This rectilinear 15-30mm f3.5-4.5 Ex Aspherical DG DF lens provides focal lengths from 15mm ultra-wide angle to 30mm wide-angle and is the first of its kind in the world. This lens has minimum focusing distance of 11.8 inches (30 cm) at all focal lengths with 110.5 degrees (wide) to 71.6 degrees (tele) of angle of view. (Maximum magnification is 1:6.) It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration.This lens equipped with dual focus mechanism and also inner focusing system. It is easy to hold the lens, since the focusing ring does not rotate during auto focusing, and yet it provides adequate torque of the focusing ring during manual focusing the lens.This lens is desirable and for digital SLR cameras also.

This lens is all about a wide view for a full frame camera. It does this quite well. I use it on a Canon 5D Mark II. While the combination is heavy it is still comfortable to hold. Using a lens like this demands that you get close to the subject especially at 15mm. Great for landscape and architecture as long as you hold the camera level. Avoid shooting into the sun, as with all super wides the lens flares. Do you need a lens this wide? Probably not. Do you want one? Yeah.

Wide eyed

This lens is absolutely necessary for its flexibility with the digital 1.6:1 aspect ratio.

There is no fall-off at the edges as there is with many wide-angle lenses.
