An assortment of F-series Nikons (F to F6, excluding the F4) with quite a few Nikkors, a pair of M6s with some Leitz glass, a pair of 500c/ms with a wide range of Zeiss optics and, just to help keep Duracell solvent, a D800.
I can't tell you much, sorry. They all look similar to me on my uncalibrated HP screen. When projected trough a HQ projector (that's what slides are for) I never liked the look of Veliva or Velvia 100. Fujichrome 100 professional, now long gone, was great, so was the Ektachrome line of films.
