The attached I posted in another Thread on WiFi Remote shooting, in it's original form (I don't remember which Thread unfortunately), I'm away on Holiday at present and this is the only version of the Original I have, but it shows what can be done with remote WiFi shooting.
I've found it a staggering omission from Canon that they haven't gone all the way with imbedded WiFi, I guess that prefer to sell a somewhat hamstrung add on in the form of the E6 at a staggering $799, this device does about 20% of what the CamRanger will do, the CamRanger sells for $299, the excuse that the Bodies of the 5DMK III & 1Dx are Magnesium & don't allow WiFi passage is patently ridiculous, others with similar Body tech have been doing it for Years.
Getting onto the subject though.
The original Image was taken with the 1Dx & 300f/2.8 II on a RRS metal low profile Tripod + RRS levelling Base, connected to a CamRanger WiFi device, which connects remotely to my iPad Mini.http://camranger.comhttp://www.reallyrightstuff.com/s.nl/it.A/id.8876/.fhttp://www.reallyrightstuff.com/s.nl/it.A/id.7819/.f
I set the tripod/Camera & attached CamRanger in the path of this Mother Leopard & her two Cubs, the Mother was extremely wary of the vehicle and we didn't want to stress either the mother or the Cubs plus there were a pack of Hyenas in the area and they've learnt that following the vehicles will often lead to other Animals Kills, and Hyenas love to Kill Leopard Cubs unfortunately (Baboons as well, Leopard Cub # 1 danger), once I set the Tripod on the path we sat off behind some bush about 50-70 metres away out of direct site, then via the iPad, remotely focussed the Animals as they got closer, then tripped the shutter via the CamRanger software on the iPad Mini once the Leopards attention was fully on the weird object in the pathway.
I've used the CamRanger now extensively, the app you download to control the gear via the iPad (or phone, computer etc) is remarkably good, allows setting of most Camera Functions including focus with an AF lens, it's best to set a wider aperture as although the equipment reacts quite fast, it doesn't allow for constant AF of a moving subject as far as I've been able to test to date.
I've also just purchased the CamRanger MP360 Motorised Tripod Base and I'm quite impressed with this piece of equipment as well.
Only downside I've found to date is that Lions are not only inquisitive, but they also like to "taste" the gear, so be prepared and bring an extra Camera.
