The CAME-7500 is the older version of what is now the CAME-7800 3-axis gimbal. The 7500 gimbal required users to build the gimbal and required tools to balance the camera on the carriage. Now, most of the gimbals that we offer are tool-less, pre-built and some even have encoders built into the motor (CAME-Single & CAME-Action). The CAME-7800 is a good gimbal for setups that might be too heavy for the CAME-Mini 2 or the CAME-Single. We have a variety of gimbal models that can hold small action cameras(CAME-Action) or bigger setups like a Blackmagic Cinema Camera(CAME-8000).
