<p>Hello Again,</p>
<p>Thank you for all the great responses. I brought the camera to work with me so I can take a look at some of suggestions (just don't tell my boss).</p>
<p>I still need to look closely at the negative - I did once before and it was on the negative however I did not try to rinse or clean it off. I'll also try to determine if they're scratches or in the actual exposure. I'm fairly sure they're in the exposure.</p>
<p>Mary Doo - I have looked at the camera back, it appears very clean, the shutter looks to be in good shape. The camera was purchased from KEH a year or two ago so it has (theoretically) been inspected and cleaned fairly recently. I did notice on the first roller there's some kind of residue towards the lower end of the roller. I'm wondering if maybe the affected pictures are landing on that residue for an extended period of time. Anyway, I'll clean that up and see if it helps.</p>
<p>Matthew Currie - The shutter seems to open vertically and the arms are off to the side and not near the affected area.</p>
<p>Mark L Cooper - The marks happen randomly throughout a roll. Usually on only 2-4 photos. Some rolls not at all. And some photos are worse than others (I've posted a few more at the bottom of this post). I haven't paid much attention to if I was supporting the lens by hand or not but I'm almost certain I was not. The 24mm and 50mm are very light and I usually don't support the 85mm when I'm pressing the shutter release. I thought about the tighter grip idea but this camera is pretty solid, one of the reasons I love it - anyway, I'm not ruling that out. The marks are consistently in the exact same location even with the same line spacing.</p>
<p>CPM van het Kaar - No filters are being used.</p>
<p>One thing your questions have made me realize is that all of these photos were taken outside so the higher shutter speed idea is a possibility. I just can't see anything that would be hitting the film! I've also noticed they seem to be more pronounced on recent rolls than when I first noticed.</p>
<p>Rodeo Joe - The camera was about $250 from KEH. Which, when considering processing fees, I'd happily buy a new one since I already have the lenses. Maybe that's the best way to go if we can't sort it out. Thanks for the compliments on the photo - Cuba is so beautiful it's almost cheating.</p>
<p>E.J. - The streaks do not extend from one frame to the next.</p>
