Sigma Wide Angle 28mm f/1.8 EX DG Aspherical Macro Autofocus Lens for Pentax AF
( Focal Length: 28mm )
Sigma W/A 28mm f/1.8 EX Aspherical DG DF Macro AF Lens Sigma W/A 28 mm f/1.8 EX Aspherical DG DF Macro AF Lens 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.

review from Amazon User
Pros & Cons :i first put it on my 5d and had a few shots.
Am I the only person who is having "ERR" with this lens?
...I wondered if it is not compatible with full frame body.... Wait, it is DG, which is made for both image sensors.Well, then I put it on my 40D. Guess what? Same thing happened again. "err" after a ... read more

review from Amazon User
Pros & Cons :an easy adjustment of the calibration setting in my camera took care of the problem and everything is hitting bulls-eye after that.
...If you aren't careful with the composition and have the subject too close to your lens, then the 28mm will cause the subject to have a big & round face. As for DOF, I calculated that a 28mm at f/ ... read more

review from Amazon User
Pros & Cons :this is currently my favorite lens in my modest collection.
...I can't comment on the edge sharpness for full frame because I haven't used it with one of those bodies. On my D90, however, it ROCKS. It costs a fraction of what the now-discontinued Nikkor 28m ... read more

Pros & Cons :so your out of focus landscape shot would be a result of user error, not the lens.
...not suitable for landscape unless you up the F-stop) cons: bigger than canon prime lenses (except L primes). I definitely recommend this as an ideal lens for close to 50mm point of view on a cro ... read more

Pros & Cons :all i really have to say is i love this lens, amazing macro, great for landscapes, and portraits come out very nice as well.
...I highly recommend. Only issue I have come across is with the cameras built in flash when used for macro while using flash the lens lip blocks a bit of the flash but that doesnt bother me seeing a ... read more
