(except that you don't want to continuously switch focusing screens)?
That would be a fairly obvious reason. I shoot a variety of subjects using both AF and manual focus lenses and the improved AF system was one of the big draws in favor of the K-3 over the much less expensive K-5IIs. Loss of spot metering with an aftermarket screen is truly no big deal, but loss of a major camera function is quite another.

Have you tried the K-3 stock screen? The viewfinder is much brighter than the K-5.

I may be wrong, but doesn't the K-3 ship with the same MF-60 focus screen that came with Pentax dSLRs since the K-7? Viewfinder brightness is not the issue. Rather, it is apparent depth-of-field (equivalent to about f/4 at best) that makes manual focus with the stock screen a joke.

K3 viewfinder is slightly large than K5 with 100% coverage and 0.95 magnification (0.92 - k5) , but is not really a big difference.

Yes, but the focus screen is the same size as always (the size of the sensor for 100% coverage...funny thing). Magnification is a function of the eyepiece ocular.

Have you tried it? I just checked with my A50 f1.4. I focused on a number of things, in low to medium light close in, and then checked with the liveview focus peaking, and it was right on. I could see the depth of field. I know I couldn't with the K5, I installed the ees screen to get decent manual focus.

A split or ees screen makes it very obvious, but the K-3 viewfinder works.

But greater magnification should help, right? I know people using K-5's with O-ME53 magnifiers specifically for manual focusing. Although 0.92 vs 0.95 seems like a small difference to me.

A friend who has k5II says that using manual focus is better than the k5...
