Either a DSLR or a mirrorless camera can be good for learning photography. The more important factors are usability and whether you’ll actually carry and use the camera often.

For learning, prioritize:

• direct external controls for changing settings quickly
• a proper viewfinder
• a fast lens if possible, so you can learn depth-of-field control

DSLRs often make learning easier because they typically have more physical controls, built-in viewfinders, and faster handling, especially in entry-level models. They also tend to perform better in low light.

Mirrorless cameras are smaller and easier to carry, which can mean you shoot more—and shooting more is one of the best ways to learn. Higher-end mirrorless models can offer plenty of control, but some entry-level models rely too much on menus or button sequences.

Sensor size also affects depth of field: larger sensors generally give you more control over background blur. Micro Four Thirds offers less subject-isolation potential than larger formats, while Sony NEX uses a larger sensor similar to many DSLRs.

Bottom line: either system can teach you well. Choose the camera with good controls and a viewfinder that you’ll enjoy carrying and using regularly.
