Summary: Viewing photos with this EVF is like going to the cinema. The screen is amazingly sharp. The color gammut is greater than on the camera's own display, allowing it to show bold colors that other displays can't show. All this is extremeley helpful when composing pictures. As with all LCD displays, the blacks are noticably grey, so an AMOLED display is on my wish list for the next model.
Summary: I have nothing to add to the other comments, as they pretty much sum it up. This viewfinder is top notch. KEEP IN MIND, though that the image quality will be degraded on older, 12mp generation Olympus Pen cameras, all EXCEPT the E-P3 and E-PL3. Long story short - the image quality in the viewfinder will be less stellar when used on the E-PL2, E-PL1, E-PL1s, E-P2 and XZ-2, compared to what you will see in a E-PL5, E-PM2, E-M5, E-PL3, E-PM1, E-P3.
Summary: I have to start this review with a WOW! This viewfinder is amazing! I upgraded my e-pm2 (pen mini 2nd gen) to the latest firmware because I read it needed it. Popped the viewfinder on and that was it! I have a D600 full frame camera and I have easier time getting critical focus with this thing (when manually focusing) than with the optical viewfinder on my D600.
Summary: Since first buying the Oly EPL-5 I had planned to eventually add a viewfinder to my kit - although the camera screen is quite good overall, for some operations such as manually focusing on a small subject on a sunny day, I still missed having a VF. Since it locks in place on the camera like the VF3, but has about 60% more resolution than the VF2, picking the VF4 was an easy choice. A quick update of the EPL-5 firmware to v. 1.2 had me ready to use it in a few minutes.
Summary: I grew up with SLRs and don't feel comfortable or steady composing with a LCD at arm's length. So I bought the VF-4 EVF to use on my Olympus Pen E-P3. I updated camera firmware to 1.7, slid on the VF-4 and was propelled into eyeball Nirvana! CONSTRUCTION This designed in Japan born in PRC viewfinder is plastic and finished in a grippy flat black finish. It appears well made but looks a little out of place against the brushed aluminum of my E-P3.
Summary: I bought this to use with the new E-P5 which I do not have yet. I updated the firmware on my E-M5 to 1.7 and the VF-4 works very nicely on the E-M5. It gives a more detailed view than the built-n E-M5 finder but I doubt it is a more accurate view as far as exposure and color. I am using it mostly for photographing flowers and landscapes in the bright sun.
Very impressive EVF, quite a bit better than previous models

Summary: I have had both the VF-2 and VF-3 for my Olympus M43s, and have also been using Panasonic M43 cameras with integrated viewfinders for a while (GH2; GH3; even have used the LVF-2 on a GX1). In past, I have preferred the Panasonic viewfinders, simply because they have a larger magnification/larger view than the Olympus versions, and are easier to see. However, the VF-4 changes all that.... Very simply, this is the best EVF that M43s cameras have ever had.
