I was cleaning some lenses yesterday and noticed that they are getting larger, not growing you understand, they are the size they were when manufactured but being made bigger. I have been thinking of switching to a mirrorless system for sometime but I would still keep the Canon for macro as the MP-E 65mm is a gem of a lens. I keep looking at the little Fujis.
This is what I mean.
Both the first and last lenses cover a standard 35mm frame which is 24mm x 36mm or 864mm2 . The middle one covers a 6 x 4.5 frame or 56mm x 42mm which is 2352mm2. The Zenzanon lens also includes a Sieko leaf shutter which is not an inconsiderable bit of machinery.
Does anyone know the code for squared or cubed (2) (3)?
That’s all for today.
