Auto Bluetooth Adapters

Not like a lot of bluetooth adapters, it work!

I have had the pleasure to sample many adapters, this unit is easily among the best. The fit and finish are top notch. I recently used the adapter with my F4s and the 80mm f/2.8 and 150 f/3.5, both performed very well and I didn't have one missed focus in a roll of print film. I will post a few samples and update my review asap. If you are looking for an adapter to use 645 glass with Nikon, you need to look no further. I am very happy with my purchase. Tip... inside the adapter you will see a small metal tab which is secured by one screw. Remove this tab if you wish to use your glass with the auto function so you can focus with the aperture wide open and simply flip the auto lever to stop for metering and your shot.

Pros: - Sound is more refined - Bluetooth 5 gives me the 8-12’ of extra distance from devices that I needed. - Connecting to the TV and iPhone at the same time is very useful. Whichever device is sending audio gets auto-selected. Better auto-connection to devices when first turned on. - Noise Cancelling is ~20-30% better with a side to side comparison. - Can be listening to TV and get a phone call from 2nd device. CONS: - Battery seems to fade faster (~10-15% faster than XM3) but probably due to the 2 added mics, extra bluetooth signal, bluetooth strength, and deeper, fuller sound quality. - Even with the new superior Bluetooth 5, some TVs (ex. 2015 Samsung LED) have continual audio glitches. (Not the headphones fault but rather a Samsung problem that may occur on other TVs as well). Love the updated XM4s and can’t wait to see the XM5s improve on the battery. Perhaps offer a second upgrade padding for we people with big heads and big ears.

The great thing about this particular model is the abilities to add Bluetooth adapters for the one friend who doesn't have streaming services or Bluetooth from their phone

So perhaps I was too quick to judge. I was having horrible battery life issues with my SL2-S and then I discovered that bluetooth was ON, which is fine, but not when Auto Wakeup is also ON. With this configuration on the SL2-S it will very quickly drain the life out of a battery even when the camera is switched off or asleep. Leaving both of these off significantly improves battery life and if Auto Wakeup is off bluetooth can remain configured ON and not drain the battery when the camera is switched off. Hope this helps others...

The adapters did exactly what we needed them to do.

I love these little adapters. It does exactly what I need it to do.

I love these and the available adapters allow you to clamp just about anything.

Very solid, so much better than using two adapters!

Like all AJA adapters, this one does exactly what it says it will.
