Sigma general purpose lenses for Four Thirds DSLRs

Standard zoom lenses offer a general-purpose range from wide angle to short telephoto, thereby giving you great day-to-day flexibility and covering typical landscape shots to basic portrait work. The vast majority of standard zoom lenses in use are those kit models which are popularly bundled with many DSLRs, but Sigma offers a number of alternatives which you may want to upgrade to, or buy from day-one. They include brighter versions of standard ranges, or super-zoom models with massive optical ranges for the ultimate in compositional flexibility.

As always, bear in mind any reduction in field due to your DSLRs sensor when choosing a lens. Models complying with the Four Thirds standard have a reduction factor of 2x, which effectively multiply lens focal lengths by two times. So if you go for an 18-50mm lens, you’ll actually have an equivalent of 36-100mm. For a full explanation of lens specifications and examples of coverage at different focal lengths, check out our Camera Labs Lens Buyers Guide.
