...Olympus who seems to be stuck in a rut of non-innovation.
Wasn't micro 4/3 innovative in a way?
...Olympus who seems to be stuck in a rut of non-innovation.
When faced with that sort of choice, I certainly can't justify $1,100 for the Fuji X-100s ( no matter how cool it looks / good it feels), when that sum almost buys a decent DSLR outfit...
Sorry mate, it pains me to say that while I absolutely love the old Olympus when geniuses like Y. Maitani ruled, I have slowly grow to hate the current Olympus who seems to be stuck in a rut of non-innovation.

Perhaps Fuji will step up and reintroduce this in digital... 😉

Well not exactly 1000 is actually 1/1000th -- there is the rub...
1/1000 is a smaller number than 1 -- but the dial is marked 1000, so a "larger" marking is less light, even though it is actually a smaller number. Explain that in class. 😀
The f-stops are marked with whole numbers and indeed while they are also fractions of the focal length of a lens. no one has as much trouble with them. It is always enjoyable to explain that "1, 1.4, 2, 2.8, 4, 5.6" is half as much light per stop. Good luck with that.
My experience teaching is -- that many master it, but few have even a vague understanding how the math [science] applies to the numbers.
Any discussion of DOF on the RFF soon turns from math [science] to the "religion" of bokeh.
They're both marked with the denominator of fractions, so the ordering is the same—larger number shown is a reduction. Exposure time selector ("shutter speed is so imprecise ...) goes up by factor of two to cut light one half. Aperture f/number is a little trickier, but the relationship of the numbers is that each larger one is squareroot of two times the last ... difference is that it's an area measure, not a linear measure.
Just explain that to the noob who has questions. ;-)

But our hands have evolved over thousands of generations to work well with tools, and none of those tools were designed to actually *fit* our hand.
We made tools to fit our hands not evolved hands that fit tools. Pick up a stone axe sometime. It sends a shiver up my spine to hold a tool made 1,000s of years ago that fits my hand perfectly.
