Summary:This model has been tested by our experts.
The Sony SAL 18250 DT 18-250mm f3.5-6.3 is part of the SLR lens
test program at Consumer Reports. In our lab tests, SLR lens
models like the SAL 18250 DT 18-250mm f3.5-6.3 are rated on multiple criteria, such as those listed below.
Image quality:
Image quality is based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance.
Modulation transfer function:
This is a measure of lens performance and shows how well a lens reproduces object detail in the image it produces.
Geometric distortion:
All lenses have degrees of geometric distortion, which will depict straight lines as slightly curved. Two most common types are barrel distortion and pin-cushion distortion. These types of distortions are often seen in zoom lenses at both ends of the zoom range.
About This Brand
Sony has only been in the DSLR game since 2006 but it has quickly become a major contender. Sony purchased DSLR technology from Konica Minolta in June 2006 and then produced its Alpha series of digital SLRs using some of Konica Minolta's camera innovations. Sony's Alpha cameras use the Konica Minolta lens mount and so are compatible with older Minolta auto focus lenses and Minolta lenses rebranded under the Sony name. Sony currently has more than 20 lenses in its stable, including several premium models that were developed for Sony by the German lens manufacturer Carl Zeiss. Other Sony categories for lenses are: zoom, fixed focal length, macro-STF-reflex-fisheye, and G lenses (professional).

Zoom ratio The zoom ratio is expressed by a value such as 2x or 3x, and describes the relationship between the longest and shortest focal lengths. For example, a 3x optical zoom with a minimum focal length of 18mm would have a maximum focal length of 54mm.

Weight (oz.) Weight of the lens (without case, pouch or filters).
The is a good reasonably priced lens upgrade from the kit lenses that the lower priced Sony cameras come with. This is a good lens to use if you are doing a wide range of photography and do not want to change the lens for varying distances. It is fast to focus and is easy to use. The only con, other than being heavy, is that the focus is a little lengthy in dark/dusk conditions.
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

Excellent Zoom range!!

Strength
Very good zoom, leightweight compared to other lens in this zoon range, very good quality photos.
Weakness
Expensive
I am using this lens with my A300. Becos of the excellent zoom range from 18 to 250, I dont have to change the lens all the time, So I dont have to worry about the dust problem in the sensor. The images are very sharp even at 250mm. Its heavy compared to the kit lens, but not as heavy as the other lenses in this range.I think, its a must have lens for your Sony DSLR if you dont want to change ur lens all the time.
has a significant purple flare problem with internal reflections at night
I like this lens, it's very sharp even at 250mm, but you have to watch out for the purple flare. Between it and a Sony a700 it has some serious light flare at night.
