Police have released this CCTV image of three men who threatened staff in a Horsham shop before stealing £10,000 worth of cameras.
The robbery took place at Jessops in Swan Walk just after 4pm on Wednesday 25 June.
Police are hoping someone may recognise the suspects and come forward with information.
All the items have unique serial numbers and police are keen to hear from anyone who may have been offered cameras or lenses in suspicious circumstances.
Detective Constable John Hord, of West Sussex CID, said:
This was a terrifying incident for staff. While no one was hurt, the men threatened to cause them serious harm. They ripped cameras and lenses from displays before making off.
We believe the three men had visited the shop earlier the same day and so we'd also like to hear from anyone who may have seen them or knows who they are.
