At least two photographers had their gear stolen in San Francisco this weekend, victims of thieves who, in one case, didn't even have to get out of their vehicle for the crime.

The first theft of note happened at 6:35 Saturday night, on the 300 block of Texas Street (that's between 18th and 19th Streets) in Potrero Hill.

According to the San Francisco Police Department, a 23-year-old man was "standing in the street talking with friends" when a man in a newer model Audi Q6 with tinted windows "rolled by...and took the camera from [the victim's] shoulder.

The suspect never stopped and never exited the vehicle as he swiped the victim's camera and lens, police say.

Then on Sunday at 4 p.m., a 27-year-old man was "filming his friend" near the corner of Revere Avenue and Griffith Street in Hunters Point, according to the SFPD.

Suddenly, a white, 2008 model year 2 door coupe pulled up, according to the SFPD. A man aged 25-30 hopped out of the passenger seat, pointed a black handgun at the photographer's face, and demanded the camera and backpack.

The victim handed over the Panasonic camera and his backpack, and the suspect jumped back in the vehicle, which an unknown driver then piloted north on Griffith.

In both cases, police say, the suspects remain at large, and no arrests have been made. If you know anything about either theft, police ask that you call SFPD's Anonymous Tip Line at 415-575-4444 or to text a tip to TIP411 with SFPD at the beginning of the message.
