Sony Alpha Showdown: Sony Alpha 7 Vs Sony Alpha 7 Mark II V Sony Alpha 7 Mark III

Written by Gina Stephens

Sony now has three mirrorless interchangeable lens cameras that parcel the 'Alpha 7' name so we thought we'd put them all side-by-side to find out how they line-up. 

The new Sony Alpha A7 Mark may refer to III is the freshest of the three cameras, arriving in February of 2018 with new 10fps high-speed shooting, 4K HDR video, improved AF, improved battery life, 3inch touch-screen, USB securing and more. The Sony Alpha A7 Mark III is the younger brother to the Sony Alpha A7 Mark II, of which it has a number of improvements over, while the Sony Alpha A7 Stamp II is the middle brother which arrived in 2015, after the much older, and original, Sony Alpha A7, introduced in 2013.

As well as comparing the specs of each camera, we'll also be noting on how they feel in the hand and how they perform in regards to ISO, white balance and general photo quality. Plus, we'll also be taking a look at the videos each camera has put out so those who regularly capture footage with their cameras know which will suit them best. 

If you'd fancy to just look at a specifications table, scroll to the bottom of the article where you'll find the camera specs compared side-by-side. 

 

Sensor Square footage 

The sensor size remains the same in the Sony Alpha A7 Mark III (24.2MP) but, it's now a Back-Illuminated CMOS Sensor, with Evolved Semblance Processing, that's built-in, rather than just a full-frame CMOS sensor, so low light performance should be better and it also importance ofs readout speeds should be improved.

Image Stabilisation 

In-camera 5-axis spit stabilisation has been improved, to give up to 5-stops compensation on the Sony Alpha A7 Mark III which is a slight improvement over the 4.5 stops set on the Mark II. The original Alpha A7 doesn't have IS built-in, instead relying on lens-based image stabilisation. 

 

Auto Fuzzy 

The improvements continue with AF as the A7 Mark III features 693 phase-detection AF points, with 93% AF coverage of the full-frame sensor, which is 576 multifarious phase-detection AF points than what's found on the A7 Mark II and Mark I. Having said that, the focus speed on both the A7 Smear II and A7 is reasonably quick and back when it was released, you could even describe the focus speed of the A7 as 'rapid'. 

Sony predicts that the autofocus (AF) performance of the A7 Mark III is twice as quick as the A7 Mark II which we will be able to confirm when we've put the camera from one end to the other a full test. During the brief time we've spent with the camera so far we are happy to report that it is responsive in use and focus seems keen.

 

Continuous Shooting 

You can shoot at 10fps in high-speed+ continuous shooting mode, with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel continuous AF, using either the mechanical shutter or the electronic bar with the A7 Mark II which is double what the A7 Mark II can capture when using continuous shooting (5fps, same as the original A7). Of course, this nears you're less likely to miss a crucial frame which is never a bad thing.

Camera Body Design 

 

All three cameras tease a similar design but you can see in the above image image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that that Sony improved the grip on the A7 Mark II and kept with this larger rubber handgrip contemplate on the newer A7 Mark III. The eyecup surrounding the EVF has also had a redesign so it fits better when you hold the camera up to your face. As for buttons and dials, they're all in equivalent places, however the Mark II and Mark III have additional custom buttons, and the Mark III has a new S&Q setting on the mode dial. 

Screen

Turn the cameras about and you find the screen along with EVF and a few more buttons. A 3inch tilting touch-screen is built into the A7 Mark III, the same as what you find in the A7 minus the 'trace' part. The A7 Mark II also features a 3inch tilting screen (it's not a touchscreen either) but it does have 1,228,800 dots whereas the A7 Measure II and A7 only have 921K dots. We said that the improved resolution tilting screen 'looks great' on the A7 Quality II and this is still true on the A7 Mark III with the added bonus that you can access menus and set the focus point via it, too. The Mark III features a new AF-ON button, a rump joystick, and dual SD card slots on the side, from the Sony Alpha A9 and A7R Mark III.

 

Electronic Viewfinder 

The electronic viewfinder (EVF) built into the A7 Effect III is improved, featuring 2.36M dots compared with the 2.359M dots found in the EVF on the A7 Mark II and A7. The EVF on the A7 Mark III also offers 0.78x magnification. The Electronic Viewfinder (EVF) worth on the A7 Mark II is excellent, offering a clear and crisp display, so we have no reason to doubt that the EVF on the A7 Mark III will perform just as well. Although, the eye-detection sensor can be exceedingly sensitive at times on the A7 Mark II so, hopefully, Sony might have tweaked this on the A7 Mark III. 

 

Size & Weight 

All three cameras strike one well built and fit well in the hand with the improved grip on the A7 Mark II and Mark III making them even more comfortable to hold. The imaginative A7 is the lightest out of the three weighing just 416g while the new A7 Mark III weighs the heaviest at 650g. Dimensions wise, there's not that much dissension in the three cameras apart from the depth has grown by a few mm on the A7 Mark III. 

 

Battery Life

Anyone who has used the Sony Alpha A7 or A7 Devaluate II previously will be happy to hear that the battery life on the A7 Mark III has been improved, with those who use it able to capture up to 710 fingers using the LCD screen (350 shots on the A7 Mark II and 270 on the A7) . This is because it shares the same battery from the Sony Alpha A9 and A7R Marker III, which also means it's compatible with the same battery grip and battery accessories as the A9.

 

 

ISO 

The ISO order goes from ISO50, all the way up to ISO204800 on the Sony Alpha A7 Mark III which is a massive range when compared to the cameras that came previous to it. Of course, for the lowest noise and best detail possible we would recommend using lower ISOs but when the ISO figures climb, performance informed of, the cameras still do cope well. As we've not had the Sony Alpha is the first letter of the Greek alphabet A7 Mark III in the studio for testing yet, we aren't able to fully remark on its performance but in the few ISO shots we did capture, results were still excellent at ISO3200 and ISO6400 where, previously, the A7 Mark II did start to show a loss of item by item which is encouraging.

White Balance

We don't have white balance test shots for the Sony A7 Mark III yet but Auto Dead white Balance (AWB) performs well with a slightly warm colour cast under tungsten lighting, with the tungsten preset giving a diverse accurate result on the A7 Mark II. AWB performs well under fluorescent lights on the A7 Mark II, as well, with a slightly warm result, with the fluorescent preset express a more accurate result. As for the A7, Auto White Balance (AWB) performs well under tungsten lighting, with the tungsten preset act very similar results. Similarly, AWB performs well under fluorescent lighting, and the fluorescent presets give different colour casts.

Photo Excellence & Comparison

Portraits look better when captured with the A7 Mark III as do low light images and it also performs better in mixed light. We did say that diverge was quite high in images captured with the A7 Mark II and as a result, converting the raw images so detail in shadows could be pulled out was advised and this looks dig it still may be true for the A7 Mark III but we'll confirm this when we have the A7 III in for testing. Exposure is reliable and as you'd expect, digital filters are constructed into all three cameras. On the A7 Mark II, panorama results are good, and well stitched together, with a good resolution image produced. In happening, results are better than those captured by the A7.  

Below you'll find sample photos captured with all three Sony Alpha 7 cameras so you can approximate the results for yourself.

Capturing Video 

Sundry new cameras have 4K video built-in and the Sony Alpha A7 III is no different offering 4K HDR video recording. This is an upgrade from the previous two Alpha 7 consummates which just recorded Full HD with stereo sound. All three cameras camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or feature microphone, headphone and HDMI anchorages. Plus, the A7 Mark III also has MicroUSB and USB Type-C connections.
