the camera on the 1020 is phenomenal no doubt about it but it wont beat a dslr when the light goes down or in certain situations , it will still a do good job but things like , weaker xenon flash , smaller sensor then a dslr etc just mean it wont be able to keep up when the going gets tough
I love photos and I often photo parties when I go out to events , the 1020 can still get a nice picture but without variable flash and the bigger sensor the pictures I get from it aren't as alive as a dslr and things like laser trails aren't as effective
here are some pics from the 1020 I took on xmas morning ;-)
here are some from new years eve
in the shot above , the colour xenon shot of the crowd at the party you can see the 1020 was struggling , it still froze time ok and done nearly the whole room but its a flat image and the xenon flash is showing its weak output
here we have a similar shot on a micro 4/3rds Panasonic g3 which is a good camera but the sensor is smaller then a slr but bigger then the 1020 it also has a much more powerfull xenon with variable flash settings and this is what you can get from it with no edits ;-)
as you can see the g3 photos offer much more quality then the 1020s due to the hardware limitations of the 1020 ..... so while we are all loving the 1020 and how good it can be ..... lets not forget that it isn't as versatile as a slr just as the other smartphone cameras aren't as versatile as the 1020s ;-)
