Like all super zoom lenses, the Sigma 18-250mm f/3.5-6.3 DC OS HSM Lens features a to-die-for focal length range . Sigma packages this 13.9x (250mm divided by 18mm) focal length range in a very well built , modestly-sized , reasonably-priced APS-C-only lens with quiet, fast AF and optical...

Yes, I would recommend this to a friend

Fast / accurate auto-focus; Strong Construction

Full zoom light loss

I bought this as a general purpose lens for my D90. I had been using a Nikon Nikkor 28-80mm lens. This is a huge upgrade for me in picture clarity and zoom. OS works great and there isn't much zoom creep as is complained in some review on the web. I am very happy.

At 13.8X, this digital-only 29-400mm equivalent (on DSLRs with 1.6X lens factors) offers the broadest zoom range of any Sigma lens. Joining Sigma's first digital-only superzoom of 2004, the 18-200mm, this $530 (street) lens adds optical stabilization (OS), four elements of super-low-dispersion glass...

Very versatile walk around lens. just like carrying 18-55 + 55-250 with a tripod.

good built quality; effective OS; HSM motor; very good IQ between 18-80

quiet heavy; average IQ between 135-200

Handling and features Performance Verdict Specification This 13.8x superzoom lens is compatible with Canon, Nikon, Pentax, Sony and Sigma DSLRs that have an APS-C sized sensor or smaller.

Very good performance for a superzoom; Effective optical Stabilisation; Compact size; Light weight; Good build quality

f/6.3 max aperture at 250mm is relatively slow; No full time manual focus override (which isn't really much of an issue

The barrel has a large zoom ring and a small manual-focusing ring at the front, with a zoom scale marked at 18, 24, 28, 35, 50, 80, 135, and 250mm. The three switches on the barrel include Zoom Lock, AF/MF, and stabilization ON/OFF.

Photographers often have to compromise when it comes to third-party lenses, particularly ones that cover such extreme focal lengths as the 18-250mm. This Sigma model is excellent value for money, offering good sharpness and performance, with a lengthy zoom.

Very lightweight and compact; Pleasing bokeh; Excellent sharpness at the telephoto reach

No manual focus override in AF mode

The perfect lens for those wishing they didn't have to change lenses all the time. We bought this to replace our two lenses and it worked out nicely. Takes perfect pictures and is easy to operate. Would recommend this to anyone.

Sigma's DC 18–250mm f/3.5–5.6 Macro OS HSM lens is designed to be an all-in-one lens and the focal length is one of the widest available on the market. It was specifically designed for use with an APS-sized sensor, which makes it more like a 24–300 lens, depending on the crop factor of the camera...

Light; Big zoom range; Pretty good image stabilization

Soft edges; Significant chromatic aberration
