The topic came up in a couple of threads and some of the reading I have done on various photo forums... specifically related to the Fuji X-series cameras. So I thought I would do a test.
I did a number of comparisons in different light as well as interior & exterior... there was no difference in my testing when using the Fujifilm X100T.



Given the specifics, I wish all tests were this conclusive ; )

I was actually expecting there to be a difference
and the Sekonic reading was a bit of a surprise... F 2.0 0/10
was all the chatter about the Fuji X-series (supposedly) exposing different from a hand held meter... and I wanted to confirm or debunk that web-factoid. One would expect consistency, but there are always some variation...
With older (film) cameras the shutter speed is often off (particularly the slow speeds)... and even modern dSLRs have slightly different exposure priorities. Canon is/was known to be slightly hot when auto measuring TTL flash.
But yes, it should be consistent...

With the x100t I use in-camera JPGs so the camera is doing the post processing and it's interesting to see the choices made... The Fuji developers know the strong points of the camera, have some idea of what makes a 'good photo', and might prioritize accordingly...
just looking into the details ; )
