Sony SLT-A99

Compared to Sony Alpha NEX-7

anonymous
50
Significantly larger sensor
23.8 x 35.8 mm
vs
15.6 x 23.5 mm
2.32x larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
anonymous
41
Appreciably higher maximum light sensitivity
25600 ISO
vs
16000 ISO
1.60x higher maximum light sensitivity. With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.

39
Explicitly faster maximum shutter speed
0.000125 s
vs
0.00025 s
2x faster maximum shutter speed. A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.

Higher pixel density
544 ppi
vs
471 ppi
15.50% higher pixel density

Measurably higher resolution
1358x905 px
vs
1176x784 px
33.30% higher resolution

32
Explicitly faster flash X-sync
0.004 s
vs
0.00625 s
1.56x faster flash X-sync. Flash synchronization is defined as the firing of a photographic flash coinciding with the shutter admitting light to the image sensor. In general, faster flash sync speeds are better if the photographer needs to flash-fill subjects that are backlit and wants to avoid motion blur, or wants to increase depth of field by using a high aperture.

32
Has a microphone in
Yes
vs
No
A microphone port allows connecting external high-end or specialized microphones.
anonymous
31
Has GPS
Yes
vs
No
GPS enables global positioning, useful in map, geo-tagging or navigation apps.
anonymous
30
Has an optical viewfinder
Yes
vs
No
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.
anonymous
30
Faster photo autofocus due to a phase detection autofocus when shooting pictures
Yes
vs
No
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper images.
anonymous
30
Has sensor shift stabilization
Yes
vs
No
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.
anonymous
28
Weather sealed
Yes
vs
No
Device is protected with extra seals to prevent failures due to any kind of weather.
anonymous
15
Has a brand lens
Yes
vs
No
The lens is made by a reputable photographic equipment manufacturer, as opposed to a low-cost unbranded lens.
anonymous
14
A lot narrower
111.2 mm
vs
119.9 mm
8.70 mm narrower

Top Nine Reasons for the

Sony Alpha NEX-7

Compared to Sony SLT-A99

anonymous
53
Sizably more focus points
25
vs
19
6 more focus points. The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.

37
Noticeably better video recording quality
1080 x 60 fps
vs
1080 x 24 fps
2.50x better video recording quality
anonymous

Significantly lighter
400 g
vs
812 g
412 g lighter

30
Has a flash
Yes
vs
No
A flash is good for low-light environments, and can sometimes be used as flashlight.
anonymous
29
Has an electronic viewfinder
Yes
vs
No
An electronic viewfinder (or EVF) is a small display showing the image. Benefits of these over optical viewfinders include: they show more of the image, they can be more compact, focusing is easier with digital zoom, and they can also sometimes have extra info on the display, eg. a live histogram.
