HP R927 Performance


Timing and Performance

Good speed for a consumer camera.

Startup/Shutdown
Power on
to first shot
2.3 seconds
Time it takes for LCD to turn on and lens to deploy
Shutdown
1.6 seconds
How long it takes to retract lens
Buffer clearing time
14 seconds
(7 seconds buffer clearing in LF JPEG)
Worst case buffer clearing time. -- This is the delay after a set of shots before you can remove the card. Some cameras won't retract their lenses and shut down until the buffer is cleared.

1.0 second
Time to display a large/fine file already on the memory card.
Shutter response (Lag Time):
Full Autofocus Wide
0.67 second
Time from fully pressing shutter button to image capture, zoom lens at wide angle position.
Full Autofocus Tele
0.61 second
Time from fully pressing shutter button to image capture, zoom lens at telephoto position.
Prefocused
0.185 second
Time to capture, after half-pressing and holding shutter button.
Manual focus
0.32 second
For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused"
Cycle time (shot to shot)
Single Shot mode
Large Fine JPEG
1.03 second ;
3 frames total;
7 seconds to clear
Time per shot, averaged over buffer length or 20 shots, whichever came first

Early shutter
penalty?
Single Shot: No
Continuous: Yes
Some cameras refuse to snap another shot if you release and press the shutter too quickly in Single Shot mode, making "No" the preferred answer
Continuous mode
Large Fine JPEG
0.64 second (1.57 frames per second);
3 frames total;

The Hewlett Packard Photosmart R927's performance is pretty good here. Start-up time is just a little sluggish, though not too terrible. Shutter lag at both wide angle and telephoto zoom settings is quite good, and "prefocus" times (half-pressing and holding down the shutter button before the final exposure) are fast as well, with a shutter delay of 0.185 second. Shot-to-shot cycle times are speedier than average, at about 1.03 seconds for large/fine JPEGs, though the camera only captures three frames at this rate. Continuous-mode speed is about average, at about 1.57 frames/second, for up to three shots in succession. Flash recycling time is about average, at six seconds. Connected to a computer, download speeds are fairly fast, so you won't feel a need for a separate card reader. Bottom line, the Photosmart R927 is responsive enough for most family photo opportunities, though its maximum burst rate in either standard shooting or continuous modes is a bit low.

Battery and Storage Capacity

Battery
Moderate battery life with the custom rechargeable lithium-ion battery pack.

Operating Mode Number of Shots
Rechargeable Li-Ion battery, CIPA spec 200
Rechargeable Li-Ion battery, Hewlett Packard spec 110-200
165 average

The HP Photosmart R927 uses a custom rechargeable Li-Ion battery pack for power, which is included along with a charger with the camera. Runtimes are moderate, so I strongly recommend picking up a spare battery and keeping it freshly charged and on-hand for extended outings. (See our battery shootout page for information on actual measured capacities of various NiMH brands and capacity markings.)

The table above shows the number of shots the camera is capable of (on either a fresh set of disposable batteries or a fully-charged rechargeable battery as appropriate), based on CIPA battery-life and/or manufacturer standard test conditions.

Storage
The Photosmart R927 accepts SD/MMC cards, though no card is included; 23MB RAM is built into the camera.

We strongly recommend buying at least a 256MB card, preferably a 512MB or 1GB, to give yourself extra space for extended outings.
