Thanks Rick. I found where I can have the lens cleaned. I was told the 55 macro was designed in a way that allowed oil to leak worse then most lens. I'm also having the FA cleaned and new light seals installed.
Now I have some SB-16 flashes that don't work. Do you think they would be worth the expense to have them fixed? I'm not positive what is wrong with them but believe only lose connections.
Later ... H ... :)

Glenn , thanks for your input, you are probably quite right, after I posted the question I spoke to my eldest son who has a physics degree, and has studied nuclear physics when he was at university, he researched it for me on the internet for me because I don't understand much of the information about radiation, he told me that in fact you got much more dosage of radiation watching TV, and anyway at my age drinking too much coffee( as I do) was a much bigger risk.

Mugshot,

You should disregard much of what has been written on the web, about the health hazards of Thorium based optical glasses. A large percentage of sites seem to repeat verbatim, the information from a couple of rather dubious sources. ( A major fault of the internet - people rarely if ever quote their source, thus a great deal of misinformation is passed off as true fact.)

Depending on the geology of the area you live in; you could be at greater risk from Radon Gas in your house foundations, than from carrying your lens about on a daily basis.

The EF is an excellent camera, I think it's the best of the classic Canons this side of the F1. As for health hazards, the exposure of being in a factory making them 40 hours a week is very different from that of having one in your camera bag on occasion. It's a bit like pharmaceuticals: you want to be careful about the dosage you take, but imagine the care that the production line workers have to take making the stuff.

Thanks for replying Rick, I doubt if I will be carrying anything for the next forty years at my age. I recently bought A near mint Canon EF with fitted with the lens to add to my Canon FD system, and subsequently read that the Japanese Government stopped Canon from manufacturing them because of the health hazard to their staff, but what I don't know is was it because of the danger of ingesting the glass dust during the grinding process, or because the completed lenses emitted dangerous levels of radiation,(although I would have thought if so it would fog the film ) or a mixture of both, it looks like I didn't just buy a camera but a research project, in the meantime I'll just have to live dangerously.

Hi Mug:

I'm going to stick my neck out and tell you that the lens is safe to use... just don't spend the next 40 years walking around with it in your pocket. The brief amount of time that you spend with your eye close to the lens in normal use should not pose much of a risk.

If the yellow cast is pronounced enough to be a problem, people have reported success in clearing yellowed lenses by placing them on the windowsill in the sun for a week or so. Wrap the barrel in aluminum foil to reduce the heating effect of the sun, and orient it so that the sun shines as directly as possible into the lens. Being a Canon lens, I guess it will have the diaphragm nearly closed when it's off the camera, so make sure the yellowed element is facing the light.

I recently bought a canon FD 35mm f2 B/L chrome nose lens, the one with radioactive Thorium glass, and the yellow cast, do you think they are actually safe to use, or should I be wearing lead lined boxer shorts.
