sigma 4.5 mm lens for pentax KxHi; I would like to buy a sigma 4.5mm lens for my pentax kx; I think I will not have full circle with sigma 8mm.
What do you think about this lens un my aps-c.
Will I have good panorama?
I have a 10-17 mm pentax lens know; but it is too hard when I have to make a virtual tour with many places.
here you are link of lens:
thanks a lot
