Sony SLT-A99 vs Sony Alpha NEX-7
Top 16 Reasons for the
Compared to Sony Alpha NEX-7
Substantially larger sensor
23.8 x 35.8 mm
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.
Substantially higher maximum light sensitivity
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.
Sizably longer battery life
70 shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Higher pixel density
15.50% higher pixel density
Considerably faster maximum shutter speed
2x faster maximum shutter speed. A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
Noticeably higher resolution
33.30% higher resolution
8.80 mm narrower
Has a microphone in
A microphone port allows connecting external high-end or specialized microphones.
Sizably higher resolution (screen)
1229 k dots
921 k dots
308 k dots higher resolution (screen). A higher screen resolution provides a sharper image, making it easier to review your photos.
Faster photo autofocus due to a phase detection autofocus when shooting pictures
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper images.
GPS enables global positioning, useful in map, geo-tagging or navigation apps.
Has sensor shift stabilization
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.
Has an optical viewfinder
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.
Device is protected with extra seals to prevent failures due to any kind of weather.
Explicitly faster flash X-sync
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.
Has dual card slots
It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
Has Electronic view finder OLED
The viewfinder can display the effects of aperture, exposure, WB, shooting data, Graphic display, histogram
Sony SLT-A99 is better than Sony Alpha NEX-7 because...
Top Eight Reasons for the
Sony Alpha NEX-7
Compared to Sony SLT-A99
Substantially more focus points
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.
412 g lighter
Sizably better video recording quality
1080 x 60 fps
1080 x 24 fps
2.50x better video recording quality
Measurably less body volume
3.75x less body volume
80 mm shorter
35.80 mm thinner
Has a flash
A flash is good for low-light environments, and can sometimes be used as flashlight.
Adapter available for phase detection AF
If phase detection AF is important you can buy a separate lens mount adapter with it included.
