Radioactive lenses on FS100?
Anyone know if the radioactive rear element of the 50mm f1.4 Super Multi Coated Takumar will in anyway harm the sensor on the FS100?

Re: Radioactive lenses on FS100?
Explain yourself Dennis. Radio active? Do Asahi owners have to wear lead-lined protective suits to go out shooting? And is the half-life 1000 years?

Re: Radioactive lenses on FS100?
I wish someone had told me years ago my takumar 50f1.4 was radioactive... I've been shooting for years and never realized it...

Re: Radioactive lenses on FS100?
There are a few clips on youtube related to radiation and camera sensors. I vaguely recall a link to one of these from dvinfo a few weeks back. A researcher has annihilated some camera sensors with radiation. For some forms of radiation, the normal glass IR filter conferred protection. She had to remove this to achieve pixel kills from radioactive sources.
This link should put you in the ballpark for closer searches :- http://www.youtube.com/watch?v=w7MDBzRo3nM Whilst normal usage may be minimal risk to a sensor it would be prudent to store the lens away from the camera. Last edited by Bob Hart; November 14th, 2011 at 09:44 AM. Reason: added url |

Re: Radioactive lenses on FS100?
Wow, I had no idea - is that all the SMC Takumars or just the 50 f1.4? Is it dangerous to have say 6 of these in your camera bag all the time?

Re: Radioactive lenses on FS100?
I do know that many photographers that used these vintage lenses have since died. To be safe you should give your lenses to me.

Re: Radioactive lenses on FS100?
I've had my fill and taken the necessary precautions against further offspring. Thankfully I apparently have a backup plan as well now.
