About this site

Pentax DSLR cameras are known to be very good performers.

Many also know that Samsung GX10/GX20 are almost the same cameras.

Unfortunately these cameras have many points that need improvement.

Despite being one of the best cameras to work with manual lenses, this area could be improved greatly.

Pentax K10D/K20D and Samsung GX10/GX20 uses same processor and many parts are similar. This could make our work faster.

K7 still use similar platform and the sensor is very similar.

And we have openly released firmware for K7 already.
