WLF is great when you get older too.
I never thought I would like the waist level finder on a camera, but that changed as I got older. When you get bifocals, and the eyes don't focus on things as fast as they did when you were 20 years old, that big screen puts the fun back in photography. I still use a 35mm but my way of focusing that is to turn the lense one way till it is blurry, turn it back the other way till it is blurry, then put it in between and hope you are close. Another advantage I'm finding is that now stopping down the aperature to see depth of field really works with a wlf. With a 35mm the image is so small in the viewfinder that you can really see the difference anyway. Ric.
