At ADAPS we tried running competitions that included real 35mm slides and also digital files projected, and the digital ones were brighter, clearer, more vibrant in every way.
Why? Probably because of the resolution and perception of the eye which sees a 72ppi image at several feet away as full of detail. As a print, viewed close, it would look awful.
It will be interesting to see what you think.

No, I don't see any point to using a separate meter unless there is some specific purpose and the requirements are ultra critical.
I've moved this to a more appropriate section.

This sort of thing is one of the reasons for my "Pentax only" argument.

12 months ago I would have said TIFF, but things are moving along and I'd try JPEG as well and see what you think.

I must admit I dont think the lens performs very well in low light
Many lenses perform better with high contrast subjects, such as you are likely to find when the light is bright.
