As with Sony’s other recent announcements, both of the cameras specs are very exciting but the most impressive and arguably the most exciting is feature on them are their sensors. The A7 and A7R both feature full-frame Exmor CMOS sensors but in a E-mount lens mount body (used by the popular NEX range) . This gives you the light gathering and detail of a full-frame sensor but in a small, light weight camera that is about the same size as the similarly styled Olympus OM-D E-M1. This will be a very exciting prospect for a lot of photographers.
The A7 features a 24 megapixel sensor and the A7r an incredible 37 megapixel sensor. The A7r has also
Obviously, as this is Sony’s first full frame E-mount compact they have had to produce a new range of lenses, they have named FE.
- Sony G 27-70mm f/3.5-5.6 OOS (only available with the A7 as kit)
- Carl Zeiss 24-70mm f/4 OOS
- Sony G 70-200mm f/4 OOS
- Carl Zeiss 35mm f/2.8
- Carl Zeiss 55mm f/1.8
Sony plan to have at least another 10 FE lens available by 2015.
FE lens are using the same E mount used by the NEX range of Sony cameras, meaning existing E mount lens will still physically fit on the A7 and A7r. However as these lenses are designed for APS-C cameras, using them on an A7 or A7r will produce vignetting, as their image circles don’t cover the entire larger sensor. This will lead to black circle around the edge of the photos which isn’t ideal. To overcome this issue Sony have given the cameras have a clever APS-C crop mode. This enables you to use E mount lens without the vignetting. If you choose this option the equivalent focal length will increase by 1.5x and the megapixel count will drop to 15 on the A7r and 10 on A7. This will however give users a much larger choice of lens until Sony bring out new FE lens in the next few years. Sony has also released a lens adapted , the LA-EA4, that will allow the A7 and A7R to utilise Sony’s entire range of A-mount lens whiles keeping AF. Also available, the LA-EA3 mount adapter allows you to connect all the A-mount lens, however does not support autofocus.
As with the QX100 and QX10 cameras released last month, Sony have continued their trend of releasing innovative and exciting cameras with a A7 and A7R What will now be interesting is to see what other manufacturers response will be, but I think it will have to be very good to complete.
The Sony A7 and A7R are expected to arrive at Park Cameras in Mid-November 2013. For further details and to place a pre-order to be one of the first in the UK to receive one of these exciting new cameras, visit www.ParkCameras.com.
