How about a Canon 700d with 18- 135 lens for outdoor mountain climbing?

1 and Canon 700D are half frames, and APS frames are multiplied by the coefficient of 1.6. The focal length of the lens is 28.8~2 16mm, and the focal length from quasi-wide angle to standard-medium focus to telephoto end is complete.

2. Although the imaging of this lens is not as good as that of the red circle head, the focal length of this lens is practical, and it can be used as a hanging head for outdoor sports photography.
