7D Compatability

[GoogleCodeExporter]

Currently no functioning hardware so I can't be as specific as I should be with 
this but I thought I would put my observations with regards to 7D compatibility 
out there. I haven't had a close look at the software at either end yet so 
these are just general observations.

Shutter speed
-There is a point at which shutter speeds do not match, from memory speeds 
longer than somewhere around the 1" mark become 1 step out of sync.
-Below this point things work as expected.

Iso
-Iso range is much wider on a 7D, up to 6400 so there is a bunch of iso values 
that cant be selected.

Live view
-Activating live view does not activate the display on the camera.
-Moving focus seems to work but only 4 or 5 steps across the whole range.
-Trying to capture with live view activated results in a complete freeze of the 
camera, need to remove the battery to bring it back to life.
-from what I understand the live view system changed quite a bit with the 7D 
(or it might have been at the 5D mkII) so I will have to do some investigation 
on this front, I suspect this may be the cause of these problems.

Anyhoo, once I have my 2nd iteration of the controller sorted I can make more 
specific checks.

As a side note check the baud rate of your BT module if your having problems. I 
thought I had changed it and couldn't figure out what I had wrong. It finally 
occurred to me to get the module to tell me what it was actually operating at 
and the change hadn't been affected at all.

All the issues you mentioned applies for the 550D too. I only recently found 
out about those issues. 

I will get them fixed in the next iteration. 

The ISO range will also be expanded and so will the "live view on camera" 
issue. (In fact, it was actually designed to display the live view on the 
EXTERNAL monitor connector, which worked on the 1000D that I used to develop 
the controller.)

On the focus control, this feature was included as a proof-of-concept rather 
than a something of practical utility. [side note: the follow focus that is in 
the works for this project will be pretty interesting. Think 'Okki Follow 
focus'.].

But still, I will include smaller/larger focus steps in the next iteration. 
(EOS utility style) 

A more serious issue you mentioned is about the camera freezing. I am having 
this too on the 550D and I will start looking into this ASAP.

Expect the next iteration of the Android App within 2 weeks. 

Thanks for the feedback.
