The crop ratio was probably dictated by the 28 "D" coverage.
Will Ophuis may be right about the closeness of the rear optic on the HTS, but it says "not recommended", as opposed to "Do NOT Use", which leads me to believe it is an optical quality thing. I'll have a look today ... I haven't used the HTS with the Multi-Shot camera yet, and am itching to do so.
The other aspect may be that the size/weight of the Zooms, 120 Macro, and 210 which do not have tripod collars ... so they may not be the best idea mounted to the little HTS ... that is a ton of weight hanging out there on the HTS mount.
