Besides smartphone cameras I have a Canon SD100 w GPS and Canon 7D, but after my Canon SD100 had a warranty covered failure losing a GPS tagging camera made me think about the Canon 6D which I decided to go ahead and get. The main reasons I wanted it were the full sensor vs. an APS-C, higher noise free ISO settings (there is not a built in flash in a 6D), GPS built in, and wifi.
One of the things a full sensor makes it easier to do is blur the background to focus on a subject which the flowers in the center pop.
Higher ISO let's me crank things up. I shot this at ISO 1600, 80mm, f/7.1, 1/250. Focus isn't quite there as this was only the 2nd day with the camera. :-)
The high ISO also means the video in low light works really well. Here is a screen scrape from a video.
GPS tagging is really handy and I believed in the feature 13 years ago when we tried to tell people at Microsoft that GPS tagging of images would be big. Huhh??? was most the reaction back then.
What's the wifi good for? Wireless remote control of the camera from an iPhone or Android phone.
This is when I am so glad I am able to use MarsEdit. Writing this blog post would be totally painful in a browser app.
