New Sigma 18-250mm f/3.5-6.3 DC Macro HSM Review (June 12)

Postby djsquare1827 » Fri Sep 07, 2012 10:54 am

I am in the this dilemma of getting Zoom lens. Started comparing Sigma 18-250mm old Tamron 18-270PZD and Canon 18-200mm. What I have realized after using my Canon 550D with 50mm 1.8 prime lens is people appreciate your sharp photos which makes it outstanding from the normal digital cam. So for me quality and sharpness is everything. While comparing rigourosly from many reliable websites I realized that Canon 18-200mm was scoring the lowest in terms of heavy barrel distortion, sharpness in some test, and couple of other factors. Then I came down comparing Tamron 18-270 pzd & old Sigma 18-250mm in which Tamron was scoring well. I was almost convinced to buy Tamron but then I found out there is a new version of Sigma 18-250mm Macro and OMG I was blown away with the comparisons. Although there is not a huge difference but the the sharpness is well maintained in all the focal lenght across 18-250mm. Below is the link which Iv found out to compare. I have not made up my mind yet but I am highly likely that I would go for New Sigma 18-250 macro lens. I will still wait for some more reviews on Sigma 18-250mm Macro.

With its relatively low price tag and great versatility, the Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM represents a worthwhile all-in-one solution for everyday picture-taking. It's also an excellent choice for travellers who want a single lens to pair with an entry- or mid-level DSLR camera body.
Buy this lens if:
You want a lightweight all-round lens with a competitive price tag.
You want a zoom lens that can be used with polarisers and graduated filters.
You require good flare resistance in backlit situations.
You want effective image stabilisation for both the viewfinder image and the capture system.
Don't buy this lens if:
You have a camera with a 'full frame' (36 x 24mm) image sensor.
You need a fast lens across the focal length range for shooting action in dim lighting. ... view-19470
Superzoom lenses are often full of compromises, but in this 18-250mm lens from Sigma, the compromises are few and far between. It may be the case that shorter zoom ranges may yield better performance overall, but if you're after a convenient all-in-one lens for travel, then the sharpness delivered by this lens certainly makes it worthy of serious consideration, especially when compared to manufacturer’s own superzoom offerings. It's lighter, more compact, cheaper, offers more reach and performs about as well, if not better in some areas.
Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM Pros
Very good performance for a superzoom
Effective optical Stabilisation
Compact size
Light weight
Good build quality
Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM Cons
f/6.3 max aperture at 250mm is relatively slow
No full time manual focus override (which isn't really much of an issue)

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.

Good optical performance for a superzoom
Excellent image stabiliser
Decent build quality
Fast focusing
Zoom creep
Barrel distortion at 18mm

Overall this lens offers a good quality compromise for those looking for a convenient alternative to carrying multiple lenses. Sharpness levels hold up well for a lens of this type and the four-stop image stabiliser greatly increases the usability of this lens making it a perfect travel companion.
Although this lens isn't the cheapest of the bunch, the good build quality and optical performance will certainly make this a compelling choice when compared to the competition. ... cleContent

Test Results:
Distortion: DxO Analyzer 3.0.1 tests of distortion control found Visible-range barrel distortion at 18mm (0.75%), plus Slight pincushioning at 100mm (0.23%) and 200mm (0.20%).
Light falloff: Light falloff was gone from the corners by f/5 at 18mm, f/6.3 at 100mm, and f/8 at 200mm.
Close-focusing distance: At the tight, uniform close-focusing distance of approximately 15.75 inches, magnification ratios ranged from 1:16.9 at 18mm to a gratifying 1:3.16 at 200mm—significantly stronger than the Nikon

Respectable optical performance
Vibration Compensation
Quick, silent focusing
CA levels a little high when stopped down below f/16
Higher price than much of the competition at the moment
Highly Recommended
Super-zoom lenses have garnered a poor reputation for optical quality in the past, but as technology advances, new lenses have been released which change the public's perception of what to expect. This lens is one of those optics. Its lightweight, compact design makes the lens perfect for travel, especially when paired with a more compact SLR body and during testing it proved itself more than capable of delivering excellent quality results, when used within its limitations.
The lens is very new to the market, and so the current street price may seem a little steep when compared to the competition. The extra 70mm, silent focusing and compact dimensions all make a noticeable difference to the usability of this lens and should be taken into consideration when making a buying decision. As the street price drops a little in time, this should certainly make a compelling choice for those in the market for a convenient one lens solution. ... c-pzd-lens
Score - 8.8

You need close focusing and macro capabilities.
You want a lens for a camera with a 36 x 24 mm sensor.
You need a lens with excellent flatness of field for architectural photography and copying. ... -ii-vc-pzd

The member who started this thread no longer has a profile, which probably means he/she will not see your request for more details. Did you notice this is a very old thread topic? Some of the lenses being discussed may well have been superseded by newer versions, by now.

I wish I could contribute, but have no knowledge of these lenses. Gordon did, I believe, a comparative review of three 18-200mm lenses, which included this Canon 18-200mm EF-S, if you want more details.
Canon 5Ds R/7D2/7D/5D/40D/1D2N; Nikon F6/D3s/D700/FM3A/Coolpix A. Lens selection undergoing changes; some favorites: Zeiss 2/135 APO Sonnar, Canon 100mm f/2.8L Macro IS and 135L, Nikkor 14-24/2.8G and 200/2 VR.
