Could you use an enlarging lens? Or are they too slow? David ------------o------------

Larry,
Unfortunately, I do not think that there are any modern projection that can effectively cover 6x9 cm. transparencies. Pressing camera lenses into projection service might not be the best choice because of heat etc. The best MF projectors use lamp sources that are 500 or 750 watts. That means a lotta heat!
My experience ends at 6x6 cm. Possibly Eric or Richard, who are in the entertainment world, can suggest something.

SoRichard,
The old lantern slide projectors that used ~3x4 slides had lenses that were totally inadequate compared to the fantastic lenses used on the better Rollei und Leica projectors. And the H'blad projection lenses are just as good or better than the Leitz or Rollei 6x6 projection lenses.

Any suggestions' for a good bright modern replacement lens for my magic lantern
used for say 2x3 slides?

At this stage, I reckon digital projectors are absolutely fine for their primary purpose - business presentations. They don't hold a candle to a projected 35mm slide, never mind a 6x6 one.

In my experience business slide shows are usually so badly done that the method really doesn't matter. The sharpest projected images I've ever seen were from an old fashioned lantern slide projector using 3-1/4 by 4-1/4 plates (or whatever the size for the old B&L prjectors was). 6x6 comes pretty close. There is to my eye the same difference with slides that one gets on prints: going from 35mm to any larger size negative is quite noticable.
