That makes no sense at all. There is a great amount of incorrect knowledge
and misunderstanding spread far and wide on the net. If I see one more
person speaking about a lens "shading" I'm gonna scream. I read once that
the average american has a vocabualry of less than 250 words. How can one
function that way?

Well, not exactly plenty, but it is a 25mm so it's better than something
like a Noctilux.
Now I have a question. There has been some discussion here in the past.
I'm of the understanding that a f0.95 lens is a true f0.95 regardless of
sensor size - after all, if I put a medium format f2.8 lens on a 35mm body,
it's still f2.8 AFAIK.
But there is a persistent theory that a 0.95 on an FT sensor is really
equivalent to a true f1.7 or some such. I really don't understand the
thinking behind this claim.
Anyone care to opine on this and help me make sense of it before I make some
claims in print.?
