Uhhhh - one says it's a motorized unit for remote control videoconferencing and educational applications, the other one (cheaper) doesn't claim any of these functions

The expensive one says it has high quality macro capability, the other one doesn't say much about it (but may be the same).

One weighs 1.45kg, the other 1.4kg

From all this I think it's safe to conclude that the lower priced unit is intended to be mounted to a camera and carried about, the other is intended to be mounted on a fixed camera and focused, etc remotely

If I had to guess (well - I AM guessing) I'd say that the two lenses are probably the same optically, but the higher priced unit has more bells and whictles and controls to adapt it to a different set of applications.

The price difference is a lot for just the remote control capabilities of the video conferencing lens - but I guess that's how it is. I can't imagine the video conferencing lens has better glass than the eng model, I think they're both in the "news quality" range.

Yes, I'd be really surprised if the lens itself isn't optically the same for both, just the added automation.

Getting some of these little motorized gadgets built can be expensive at least if you expect them to run for years and years with no failures. Also suspect that the sales volume for the conference room version might not be so enormous.

We're just in the process of getting a slightly new version of a motor developed for an application and even though we're taking an existing motor and just scaling it up a bit, the actual cost to have the motor maker modify it is well over $1million US.

Once we have it in volume production, the cost for both old and new motors will be about the same, but we need new molds for the updated version and molds are EXPENSIVE and take months to make. Motor winding equipment also needs some tweaking. Altogether, getting a motor customized for an application can be a very pricey process.

Anyhow, I'm not surprised that the motorized version is 2X the regular version.
