Review summary from DPReview

Sigma 18-250mm f3.5-6.3 DC MACRO OS HSM
DPReview TestedNovember 2012
The Sigma 18-250mm is compact, has decent enough optics, offers fast autofocus and effective image stabilization, and tops this all off with impressive close-up ability. We'd be inclined to conclude that it's the best-rounded general-purpose SLR lens currently on the market.

Product Description

18-250mm f3.5-6.3 DC MACRO OS HSM

From the Manufacturer



High Performance, Compact, High Zoom Ratio Lens designed exclusively for digital SLR cameras

By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM, this new lens achieves a compact size and a minimum focusing distance of 13.8". New material, Thermally Stable Composite (TSC) maintains its structure and has little contractility especially in varying temperatures, is incorporated into the lens barrel. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.

A wide range of photography is possible in one lens

Covering wide angle 18mm to telephoto 250mm, this versatile lens designed exclusively for digital SLR cameras, is suitable for all-purpose photography including landscape, sport, and macro photography. It is convenient when you wish to keep your equipment to a minimum and yet still be prepared for all opportunities and situations, such as travels.

Excellent for macro photography

Close-up capability is improved with the minimum focusing distance of 13.8" throughout the entire zoom range, and maximum magnification ratio of 1:2.9. In APS-C size equivalent, macro photography with approximately 1:2 magnification ratio is possible. In addition, with this lens, the size and flaming of subjects can be adjusted by rotating a zoom ring, making macro photography easier than using fixed focal macro lens. For further convenience, the maximum magnification ratio at each focusing distance appears on the side of the lens barrel.

New design. Compact size.
New design. Compact size.
Revolutionizing the design foundation results in compact size

Optimization of the power arrangement by such things as incorporating double-sided aspherical lenses, and reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately 13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 2.9" x Length 3.5". It ensures portability and overall ease of use, making it perfect for travel and leisure photography.

New material TSC (Thermally Stable Composite)
New design. Compact size.
Thermally Stable Composite

The new material "TSC (Thermally Stable Composite)", which has little contractility especially in temperature changes, as well as maintaining firmness, is incorporated into the lens barrel. Compared to Polycarbonate which is generally used, TSC has higher elasticity by approximately 25%. Since thermal shrinkage is low, it has high affinity to metal parts which contributes to high quality product manufacturing. It also contributes to the parts such as the zoom ring and scaling to be slimmer

Lens Construction
Lens Construction

In a conventional lens, focusing requires an extension of the entire lens or the front lens group. However, to better accommodate autofocusing mechanisms and closeup photography, a need has arisen for lenses that do not change their length during focusing or suffer from focus-dependent variation in aberration. Therefore, Sigma has developed focusing systems that only move elements within the lens barrel. These incorporate smaller and lighter moving lens elements which help improve auto-focus speed. With their unchanging barrel length and small variation in the center of gravity, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.

MTF Chart

MTF (Modular Transfer Function) is one of the measurements that evaluates a lens' performance, and it contrasts sensitivity at different spacial frequencies. The horizontal axis is in millimeters and shows the distance from the center of the image toward the edges, and contrast value (highest value is 1) is shown in the vertical axis.

The readings at 10 lines per millimeter measure the lens' contrast ability (red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens' sharpness ability (green lines), when the aperture is wide open. Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the frame, are called Sagittal lines (S) and sets of repeating lines vertical to these lines are drawn, called Meridional (M) line sets.

Distortion

effective distortion: When you take a picture of a lattice pattern, it will appear as the blue dotted line shows. the red line illustrates how the lattice pattern will appear in the actual picture when any lens distortion is taken into account.

relative distortion: In this chart, the horizontal axis shows the ideal image height (the distance from the center to the edge of the image [mm]). The vertical axis shows the extent of distortion. The extent of the distortion is represented by how much Y, which is the actual image height, grows (or shrinks) against Y0 which is the ideal image height.

Extent of distortion: D[%]=(Y-Y0/Y0)x100

When you take the picture of a square object, if the distortion amount show a minus value, the image will be seen as expanded (Barrel distortion). If the distortion amount is a plus value, it will be seen as a recessed (pincushi on distortion). When the distortion value is close to 0, the appearance of distortion is very minimal.

Vignetting

The horizontal axis shows the image height (the distance from the center to the edge of the image [mm]). The vertical axis shows the amount of light in the image (based on the amount of light in the image center being 100%). If the peripheral amount of light is lower than the center, the four corners of the image will be darker (vignetting).

Style Name: Canon SLR Mount Verified Purchase
I am very very pleased with this newest superzoom from Sigma, paired with my Canon 60D. Build quality is excellent. Image quality is sharp at both ends of the range. Focus is quick and quiet. OS works extremely well. It is light weight and compact compared to others in this category, which adds to its value as a "walkaround" lens. To top it all off, the price is outstanding for a lens with this feature set, build, and image quality. (It's ~$100 cheaper than the "comparable" Tamron, and ~$30 less than the shorter focal length Canon 18-200.)

I had used the Tamron AF 18-270mm f/3.5-6.3 Di II VC PZD LD Aspherical IF Macro Zoom Lens for Canon DSLR Cameras for a while last year, when it was the "hot" 3rd party superzoom. But, the images looked a little soft to me, especially at the long end. Plus, I didn't care for the build quality and feel of the zoom/focus rings at all. (The Tamron is made in China, while this Sigma is made in Japan.) And, IIRC, the Tamron zoom ring operated in the opposite direction from Canon and Sigma, which wreaks havoc with one's muscle memory. The Tamron also suffered from lens creep, which the Sigma, so far, has not.

I have been using the Canon EF-S 18-200mm f/3.5-5.6 IS Standard Zoom Lens for Canon DSLR Cameras with my 60D until switching to this Sigma, and the Canon EF-S 18-135mm f/3.5-5.6 IS Standard Zoom Lens for Canon Digital SLR Cameras with my T2i before that.

Style Name: Canon SLR Mount Verified Purchase
I'm reading all the other reviews here saying to myself "are these folks really taking this much time and energy nit-picking over small reductions in image quality, or why this lens is not ACTUALLY 250mm but more like 239mm?!?"

Look at the facts - this lens is only $400 AND it's got a huge range, optical stabilization, an equivalent USM super-quiet motor, and capable of sharp, clean images!

Judge things on their own merits, not compared to lenses 6-8x the price. Some of these other reviews are actually akin to "I bought this Camaro for $35,000 and was duped into thinking it handled nearly as well as a Lamborghini Aventador at $375,000."

Will you get superior images from L-series glass? Every time. Is the auto-focus USM from Canon superior? You bet. Is the IS quieter than the OS from Sigma? Sure is. Is the low light performance of this lens inferior to the Canon counterparts at 3x the price? You know it.

BUT....

If you are on a budget AND are willing to compromise a tiny bit in each of these areas will you get a lens that comes very close to it's competitors for a GREAT DEAL LESS?! Of course!

Enough said. Get the lens, you'll be happy.

-- UPDATE 19-OCT-14 --

The lens is still going strong, of course.

One thing to bear in mind - if you are using this lens on a crop sensor body (Rebel series, xxD, 7D or 1D) you are getting a magnification factor of 1.6. This means that a 250mm lens is gaining a reach similar to a 400mm lens. I say similar because on a smaller sensor you are not actually getting the 400mm - it's a cropped, or smaller amount of the image.

Style Name: Nikon SLR Mount
I wanted a solid walkabout lens for my D5100 without breaking the bank. I had the option of buying the Nikon 18-300 for about $1000 or a 3rd party lens. I really did't want to invest too much in glass for a D series mount as I can see myself moving up to an F series in a couple of years. I was sick of changing lenses and lugging a lot of weight around and really wanted a zoom in this range.

After doing research online I decided to go with the Sigma (over the more expensive Nikon and competing Tamron). Their reviews were solid, and I have previously owned and been satisfied with Sigma lenses.

Here is the scoop:

Pros:
1. Fast, accurate, quiet autofocus (faster that the stock Nikon lenses which came with the camera (18-55 and 55-300).
2. Light weight, well built, well balanced, and ergonomically superb in every aspect.
3. Image quality is awesome (for a super zoom).
4. Image stabilizer does the job with at least 3 f stops improvement.
5. I love the internal manual focus mechanism, it is definitely an upgrade over basic Nikon lenses. Easy and fast to use.

Cons: The only thing I can say so far is there is lens creep. Actually more than creep. The front portions of the lens will extend halfway out while the camera is hanging from my neck. The good part is there is a very convenient lock that prevents this from happening when you are walking around. For me personally, lens creep is not an issue. I haven't bought this lens for tripod mounted macro photography. Be pretty sure that any such lens will have creep; If not right out of the box, sometime within a few months of usage. You can always send the lens back and they will tighten it, but the creep will again come back in time and warmer weather.
