Concept 2 Pm3 Bluetooth Adapter

I love the concept of this and its sister polarizing filter adapter for my R5. I do resent, however, Canon's decision only to sell each filter with its own adapter. I also believe the design of the drop-in adapter would have been better, had it allowed one to change lenses without having to first remove the adapter from the camera and other lens before first attaching it to the lens and then to the camera's lens mount.

Great concept all I needed to do was buy my adapter rings and I was set. Love Cokins affordability.

I love both the concept and execution of the Metabones Speedbooster. It works as promised- great image quality while increasing the lens speed and FOV. Autofocus and stabilization translate flawlessly. EF-S lenses do not fully cover an APS-C sensor and are unusable with this adapter. If you're on the fence about the Metabones vs Viltrox and other more affordable speed boosters, look into reviews. Yes, the less expensive versions work and boost as advertised, but the image quality you get from them- the fine details, contrast and color- all suffer from what I can tell. My only small complaint is that the image seems to be more prone to light flares. They pop up at more angles and I believe they are a byproduct of the special optics in the adapter. Hopefully if they are unavoidable, you can work them into your shots or I'd suggest using your lens' hood. I would subtract a half star for this, but opted for the 5 since you cant rate by halves. Great product!!

The Novoflex feels a lot more secure than any other adapter I've purchased. The K&F CONCEPT fits but is less snug. I really dislike play the silver mounting ring would have on the K&F. The Novoflex is locked in tight. I'm using this on my Sony FX3 and it fits great. I've also purchased the Novoflex Adapter for Contax/Yashica Lens to Sony NEX.

You may want to consider a Bluetooth adapter for your headphones rather than this. They are harder to loose and more convenient.

A brilliant concept. I love these things.

Very useful adapter for laptop w/o Bluetooth. Easy to install, and works great.

I bought this because the Sabrent USB 3.2 Type-C Tool-Free Enclosure for M.2 PCIe NVMe and SATA SSDs does not come with a USB-C to USB-A adapter, and not all of my PCs have USB-C connectors. I can say for sure that this adapter works perfectly with this enclosure. I am very happy with my purchase.

This was an inexpensive adapter and I had some reservations about ordering but eventually did. My only complaint was the way to remove the heatsink to add the m.2 drive was not intuitive and the pictorial instruction sheet was mostly useless. However, I did figure it out (why are motherboard and adapter manufacturers still using those tiny screws instead of the tool-less m.2 latch mechanisms). My Ryzen system immediately picked up the drive attached to the adapter The adapter and I was in business. The adapter and heatsink are both well-built and provide an easy way to add additional M.2 drives to your existing system.

This adapter work fine with my Intel 512GB 660P NVMe M.2 Internal SSD. Easy to install and no issues... .
