We can find they have similar weight and same size display, But there are some difference between the A77 and 7D, Which is better to buy, Read now!
Screen and Battery
There is no need to talk about the design as we showed the reviews above, The more important thing is the feature and performance.
Both of Sony A77 and Canon 7D shared the 3.0 inch LCD monitor Which has 921k dots of resolution, The sharpness is excellent is no need to worry, But the screen in Sony SLT A77 is a tilting screen, But the Canon 7D’s is fixed. The titling maybe extend the size but helpful for shooting any angle scenes, I think i like the it.
The Canon 7D won the battery comparison by the 850 shots on fully recharged battery which is much higher than 510 shots in Sony A77. If you like taking photos outside, The Canon EOS 7D is better to use.
How about the Performance?
If you prefer to the continuous shooting speed, You will like the Sony A77 which has the speed of 12 frame per second faster than 8fps of Canon 7D.
Not only the continuous shooting speed, But The 24 MP APS-C 23.5×15.6mm CMOS Sensor is also lager than 7D’s 17.9 MP CMOS Sensor. The advantage is showing up first in image quality, even though the Canon 7D comes with the high sensitivity performance, But the Sony A77 seems a little better, The level of noise reduction of two camera has a bit gap too.
There is no big difference between the video quality of Sony Alpha A77 and Canon EOS 7D, Because they all had the 1080P video mode, Maybe the A77 is good at video shooting with the 60 fps frame rate, But the Canon 7D is only has 30fps of frame rate.
Conclusion Of this Comparison
I think the winner is clearly, Sony A77 is better than Canon 7D in almost all features except the battery life and Price, As we know the price of Canon 7D is $400 lower than Sony A77.
