Q: 1. Is this modem the CM1000 or CM1000 v2? I thought it's v2 but Mine version number is 6.01.02. It's CM1000, not the v2 as some people mentioned in their reviews.

A: It's possible our inventory is mixed with different revisions of the same product. Sorry for the inconvenience. Manufacturers do not update the product model number's when new revisions come out and we are not able to tell which version it is. I apologize for the inconvenience.

Q: 3. Does this product work with MacOS?

A: Yes, the Sabrent M.2 & 2.5" / 3.5" Drive USB-C 3.2 Gen 2 Docking Station is compatible with Windows & macOS.

Q: 4. Does the ECC require any functionality from the host motherboard?

A: Not all motherboards are made to support ECC RAM. However, ECC RAM will work in a non-ECC motherboard… as long as it is unbuffered. If the CPU or motherboard doesn't support ECC, the board will recognize it as non-ECC RAM and continue to work as normal.

Q: 5. Can I use this Canon 135mm lens on my Sony a7rii body ? What is the best lens adapter/converter to use with it,, that will relay info and not degrade picture quality?

A: The ZEISS Milvus ZE lenses were designed for cameras using the EF mount. The lens can be adapted to cameras with a shorter flange focal distance via 3rd party adapters. These do nothing more than position the lens to the proper distance from the sensor so the lens focuses at infinity. There is no degradation in image quality when using adapters of this type, since there are no additional optics involved. Since the Milvus ZE lens uses and electronic aperture, you will need a 3rd party adapter that allows control of the aperture via the camera body.

Q: 6. Will this work on the Asus Rog Zenith II Extreme Alpha?

A: Yes, this will work on the motherboard. There are 4 PCIe 4.0 x16.

Q: 7. What would be a better option for portraiture, This Lense of the canon 35mm 1.4 ii? (Ps I already own a 85mm)

A: When used with a full-frame camera, a 35mm focal length is a modest wide-angle lens and is well suited for environmental or group portraits. When the same lens is used on a camera with an APS-C sensor, then it behaves like a 'normal' focal length and is suited for head-and-shoulder portraits.

Q: 8. When used on A7Rii with adapter, does it provide focus confirmation? Thanks

A: I'm using my Zeiss manual focus lenses on an a7R iii and find the focus peaking assist on the camera indispensable to sharp, sharp...sharp images!

Q: 9. I want use it for optimum online in New Jersey, this is compatible?

A: Yes, this item would be compatible with optimum online New Jersey for internet services only.

[2"] My old HDMI cable has been dying for a while, requiring me to hot plug it several times to get it running. This cable is great, totally solid performance. It's such a relief. Also the guys at B&H were incredibly helpful in finding the exact one I needed.

[2"] For long raw HDMI connections, C2G quality is tops. Would not hesitate getting C2G for even longer cable connections to recorders.

[f/2] They work quite well; no halos or any undesirable behavior which I could notice as of now. They did require an increase in exposure time, but that's expected.

[f/2] Love this cable!! I can do 4K 120p RAW video to the Atomos with this.

I do however wish there was also a version with 90 degree angle ends. I would buy one in a heartbeat.
