I love this nd and cpl filter, a 2 in 1 for the price is crazy value, i say get it. Super worth it when you have annoying reflections or when you wanna do long exposure without the super brightness

１つのパーツで何枚分かのフィルター機能を持っているのですごく便利です。使い勝手もいいし、気に入ってます。

Avevo già provato il filtro senza polarizzatore, e in alcuni contesti finiva per rovinarmi le immagini, questo invece non altera né i colori, né la qualità finale. Ovviamente le mie impressioni sono da amatore/hobbista e non da professionista, e non so se i filtri in commercio più costosi di questo hanno una resa diversa. Da tenere presente che andrebbe montato all'occorrenza, perché il cilindretto sulla ghiera esterna per regolare la polarizzazione, lo rende scomodo da riporre in borsa. Per il resto il rapporto qualità prezzo mi rende molto soddisfatto dell'acquisto.

After a few days of field use, I wanted to share some thoughts on the design, build quality, and real-world performance of this filter. While I was hopeful given the marketing claims, my experience has unfortunately been far from ideal.1. Quality Control Issues Out of the BoxMy unit arrived with excess lubricant leaking from the rotating rings. Some of this lubricant had already transferred onto the glass element, particularly on the lens-facing side. Cleaning it proved difficult - even with microfiber cloths and appropriate lens wipes, a permanent streak remains. While this might not impact image quality directly, it's a frustrating flaw, especially for a new product.2. Inconsistent Tension and Loose RotationThe tension on the rotating rings is noticeably too loose, making precise adjustment difficult - particularly when trying to fine-tune ND stops which also causes the CPL to rotate.3. Lens Hood Compatibility IssuesThe design of the adjustment knob protrudes too far, making it impossible to use a lens hood. This is a serious oversight, especially for a product meant to work with telephoto lenses where flare and contrast loss are real concerns. I experienced noticeable lens flare and reduced contrast, especially when shooting toward light sources. Yes, these issues can sometimes be minimized in post-processing, but that shouldn’t be necessary with properly designed gear.4. Color Shift Despite Marketing ClaimsOne of the more disappointing discoveries was the noticeable color shift introduced by the filter. Despite the marketing materials stating minimal color cast, images took on a warmer hue, deviating from the natural tones I get using higher-end ND or CPL filters.Final Thoughts:While I like the idea behind this filter, the execution is lacking. Between the QC issues, poor compatibility with essential accessories like a lens hood, and optical compromises like color shifting, I can’t recommend this filter in its current state at list price. I’ll most likely be returning mine and looking for another filter instead.
