NEW : QUICK TEST between this lens and the Lumix pancake 14mm 1:2.5 here :
AT LEAST I've found the PERFECT WIDE SHARP and CHEAP lens for the GH2 !!! It's a C-mount Pentax/Cosmicar 6mm 1:1.2 lens I've bought 9.99€ (12.50$) on Ebay !
The rear barrel had to be modified for 20€ (watch pictures below) to fit on the C-mount to micro 4/3 adapter (Kipon).
This 6mm focal lenght on the GH2 gives a huge vignetting on micro 4/3 sensor, but thanks to the new crop 1:1 GH2 function, the vignetting is disappearing completely !
This 6mm lens with the crop function gives nearly the same frame (same width but less height) than on the Lumix 14mm 1:2.5, but much much more faster.
It's a sharp lens, even with the crop. In 24X36 eq. it's a 30mm.
This lens is incredible for GH2, there is no other competition for such a fast lens !
In this movie you will watch daylight tests (always @ 1:1.2, 1/50 shutter speed, 160 asa) with a 22€ Polaroid 43mm variable ND filter and a 40.5 to 43mm step-up ring, there's my girlfriend preparing her new collection for children "Pitchoovintage".
Then you will watch night test, from 160 to 3200 asa, always @ 1:1.2 and 1/50 shutter speed.
Crop mode 1:1
from 160 to 3200 asa
from 1/25 to 1/50 shutter speed
