it really depends on what u need.
i bought my a55 and brought it along my trip to japan.
what i could say is i am very happy using it as i am able to get alot of usable shots even as a newbie to photography.
even my wife was able to use the camera without any difficultly, which is simply amazing.
she also likes to use it to take self take shots using the live view, which was very fast and convenient.
i have taken photos out from the bullet train as well, and yes no surprise there are usable shots too, with excellent focus.
and the video is really the best in its range or even more in fact, which we used to take the fireworks at disneyland.
so overall for my family usage it was a great choice, with no regrets.
but during my time at japan, i visted the camera stores there and saw them having a fantastic range of pentax k-r.
i tell u, its a full range, no kidding here.
the camera was like rainbow colored.
not only the body has several colors to choose from
even the lens has different colors as well as the rings, dials, rubber, etc etc
it was like A TOY.
but tons of females love it, including my wife who said she wouldnt mind me buying one for her. :sweat:
