Hi, I don't think the reasons for keeping the film line open are as
simple as you state. It will be a question of demand. This may stabilize
in the future, and we may be surprised at the outcome. Kodak, as all

Kevin the answer to your question is in Harold Edgerton's book
"Electronic Flash, Strobe" MIT Press. ISBN 0-262-55014-8
Flash duration is a complex subject it is measurable and is a function
of capacitance and voltage. Voltage and its duration are easily measured
with an oscilloscope.
T=RC/2
T=t
It would be interesting to compare the M15mm f3.5 lens to the DA14.

I have noticed references to Windex glass cleaner, and it is my
understanding that ammonia which is in Windex is corrosive to lens
coatings, and front surface mirrors.

I have used LX cameras for the last 20 years, and have found they fit my

I sometimes use a Pentax 200 f2.5 with a Pentax 1.4S converter. This
combo works great, and has the versatility of having the option 200mm or
300mm lens.

Ilford's printer paper division is doing really well, in fact is has
been carrying the photo paper, and film division. So I expect the
printer paper division will be around for a while.
