ProMaster 77mm Protection Filter - Pure Light

ProMaster SKU: 69341 | Helix SKU: PR693411

OVERVIEW

The ProMaster 77mm Pure Light filter protects your valuable lens against the elements such as sand, dirt, oil, water, and even fingerprints without sacrificing clarity or interfering with the natural light transmitted to your camera.

Thanks to a special combination of hydrophobic coatings and finely polished SchottTM B270 optical glass, Pure Light Protection filters have an extremely high light transmission rating, very low light reflectivity, and are color neutral. This equates to a pure transfer of the image to your camera’s digital sensor or film. Not only do these filters offer excellent protection for your lens against sand, dirt, oil, water, and fingerprints; but they are also easy to clean.

Each Pure Light filter has a matte black coating applied to the very edge of its glass before being carefully set into its anodized aluminum frame. This reduces the possibility of internal reflections as light passes through.

All ProMaster Pure Light filters have the same size filter thread on the front and back. So, they are compatible with your lens cap, and they can be stacked with other, same-size filters. They also come in a terrific, eco-friendly snap case. This case serves two purposes:

  1.      It provides minimalist packaging.
  2.      It acts as a storage case for your filter when not in use.

      ProMaster Pure Light filters are crafted with care and precision in Japan.

 Key Features:

  • Extremely high light transmission
  • Extremely low light reflectivity
  • Highly resistant to dirt, oil, water, and fingerprints
  • Constructed with SchottTM B270 Optical Glass which is finely polished
  • Eco-friendly packaging also serves as a storage case
  • Made in Japan

Eufy dropped the ball on this vacuum
Style: L50 SES
I’ll start by saying the reason I purchased this vacuum, is because I have a Eufy 25c robot vacuum that is very dependable. I decided I wanted an upgrade because the 25C was great for cleaning, but I had to empty it way too often. I just knew I would love the L50 SES. I thought it was just what I was looking for a self emptying robot vacuum with a 60 day fill capacity. Allowing 2 months before I needed to touch my vacuum. Here’s where things went wrong. I never got a chance to test the vacuum because it wouldn’t connect to my WiFi and I tried everything. Now this wouldn’t have been a problem if the L50 came with a remote control like the 25C. Unfortunately I had to rely on the App and since the L50 couldn’t connect to my WiFi, I couldn’t control the vacuum. The reason I gave 2 stars is because the customer service at Eufy is awesome. I was given the option to replace the vacuum with a new one but after researching the L50 i decided to return it for a refund. Apparently this model has a defect, because I found so many negative reviews about the same issue with the same model. The thing is I never read reviews because I have a Eufy smart scale, 25C robot vacuum and an Eufy security system and everything works perfectly. So in the end I purchased a Shark Matrix Self emptying robot vacuum and a Shark self emptying stick vacuum. If Shark’s vacuum preforms well, Eufy might have lost a valued customer. I hope this review helps someone make a informed decision. By the way Eufy self emptying vacuum needs replacement bags and the Shark Matrix robot vacuum doesn’t need bags. I will say the suction and design on the Eufy L50 SES was great.

Much better than the old model.
Style: L50 SES
I had an old s11 that finally died. This one is much better. It maps the house and follows a snake pattern. Once the mapping is finished you can select what rooms you want to clean. I like the self emptying feature. Plenty of battery life.

Good performance, flaky Wi-Fi connection
Style: L50 SES
The L50 physically works great - it does a good job of picking up dust and dirt at the end of the day. The pathfinder and route planning algorithm is fairly efficient at determining the best way to clean a room. Sometimes it kicks around bits of dust with its spinning brush without picking it up, but it's not often. What has been terrible, however, is the Wi-Fi support. Since our provider disabled 2.4 GHz support from their router modem without notice, I use a Mac Mini to supply the 2.4 GHz signal, and even though the Eufy is next to it and my phone gets full signal strength, it still can't connect to it half the time. After it fails to connect, it needs to be restarted or even reset to try to get the connection again. Support doesn't seem to be helpful in offering a solution.
