The Phottix TR-90 Multi-Function remote (PH18320) provides a simple trigger function and can activate the bulb function on Nikon N8 cameras. It provides such functions as a self-timer, interval timer, long-exposure timer, exposure count setting feature. It is a good replacement for Nikon MC-36.
Just received the TR-90 for my Canon 5D Mark IIs. It's unusable. The connector doesn't have a threading screw to tighten into the camera body. The unit's female connector simply fits onto the camera's three pins and falls off. Just seeing how it works at my desk, the thing falls off. Without a screwing mechanism, this is useless.
Easy to use, so far not one mishap.
I use this product for astronomy imaging with a Canon 20DA. I take multi images of the same object for up to 3 to 4 hours. Hands free operations. I also own their other remotes for the Fuji IS Pro and for the Canon T3i.
The only reason I didnt give this item 5 stars is because the directional controls are a little cumbersome. The Canon version has an actual button to switch between modes. Other than that, it works just fine. No other reason to buy the Canon one.
I've had a similar unit before for another body and the lack of a power switch was annoying always having to take the batteries out between uses, this model now includes a power switch which helps no end, and the functionality of the unit is great for time lapse shots, bulb exposures, and other landscape shots with longer shutter speeds where you don't want to be touching/bumping the camera while shooting... also handy to use in cold weather for remote release off a tripod while wearing gloves.
Great product, easy to use. 1 page user-manual which was easy to understand and was quickly able to learn to use it.
There are two photographers in the house and we both like to make long exposure photos. We have been sharing a Nikon intervalometer, MC-36, and we have had too many conflicts around who was going to get to use it. We needed another one but did not want to pay the price of another Nikon unit. The Phottix TR-90 is perfect for what we want. Its controls are identical to the Nikon so it does not matter who gets which unit. Works great!
I used this product for multi-images for the 2012 Venus Transit, and also for long multi-images in astronomy.
I was looking for something that was comparable to the Canon C8, but didnt want to spend more money than needed. Found the Phottix version, and am happy to say it has met all my expectations. Has all the features of the canon TC-80 at around half the price.
