This camera is a way better performer in low light performance and noise level when comes to comparison with dslrs of other two heavy weight companies(nikon and canon). ive tested the camera performance with my friends nikon d3200 and my dads 600d and this camera survived much better and the auto focus lock technology is just awesome.
this camera performs much much faster auto focus with the kit lens when compared to other cameras in this range.
and the digital/ electronic viewfinder helped me a lot obtaining the best photo as this way what you see is what you get specially you can do all the settings with your eye on the view finder and it gonna work like you are in live view mode.
features that easily overcome canon 600d, nikon d3200 and 650d
1) much better low light performance
2) electronic view finder
3) much more color depth and dynamic range with 20 mpx
4) a in camera sensor shift image stabilization
5)great noise reduction
5)much more effects and cool things inbuilt
6)great battery back up
7)continious and faster auto focus
8)lock on auto focus
9)much light weight
10)great movie mode
only thing that is quite backward compared to those cameras is
1)a bit short screen of 2.7 inch and low pixel density compared to 3.0 inch higher pixel density
2)no battery grip available
3)lens are little costlier
so most of the people cares about photo and that definitely gives a thumbs up to slt a58k compared to those above mentioned cameras. go for this one. thank you and hit like please
