Hii.. i want to buy a camera my 1st one. I loved two cameras
1-sony a58 (mirrorless)
2-sony hx400v(P&S)
I just wanted which out of this is capable of taking detail, good quality images. Please help.
Between the two you listed, the Sony a58 can give much better results. Put a decent lens on it, learn how to use it (use good technique) and you will be very pleased with the results.
The sony hx400v is called a bridge camera. It offers a large zoom range which means not a very good lens and it has a very small sensor which also limits the quality.
The Sony a58 is not really a mirrorless. It has a mirror, but it is mostly clear. This is called an SLT. Look at Sony A-mount lenses to use on it.
Since you prefer Sony, also consider the Sony e6300. It is not a SLR looking body (like the two you mentioned), but it has a newer sensor and is getting more of the newest lenses from Sony. This one uses E-mount lenses/
