The Pentax is highly regarded for a number of reasons. The exposure dial is very useful, but for me the main attraction is the simplicity of the meter. There are no unnecessary settings, modes, buttons, features, etc, that burden a lot of other photo equipment. Just a nice accurate spot circle, a trigger, and an clear EV reading. That's it. Perfect for the job I want it to do.
For that most others will do the same. That is an EV readout in the viewfinder. As far as accuracy most others are not any less accurate.
