This is the new generic cable-release bracket from EagleEye Opticzooms, fitting most digital cameras (and probably plenty of 35mm compacts). In most respects this is identical to the Jessop's version.... there's not much scope for radical design in these things.
The main differences between the two are:
The new EagleEye version is devoid of plastic, the part where your cable-release screws into is metal and it's thread is unlikely to be damaged with regular use.
The section where your cable-release screws into is a far simpler affair than the Jessops model as it cannot rotate.... so the release probe is always vertical. If you knocked the Jessops version you could end up with the probe coming out at a odd angle and not tripping the shutter button. This may not be quite as good for those with slanted shutter release buttons (cp4300 and some others). All of my cable-releases fitted o.k. The main support post doesn't look as if it can turn on the base, which is good, where-as the Jessops can.... but you can tighten with an Allen key.
The EagleEye device has a slimmer build all round, so no need to get the file out to remove excess metal at the base to allow a change of batteries. The base has one long slot for adjusting how far out you want the cable-release to extend from the camera, the bolt that secures the bracket to the camera fits into this slot but is one of those designs that means it can't fall out. This bolt is quite small, has a knurled edge and has a receiving thread to allow the whole set-up to be mounted upon a tripod.
I felt that the EagleEye bracket was more secure/stable in use than the Jessops version and quicker to set-up/align. I wouldn't expect someone using the Jessops to bother purchasing this item... but it's an alternative for newcomers to digiscoping, as well as a bit easier to order for some overseas digiscopers.
