Thanks Philippe,
Details,
These are B&W negatives developed and scanned at my local Fuji lab using
I believe one of their frontier machines.
The + - expo compensation is as you described on the R7 but I never use
it because it is quite awkward to manipulate. Easier to use manual mode
and compensate via shutter speed.
just like me ;-)
Lens is fully closed down but I must admit that at times I have failed
to reset after changing shooting modes, eg, from aperture priority back
to program ... maybe that's the issue.
happened to me too, we could start a club ...
Here are a couple sequential frames shooting the same scene. I'm pretty
sure both were taken in program mode with the lens stopped down to min
aperture ... but I can't be certain.
OK

Not OK

Technically not the same for the cell - one is vertical and right -
probably because it takes the ground as a reference - the sky area is
small in proportion of the ground/grass
the other horizontal - light is measured with a gradation for the upper
part of the frame (usually sky in horizontal mode) yet it takes here a
much larger proportion of the measurement area I guess, hence slightly
too dark , which may have affected the scanner readings too
using the + / - thing or going manual could then solve the pb - but
this is just a guess

ouch!
is this a print or a scanned neg?
two leds is no issue so far as I know - you get an intermediate aperture
value I guess (no exif to prove it though) - watch that you're not out
of the aperture/speed range, that's all.
backlight - I never had an R7 but as early as the R3, you can alter the
exposure setting and tell the cam it is backlit for instance; the + -
switch should be on the left hand side where you adjust the ASA/ISO (and
somewhat tricky to change when your eye is against the window BTW, later
improved in the R8/9) - it is there on the R4, its location shouldn't
have changed as it is the same family
Also, it depends on the cell setting - centered, 'full screen', etc if
availble in PRG mode on the R7 (isn't on the R4).
I suppose we need more details.
Hope this helps for a start though

An after-thought, when shooting in programme mode, is your lense fully
closed down?

Hello,
I am getting some unpleasant exposure results with my R7 and I don't
know if it is my inexperience or something to do with the camera. I use
P mode often and maybe it's just not suitable where there is strong back
light.
The other possibility is that the leds on the right are displaying two
aperture modes when I take the shot, eg, f2.8 and f4.0 lit up. The
manual instructs to change the shutter speed dial until only one
aperture reading displays, I have largely ignored this. Anyway I get
two or three shots like this in a role and the only pattern I can see is
the scene has bright lighting in the background.
Here is an example. Maybe someone has experienced this, I'm hoping it
is operator error.
