Review Excerpt

Very small and comfortable form factor; Very good image quality for its class; New dual video record function; Quick autofocus and good dynamic range.
Lacks an EVF and external mode dial; No hot shoe; JPEG processing at higher ISOs not as good as some competing mid-level models.
Read our Sony A5100 Review

360-degree spherical panoramas at the click of a button; Puts you back in the moment like no other camera; Good ergonomics and control layout; Great still image quality, and can shoot videos too; Upload panoramas to Google Street View
Very reliant on your smartphone or tablet; Battery and storage can't be replaced or upgraded; Handheld shots suffer from Gigantic Hand Syndrome; Hard to get yourself out of the shot; Video image quality is only modest; Interval timer has a long shot delay
