The tokina October 17 is really an interesting perspective! Very versatile, it is capable of having an amazing deformation without vignetting, and simultaneously to contain well over its longer focal! Even when it is noted that for the optical fisheye genre, we can only settle for f: 3.5, making the little optical performance from a significant decrease in brightness! So we need to lower the speed or increase the sensitivity exponentially! Otherwise very fast receiving and packaging quality, as usual :)
