road les traveled said:
Sharing my humble opinion as a new user after spending 3 days with EOS 6D as follow:
1. Excellent low light shooting and image quality.
2. Low noise at high ISO up to 12800...
3. Tend to over-exposed brighter areas when the contrast within the frame are high.
4. Average auto focus for quick action shots especially shooting kids running around.
5. When using Av (Aperture Priority) mode, the shutter speed tends to bias to lower shutter speed (resulted in higher ISO; when ISO set to Auto)
6. Shutter release half press to lock focus is soft (difficult to control "half press")
7. Focus points placing seem to be too far apart, shift focus is needed to focus objects "in between". On the other hand, it's good as it seems to cover greater focus areas within the frame.
8. Excellent phase focus accuracy (stationary object) even for objects that's tiny and next to each other.
9. intermittent wifi connection with iPhone. At times, iPhone apps cannot connect to 6D thus, cannot use its remote shutter, remote viewing functions. Requires a lot of patience to wait for both the iPhone and 6D to get connected, not suitable for photo shoots in a hurry.
10. Having difficulty with the GPS connection. Either unable to connect or it takes a very long time to get connected to GPS.
11. Excellent image details when focus is locked on.
12. Noticed the slight "dark corner" on the photo when taken with 17-40mm lens. Not sure its from this ultra wide lens or from the lens hood, did not investigate further.
13. .....
There's many more observation to share and I hope to share when I find time...
14: Customization to replace depth-of-field preview button with "leveling gauge". Simple but helpful with just a press & release of the button.
15: Requiring the wifi to turn between Off and On to take video are rather troublesome.
16: Light weight is really friendly on the neck and should after carrying around for a full day.
17: Smaller camera size fit nicely with extra rooms in my existing vanguard up rise camera bag.
18: Auto Focus method during live view works well for "Quick mode" & "Live mode". During Quick mode, all 11 points work like the same AF method as the viewfinder shooting. However, it will be "black out" (interrupted momentarily) during AF.
19: Image playback on iPad work well through wifi without having to physically transfer file onto iPad is useful during shooting.
20: Switching between full auto focus points and single center focus point by pressing only one button (set button) is useful and convenient.
21: Did not find any prominent indication on lcd screen when auto focus is achieved when shooting video with live view. In addition, when subject is to near and unable to focus by a particular lens, it did not prompt user (not sure did I miss any settings). Only discover that the subject is not in focused when viewed under big screen on PC.
22: Silent mode can be easily switched by pressing/cycling through the "drive mode" . In my opinion, it's really silent, only slightly louder than the average mobile phone keypad pressing.
And some more....
