Sony got into the DSLR game a little late, but boy have they made great strides to really grab a piece of the market! There is a wide variety of Sony DSLR cameras available to suit most any need, and they are all worth a look.
The DSLR-A100 was their first DSLR camera and it was very good and capable. Sony wasn't happy with 'good' so they came up with the idea behind the SLT series and their 'Translucent Mirror' technology.
