OK, for those of you who would like live view on your camera's LCD, the ability for see through your lens without being behind the camera, the ability to fire based on motion detection, and in intervalometer, I have this for sale.
I bought this for my D80, but only played with it once or twice. It seems pretty useful, I just never seemed to have the time or situation where I need it. And the D3 and D300 have Live View, as well as intervalometer ability.
It will also work with several other models. Here is the list off the B&H web site, although it is not completely up to date (the D80 isn't on the list, but this works with the D80.:
If you camera has a similar viewfinder (such as the D300 being similar to the D80/D200), it will work. You can ask Aragraph for confirmation.
I have the eyepiece adapters for those, but you may need to buy the shutter release cable (Available from Aragraph, B&H or Adorama). Depending on the camera, you may also need a different eyepiece adapter, available from the same places.
In addition to the standard kit (eyepiece adapters, battery, recharger, carrying case, universal shutter release cable and manual, etc), I have a spare battery (it uses a Nikon ENEL-5), the remote transceiver cable (this lets you be up to 5 feet from the camera with the viewer, and extensions up to 33 feet are available), and Nikon D70s/D80 style shutter release cable. Additional information is available here: http://www.bhphotovideo.com/c/product/460256-REG/Zigview_S2B_Zigview_S2_Type_B_.html/BI/4775/KBID/5289/
The Zigview itself retails for $399.99, with the transceiver and release cable extra. However, I got those free on a promotion (so the box has the side with the UPC and POA removed).
I am selling the whole thing for $250, including USA shipping. I'd prefer payment via PayPal, although a check is OK (just slower for us both).
