@ dhessel: 
i have also a kowa 16 lens :) but its too wide for my taste..  
i tried the iscorama it with the original prime lens from iscorama, a jupiter-9 85mm, super takumar 55mm, helios 44, super takumar 85mm.. 
all the same..  
  
@Gabor: 
yes this little thing is really funny, perhaps they will eventually offer a raw video app with cdng output some day.. :) 
  
  
thx.
