How we test

Every piece of equipment that comes our way, whether a camera, a lens or an accessory, gets the same level of careful scrutiny. We discover what products are good at and what they are not so you don’t have to. Tests are not just made in the lab, but our technical findings are also investigated in practical situations to establish what readers can expect in real-world conditions.

With masses of experience testing equipment from every photographic brand over the last three decades, the What Digital Camera team is uniquely placed to compare all that’s on the market and deliver clear buying advice for every budget.

Editorial independence

Editorial independence means being able to give an unbiased verdict about a product or company, with the avoidance of conflicts of interest. To ensure this is possible, every member of the editorial staff follows a clear code of conduct.

Professional conduct

We also expect our journalists to follow clear ethical standards in their work. Our staff members must strive for honesty and accuracy in everything they do. We follow the IPSO Editors' code of practice to underpin these standards.
