On March 21st, among general surprise, the very famous photography site DPreview announced that... in a short while it is closing after 25 years of operations.
Nobody expected this but current owner, Amazon, decided to shut down the most famous photo site on the web.
The content of DPreview should remain accessible for some time as an archive (for how long? nobody knows), but of course new gear will not be described and reviewed.
Which alternatives to DPReviews?
Well, it depends on your specific interest (forum to discuss with other photographers, reviews, tests, etc.) and your preferred language: on the web there are a lot of photography sites, though not comprehensive as DPReview has been for many photographers.
About searching cameras and lens models, LightPoint camera, lens and software database will continue to be updated with new models and links to the best reviews available on the web manually selected.
June 20th 2023 update: DPReview has been purchased by Gear Patrol, a company that deals with product suggestions with an online site a a biannual print magazine.
