Wow! That's quite a crowd. I gotta ask what do you need so many for?
I doubt I'll ever move my E800 again and I doubt it weighs as much as those.
Over the next couple years, I'm going to get them up and running, and sell them off.

Olympus AX70/80/MX80

After lifting two MX80’s up a flight of stairs, the AX70’s and even the one AX80 feel so light weight. Amazingly feather light. On another note, yes under pressure I’d be the second one to admit that mistakes were made. There is one more AX80 at a delivery depot waiting and two AX70’s create in stor...

Re: Makeshift vibration isolation?

Anyway, good information and ideas. I definitely need to do more to dampen vibration.

qualitative difference between infinity corrected objectives

So Olympus is 180mm, Mitutoyo is 200mm, and Edmund Optics/ThorLabs has 150mm. Somewhere I'm told that the large that number the more stable the image is for putting a sensor somewhere along there. But I never really understood that.

Re: Axiomat Objectives

What I'm trying to understand is that between two objectives that need to pair with telan lenses 164.5mm and 250mm respectively, there appears to be something in the signal between to the objective shoulder and the telan lens that makes this pairing necessary. So somehow in the angle or image diamet...

Re: Axiomat Objectives

Based on the performance of Axiomat objectives when adapted to an Axioscope, they require a telan lens closing in on a 250mm focal length, maybe a little less. I don't know what the reference length of an Axiovert is : the same as an Axioscope; 164.5mm? So how do you find that out? I was worried ab...

Axiomat Objectives

Will the Zeiss M27 44 ## ## objectives work with the Axiomat tube lens? I don't know what corrections are in the optical path of the Axiovert versus the Axiomat.

And what about the 42###-9### ones?

It looks like Axiomats are 46 ## ## model numbers.

Thanks,

Is this just a 50/50 camera option with one of Olympus's cameras? I would have thought there would be a slider rod. Unfortunately, the white background is too diffuse for me to enhance an image of the opposite side from the background data like there would easily do in NCIS or CSI. :(

I know it sounds daft...but have you tried a coverslip ? Camera set-ups use a sheet of glass, so a microscope slide or, as suggested, a cover slip would project the light and yet give a good image.
