Yasuhara Nanoha x5 Macro Lens 5:1 - micro 4/3 mount - CLEARANCE
Heart of the NANOHA x5 consists of ten spherical glass lenses arranged in seven groups. Individual elements are coated by one or more surface layers, which prevent reflection and mechanical damage. It is possible to focus in a 11 to 19 mm range with resulting 4x to 5x magnification, that is 4:1 and 5:1 magnification.
The body of the lens is mostly metal, excluding the LED illumination module and the material of the mount differs depending on the camera type. The mount is made of steel on the Sony NEX (E-mount) and of aluminum on the micro 4/3. The removable light module includes 3 LEDs, whose running life is thousands of hours according to the manufacturer. The lens was designed in Japan and manufactured in China, but before sale every single piece undergoes a final inspection in Japan.
Based on our own experience (365astronomy), best results can be achieved when a large focal ratio is used, 22 or 32, especially when you don't want to take too many photos. In this way you can use less photos to stack together...
The only problem with this approach is that you'll have to use a comparatively high ISO or low speed. if low speed is not a problem lower ISO is better to be used, however, if vibration is a problem due to the environment or your equipment (tripod etc), then use high ISO and faster exposure...
