When it comes to all around versatility, there’s no other type of lens that packs as much creative and compositional flexibility into a compact package as the high-zoom ratio multi-purpose zoom lens. If you want to travel seriously light, but pack a lens that can go from wide angle to telephoto with just a twist of the zoom ring, an all-in-one lens is the way to go. Sigma currently offers three all in ones, the 18-200mm, the 18-250mm, and the 18-300mm.
All in one zoom lenses maximize the possibilities of variable aperture zoom lens design to cover a great focal range in as compact a package as possible. While the size, weight and total zoom ratio varies slightly between each of these camera lenses, each lens offers fantastic performance across a wide zoom range, effortlessly switching from a sweeping field of view to the long-reach pinpointing of a distant detail.
High zoom ratio lens design has evolved significantly in the past couple of decades, and the total image quality throughout the focal range has benefitted greatly. In fact, in 2012, respected photography site DPReview said they thought the Sigma 18-250mm was the “best-rounded general-purpose SLR lens currently on the market.”
In other words, all-in-one lenses are designed to be multi-taskers, well-rounded lenses adept at a number of styles of photography. You can think of these as the pint-sized gold-medal decathletes of the lens world—wide angle for landscape and group shots in tight quarters one minute, switching instantly to long-reach telephoto for sports and wildlife, and focusing much closer, to true macro capture at 1:3 magnification and above!
True, a prime lens is going to offer a bit sharper performance and shallower depth of field at its single focal length, and a dedicated macro is going to offer life-sized magnification; but when it comes to total versatility and flexibility, the all-in-ones simply can’t be beat.
These are the perfect, lightweight, single-solution lenses for the on-the-go photographer: moms and dads looking to capture their kid’s adventures, college grads on a cross country adventure, retirees on a dream cruise, for example.
So which Sigma all-in-one camera lens is right for you?
The smallest and lightest of the three all-in-one lenses in the Sigma lineup, this lens offers an 11.1x zoom ratio (28-300mm equivalency) and 1:3 macro magnification, along with Optical Stabilizer for sharper handheld shots without a tripod. And it does it all in a lens that is less than three and a half inches long in the camera bag, and weighs in at just shy of one pound. Tiny, yet mighty!
Offered right now with incredible Instant Savings, this is the most economical of Sigma’s high-zoom ratio lenses. Called “the best-rounded general-purpose SLR lens currently on the market” by DPReview, this was the first Sigma lens to incorporate the new Thermally Stable Composite into the lens construction. With a 13.8x zoom ratio (28-375 equivalency) and 1:2.9 macro magnification, and Optical Stabilizer, this is a lot of performance in a 3.5 inch long lens weighing in at just over a pound (16.6 oz)!
The newest all-in-one in the Sigma lens catalog offers the highest zoom ratio with a 16.6x range between wide angle and supertelephoto (28-450mm focal range equivalence on the APS-C sensor). Straight out of the box, it offers 1:3 macro capabilities, it can go to 1:2 magnification (one-half life-sized) with the optional dedicated close-up accessory lens. And of course, it offers Optical Stabilizer for sharper handheld shots at slower shutter speeds.
