"It all starts with the glass". How true! In today's High Definition world this phrase could not possibly be truer. The effect of poor quality lenses and lens accessories will be multiplied in HD. Only glass specifically designed for High Definition use will be good enough. Consider the finest grade glass, cutting edge HD design, low geometric distortion, good off-axis performance, low chromatic aberration and flatness of field.
