tappan Posted May 7, 2013 Share #1 Posted May 7, 2013 Advertisement (gone after registration) They look like the aperture blades. Any idea what it is? Thanks, Mark Welcome, dear visitor!

Jay B Posted May 7, 2013 Share #2 Posted May 7, 2013 Grossly overexposed, and light is leaking around the edges of the aperture blades. Not a nice thing to do to your lens or camera... Link to post Share on other sites More sharing options...

Alan Philpotts Posted May 7, 2013 Share #4 Posted May 7, 2013 Hi Mark Given that you have shot directly into the sun, it looks as if it is caused by light reflected from the (shiny) sensor during the exposure. I think this has illuminated the the back of the iris, so the bright edges of the blades show up in your picture. Both sensor and iris are flat surfaces that act like mirrors. I sometimes get this sort of thing from small light sources at night. Secondary images appear when light is reflected from the sensor to the rear surface a filter and back.

jaapv Posted May 7, 2013 Share #5 Posted May 7, 2013 It is clearly a reflection off the aperture blades. They must be a bit worn on the edges. Link to post Share on other sites More sharing options...
Ecar Posted May 7, 2013 Share #6 Posted May 7, 2013 It is clearly a reflection off the aperture blades. They must be a bit worn on the edges. Or perhaps slightly greasy, which would increase the effect of reflection under strong light. Link to post Share on other sites More sharing options...
tappan Posted May 7, 2013 Author Share #7 Posted May 7, 2013 Advertisement (gone after registration) It is clearly a reflection off the aperture blades. They must be a bit worn on the edges. The 35mm FLE did not behave this way. Is it something to say about the 1955 design of the collapsible or is it something to say that maybe the blades are worn on the 1955 collapsible?

jaapv Posted May 7, 2013 Share #8 Posted May 7, 2013 Worn/reflections. Have a look through the front element of your lens. Link to post Share on other sites More sharing options...
tobey bilek Posted May 11, 2013 Share #9 Posted May 11, 2013 reblacken the blades. The lens will never perform like a new one. I know I don`t work as well as I did 60 years ago. Link to post Share on other sites More sharing options...

Tobey, this problem only happens with an extreme exposure, like the one above. For other photos, this lens is more than adequate except for the known lack of contrast, which I am ok with. Do you suggest that I should fix the blades to add years to this lens? Can one actually fix thie blades, is that possible? Thanks for your answers, hopefully :-) Mark Link to post Share on other sites More sharing options...
