It's easy to fall in love with the Sigma fp miniature size and its practical industrial design. This is great to look at, considering that Sigma has always dared to be different from its camera and now there are so many different full frame mirrorless systems.
This is a camera designed to be the start of the system, but this can be controversial. Stills photographers find the Sigma fp a bit exciting to handle without the optional screw-on grip, and even then it may be ergonomically challenging.
Videographers take a different view. Here, the camera is a central component of the modular shooting “rig”, and the small size of Sigma and multiple attachment points are great advantages. After all, Sigma fp feels like an interesting alternative in the still image market, but it's a much more serious and attractive option for videographers.
