Pentax Optio T30 Performance

Timing and Performance

Below average speed for a consumer camera.


Power on
to first shot

3.4 seconds

Time it takes for LCD to turn on and lens to deploy.


1.8 seconds

How long it takes to retract lens.

Buffer clearing time

4 seconds
(buffer clearing after continuous LF JPEGs)

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.

Mode switching

Play to Record,
first shot

0.8 second

Time until first shot is captured.

Record to play

1.9 seconds

Time to display a large/fine file immediately after capture.

recorded image

0.6 second

Time to display a large/fine file already on the memory card.

Shutter response (Lag Time)

Full Autofocus Wide

0.96 second

Time from fully pressing shutter button to image capture, zoom lens at wide angle position.

Full Autofocus Tele

1.13 seconds

Time from fully pressing shutter button to image capture, zoom lens at telephoto position.


0.187 second

Time to capture, after half-pressing and holding shutter button.

Manual focus
0.38 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
3.88 seconds

Time per shot, averaged over 20 shots.

Single Shot mode
640x480 JPEG

3.68 seconds

Time per shot, averaged over 20 shots.

Early shutter


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

2.73 seconds (0.37 frames per second);
4 seconds to clear

Time per shot, averaged over buffer length or 20 shots, whichever came first.

Continuous mode
640x480 JPEG

1.66 seconds (0.60 frames per second);
2 second to clear

Time per shot, averaged over 20 shots.

Flash recycling

7.6 seconds

Flash at maximum output.

Download speed

Windows Computer, USB 2.0

Typical Values:
Less than 600=USB 1.1;
600-769=USB 2.0 Low;
Above 770=USB 2.0 High

*Note: Buffer clearing times measured with a Kingston Ultimate 133x SD memory card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode.

The Pentax T30's performance is generally below average. Startup time is below average at almost 3.4 seconds, though shutdown time is closer to average at 1.8 seconds. Full autofocus shutter response is below average these days, which we measured at 0.96 second at wide angle, and 1.13 seconds at telephoto. Prefocused shutter lag isn't too bad at only 0.187 second, but still slower than many. Shot-to-shot cycle times are about average, but the continuous-mode speed of 0.37 frames-per-second is well below average. The Pentax T30's flash takes about 7.6 seconds to recharge after a full-power shot - which is also below average for compact models. Connected to a computer or printer with USB 2.0, download speeds are not as fast as most other digital cameras presently out on the market. Bottom line, the Pentax T30 is one of the slower models available today.

Battery and Storage Capacity

Slightly less-than-average battery life for a lithium-ion design.

Operating Mode Number of Shots
Lithium-ion rechargeable battery
(CIPA standard)

The Pentax Optio T30 uses a custom rechargeable lithium-ion battery for power, and a charger is included. Since run times are a bit below average, we recommend picking up a spare battery and keeping it freshly charged and on-hand for long outings.

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.

(Interested readers can find an English translation of the CIPA DC-002 standards document here. (180K PDF document))

The Pentax Optio T30 stores its photos and movies on SDHC/SD/MMCcards (card not included), or in approximately 20MB of internal memory.

We strongly recommend buying a large capacity SDHC/SD memory card, at least a 1GB card, preferably a 2GB one, to give yourself extra space for extended outings and videos. (Check the shopping link above, cards are really cheap these days, so no reason to skimp.)
