Canon EF 40mm f/2.8 STM Lens – Fixed

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.1-Year Warranty

    At long last, a Canon pancake lens for SLRs. “Pancake” lenses have always had an appeal to SLR shooters. Their dimunitive size and weight, as well as overall simplicity, make them ideal as walkaround lenses, and many find the focal length of 40mm (give or take a few mm) much to their liking for general photography. Contax, Pentax, Nikon and other manufacturers have produced their offerings throughout the modern photographic era. Panasonic and Olympus have pancake lenses for their micro 4/3 lenses. For some mysterious reason, Canon has…

    Great Lens (Even Greater for Full-Frame Cameras) Before going into the details of my review, I’d like to start off by saying…if you have the money on hand, you should immediately buy this lens. I am extremely pleased so far – this is a lightweight, yet solidly built, and extremely affordable performer. While two hundred bucks doesn’t seem “affordable” at first, it delivers very solid results that you could expect from lenses that cost several times as much.To give some background: I do shoot professionally, but got this lens…

    Small in size but great in features and quality Please don’t take the Amazon star rating too serious – every lens has its pros and cons that I wouldn’t want to squeeze into a single one-dimensional figure…A quick note about me: I have been into SLR cameras and lenses for more than 20 years – as a hobby in the beginning and professionally later. Maybe because of my technical background I started testing my own lenses quite a while ago. I have a (no longer so) little test lab of my own where I do 6 different image quality tests (after…
