Useful but expensive accessory. I bought it to use with my XZ2. Useful for very precise framing, but does not reflect the exact colorimetry (bluish color picture in the viewfinder), do not correction from the viewfinder. Moreover, it is a pity not to be able to buy it in gray (my device is black). Warning, it seems a little fragile, all plastic. I wish the diopter adjustment dial either with firmer notches, the setting is not resistant to manipulation of the unit. Despite its few flaws, I recommend it if one wants to work its framing. Expensive! For 150, we could have a much higher quality. The question is how he will grow old!
