    Thanks for these interesting articles. Just an observation: you write in your conclusion: "But how can this be? F2 is F2 is F2, right? Well no, calculating aperture (in camera lenses) is way beyond my school boy maths grade however in a hideous over simplification I’ll describe the physical aperture size as a ratio of other factors about the lens."

    It's even simpler than "physical aperture size (is) a ratio of other factors " : there's really just one factor. One shouldn't write "F2": it's a common mistake that doesn't mean a thing (when written down, that is... I admit it's easier to pronounce that way). It's either f1:2.0 or f/2.0 simply meaning: the diameter of the aperture is f(ocal lenght) divided by 2.0. In the present case of a 23mm lens, f/2.0 means the aperture has a diameter of 23/2.0= 11.5mm. An aperture of f/16 produces a diameter of 1.4375 mm if f=23mm. Diameter is of course theoretical because the hole is almost never fully round (in "modern" cameras), the actual shape depending on the number and shape of the blades.

    Sorry to hear of your loss, that's a very good 'portrait' of him. I wish I had such a good one of mine!

    It takes a while, but then I found you can remember positively, objectively and affectionately.

    Circumstances have given me a lot more X-Pro1 than X-Pro2 time lately.

    But away from the spec sheets and out in the real world, just what are the key differences?
