technology provides photographers with superior super-telephoto
performance in a smaller and lighter design with enhanced correction
for chromatic aberrations. We’ve also added our highly effective
Image Stabilization system that gives the equivalent effect of
a shutter speed two stops faster. And, it’s built to our professional
standards with fast AF, full-time mechanical focus and dust and
water-resistant construction. |
