...Why so combative to all of this?
So far, I simply asked two questions: 1. Wouldn't it drain battery power? and 2. Wouldn't you need a separate unit anyway? If asking questions is combative, so be it.
I am trying to understand the attraction people have to GPS (in cameras - I highly value them in cars or phones). So far (and in my humble, subjective, selfish, arrogant, opinionated opinion -- there you go, jjj, save you the trouble), I do see some:
1. for people like Hans (i.e., workshop leaders) they might have a rather practical value -- fair enough
2. coolness factor: "Look, mom, how cool this map is, it shows all the places I visited and photographed!" - cute, but not much to do with photography
3. anal-retentive need to have, collect and preserve more and more of everything, whether we really need it or not (of which I am occasionally as guilty as the next guy)
As for maps (paper ones, I assume) you would still need to either manually transfer coordinates from the camera, or keep a separate list with it, in order to cross reference it with the map. Which then can be easier accomplished with a phone or handheld device in the first place.
I am also positing that having more and more to think of and fiddle with in a camera detracts from its basic function, i.e., to be an extension of our vision. What we need is to immerse ourselves in the subject in front of us, not the camera in-between. To that effect, the simpler the tool, the better.
Ultimately, I never denied anyone the right to have whatever bells and whistles they need or even think they need in a camera. I am just pleading for a separate model without it. Whether it is economically feasible or not is a completely different subject. As far as wishes go, I'd like to think I have the same right to
wish something, just as somebody else has the right to wish something else (like GPS in camera)
