Marumi products are valued by photographers on account of good price/quality ratio. Filters with DHG symbol are equipped with improved antireflection coatings and the glass edges are blackened to avoid internal reflections.

Usage
The filter caused no troubles during the tests. It’s easily cleaned. The ring works smoothly.
Summary
1st place in the overall ranking (29.6/37.5)The transmission curve is flat within 10%. Violet color isn’t entirely extinguished, it’s not an important effect, though. The polarizer becomes transparent in infrared. The extinction coefficient of about 4/10000 is a quite good result for a foil polarizer. C1 and C2 graphs indicate that we’re dealing with a quarter-wave plate of zeroth order designed for the middle of visible spectrum. The filter compared to Marumi DHG model shows better mean transmission and lower vignetting. This parameter has probably a lot in common with used materials and/or thin layers than may work better at larger incidence angles. Even though the filter placed 1st in the overall ranking, we need to consider if, for amateur needs, it’s worth paying 100 PLN more than for ordinary Marumi DHG (4th place), if it’s only the transmission and vignetting improved, and flares remain the same. Marumi DHG Super costs 279 PLN, so noticeable less than Heliopan and B+W products, and is higher in the ranking.
The editorial staff of lenstip.com have decided to award the filter with “The choice of LensTip.com” for being the first on the list of circular polarizers’ overall ranking.
