Sigma 440101 Overview

This 28mm lens has a fast f/1.8 maximum aperture, with macro-focusing capability. It features minimum focusing, down to 7.9" with a reproduction ratio of 1:2.9). The 9-bladed aperture diaphragm obtains beautiful out of focus images. It incorporates the floating focus system and the use of two aspherical lens elements to minimize distortion, spherical aberration and astigmatism. The lens incorporates minimum vignetting optical construction in order to obtain adequate peripheral brightness with open aperture. Internal focus system of the lens eliminates front lens rotation, thus allowing the use of a perfect hood and easy use of polarizing filters. The lens also incorporates a dual-focus mechanism. It is easy to hold the lens, since focusing ring does not rotate during autofocus, yet provides adequate torque of the focusing ring during manual focusing. The lens materials used in this new lens are lead and arsenic free ecological glass.

Would you recommend this lens for the Canon EOS 70D for cave photography? I am looking to purchase the camera and lens. The type of photography that I am interested in is nature photography and I am beginner. I choose the 70D because of its articulating screen (touch screen not important), WIFI and GPS ability and most of all because it is weather resistant. The lens that I want for cave photography would be a fast speed wide-angle lens.

This is a great lens for lowlight situations. It will have a 1.6x crop factor on the 70D, so it will be 44.8mm, which is not considered wide angle.
