The Sigma 30mm f/2.8 is one of the very best bargains in the photographic industry. It’s a very inexpensive lens ($199 retail, on sale at the time of this writing at $169), but packs serious imaging capabilities. The lens is small, light and puts out images with very high levels of detail right from f/2.8. Stopped down a bit yields excellent cross-frame sharpness and high contrast photos. While there are a few small things like a bit of barrel distortion and a not-so-fast autofocus system, overall, it’s hard to get a better lens for the price. Frankly, in many ways, it’s hard to get a better lens for three to four times its price. Sure, it’s not the fastest normal focal length lens in the world, but if you are OK with an f/2.8 aperture, it’s worth your money to get this lens. A simply top-notch effort from Sigma.
