shine). Look at the film from both sides under glancing light to see if you can figure out which.

Another key question would be - developed yourself? Or via a commercial lab? Film can get scratched along its length at several points in the photographic process (even when sliding it into protective sleeves, or going through the felt light-trap of the film cassette). Doesn't have to be caused by the camera.

Andy is correct, this is a crop of a vertical image to zoom in on the scratches.

Unfortunately I guess my eyes aren't good enough to be able to see the scratches on the film. If I had to say I think that they are on the base side of the film. It is very hard for me to tell, but maybe I can see faint scratches in the direction of travel.

We develop our film at home and it seems rather unlikely to be film cassettes since I can see similar scratches on Portra, HP5 or TMax 3200 as in this case. Also they seem to happen wether I load the film or one of my kids does. The reels are also less than a year old from Paterson, so they don't seem like a possible culprit to me. We use PrintFile sleeves to hold the negs also this doesn't seem likely since the scratches I'm referring to happen along the same tracks on the film, never in the middle just on the edges.

I think it's reasonable to ASSUME the OP will describe the problem without ambiguity. The first thing to discover is if he knows his arse from his elbow.

If you process your own film are there any other times it could get dragged against or through something, like do you squeegee if before hanging to dry, or could it be dragged through a scanner or an enlarger film carrier? If the M5 is causing the scratches they will most likely be on the the film base side. Send a roll of Portra out for processing and see if there are still scratches on it in the same places. To test the camera the simple test would be to use another camera and see if you still get scratches. Buy something from a thrift shop or a small compact camera from eBay.

my assumption was as well that it is horizontal frame when I sam the picture. There is different density on the left side, goes vertically and if this would be horizontal picture it indicates shutter problem.

But if the frame is vertical it could be light leak, possibly back door seal. Do you see it on other, horizontal frames?
