Summary: I use this VF-2 with my olympus EPL-1 and I love it. It slides right into the hot shoot. Nothing holds it in but I have not had any problems with it. It has stayed in place. Very easy to use, helps alot in sunlight. Some might think its bulky, but I personally like how it looks on my camera.
Summary: The VF-2 really helps me compose better pictures when lighting is low or bright. It also allows me to hold cam in more traditional manner without extending camera to see through LCD. A must have for a micro camera.
Pros: Durable, Easy To Use, Lightweight, Quickly attaches to cam
Summary: I am getting to know my new Olympus e-pl 1, and so far, it has been a pleasure, except for using the LCD screen in bright light conditions. The vf-2 allows for tight, reliable focusing. What impresses me is that it retores the feel of the Olympus OM line. Unfortunately, the viewer is a little bulky and when mounted, makes the camera too big to fit in some cases.
Summary: A bit bulky/pricey to use for everyday photography, the viewfinder is essential for zoom photography as it allows for more stable shooting and for fine focus control. The use of the main screen versus the viewfinder screen can be somewhat annoying (menus and previews show up on the main screen, setting options in the viewfinder) and confusing. More software control of behavior, and/or displaying to both displays simultaneously would have been appreciated.
Summary: Very useful, especially in bright light when it is hard to see the LCD. Well made, high resolution viewfinder. Something that you must have when using long telephoto lenses. Makes it easier to find and follow your subject.
