Reach is easy to buy and hard to hold still
A telephoto narrows the field and magnifies everything, including movement, which is why the specifications that matter here are as much about holding it as about seeing with it. The focal range and the maximum aperture read as they do on any lens, with the caveat that on a long zoom the aperture at the far end is the one in use most of the time. Stabilization earns its keep here more than anywhere: the figure is in stops under a named protocol, and some lenses publish separate modes for panning, which stabilize one axis and leave the other free. A tripod collar is the part that decides whether the lens can sit on a support at all — beyond a certain weight the mount of the camera should not be carrying the lens, and the collar moves the support point to the lens' own balance. Whether it is included or sold separately is a real cost difference. Minimum focus distance is longer than most people expect and is the figure that stops a telephoto being used close. Then the practical set: filter thread, which on a large front element is an expensive size; whether the barrel extends when zooming; sealing; and the published weight and length, which decide the bag as much as the head. We compare focal range, maximum aperture, stabilization and modes, tripod collar, minimum focus, filter thread, sealing and weight.
