This time Sony DSLR back out the middle class. Stay with the 14MP CMOS sensor and the ability of AF Life View  System, the Alpha 450 feels like his elder brother a few time ago appeared, namely the Alpha 550. So you can take advantage of more photo opportunities, and see your subjects come alive with the supernatural realism of Auto HDR in-camera high dynamic range imaging.

5. SteadyShot INSIDE™ image stabilization – another powerful ally for low-light shooting.
6. Capture images of amazing beauty and supernatural realism with Auto HDR.
7. D-Range Optimizer for naturally balanced exposures in virtually any shooting situation.
8. Creative Style settings – the easy way to make your artistic dreams come true.
