Amazing! What an excellent camera hacking job by that Chinese hacker/maker! Now you can enjoy all these functions with Pentax K-mount lenses on Canon EOS bodies. The aperture and focal will be recorded in EXIF and metering will be more accurate! The Pentax lenses can now be even focus adjusted on EOS bodies, which "genuine" Pentax users could not even do this and enjoy this "pro" feature on entry level or older K-mount Pentax DSLR bodies! :-o
