Hi Bob,

It is a Zambuto mirror, but currently un-coated.  That's another side
project I'm trying to weasel my way into (not coating it, but getting the
chance to have a once over of Paul's shop at Spectrum coatings )

Currently the Camera is 'bitchin' about low light, so I'm pretty sure its
maxed out its sensitivity.  However since it doesn't have a manual method
to control sensitivity I'm pretty much still hoping for the best!

Take Care,
James Lerch
