The A09NII SP AF28-75mm F/2.8 XR Di LD Aspherical IF Macro zoom lens is a lightweight and compact standard zoom lens compatible with full-size SLR cameras, and features a fast maximum aperture of F/2.8 that is constant over the entire zoom range, with a built-in AF motor for use with Nikon cameras. The lens enables users to enjoy the creative world of SLR photography, by exploiting the attractive out-of-focus effect particular to fast maximum-aperture lenses seen in portraiture, or when using high shutter speeds. The optical system is designed to optimize the power distribution within the system by the innovative employment of XR (high refractive index) glass elements. The SP AF28-75mm F/2.8 XR Di sports the minimum focus distance of 0.33m over the entire zoom range, the closest distance among fast standard zoom lenses in its class. The maximum magnification ratio of 1:3.9 at the 75mm tele end enables you to enjoy close-up photography easily. The lens is supplied with a flower-shaped lens hood as a standard accessory, which is designed to efficiently cut harmful light entering from angles other than the intended angles at the four corners of the frame, in order to ensure clear descriptive performance. The lens has a built-in zoom lock mechanism to prevent sliding fall of its barrel when the outfit is carried around. 14 groups 16 elements lens construction Dimensions – 3.62 2.87 (9273mm) Weight – 510 grams (18 ounces)

The Lensbaby 3G lens is a workhorse for photographers who require precise focusing, complete control, longer exposures, and repeatability. When working with dynamic subject matter you can focus Lensbaby 3G just like Lensbaby 2.0 – by compressing and bending. For slower moving or static subject matter, you can lock the lens in place simply by pressing a button on the focusing collar. Then you can fine focus using a traditional barrel focusing ring and fine tune the tilt to place the sweet spot exactly where you want.Lensbaby 3G features the same low dispersion, high refractive index, multi-coated optical glass doublet as Lensbaby 2.0, and delivers images with a tack sharp sweet spot with minimal diffusion even at the f/2 aperture setting. Lensbaby 3G uses the same system of magnetically levitating aperture disks as Lensbaby 2.0 with aperture settings of f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, and f/22.
