Alex Nail, an engineer by profession, suspects thieves escaped with the kit after he had placed it outside his house as he packed his car before driving to his job in Devon.

The haul includes a Canon EOS 5D Mark II (serial number: 2931525414) and Canon 70-200mm f/4 IS lens (29592), plus a Canon 16-35mm II zoom.

Alex, who runs workshops on Dartmoor, estimates that it will cost more than £4,500 to replace the missing items which also include a Gitzo GT2541EX tripod, a set of Lee filters and a Dell U2311 monitor.

The photographer is offering a £500 reward for the return of his kit, which went missing on Friday 9 August, and has urged anyone who can help to call him on 07884 472206.

The items disappeared from Northumberland Road in Bristol.

Alex saved up to buy a secondhand DSLR in 2006, after which he quickly turned a ‘casual hobby’ into an ‘all-consuming passion’.
