JJC Intervalometer Timer Remote Shutter Release Time Lapse for Nikon D750 D780 Z7 Z7II Z6 Z6II Z6III Z5 P1100 D7200 D7500 D7100 D7000 D5600 D5500 D5300 D5200 D5100 D3300 D3200 D610 D600 & More Camera

Excellent product for the price (4.5 stars, rounded up to 5 stars). The device can be used as a simple (but bulky and battery powered) remote shutter release (in this case you need to set all exposure parameters on the camera and just use the big round button on the device as the "remote shutter button" for taking photos). But the main use of the device is as a programmable intervalometer where you use the small buttons below the big one to enter/set all exposure parameters on the device itself (in this case, the camera must be set to manual exposure, BULB shutter speed, and Single Shooting drive). All functions in my unit work fine! I can think of four (minor) issues with this wired JJC intervalometer: (1) The INTVL value is the time from the *start* of one exposure to the start of the next one. This means that INTVL := Exposure_Length + Gap, that is, you will need to enter the Interval value as the sum of the exposure time length and the pause/gap time between successive exposures. Thus INTVL must always be greater than the exposure length (which they call BULB). For example, if you want 15 second exposures and 3 second gap between successive exposure, enter BULB = 15 and INTVL = 18 (since 18 = 15 + 3). In some of my other intervalometers, the Interval is simply the time gap between successive exposures, which I find more convenient. (2) The camera shutter cable is hardwired into the device and is not removable. It would have been better if the device had a jack and provided a removable shutter cable for connecting to the camera. Some manufacturers do make such models, where if you are using different camera vendors/models, you can carry just one intervalometer and multiple camera specific shutter cables. (3) The printed instruction manual that came with the device is excellent (despite the small print), but the manufacturer/seller does not seem to provide an online copy of it (there are some third party online sources which provide a poorer and shorter version of the manual). So if you buy this product, it might be a good idea to scan/save the printed manual. (4) It would be really nice if the unit came with a small holding pouch with straps/velcro for attaching to a tripod leg.

This replaces an identical unit that stopped working reliably. It can be used as a wired remote single image trigger or programmed to automatically take multiple shots as part of a time-lapse series. For a time-lapse series you can program 1) the length of time before the start of the time-lapse series, 2) the exposure length of each shot in the series (although this can be set in camera, too), 3) the interval between shots in the series, 4) the total number of shots in the series, and 4) whether you want it to beep each time it does something. It does have a screen light which can be activated and is helpful during night time-lapse captures. The battery length is good and with fresh batteries you can to an overnight time-lapse with no problem. I prefer this wired intervalometer to those that use a cell phone as the dashboard because I often am using my cell phone for other functions during astrophotography. The first one of these I had lasted for several years of intermittent heavy use so I'd say the durability is good. The adapter cord that attaches to the camera is camera-specific, so you MUST get the right cord for your camera. The instructions are printed in a micro-sized font and are hard to read. There are some excellent youTube videos that cover the functionality of this unit that are worth watching. When turned off, the unit does not seem to remember the settings (although maybe I just don't know how to 'save' them.) It's a bit annoying to have to reprogram the settings each time if you are doing the same types of time-lapse series. I have this same unit for the Nikon Z8 and the Nikon Z6/D750. The only difference is the attachment to the camera.

Gets the job done, but the instructions make it harder than it should be. This JJC intervalometer works with a wide range of Canon bodies, and once it’s set, it does fire the shutter reliably. The problem is the instruction booklet—it’s pretty rough and doesn’t clearly walk you through the timing settings or how the modes interact. I had to experiment with it to figure things out, and I’m still not fully confident I’m using every feature correctly. The build quality is decent and the value is there, but expect a learning curve because the documentation isn’t much help.

Bought this to try some astrophotography. It was very easy to use with the included batteries. Plug and play with my A73. A little plasticky in the feel, and lightweight but I don't plan in beating it up. I'd say it was a great value for the price. No frills it just works.

Me has gustado demasiado el producto, es de buena calidad, fácil del programar y cumple su función. Lo recomiendo.

Fantastic product. Fantastic service...

I use this on my Fuji XT-2 for astrophotography and it works perfectly. Battery seems to last a very long time and it's quiet easy to work out all the settings once you've used it a few times. Recommended.

This is pretty cool for the price Does every thing its meant to. Looks pretty cool too.

This device does exactly what I want with the reliability of a wired connection. The quality is decent, and I appreciate the on/off switch to preserve battery life. There’s a slight learning curve at first, but it’s straightforward to use afterward. My only criticism is that it’s a bit small in the hand. I’m using it with a Sony A7RV.
