Lens Description: A worthy successor to the popular Canon EF 300mm f/2.8 IS, the all-new Canon EF 300mm f/2.8 IS II USM super telephoto lens is lightweight, weighing approximately 13% less than its predecessor, yet offers faster operation, improved image stabilization and superior optics. Incorporating Fluorite elements for improved image quality and reduced chromatic aberration plus a number of advanced coatings to minimize ghosting, flaring, and with a newly developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, the EF 300mm f/2.8 IS II USM is ready to deliver spectacular images in an instant. With a third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed, and giving the equivalent effect of a shutter speed four stops faster, the EF 300mm f/2.8 IS II USM allows for easy panning and is ideally positioned for professional action photography. The EF 300mm f/2.8 IS II USM also features a new security slot for wire-type security locks.

Nikon AF-S NIKKOR 28mm f/1.4E ED


Nikon AF-S NIKKOR 28mm f/1.4E ED

Lens Summary

Brand: Nikon
Also Known As: Nikon 28mm f/1.4E
Lens Type: Prime Lens
Format: Full Frame / FX
Focus: Autofocus
Lens Mount: Nikon F
Release Date: 31-05-2017
Made in: Thailand
Production Status: In Production
Lens Description: A fast and versatile wide-angle prime, the AF-S NIKKOR 28mm f/1.4E ED from Nikon is a flexible lens designed for FX-format F-mount DSLRs. Pairing with the comfortable focal length is the bright f/1.4 maximum aperture, which benefits working in low-light conditions and also offers increased control over depth of field. The optical construction utilizes extra low-dispersion glass to correct chromatic aberrations and color fringing for notable clarity and color fidelity, and a Nano Crystal Coat has also been applied to suppress lens flare and ghosting for greater contrast when working in strong lighting conditions.
Photography Life Review Summary: Nikon stuffed the 28mm f/1.4E with everything in its arsenal to make it an outstanding lens and it certainly paid off – I am sure that for many years in the future, it will be regarded as one of Nikon’s finest. And that’s what I expected to see from this lens in the first place…after-all, the Nikon 28mm f/1.4D it replaced had always received high praises from photographers all over the world, so it had to live up to those expectations.
