Document: This was a great purchase! I love the release and am glad I bought this one with multiple functions. It works great and allows me unbelievable latitude in my photography!Canon TC80N3 Timer Remote Control for EOS D30, D60, D10, 1D, 1V & 20D SLR Cameras
Canon TC80N3 Timer Remote Control - I purchased this item about 2 years ago. Good product. Great Battery Life, but no manual, expensive. I wish it had some kind of case, because eventually the cord will separate (or pull out) from the body and quit working. Which it did in the middle of a photo shoot.
This remote timer does not fit the Canon EOS60D - the D60is a Nikon. However, Amazon does sell an adapter that allows it to be used with the EOS 60D  DSLRKIT Shutter Remote Terminal Convert Adapter Cable N3F-E3M. While impatiently waiting for the adapter to arrive from overseas, I ordered the Satechi WTR-C Wireless Timer Remote Shutter from Amazon at half the price of the Canon TC80N3. It has all the features of the Canon model including great quality AND IT IS WIRELESS!
I just purchased this remote for my Canon EOS 20D. Incredibly, there was no manual included. While I think that I can sort it out, I did find this website that had instructions for the manual:[...]
I bought this device to do extremely long exposures for night photography. I've paired it up with two 8x neutral density filters, and closed down my lens apertures to create "smoky" water effects. The manual took me all of ten minutes to read and helped greatly in understanding the device's operation. It's also made to work with just about all of the Canon EOS cameras I plan to work with.I'm happy I bought this item.
This timer is NOT compatible with the Canon EOS 60D camera. I bought this for my husband for Christmas and now have to return it because it does not work with the 60D. It has the connection to fit a 50D camera but when they made the 60D they changed the size and set up of the connections.
I've had my remote for over 2 years and the battery is still going strong. I'm not sure how long the battery is supposed to last, but there is an indicator in the display panel to let me know when the battery starts to get low. If the battery is fine, I don't see the indicator at all.There is a storage place on the back for your cameras RC socket cover if you have one. I use this with a Canon 20D so it is of no use to me.
I never head out for a shoot without a Canon TC-80N3 in my bag. This interval timer is so critical to my work that I have 2 of them and an extra coin battery.Pros:Your creativity will be GREATLY expanded with this combined full-featured intervalometer AND cable release. Check the PDF User Guide link for the specs on what it can do for your photography using any Canon camera (SLR/DSLR) with an N3 port.Cons:* Too pricey.
I was somewhat surprised to receive my TC80N3 with only an Canon international warranty....did anyone else receive a grey market version of this remote control? I have ordered $1000s of Canon products from Amazon.com and always received a Canon USA warranty card with the items....not sure why this item didn't carry the USA warranty.I have sent several emails to Amazon.com regarding this matter.I'll update the review when I receive an answer that is satisfactory.
My wife is into photography and we were trying to get some longer exposure shots but playing with settings on the camera itself is a hassle when you don't want to jostle the camera when it's in position on the tripod. So I got this for her and it does the trick. And a lot more besides. A little on the expensive side, but as it will work for any Canon camera that has the capability for remote control, it will be of use for long to come.
