Chris,
This set is likely made by a company making tubes for many styles and models
cameras. The instructions are "generically" correct. Just doesn't need to
be calculated with OM cameras. BUT, these are the exposure factors.

Hi, gang! It's "Mr. Confused" again! (Grin!)
I also bought a set of no-name manual extension tubes for my Olympus
outfit. The tubes came with a very brief instruction sheet that says I need
to compensate for the aperature when using the tubes. So, for instance,
with the 50mm lens and the 15mm extension tube, the instruction sheet
says I need to multiply the aperature by a factor of 1.65 so that f4
becomes something around f6.6 or so.
Huh?!?!?!?
I thought that the Olympus measures the exposure off the film plane at the
time the shutter triggers??? If so, do I *really* need to worry about all
this exposure compensation stuff, or will my faithful Oly stuff figure it
all
out for me???
I hope Oly will do the job for me because my math is really rusty and I
don't wanna have to carry my laptop with me to calculate exposure
settings when I use the tubes! (Grin!)
Again, thanks for any help you can offer!
Regards,
Chris
