I don't really get the need for GPS on cameras. I understand what it's for but for me I'm in no hurry to geotag every picture's location.
....why can't I have built-in GPS in my D300s/D400! Now that would be cool! :)
You surprise me, Niko.
At my age, most of my photography has been pre-digital. And one of the major frustrations with film images is not knowing WHEN they were taken. Now I know precisely when every digital photo was taken. This, to me, is a huge leap forward.
A similar frustration is not knowing WHERE they were taken. Geotagging is now so easy, no more difficult than time-stamping, that I do it routinely. I don't NEED to know WHERE every photo was taken, but then again I don't NEED to know WHEN every photo was taken! The information is there if I do want it.
But I agree with you wholeheartedly that GPS should be built-in. I cannot believe that we are now well into the 21st century and it still isn't even an option on modern cameras. For example, Nikon offer a D7000 body; Nikon offer a D7000-with-kit-lens; why can't Nikon offer a D7000-GPS with built-in GPS?
(My apologies to any photography Luddites who are apoplectic at such a staggeringly radical idea!)
For the record, I now have two GPS solutions:
1) A "Foolography Unleashed" bluetooth unit linked to a "Holux M120-E" GPS logger
This is by far and away the neatest, tidiest, most discrete solution you will find. But remembering to keep the Holux unit charged (and switch it on!) is a bit of a hassle. Oh, and it's just a bit on the pricey side, too.
2) A di-GPS unit. Simple, basic, 100% reliable. I clip mine onto the camera strap where it is not too cumbersome. It has On/Off/Auto settings to control camera battery drain. Overall battery life? I've no idea. My battery (D90) seems to last forever (with or without GPS); it is so good, I often wonder why I always carry a spare.
