not really. D40 was with sigma 50-150 2.8 but even with kit lens D40's viewfinder looks brighter. Mine has some texture which resembles fingerprint.
You might check out a recent post to the Pentax SLR forum on dpreview, containing an excerpt from an interview with one of the engineers at Pentax. As he explains it, there is more or less an inverse relationship between brightness of the focusing screen and actual accuracy in manual focus, particularly with respect to gauging DOF accurately. But I guess there's a tradeoff - obviously, it needs to be bright enough to see well. I guess the microlens lens design can either be tweaked to slightly improve brightness or accuracy of MF, but you can't have it both ways. The D40 apparently chooses brightness at the expense of accuracy of MF; Pentax apparently prefers it the other way around. As someone who uses MF lenses a lot, I definitely appreciate this.
