CSC compact system camera with viewfinder

*Lucky*

Can any camera or photography techies please recommend a CSC that has a viewfinder in addition to the rear digital screen? I need this due to my eyesight.:o

My other requirements are a decent spec and it must be as compact and lightweight as possible. I want to take wildlife shots but I can't carry lots of heavy kit. My budget is around £400 and I can add to that in the future with lenses, etc. I don't mind buying secondhand.

I have shortlisted:

Panasonic Lumix GF6
Fuji E1 and E2
Sony NEX-c3 and NEX-5
Also, Olympus or Pentax if they have a viewfinder.

I have looked at Amateur Photographer and What Camera online but it is hard to find out.

Have you considered the Olympus OM-D E-M10 Mark II ? Just scrapes into your budget and goes nicely with the Zuiko 40-150mm . 8 fps repeat , touchscreen focus and shooting with timelapse .
