I'm thinking of finally switching to monochrome, preferring the 533, I currently have the color version as my optical set with an Askar 91F, which 36mm filters are good and which should I consider?
You don’t need 36mm filters to image with the IMX533, 1.25” are plenty enough. This said, what is your budget?
I cannot recommend the Touptek AFW, at all ( I have this one, regrettably). Filters, I’d go with the Scorpio and get a decent FW from PlayerOne. You’d need to budget for NB filters too, again the Scorpio win. That saves a bunch of money and headaches sorting out the FW connection issues.
I haven’t had the troubles with my Touptek filter wheel that others have alluded to. That said, It’s all anecdotal evidence, even mine. A single experience is close to meaningless. My best advice would be to go with a main brand that fits your needs and budget.
