My weye Feye device has arrived off ebay. Initial thoughts are its smaller than I expected and the verco straps are going to be useful. I've had a quick play in the house and it seems like it could be what I want for a remote method of controlling the camera. I can change aperture, shutter, iso, ev comp, wb, live view on the ipad screen (lag seems ok too), focus via the ipad touch screen, view images (including RAWS) on ipad after taking them. My only gripe would be the aperture and shutter buttons are marked as Av and Tv but I can live with that! Once I've got out a used it a bit I may write a thread on here about my experiences. I got a few ideas of images I could get using this so I'm looking forward to using it.
