Great image result for an APS-C style of camera. Used extensively on a major holiday in Europe the lens proved itself. The only downside is 'lens creep' as set in and the 'lock' must be placed on at all times if the camera is facing towards the ground when being carried.
Easy to use
Build quality
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.
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...
There is an underlying desire in every travel or street photographer to be able to carry one lens to cover all contingencies.
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
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.
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
Very convenient lens. Get this one with my 500D is a nice combo. No need to change between the 17-55 IS and 70-200 L as before. I can leave the two lenses at home and travel light with only one lens. IQ is OK.
Very useful zoom range; fast and near silent focus; reasonably sharp from 18-80 mm
