A bunch of us were in the Birmingham branch yesterday getting trained up on the 1DMkIII and WFT-E2 wireless transmitter.
The first thing we all addressed was the now infamous focusing issue.
My opinion now is this...
1. There is an issue with high contrast subjects (you might read this as sunny conditions), this is being fixed in firmware.
2. There are way too many customisation options for most photographers to deal with. This is especially true of the focussing system where it can be very easy to completely screw it up buy setting it up wrong.
So, we were happy with the conclusion that a good read of the manual and a flash of the firmware would sort everybody out.
The best part of the day by far came when we plugged in the WFT-E2 wireless transmitter. If you never had the pleasure of using the first version of this (the WFT-E1 strangely) you'll know it was an absolute dog to get working. I'm glad to report that Canon have definitely learnt from their mistakes. The new one has a short setup wizard (accessed on the camera's screen) that works like a dream. It shows you all the available networks, you pick one, enter a password (if needed) and you're up!
The system has two ways of working; PTP and http.
PTP works in conjunction with the new DPP (Digital Photo Pro) software and allows complete wireless control of every aspect of the camera, including manual focus adjustment, exposure and firing, you even get a live view through the camera courtesy of the cameras live video.
HTTP basically gives you a webserver running on the WFT-E2 so you can access it using any computer on the same network just by typing the cameras IP address into a web browser. Http access doesn't give you total control over the camera however, you can fire it ans see/download the resulting image and you can browse any storage the camera is using (SD card, CF Card or USB drive connected to the WFT-E2). However, there's nothing to stop you using port forwarding on your router to make the camera accessible from the internet.
This is the screen for firing the camera:
And this is the browser window:

The possibilities with this combo seem endless, I can't wait till we've got enough stock (read no back orders) to get some in rental.
Have you used the 1DMkIII? What did you think? What uses can you think of for the WFT-E2?
