I'm pretty sure it's a pentaprism. However I was a little
disappointed to see it's still only a .9x magnification and 94%
coverage. On an APS-C camera, that still adds up to a relatively
small viewfinder. Especially in light of the D300's 100% view at
.94x magnification.

It is 0.9x with 95% magnification.

The D300 costs over two-fifths more than the Alpha-700!

The nearest competitor to the Alpha-700 is the Canon 40D...
That is 0.95x with 95% magnification.

However; the 40D is 1.6x crop rather than 1.5x crop. That gives you approximately the equivalent of 0.89x, which is smaller than the Alpha-700.
