Anyone who wishes to make in a very sunny environment with a LX7 or D-Lux 6 images, can not get around this viewfinder. The Panasonic variant is the Leica part already preferable immediately identical construction due to the price. The viewfinder image is thanks to abundant pixels to judge sharp and good, the service (on / off, diopter adjustment) simple and self-explanatory. Four stars are there, because it (also with Panasonic price Bonus) is just too expensive so far to upgrade this part of an already not very cheap digital camera for half of the camera price, that even in very bright environments no longer limited to ratende image design is dependent. Conclusion: a useful accessory for high price, perfect quality.
