One of the nicest focal fixed lenses produced by the Panasonic Compact System is the Lumix G 20mm F1.7 referred as « Pancake » by many users. Although it is not part of the usual kit proposed for the Panasonic m4/3 cameras like many standard zoom lens such as the 14-42mm the Lumix 20mm F1.7 has been combined with the Lumix GX7 for example as a standard lens.
|Foreground/Background In-Out Focus|
The angle of view of the Panasonic Lumix G 20mm F1.7 is similar to the one you got for your own vision if you concentrate on the detailed part (in focus) area. So it is a very predictable lens that will allow you to anticipate your composition without constantly using to the viewfinder or the screen of the camera.
|Typical Lens Flare|
I have read from one respected reviewer that the lens is very sensitive to lens flare phenomena when it is exposed to direct source of light like the sun. Every lenses will present some kind of lens flare over different contexts and because of the very compact (flat) optical design of the Lumix G 20mm F1.7 it is a normal to get lens flare. Since I am somewhat more experimented with optical physic I recommend using your hand as a “flag” (like we use to do during studio photo sessions) to counteract this effect.

service for most of the time.
|No more lens flare by using your hand as a flag.|
At the end and considering the photographic value of the Panasonic Lumix G 20mm F1.7 it is really a good opportunity at a small sales price to get access to a very good photographic tool.
