Canon 40mm STM F/2.8 – Refurbish

Need a lens that’s wide, but quiet for Video Recording.  Canon has a summer sale for refurbish version of 40mm STM F/2.8 pancake lens.  It’s fairly fast for STM since it’s fairly quiet due to it’s design for Video recording, which classic lens is mechanical version, so will have loud sound when turning, and this won’t that issue.  40mm is not to wide, but just okay, it’s in middle of 35mm for wide and 50mm human view.  It may not be as wide as my 16-35mm F4, but with prime, it’s nice size, and compact.  Simply put, to put on a small camera, it doesn’t even look like there is a lens on it.   There are several website that do professional camera & lens review, which will have a lot of information on the lens reviews.

Here is what I got from Canon Website:

A unique and indispensable addition to Canon’s series of EF lenses, the new EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance. The EF 40mm f/2.8 STM’s unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance. Its diminutive design is complemented by features such as a newly developed stepping motor for smooth and quiet continuous AF while capturing video with the Canon EOS Rebel T4i DSLR, a circular aperture (7 blades) for beautiful soft-focus backgrounds, and a short minimum focusing distance of only 0.98 ft./0.30 m.
