London-based digital photography site

has been bought by Amazon in a deal showing the value of trusted reviews on niche products.

Started as a hobby site nine years ago, dpreview specialises in independent reviews of digital cameras and accessories, as well as discussions forums and buyers’ guides.

It says it has 7m unique visitors each month.

In a post on the site, founder Phil Askey said:

“One of the difficulties of operating independently has been the balance between producing content and delivering new site features.

“Now, with the support of Amazon, I’ll be able to devote more of my time to expanding and improving our features – such as product reviews and discussion forums while still delivering the high-quality content that our readers have come to expect.”

Amazon founder Jeff Bezos added:

“ is by far the most authoritative source anywhere for straight talk about new digital cameras. We at have been their fans for a long time, and we extend a big welcome to the team.”

Amazon said would continue to function as a stand-alone operation.
