The 2 filters didn't fit the lens properly, and a scraping sound was heard as one screwed it on, or attempted to. Threads just didn't match up, or resulted in an angle that could have resulted in a damaged thread on the NIKON lens if I had continued. If you have used HOYA you know there is no sound when filter is screwed on, and it is smooth. Returns were very swift. Need better Quality Assurance in Manufacture to avoid this kind of problem! Whilst pouch is robust it would scratch the filters, that have no markings on them. Indiviual cases so much better!
Sono rimasta molto soddisfatta dei prodotti che mi sono arrivati, un set di tre lenti neutre ND con gradazione 2/ 4/ 8 + la custodia e il panno per la pulizia. Il prezzo lo ritengo molto vantaggioso rispetto ad altri prodotti simili che ho visionato (per di più senza la custodia), inoltre i tempi di consegna sono stati abbastanza celeri, pur avendo scelto una spedizione normale - standard. Ho notato che l'imballo era molto accurato per evitare eventuali danneggiamenti.
Great filters for starters and will definitely do the job. However, they feel like plastic (because of the resin composition) and theoretically they might slightly reduce the overall sharpness of the photo, although I didn't notice any (24MP sensor - Nikon D5200). The tint effect in the case of stacking them together is only natural and can be fixed in seconds within Photoshop. Personally, I combine a good CPL with the ND8 of this set and I am happy with the results (especially when I want less light to pass through (more than 3 stops down) to well capture motion and increase the depth of field (f/16-32). Overall, a value for money product for those who start playing around with ND filters and learn landscape photography, but for pro results start considering way more expensive glass ND64 or 1000 (always depending on the amount of light that you want to manipulate for the motion effect of waterfalls etc and the sharpness that you probably don't want to loose).
