ProMaster 49mm Circular Polarizer - Basis

ProMaster SKU: 70400 | Helix SKU: PR704001

OVERVIEW

The ProMaster 49mm Basis filter can be used to remove or control reflections, improve contrast & saturation, or darken blue skies.

A CPL filter is a valuable creative tool. Its quality should complement your lens by handling light well and providing a clear, sharp image to the camera’s digital sensor of film. Polished optical glass, a special multi-coating formula, and high-grade polarizing film combine to achieve high light transmission and low light reflectivity. These features allow your lens to perform at its finest. Plus, any camera’s auto focus system works perfectly with a Basis CPL.

All ProMaster Basis 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.

Why use a CPL filter?

A CPL is one of the most highly used filters in both still photography and videography, and with good reason. The effects of a polarizing filter are difficult or sometimes impossible to imitate in post-production software. These effects can be used to create beautiful compositions.

A CPL can:

  1. Control reflections and/or reduce glare on non-metallic surfaces. I.E. water, glass, glossy paint, etc.
  2. Improve color saturation and contrast.
  3. Deepen/darken the blue color of skies.
  4. Reduce the appearance of atmospheric haze when photographing distant objects and landscapes.

Basis filters represent a terrific value. They are optically excellent and affordable and deliver great results!

Key Features:

  • High light transmission for a CPL
  • Low light reflectivity
  • Constructed with polished optical glass
  • An excellent filter at a value price
  • Made in China

Great case and keyboard
Color: Light Pink, Color: Light Pink
Omg. I LOVE this case and keyboard. It works so well and makes my iPad seem like a computer. It’s connects really well and I love the keyboard colors! I’ve been using it at work and it has been so great on saving notes and writing emails using the keyboard etc. And it’s very sturdy!

Made well but function is challenging
Color: Dark Cherry
I’m not so sure I really like this over all. The keys on the keyboard are nice, not mushy at all, very clear and functional. And the size of the keyboard is fine. It’s not full size and I didn’t expect it to be. But what I can’t get used to is how floppy the rest of it is. It won’t sit well in my lap, it must be on a flat surface to function at all. I find that very frustrating. The grooves that prop up the ipad won’t hold it if you move it at all. The keyboard must be unattached, moved and reattached to close up everything securely. Also it is heavier than I expected. The quality is good. It is not cheaply made. The color is just what I wanted and expected from the description. I’m giving it four stars instead of three because it is made well, but it’s mostly form over function. Edit: I returned this product and ordered a keyboard with the swivel holder for the ipad, much sturdier and steadier.

Purchased for the new iPad Pro size 11 inches
Color: Pine Green
I have a feeling that the people having issues may have the older model of iPad Pro! For the new model currently sold by Apple, the fit is good. The magnets & keyboard work perfectly. This is a great deal considering a lot of cases and keyboards cost just as much separately.

A bit disappointed
Color: Pine Green
Needed a new cover for my Ipad 11. This product had a good price, options for colors (I picked the green) and shipping was fast. When it arrived out of the box I was disappointed. Putting my Ipad 11 into the case was a bit harder than I expected. Once in, either the top or the bottom would not sat seated in the case. The backlight is nice, but you have to charge the keypad and ipad separately. I returned this because you have to physically move the keyboard to either use it or close the case or get the Ipad to stand. So, when closed the keypad sits right under the Ipad screen. When you open the case and want the ipad to stand, you have to physically slide the keyboard towards you or down to the bottom of the case. This then allows you to fold the upper portion and stand the ipad upright. You have to reverse this to actually close the case. What all this means is two things for me...this setup takes more deskstop space and a few more movements to get everything setup.

Highly recommend!
Color: Pine Green
I love the color, the feel, the weight, the functionality, all of it. The keyboard connects so easily and even has instructions on the back for enabling certain functions. I like that the mouse pad actually works, and well, and I can easily take notes as I would a laptop. I kind of want to buy another as a backup, just in case, because I love this so much! Oh, and battery life is great on the keyboard! I made it through a week long conference on a single charge.
