Summary: A great accessory
Comment: Canon's remote shutter release cable is very well built and performs beautifully. A must have if you are going to be taking any shots using a slow shutter speed. The button is responsive and the tactile feedback makes it easy to differentiate between autofocus and shutter release. It even has grooved sides and a notch on top and bottom to securely wrap the cable and is topped off with a hole to insert the plug for nice tidy storage. Don't think about it, just buy it!

Summary: An essential piece of equipment
Comment: Although I managed for a time with the delayed shutter release option when using my 400D on a tripod, the 10 second delay between pressing the shutter and the taking of the picture frequently meant the scene had changed. So I went for the obvious, a cable release or remoter switch. As I do a lot of close-up photography working behind the camera this seemed the better option over a wireless remote which operates from the front
With a very positive action it is easier to control the dual operation than using the camera's own button. In fact I use whenever there is the likelihood of camera shake, and not just when using the camera with a tripod; hand held telephoto shots or close-up shots, or when selecting a slow shutter speed it is invaluable as one can press the shutter realise with no fear of moving the camera.

Summary: Cable Release for Nikon D-300 w GeoPic II tagger
Comment: I bought this cable release to use with my Nikon D300 and the
Custom Idea GeoPic II - Direct Connect Geotagging GPS Unit for Nikon & Fujifilm Digital SLRs. The Geo Tracker plugs directly into the 10 pin connector of the Nikon - which blocks using the normal Nikon cable release. However, the GeoPic has a connection to add the Canon or compatible cable release. The combo works great together.

Summary: Great device for a cheap price.
Comment: This remote is great. When I first got it, just testing it out makes my life easier for photography. It's much more easier than pressing the shutter button and causing even more shake. Simply, it works the way it was made. Some reviewers have given this item a low rating because they figured it was intended for self portraits, etc and the cable was not long enough (cable is around 1 1/2'). I don't believe this switch was intended for that but whatever. I'll primarily be using this for macro photography and astro photography and this is a major help to that. This shutter release also has a locked position so you can relax while the shutter is opened for longer periods (astro photography). Very cheap and very handy (although it seems Amazon has raised the price only a couple days after I bought it. $17 to $24?). Only con? Mistook the size. Smaller than envisioned. That's about it. Buy this if you're deep into photography and you won't regret it.
