The events, organised by Panasonic, will give participants the chance to attend photo walks hosted by the company’s Lumix Pro Ambassadors.
The roadshow, which runs until 23 October, kicks off on Saturday 7 May with an event at Killerton, Devon.
Panasonic says a limited number of Lumix cameras and lenses will be available for loan, including the recently announced Lumix DMC-GX80.
Participants will also have the chance to print out their photos before they leave.
The events are free for National Trust members and paying visitors to each property.
