Sigma 24mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Sigma SLR Cameras
I purchased this lens, then barely used for the first few months. One day I was in a creative rut, so I decided to spend a day taking photos with only the lens I used the least. That day resulted in this becoming a favorite lens. On my 40d it's equivalent to around a 38mm focal length, which I find to be quite versatile.
This is one of my sharpest lens, and the wide aperture is really a pleasure to work with creating a nice bright viewfinder and great bokeh. I find the lens to be quite usable opened up all the way to 1.8, but stopping down to 2.0 or 2.8 does make a noticeable difference in sharpness. It can close focus much closer than the specs suggest,within 2-3 inches from the front element. The autofocus of course is much slower than USM/HSM but really isn't that bad in practice so I have no complaints. Switching between auto-focus and manual is a little weird. First you have to hit the typical MF/AF switch, then push/pull the focus ring to the AF or MF position. I find this two step process to be quite annoying. However the focus ring is nice, large and well damped making manual focusing pleasant. On a crop body like my 40d, I see no noticeable vignetting or corner softness, but I haven't tried it full-frame. It is large an heavy, but that's what you get with such a wide aperture combined with the sharp optics. I am glad it has a normal 77mm filter size. My biggest complaint other than the AF/MF switch is that Sigma makes some of the worst lens caps, it's really a pain to put the cap on or off with the lens hood attached. One of these days I'm going to replace it with a good center-pinch cap to make life easier.

"Sigma 24mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Sigma SLR Cameras" Overview
Sigma 24mm f1.8 EX DG Aspherical Macro is one of the EX Series lenses. This lens has a fast F1.8 maximum aperture with macro focusing capability of minimum focusing down to 18cm/7.1inches (reproduction ratio 1:2.7). The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus image. It incorporates the floating focus system and uses two aspherical lens elements for minimizing distortion and spherical aberration and astigmatism. Internal focus system eliminates front lens rotation, thus allowing the use of a Perfect Hood and the easy use of polarizing filters. The lens incorporates non-vignetting optical construction, in order to obtain adequate peripheral brightness even at open aperture. This is desirable for digital cameras. The lens also incorporates dual-focus mechanism. It is easy to hold the lens, since focusing ring does not rotate during auto-focus, and yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The lens materials used in this lens are lead and arsenic free ecological glass.

Value Proposition - David Garfinkel -
Fast lenses and fourthirds usually dont go together in the same sentence, barring the a few of the ultra expensive zuiko zooms and the 50mm macro (hunter). This is a great lens for a great price. As an Oly user I dont feel its worth it to spend 1k or more on a pro quality lens when the bodies, as much as I love them are lagging behind the glass. This sigma is a good choice for a wide portrait lens but i wouldnt say its really a macro, not when compared to my nikkor 55mm 2.8 that gives me 1:1 with crop factor.
The quality of this piece is great and it really feels like a real lens. I know smaller and lighter is the point but this is a big piece that feels solid as any Nikkor. A bit loud but at a wedding who cares. Great colors, sharp or sharper than the Zuiko 50mm f2, and just a great buy all together.
Go Sigma for taking a chance on fourthirds! There are not enough reasonable choices unless you use converters and vintage glass as Ive been doing for the past several years.
I would recommend this lens for anyone who wants a fast good old school feeling prime for parties, general wides, bouquets (tough to get with the extra dof you get from the fourthirds sensor).
Great buy!
