I like the low weight of the Ditzco, but I have already scratched up one of the filters. He gives you 3 of each one, but I was hoping they would last longer. I have emailed David Ditzler about ordering replacements, but he never responded.hi, what filters did you end buying? im deciding between Ditzco ( because they scratch easier than a glass filter, and can't see in the web page replacements just for the plastic sheet) and fotodiox https://www.amazon.com/gp/product/B01G9HCYTW/ref=ox_sc_act_title_4?smid=ATVPDKIKX0DER&psc=1 because im not clear at what is the ideal weight for a nd filter for not stressing the gimbal, any advice in the decision is really valuable, thank you!!
