Corrections
If a figure here is wrong — an aperture, a focal length, a payload rating, a thread or barrel size, a transmission percentage, a price band, or a description of how something behaves — please say so. It gets checked, corrected, and the page records what changed. Nothing else you could send is worth as much, and nothing else is handled as quickly.
Questions about instruments and optics
All of it is read, and as much as can be is answered. A question that arrives repeatedly usually becomes a page, which reaches rather more people than a private reply.
Manufacturers and agencies
Specification sheets, manuals, compatibility lists and corrections from manufacturers are genuinely useful and do get used. What will not happen: coverage is not for sale, a loaned unit buys no write-up, and nothing here is sponsored. Shipping us a product reserves no position in any list, and offers along those lines are not replied to.
The address
Messages go to buissonjeanbenoit9 (at) gmail.com, an inbox read by one person, which is why an answer occasionally takes a few days.
Nothing confidential, please. This is an editorial site rather than a support desk: warranties, repairs, firmware trouble, returns and orders are matters for the seller or the maker, and there is nothing we can do about any of them here.
