Buyers Guide

A full-frame camera is a camera that has a sensor that’s the same size as a 35mm film frame and stepping up from a camera with a smaller sensor to a full-frame model can result in better quality images. That’s because, if the pixel count is the same, each photosite on the sensor receives more light. This means that less gain needs to be applied to the signal generated by the photosites and as a result, less image noise is generated and the camera is able to capture a wider range of tones in a single photograph.

It’s this promise of better image quality that often drives photographers to upgrade from cameras with APS-C and Four Thirds type sensors.

Full-frame sensors also bring greater scope to restrict depth of field so that backgrounds can be blurred more dramatically. That’s especially attractive to portrait photographers, but it’s a useful creative tool for all sorts of photography.

Many photographers upgrading to full-frame from an APS-C or Four Thirds type camera also take the opportunity to swap from a DSLR to a mirrorless camera. There are some significant advantages to this, not least that mirrorless cameras work in live view mode full time. That means that their electronic viewfinders show the impact of the camera settings, so if the selected aperture and shutter speed combination is going to underexpose the shot, for example, you’ll see it before you press the shutter button.

Another reason that photographers who are buying their first full-frame camera tend to opt for a mirrorless model is that there aren’t that many new full-frame DSLRs. In fact, in 2020, there were only three announced, the Nikon D6 and the Canon EOS-1DX Mark III, which both cost over £6000 / $6000 each, and the more enthusiast-centric Nikon D780 which retails for around £2,199 / $2,700. That tells you something about the way that the market has switched to mirrorless photography.

The Canon EOS RP was introduced after the Canon EOS R as Canon’s second full-frame mirrorless camera. It may not have quite the same impressive specification or staggeringly good AF system as the later Canon EOS R6 and R5, but it’s still very capable and is much more affordable.

The build quality of the Canon RP is very good, in keeping with an enthusiast-level camera, but the handling is a bit more basic in some respects as you don’t have as much direct access to features as with some other models. Nevertheless, the touch control is implemented extremely well and the vari-angle screen is a major bonus for creative photography.

Those with large hands may want to invest in the EG-E1 Extension Grip to make the RP a bit more comfortable when long lenses are mounted. But it’s good to have the choice.

Combined with the compact Nikkor Z 24-50MM F/4-6.3 kit lens, the Nikon Z5 makes a very attractive camera for everyday photography and travel as, despite it’s full-frame sensor, it’s smaller than some APS-C format DSLRs.

While the maximum continuous shooting rate of 4.5fps doesn’t really impress in 2021, the Z5 still has a good 273-point phase detection AF system with Eye-detection AF for humans and pets. There’s also an excellent 5-axis image stabilisation system built-in and, of course, the Nikon Z mount which means that the Z5 is compatiblae with Nikon’s growing range of Z optics as well as F-mount lenses via the Nikon FTZ adaptor.

Despite being Nikon’s ‘entry-level’ full-frame mirrorless camera, the Z5 has dual SD card slots that are UHS-II compatible and there’s a tilting touchscreen on the back that makes using the camera intuitive.

Panasonic decided to address some of the criticisms of its S1-series of full-frame mirrorless cameras with the S5 and made it significantly smaller and more affordable. In fact, the Panasonic S5 is smaller than the Micro Four Thirds Panasonic GH5.

Panasonic also completely reworked the S5’s autofocus algorithm to make it more responsive. That work paid off, making the S5 a good choice for general photography and videography, but it’s not quite as snappy as the phase-detection AF systems in cameras like the Canon EOS R6 and Sony A7 III.

The S5 is aimed at people who have started out as photographers and content creators and who want to create more video. Its headline video specification is that it can shoot 4K (3840×2160) footage in 4:2:2 and 10-bit LongGOP H.264 at 29.97/23.98p/25p. That’s when recording internally to an SD-type card.

It can shoot at that quality and resolution for up to 30 minutes, but if you drop to 4:2:0 8-bit 4K footage, it can record indefinitely until the memory cards are full.

In summary, the Panasonic Lumix S5 is a very nice all-rounder that captures attractive stills and video.

If you’re looking for a small full-frame camera with Sony’s excellent autofocus and noise control systems then the Sony A7C is the way to go as it’s smallest of the Sony A7-series cameras. It has a flat-topped rectangular body that makes it look similar to the Sony A6600, but there’s also a vari-angle screen rather than a tilting monitor. And inside, the A7C has the same 24Mp sensor and core features as the Sony A7 III.

Paired with the FE 28-60mm f/4-5.6 kit lens., which is a small collapsible optic, the A7C makes an attractive choice for travel and everyday photography.

However, in shrinking down the A7C, Sony also made a few compromises on the handling. There’s no joystick on the back of the camera for example, and there’s only one control dial. In addition, the electronic viewfinder is the type of unit that is more commonly found in APS-C format cameras.

While it’s great to have a vari-angle screen, if you can live without it, and don’t mind a slightly larger camera, then the Sony A7 III, which sits above the A7C in the range, makes a great alternative and costs a little less.

The A7 III is the 24Mp all-rounder in the Sony A7-series of full-frame mirrorless cameras. And while it doesn’t have the revised menu structure and more extensive touch-control that was introduced with the Sony A7S III, it has an excellent AF system that makes it easy to get fast-moving subjects sharp and it can shoot at up to 10fps with continuous focusing.

Unlike the Sony A7C, the A7 III has a joystick on its back for speedy AF point selection and there are front and rear control dials for fast setting adjustments.

The A7 III can also record 4K (3840 x 2160) footage at 30p/25p with S-Log2 and S-Log3 on hand if you want more scope for grading.

There’s a tilting screen on the back of the camera, which allows you to set the AF point with a tap, and a 0.5-inch type OLED viewfinder that gives a good preview of the image as it will be captured.
