The Buyers guide to...Which cameras have the highest fps in burst mode?

• Burst Mode (electronic shutter): 20fps with C-AF
• Burst Mode (electronic shutter): 60fps with S-AF
• Burst Mode (mechanical shutter): 9fps with C-AF
• Burst Mode (mechanical shutter): 12fps with S-AF

We’ve seen an escalation in continuous shooting rates recently with electronic shutters also allowing silent shooting. When the electronic shutter is in use, the G9 can shoot at up to 20fps (frames per second) with continuous autofocusing (AFC), that puts it level with the full-frame Sony A9. That’s good news for wildlife photographers who don’t want a clicking shutter to disturb their prey.

If you want to shoot faster still, the G9 can shoot full-resolution images at an incredible 60fps in single-AF mode, that is, with the focus set at the start of the sequence. That’s good news for shooting static action like water splashes or fleeting facial expressions.

At full-pelt, the G9’s buffer enables up to 50 raw files to be captured. If you switch to use the mechanical shutter, the maximum shooting rates drop to 9fps with AFC and 12fps with AFS, but the burst depth expands to 60 raw files.

In addition, Panasonic’s 4K Photo and 6K Photo modes are on hand with their convenient modes to help with capturing brief bursts of action. These modes use video technology to capture sequences of images which can then be extracted to create 8Mp (4K) or 18Mp (6K) still images.

The G9 can shoot 6K Photo images at 30fps for up to 10minutes. Alternatively, 4K Photo mode can be used at 60fps for 10 minutes or 30fps for a maximum of 30 minutes. Shooting for 10 minutes at 60fps produces a lot of 8Mp images!

The OM-D E-M1X uses Olympus’s Pro Capture mode for shooting stills of very fast action. Thanks to the dual processors, there’s no blackout in the viewfinder when this is in action.

In Pro Capture High mode, the shooting rate is 60fps, but the focusing is fixed at the start of the sequence. Switch to Pro Capture Low, and you can shoot at 18fps with continuous focusing.

Pro Capture mode is designed to help you record fleeting moments that are easily missed. To that end, when it’s activated the camera starts writing images to the buffer as soon as the shutter release is half-pressed. Once the shutter button is pressed fully, the 35 images that were buffered immediately before it was pressed are recorded along with 100 from immediately after.

There’s also a standard sequential shooting mode that uses the mechanical shutter. When this is in action, the maximum shooting rate in single AF mode is 15fps for 143 raw files. In continuous autofocus mode, the maximum is 10fps for 283 raw files.

A High Res Shot mode also delivers larger and more detailed images. The 50Mp Handheld mode captures the images quickly but then takes a little longer to render the final shot than the Tripod mode. Comparing the results with standard images reveals a nice jump in the level of detail.

Similarly, the 80Mp tripod mode delivers impressive results. It gives a significant boost to the size of print that you can make. That compositing also has a beneficial effect on the dynamic range as there’s more detail visible (and extractable) from the shadows.

• Burst Mode in C-AF: 20fps
• Raw Files at 20fps: 241
• JPEG Files at 20fps: 362

The Sony A9’s 24.2-megapixel full-frame sensor’s integral memory works in tandem with the Bionz X processor to enable faster data readout. As a consequence the Sony A9 has a full resolution maximum continuous shooting rate of 20fps (frames per second), that’s with continuous autofocus and metering.

That blistering pace can be maintained for up to 241 raw files or 362 jpegs – equating to roughly 12 seconds shooting continuously in raw format or 18 seconds in jpeg format.

So you should able to capture every fleeting expression on a top-class 100m sprinter’s face from the gun firing to the finish line and still have some capacity for the winner’s celebration.

In continuous AF mode the A9 is quick to latch onto moving subjects and it follows them with apparent ease. Angela, our reviews editor, normally shies away from settings that give a camera free rein to determine the AF point to use, but the A9 performed superbly in Wide AF mode even when there was a cluttered background such as cliffs or rocks behind the moving birds.

When she was using continuous AF mode to photograph my dog on the beach, She noticed that if he was still the camera sometimes focused on a point a little closer to her than he was, but as soon as he started moving it snapped onto him. If he ran towards her his head got the AF system’s attention; if he ran away it was his backside.

During our testing, the D5’s autofocus system put in an excellent performance, getting subjects sharp quickly and keeping moving subjects in focus as they shifted position, even in gloomy lighting.

Interestingly, when the continuous autofocus priority in custom menu a1 was set to Focus rather than release the camera became very hesitant in low light dropping the shooting rate dramatically.

However, when it was switched back to the default of Release the vast majority of the shots taken at 12fps were sharp. Clearly it doubts itself a bit more than it should.

As usual, the highest hit rates are achieved by narrowing down the AF point coverage with single AF point often proving to be the best option provided the subject is a suitable size and you can keep the selected point in the right place.

We found 25-point dynamic area AF mode to be one of the most useful options giving a good balance between AF point coverage and ease of keeping a point over a fast moving subject.

• High-Speed Continuous Shooting Mode: 7fps
• Low-Speed Continuous Shooting Mode: 3fps
• Silent Continuous Shooting: Mirror raised slowly for less noise

While the 5D Mark III offered 22.3 million effective pixels, the Mark IV has 30.4 million, marking a significant jump up in resolution.

However, the inclusion of Digic 6+ processing technology enabled Canon to push the Mark IV’s native sensitivity range up from ISO 100-25,600 to ISO 100-32,000, with expansion settings taking this to ISO 50-102,400 – the same as the 5D Mark III. In video mode sensitivity can be set in the range ISO 100-102,400.

Interestingly, the Canon EOS 5D IV has a dual processor, as the Digic 6+ unit is accompanied by a Digic 6 processor. The Digic 6 processor takes care of the exposure metering while the Digic 6+ engine takes care of image capture and processing.

It enables a maximum continuous shooting rate of 7fps (frames per second) with continuous autofocus and metering for up to 21 raw files or an unlimited number of jpegs. In live view mode the camera can shoot at up to 4.3fps.

Canon hasn’t given the 5D Mark IV more autofocus points than the 5D Mark III but the 61 points are spread further up and down the frame. Also as before, there are 41 cross-type points; however, 21 of them are cross type down to f/8 (rather than f/4).

There are also 5 dual cross-type points that are sensitive down to f/8 (with the 5D Mark III these are dual cross-type at f/2.8). The system also operates down to -3EV, 1EV darker conditions than the 5D Mark III’s system. This all adds up to make the Canon 5D Mark IV’s autofocus system more sensitive and better able to detect a subject.
