Help with pin pointing a problem

I just finished taking a new roll today. When I had them developed I found a very strange problem. I can't tell if it was an exposure issue, my camera, user error, or a developer error. Any help would be greatly appreciated.



Most all the pictures have a white cone such as this one, just in varying degrees. I've never had this problem before. Also, I got a new lens and 2x teleconverter. Not sure if that would make a difference. Either way, I just want to figure it out so I can adjust accordingly.

light leak in the camera or the processing machine (if a lab developed them)

If you did not see this in the viewfinder through your new lens and extender, double check the camera back to see if anything is stuck in the light trap.

You should shoot a test roll and send it to a different processing lab if you didn't process the film yourself.

Thank you guys for the feedback. I'm really hoping that this isn't a camera issue. I called the lab that I had develop the film, by the way I described it, she said that it could of been a bad roll of film. Currently working on my test roll right now.

I would like to see some of the other shots, but to judge from this one alone, I would say it's a light leak at the film plane. As said, if it was a leak at the connection between the body of the camera and the Tele/lens, you could probably see it in the view finder. I am assuming this to be 35mm. At the top of the white cone there is a hard cut off line, this would be there because something is putting that area in shadow from the light. Does this camera happen to have a removable prism? The block of light would suggest that the light is coming from inside the body, but not necessarily from the lens area. The light could be coming from bad foam around the prism? Just my thoughts but take a look.

Also take a look at the progress of the cone shape. Is it wider at one end and then gradually get narrower to the other end? that could be a leak as it was spooled on either reel or core. If it is here and there throughout the roll, it could be the amount of light getting to it is being restricted in some way via aperture stop down or fingers in front of hole.

Does the problem affect the film outside of the frames (the frame numbers, film type lettering, spacing between frames)?
If not, then suspect a shutter problems.

What camera is this from?

Also, time of the exposure and how were you shooting that day?

Well the posted pic is shot almost directly at the sun, which is hiding behind the contrail in the sky.Almost looks like a reflection(flare) off the bottom of the mirror box. It wouldn't show in the viewfinder as the most of it could below the edge of the mirror. The missing flare at the top of the pic is most likely a shadow of part of the baffling in the bottom of the mirror box.

Edit, Lots of snow to reflect the light around too. Hmmmmm,, fog on something, but doesn't look like it.
