>>3332176I use a WLF. It's by far my most preferred viewfinder. It takes a little bit to get used to, but you will get used to it.
The WLF is ridiculously expensive to buy alone ($150+). Try to buy a body that comes with one. Prisms are cheap to buy by themselves if you decide you want one.
I'm not much of a portrait shooter, but the 80mm is quite nice for that as is the 150mm.
