Overall Performance

The E-PL3 is overall an impressively fast and responsive camera. Autofocus is very fast, at least with static subjects, and thanks to some intelligent buffering its continuous shooting performance is pretty good as well. Meanwhile all other operations - browsing through images in playback, or navigating through the various setting screens and menus - are performed quickly and with no fuss. Fundamentally, the PEN Lite is a camera that hardly ever feels like it's getting in the way while you're using it, and that's exactly what you want.

Continuous Shooting and Buffering

The PEN Lite breaks new ground, with a maximum continuous shooting rate of 5 fps (with IS off), which takes it to the head of the class in comparison to similarly-priced models. It easily trumps the maximum shooting speed of its big brother, the E-P3. The E-PL3 offers High and Low-speed continuous shooting modes and you can define the speed for each option in the Custom C menu. As with previous PENS (and in contrast to current Panasonics) it's somewhat hamstrung for serious action work by the fact that live view isn't maintained in continuous shooting mode. Instead you get shown the picture you've just taken, which isn't very helpful when trying to track moving subjects. Live view does however return a few seconds after you take your finger off the shutter button.

The E-PL3 will shoot a series of frames at full speed in an initial burst, then once the buffer is full, slow down and shoot at a reduced frame rate. As you'd expect, larger file sizes take longer to clear from the buffer, so that shooting in Raw + JPEG produces the longest write times. On the positive side, the camera does let you continue shooting (at a reduced frame rate) while image data is being written to the card. And while you cannot review images during this period, you can access and change the vast majority of the camera's menu settings.

The table below summarizes the maximum frame rate, the number of frames that can be shot at maximum speed before the buffer is full, the reduced frame rate that follows, and the write time for all images to clear the buffer, using our fastest SD card. In all timings below, the camera was set to H drive mode.

Burst of JPEG 12MP/SuperFine images

16 GB SanDisk Extreme Pro SDHC
Frame rate 5.1 fps
Number of frames 9
Buffer full rate 1.6 fps
Write complete 4.5 sec

Burst of Raw images

16 GB SanDisk Extreme Pro SDHC
Frame rate 5.1 fps
Number of frames 9
Buffer full rate 1.2 fps
Write complete 6.8 sec

Burst of Raw plus JPEG 12MP/SuperFine images

16 GB SanDisk Extreme Pro SDHC
Frame rate 5.1 fps
Number of frames 8
Buffer full rate .6 fps
Write complete 10.7 sec

Taken as a whole, the results above are quite impressive for a camera of this class. While one could pine for a larger number of shots at max frame rate, we feel the ability to continue shooting while data is being written to the card is perhaps even more beneficial to users in most real-world situations.

Autofocus speed / accuracy

Olympus has made great claims about the E-PL3's autofocus speed, and it is indeed very fast when paired with suitable lenses (including the 14-42mm F3.5-5.6 II MSC kit lens), for static subjects at least. Its performance is on par with the best of its competitors in day-to-day shooting. And, like other cameras which employ contrast-detection autofocus using the main imaging sensor, it's essentially immune from the front- and back-focus problems which can affect DSLRs.

When activating a single autofocus location (shown in green) from one the E-PL3's 35 available focus points, the camera's AF system can quickly lock focus on a small portion of the scene. AF performance from the E-PL3 is fast and reliable for static subjects containing a reasonable amount of contrast. This 100% crop is taken from the section of the scene on which the AF system locked focus.

AS seen one the E-P3, the EPL3 includes an autofocus illuminator that addresses one of the big criticisms of previous PENs, which struggled to focus in low light. It's not a panacea - as usual it won't cover off-center subjects, its effective range is limited, and its proximity to the lens means it can be blocked by those with larger barrels - but it's a big improvement, and makes the camera much more usable in dimly-lit conditions.

Once your subject starts moving, though, things are a little less clear-cut. Contrast-detect AF systems have historically been less capable at tracking moving subjects than the phase-detection systems used in SLRs, so the E-PL3 has its work cut out to match this more-established technology. In continuous AF mode the camera's continuous frame rate drops dramatically while the camera checks focus between shots. And the lack of live view means you can't follow your subject between frames in continuous drive mode, so there's no way to ensure it stays covered by your selected AF point.

To combat this problem, the E-PL3, like its predecessor, the E-PL2, also has a subject tracking mode (C-AF+TR). Once you've designated a subject by focusing on it initially, then the camera will attempt to track it around the frame and keep it in focus, just as long as you keep the shutter half-pressed. But again, this has problems once you start shooting in continuous drive mode; naturally it only works if your subject stays within the frame (and there's no way of knowing this), and as soon as you release the shutter the camera stops tracking and resets the AF point.

All-in-all, while Olympus is certainly making some progress in this area, the E-PL3 still isn't the most practical camera for shooting moving subjects in the real world, even compared to other mirrorless cameras. For example Panasonic's implementation of continuous drive mode mode maintains live view between shots, with AF tracking that stays locked onto your subject until you reset it. Pretty well any SLR will do better too.

I bought the E-PL3 as an upgrade from my E-PL1 and took the Panasonic 20mm f1.7 lens off the old camera and put it on the E-PL3, relegating the kit lens to the E-PL1. With the f1.7 lens I seldom need a flash, but I find it easy to carry the flash in it’s little pouch in my pocket in case I need it. I don’t understand the flack about the external flash????

As I know olympus rates the battery at approximately 300 shots. The E-PL3 can also capture 5.5 frames per second in continuous mode with image stabilisation turned off. We also found that the E-PL3 slowed down to process images after about six frames shot in quick succession in continuous mode.
Are you know obout this???


Where and what is the "thumb dial" on the E-P3, that is missing on the E-PL3? I have seen this mentioned in a few other Olympus reviews, but I have not seen any dials on the PEN cameras except the single mode dial on the top.
And while on that subject, I see the PM1 is totally dial-less - has no mode dial at all, anywhere. I presume that function is covered in a menu on the LCD? I would have been satisfied with a PM1 except the mode dial seems much too handy to omit.


The "thumb dial" on the E-P3 is the dial you see.
The other dial (like on other Olympus PEN-s) is the ring over the 4-way rear controller. See the Operations and controls section:
