    Weird lines showing up on film when using FD 28mm?

    Has anyone seen something like this before?


    Canon_T90_008 by Abram Goglanian, on Flickr
    (please excuse the terrible scan, I just wanted to show the example)

    I ran a test roll through my T90 and on a couple shots that were for sure with the 28mm (not all of them mind you) I noticed these lines. I've never seen anything like this before and I'm just curious what the cause could be.

    Any thoughts?

    Wow - certainly looks like an optical effect given the circular symmetry, but they're dark...

    Any thoughts as to what it could be and why it wouldn't show up on every frame I used that lens for?

    You weren't shooting through a fence, were you?

    It looks to me as if there is some obstruction in front of the lens.

    Did you have a filter on the lens? A lens hood?

    Nope I was walking across the street. There's no filter OR lens hood on this particular lens.

    Did you scan the negative or first print it?
    Enlarger condenser problem or maybe the scanner's light diffuser out of whack?

    This is actually on the film. I had it done at a shop but I did the scan myself on a flatbed. It showed up on the 4x6 test prints I got from the shop as well. It's faintly visible on a couple frames, but it's almost not noticeable. That's why I thought it was so strange that it was so heavily pronounced on this one frame (which thankfully isn't an important picture haha)

    Could it have something to do with the processing they did?

    I have a T90 and an FD 28mm lens, but have never seen any results like this, have you got the lens recently ? have you tried another lens ?

    You don't remember seeing anything like that in the viewfinder? Not even a faint memory of some light/shadows in the eyepiece?

    Try looking through the viewfinder, hit the stop-down button (whatever it's called, the DOF preview button) and see if you can spot it. Try all the different focal ranges and aperatures.

    I would think something like that would be obvious at one point or another.

    Yeah that's the weird thing. I never saw the rings in the camera. However this was the first test roll using all this gear so if it was a pre-existing problem I don't know.

    I just checked every single lens I have on my T90 looking straight into a light source at all apertures and there is nothing visible in the viewfinder, not even a hint or a trace of these rings.
