Prevent hazy images caused by polarized light reflected from water, snow, glass, or water droplets in the atmosphere with the 58mm Okko Pro CPL Filter. The Pro CPL filter eliminates glare and helps you capture rich, clear shots in challenging bright conditions.

This fully adjustable filter allows you to control polarization for color saturation and greater contrast. An ultra-slim frame and glass thickness of 2mm prevents vignetting. 14 anti-reflective coatings and an optical density of 0.3 allows you to get it right in camera first.

Q: 1. Is there a recommended device that can downscale a 4k image to 1080 for this to work? I'm using it with the Blackmagic video assist which unfortunately doesn't downscale the hdmi out.

A: Regarding your question related to the Hollyland Mars 300 PRO HDMI Wireless Video Transmitter/Receiver Set (Enhanced), B&H # HOHLM300PE, if you are working with 4K signals, a 4K-compatible transmitter, such as the one that comes with the Hollyland Pyro H 4K HDMI Wireless Video Transmission System, B&H # HOPYROH, would be recommended.

Q: 2. Does it work on 5G alone or can it also work on different frequencies?

A: It will work. But I don't recommend for a live event and use it as a secondary camera because of the audio delay.

Q: 3. I bought this a bit ago and now would like to buy a dedicated receiver as well so I can have the option to use other monitors. Can you buy a 300 Pro receiver alone?

A: He is actually asking about just one to one - transmit to one receive. He, like I, just bought ONLY the SINGLE transmitter alone, but are wondering if, down the road, we can get JUST the 300 Pro Receiver Alone, just like the Transmitter was alone a single unit. The stand alone single receiver is not listed for sale anywhere.

Q: 4. Can I connect the receiver to a TV, I want to send a clean feed to a TV at a large event. Is this possible? If not what device can I use. I have a Panasonic Lumix G7

A: Yes you would be able to send the Cameras HDMI output to TV's HDMI input wirelessly using the Hollyland Mars 300 PRO HDMI Wireless Video Transmitter/Receiver Set.

Q: 5. For the 58mm version of this hood, is it possible to use a 58mm pinch type lens cap inside of it? Also, will this cause vignetting on a 17.5mm MFT lens?

A: The 58mm pinch cap works fine. Filters, though you didn't ask about them, are a related issue to consider; you can't attach a filter inside the hood. You must either use 58mm filters behind the hood, or 62mm filters in the hood's front end (either or both could create a vignetting problem). I use this hood on a 6x4.5cm film camera lens, so I can't address vignetting on your lens.

Q: 6. Does it tranmsit audio via HDMI or is only video? Im sorry im new.

A: Audio is transmitted as wel.

Q: 7. I have Mars 300 Pro and 400S. Can never get both to work at the same time. Is there a way to do it? Thanks.

A: Hi Aaron, to run multiply systems at the same time, please kindly use the channel scan feature on your 300 Pro or MARS 400S. Choose different channels for each via the Transmitter. Besides, kindly place the receivers at least 0.5m far from each other.

Q: 8. If I buy the 300 pro transmitter only.. can I run the app..an connect it too a monitor without the reciever?

A: Yes, you can purchase this and run it only to an App. It has an HDMI loop out to connect to a monitor as well.

Q: 9. What is the difference between the "Enhanced" and the " Standard" version other than the antennas being added?

A: Hi Gabriel, the external antennas on the transmitter is the only difference between the "Enhanced" and "Standard" version of Mars 300 Pro. You can choose either version depending on your application environment. Normally the "Enhanced" Version has two main advantages due to the external antenna: ① Better Performance while there is interference ② You can mount the Transmitter either horizontally or vertically since the external antenna can be bent to get the best transmission signal. While the "Standard" Version is more compact with all antennas built-in.

Q: 10. Any idea if this would work with Mamiya 6 lenses? Would it vignette the 50mm wide angle lens?

A: Sensei PRO 58mm Wide Angle Aluminum Lens Hood will fit the Mamiya 6 50mm lens perfectly. The design allow wide angle lenses to blocked light glares without vignetting.
