![]() ![]() As you can see the electronic connections on the Pentax lens mount are on the face of the metal part of the mount. Lenses are inserted twisted clockwise and lock in place with an anticlockwise turn. ![]() The *ist DS supports a range of Pentax flash units, although the AF360FGZ as the ideal partner that will provide the maximum amount of functionality and flash to camera communication.īelow on the left you can see the *ist D's lens mount with the mirror down. The hot-shoe is normally protected by a removable plastic cover (not shown here). Flash shutter speed (X-sync) is up from the *ist D's 1/150 sec to 1/180 sec. The flash also strobes to act as an AF assist lamp in low light when up. The pop-up flash is released by button on the rear of the camera or popped up automatically depending on the camera mode. The surrounding area is perfectly flat and ideal for use with a tripod mount plate On the bottom of the camera you'll find the metal tripod socket which is aligned exactly with the center line of the lens. Mbps = Megabits per second, MBytes/sec = Megabytes per second Tripod Mount In the normal 'PC' mode it manages a very respectable 5.2 MBytes/sec which is only marginally slower than a USB 2.0 SD card reader. As you can see from the results below the *ist DS 'PC-F' mode puts the camera in 'Full-speed' (USB 1.1) speed mode which results in USB 1.1 transfer speeds. To test the *ist DS transfer speed we used a mixture of JPEG and RAW images totaling 70 MB and transferred them from a SanDisk Extreme III 1 GB SD card via four different methods. The *ist DS supports USB 2.0 Hi-Speed (maximum throughput of 480 Mbps) as well as offering backwards compatibility with USB 1.1 interfaces. Note that the *ist DS does not have a PC Sync flash terminal. Top to bottom: remote connector, combined USB (2.0 Hi-Speed) and Video Out, DC-IN. This is certainly an improvement over the *ist D (and several other digital SLR's), all of the camera's connectors are neatly tucked away behind a proper hinged (and sprung) door on the left side of the camera (from the back). We were very disappointed to discover that the *ist DS will cancel writing its buffered images if you open the SD card door, in our opinion this should be handled differently (perhaps with a warning beep until all images have been flushed). The only downside will be for those people who already have a collection of CF cards. The *ist DS becomes the first digital SLR to use only SD for storage, in reality this isn't much of a limitation as SD cards are now available in larger capacities and write performance is as good as (if not better than) Compact Flash. Inside you can see that the camera takes two CR-V3 batteries or four AA's. In the base of the camera's hand grip is the battery compartment, the door is opened by sliding a lock lever across and then pulling the door towards the front of the camera.
