+1 for sticking with the 12504 + Series VII filters. Cheaper 12504 replica hoods are well made but luck-of-the-draw items: some sit tight, others are prone to spinning. Or, for the modest sum of $300 😮, you could buy a replacement front "steel rim" from a couple of Thai sellers on eBay. Seems to be designed to allow screw-in filters to be used on the v2. I have no direct experience with them, though.

They can be busier on weekdays...😉 M10 + 1952 Canon Serenar 35/2.8 @ f/4
