In Topic: Yet another DIY fibresnoot

I think this is feasible but I'm not convinced the light from the spotting torch would be bright enough. If I were pursuing  this, then I think it would be worth having a trial out of the water by temporarily fixing some fibre optic to the spotting light and trying it out.

In Topic: Lens choices for a MFT system

Hi Wolfgang,
That would be Cozumel for Underwater Digital Fiesta where I teach every April. 2015 will be our fifth year lots of fun and great people.
Charles, The E-M1 is Olympus top of the line pro camera and like the E-1, E-3 and E-5 only replaced about every four years. I would NOT expect to see a new E-M1 release before about Photkina in Nov. 2016.
I use the 60mm macro with +5, +10 and +15 C/U lenses. I also use the wider Panasonic 45mm macro with a +5. Dry C/U lenses (diopters) do not work well beaches the ports are designed to get the lens as close to the flat port glass as possible. The more mm between the lens and the back of the C/U lens the less magnification so it the lens sits back far enough in the port for dry C/U lenses it will to be as effective with wet lenses.
We all or most of us anyway came from DSLR cameras. For me it was a Nikonos RS film camera then Olympus DSLR cameras with the 43 sensor. I feel like the gains far out weight the losses and the M43 format is on par with APS-C cameras as a total system.

Encouraging comments; thanks Phil. MFT seems to tuck the boxes for me, but it seems like a big step. I'm off to have a look at some housings in the flesh, so to speak.

Thanks for these replies. One of the attractions of the MFT system is the availability of a wide range of u/w suitable lenses.

What is the working distance of the 60mm macro? I was wondering about diopters too- is there the possibility of using a dry diopter, or just wet?

I'm still unsure about whether MFT is right for me, and how it will feel coming from dslr.
It also occurs to me that there might be a successor to the em1 before spring...
