mercer mentioned a Takumar being radioactive. I think that's something everyone who gets into buying vintage lenses should be aware of- that some are radioactive and they should make an informed decision about buying them with that knowledge in hand. I fully understand many, perhaps most, of you are not at all concerned about the radioactivity of some of these lenses. But it might be something the OP wants to keep in mind.

@Flynn We are on the same page Flynn , I couldn't understand why the others where giving me a hard time about my focal length selection while your post showed they are the most popular.
 
But BTT please. I don't know why this again developed to a sensor size discussion. I really think people like to talk about it, even if everybody understood it already.

I'm not sure what you're saying here. Do you believe Super 35 is similar to what is commonly referred to as Full Frame- like a 5D? The sensor in a Super 35 camera like the Arri Alexa, at least as I understand it, is almost identical to APS-C in terms of field of view. I simply mentioned those focal lengths because I figured you and other folks would find it interesting, the focal lengths that other DPs tend to find most useful.
