Olympus E-520 Performance


Timing and Performance

The E-520's timing performance was similar to the E-420, ranging from below average to slightly above average speed for a consumer SLR.

Startup/Shutdown
Power on
to first shot
1.4 seconds
Time it takes for camera to turn on and take a shot.
Shutdown
0.7 second
How long it takes to turn off.
(Timings with 266x CF Card)
Buffer clearing time
Large Super Fine JPEG
4.5 seconds
(after 12 LSF 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 shut down until the buffer is cleared. (*See note about memory card speeds at bottom of cycle time table below.)
Buffer clearing time
Small Basic JPEG
0.5 second
(after 20 SB JPEGs)
Buffer clearing time
RAW
5 seconds
(after 9 RAW frames)
Buffer clearing time
RAW + LSF JPEG
11 seconds
(after 6 RAW + LSF JPEG frames)

Startup time was a bit slow for an SLR, due in part to the ultrasonic sensor cleaning that takes place each power-up. Shutdown was also a bit slow for an SLR. Buffer clearing time depends on the image size and quality, burst length and the speed of memory card used.

 

Mode Switching
Play to Record,
first shot
0.3 second
Time until first shot is captured.
Record to Play
1.4 seconds
Time to display a large/super fine file immediately after capture.
Display
recorded image
0.7 second
Time to display a large/super fine file already on the memory card.

Mode switching is reasonably fast, except for Record to Play, which is slower than average.

Hybrid Mode
0.551 second
Time to capture from fully pressing shutter, using Live View mode. Prefocused with AEL/AFL button.
Continuous AF
Optical Viewfinder
0.175 second
This mode usually shows no speed increase with our static subject; we have no way to measure performance with moving subjects.
Manual focus
Optical Viewfinder
0.115 second
For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused".

Very similar results to the E-420 here. In terms of the E-520's ability to determine that it's properly focused when shooting the same target multiple times, its speed is above average for a consumer model when using the optical viewfinder. The E-520 measured 0.130 to 0.135 second for full AF shutter lag, depending on the zoom position. Continuous autofocus mode lag time was a bit slower at 0.175 second, and manual focus was slightly faster at about 0.115 second. When prefocused, shutter lag dropped to 0.080 second.

Autofocus performance drops considerably in Live View mode however. Full AF shutter lag in the default "Imager AF" (contrast-detect) mode is a whopping 2.548 seconds, much longer than even the slowest point & shoot digicam these days. Switching to "AF Sensor" (phase-detect) mode and holding down the AEL/AFL button while fully depressing the shutter release improved lag to 0.718 second, which is still quite slow for an SLR. Lag with "Hybrid AF" mode, which uses a combination of contrast-detect and phase-detect AF was 1.256 second, still very slow. Even prefocused, Live View shutter lag is a relatively pokey 0.55 second, independent of mode.

 

Cycle Time (shot to shot)
Single Shot mode
Large Super Fine JPEG
0.51 second
Time per shot, averaged over 20 shots, 3.5 seconds to clear.
Single Shot mode
Small Basic JPEG
0.51 second
Time per shot, averaged over 20 shots, 0.5 second to clear.
Single Shot mode
RAW
0.51 second
Time per shot, averaged over 14 shots, 5 seconds to clear.
Single Shot mode
RAW + LSF JPEG
0.50 second
Time per shot, averaged over 6 shots, 11 seconds to clear.
Early shutter
penalty?
No
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 Super Fine JPEG
0.28 second
(3.54 frames/sec);
12 frames total;
4.5 seconds to clear
Time per shot, averaged over 12 shots. Then slows to about 0.47 seconds per frame or 2.13 fps.
Continuous mode
Small Basic JPEG
0.29 second
(3.48 frames/sec);
20+ frames total;
0.5 second to clear
Time per shot, averaged over 20 shots.
Continuous mode
RAW
0.29 second
(3.45 frames/sec);
9 frames total;
5 seconds to clear
Time per shot, averaged over 9 shots. Then slows to about 0.75 seconds or 1.34 fps.
Continuous mode
RAW+ LSF JPEG
0.29 seconds
(3.47 frames/sec);
6 frames total;
11 seconds to clear
Time per shot, averaged over 6 shots. Then slows to about 1.63 seconds or 0.61 fps.
Flash recycling
3.4 seconds
Flash at maximum output.
*Note: Buffer clearing times measured with a Kingston 266x Ultimate CompactFlash card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. Settings such as ISO sensitivity can also affect cycle times and burst mode performance, with higher ISOs generally increasing JPEG cycle times and reducing burst performance.

Again, very similar results to the E-420. Single-shot cycle time performance is about average for a consumer SLR, at about 0.5 second between shots in any quality mode. Buffer depth is quite good though, at over 20 JPEG frames or 14 RAW frames. Continuous mode is about average at about 3.5 frames per second, but buffer depth was quite good for an entry level SLR, at 12 large/super fine JPEGs or 9 RAW files. Flash recycling after a full power shot is 3.4 seconds, which is fairly quick.

 

Download Speed
Windows Computer, USB 2.0
5,606 KBytes/sec
Typical Values:
Less than 600=USB 1.1;
600-770=USB 2.0 Low;
More than 770=USB 2.0 High

Download speeds were also quite fast, fast enough that you probably won't feel the need for a separate card reader.


Bottom line, the Olympus E-520 is generally a very responsive camera, able to handle average family shots as well as some faster action. A very good performance for its class.

Battery and Storage Capacity

Battery

Above average battery life when using the optical viewfinder.

Test Conditions
Number of Shots
Lithium-ion rechargeable battery,
(CIPA standard)
650
Lithium-ion rechargeable battery,
Live View
unknown

The Olympus E-520 uses a custom rechargeable lithium-ion battery pack for power, and comes with both a single battery and charger. The rated 650 shots per charge using the optical viewfinder is above average for an SLR. Olympus doesn't publish battery life for Live View mode, but you can expect it to be lower, so we recommend getting a second battery.

The table above shows the number of shots the camera is capable of on fully-charged battery, based on CIPA battery-life and/or manufacturer standard test conditions.

Storage
The Olympus E-520 stores its photos on Compact Flash and/or xD memory cards, and no card is included with the camera. The table below shows average file size and capacity figures, as well as approximate compression ratios.

The Olympus E-520's images are pretty large. We strongly recommend buying a large capacity Compact Flash or xD-Picture card, at least a 2GB one, preferably a 4 or 8GB one, to give yourself extra space for extended outings. (Check the shopping link above, cards are really cheap these days, so no reason to skimp.)
