First, if you’re tethering, make sure there’s a tethering solution that works for you with this camera.
Secondly, make sure your Post Processing solution is to your liking. In particular, Capture One won’t support Pentax MF cameras - whether tethered or not - because Phase One views them as competition to their own (somewhat superior but more expensive) MF camera systems. Most other PP software will probably be fine. This is unfortunate
, since IMO Capture One is the best.
As you know, like most Digital MF sensors it's cropped compared to film. But once you’ve verified the necessary infrastructure (as above) is in place you should probably find a good lens or two and try it!
