Your Lens is Only as Good as Your Filter!

Field Report:
OEC Circular Polarizing Filter

The OEC Circular Polarizing Filter, which can be purchased for between $20 and $40 (for a set, with a UV and ND filter). But are these inexpensive filters worth the price, are they cheap, or should you save your money? Let the video be a guide to whether you choose to purchase an OEC brand polarizing filter:

I really don't have much more to write about it, except that the OEC polarizer in 82mm size isn't fit for being placed on any good lens. And it'll make an average or fair lens that much worse. Here's the second part of the video, below:

The problem that I encountered was first recognized when I had to shoot a horrific fire, one of the deadliest in the history of Baltimore City. Trying to focus on the victims, I simply couldn't lock focus, even with the focus-assist box on the HVX200. It made things difficult to get a decently-sharp image from the high-resolution footage for print. At one instance, I noticed that the edges of some things in my viewfinder rotated as I tried using the CPL filter, and it turns out that the OEC filter was the sole source of the lack of sharpness in the footage. To have equipment issues that cause your image quality to suffer on something so historic is terrible; you can't take the footage and return the image quality when that happens.
