It’s hard to find a lens that balances cost, constant aperture, and quality. While OEM lenses with constant aperture are top-notch in terms of quality, they often (with the exception of some) come at a higher price point. Sure, you can get away with a lens with variable apertures depending on where you are on the zoom, but you may end up needing a faster aperture even when zoomed in. After the AF motor on my Nikkor 28-70 f\/2.8D<\/a> failed, I was still able to use the lens in manual focus, but after photographing a Christmas play with it, I was starting to get tired of manually focusing it. I went on the hunt for something that wasn’t too expensive but still offered a constant aperture. A chance trip to Burlington Camera landed me on this option. I’ve worked with Sigma lenses in the past, and both have proved to be of excellent quality. This beast, however, is older than those lenses and does lack a few modern features, but it hits all the right notes. It has autofocus, a constant f\/2.8 aperture, and offers good image quality at a price that’s far lower than I expected. Like other third-party lenses, this option comes in a variety of mounts, this one is a D-Type lens in Nikkor F-Mount.<\/p>\n
