question (in Engish, sorry..) (but an answer in german is no problem..)
I want to use an olympus P7X oculair for photomicrography, with my Olympus E trinocular microscope and a Sony nex3.
I've seen there are olympus P7X and olympus Bi P7X oculars, "Bi" meaning binocular (and "P" standing for Plan, but that does not matter here).
The Bi's seem to have a lower collar.
(see also http://www.alanwood.net/downloads/olympus-micro-optics.pdf)
Now I'm using an Olympus P10X, which gives me a too "narrow" image on my camera. A magnification of only 7X will help this at least a bit.
My questions:
- what's the difference between the two oculars Bi P7x and P7X ?
- and, most important: can I use a Bi P7X for microphotography instead of a P7X ?
Thanks

Hi ddb!
I think, "P" doesn´t stand for plan but for photo....
I don´t have any experiences with this ocular-like versions. In former times I used the NFK2.5x in combination with the Sony nex and had best results.
Kind regards

Hi BBD
I know the P7 very well, it is a Olympus "Projektiv" designed for taking pictures on 135mm film. The P7 is able to build the picture alone, no additional optic between P7 and Sensor needed. If you use the P7X you need a additional pancake (lens) to bring the picture to the sensor - it is constructed for observation ...

Hi,
"Bi" stands for "binocular". These were sold as "matched pairs" of eyepieces.
At the time, many microscopes were still monocular, so you could buy individual eyepieces. For binocular microscopes, you were able to buy pairs ("Bi") which were matched for use on the same microscope, matched presumably (??) by magnification.
There are equally suitable for photography.

Jon
