Jacks, Ports, Plugs (6.0)
The R1 has a USB 2.0 port and video out, and accepts an external power source for both operation and charging the battery. External flashes connect via a multi-contact hot shoe and an accessory plug, though not a standard PC sync terminal.
Direct Print Options (6.5)
The R1 supports both DPOF and PictBridge to print without a computer. DPOF creates print orders that can be downloaded to commercial printers, and PictBridge prints directly to compatible inkjet printers. The R1 can specify which images to print, how many copies to make, print size and whether to imprint the date on the image. It can also create index prints. We found the interface straightforward.
Battery (7.0)
The R1 uses a dedicated rechargeable Lithium-ion battery, which charges in the camera. The 7.2 volt, 8.5-watt-hour unit lasted quite a while in our tests. We prefer dedicated batteries, like this one, to AA cells. We find they last longer.

Memory (2.0)
The R1 has no built-in memory, but it accepts both CompactFlash and Sony's Memory Sticks. The R1 must be switched manually from one memory type to the other. CompactFlash is a standard and very broadly available memory format, and is typically less expensive than Memory Sticks.

Other Features (4.0)
Auxiliary Lenses - Sony offers absurdly large auxiliary lenses to extend the R1's reach. They add about a pound to the camera's weight, and are expensive. We have not had the opportunity to test them, but don’t see the appeal – most users interested in the R1 will likely be drawn to the camera’s fixed system.
Zebra Stripe highlight warning - The R1 takes a useful feature from video cameras and shows zebra stripes over blown-out areas of the frame, even in shooting mode. It's a useful tool for shooting in difficult light.
Automatic EVF to LCD switching - The R1 can switch the display between the LCD and the viewfinder, apparently based on whether the user's eye is darkening the viewfinder window. It's a fun idea that's well executed.
