Looking at some Contaflex literature, there is no mention of a ND filter being offered. I have seen other 27mm ND filters, though (Heliopan, Hoya, etc.). Perhaps you could use Series V filters? There are old 27mm threaded to Series V step-up rings available on eBay (I used to have a Tiffen one for a Smena-8) that should be compatible. The Ser. V filters are mostly drop-in type but they were some available with threaded mounts too, including ND. -

Vivitar Series 1 105mm f/2.5 macro on Pentax K-70 -
Hi, I use third party macro/close-up filters attached to a trail camera for filming wild birds, and other small animals, at close range. With the trail camera I have at present I am using vintage 27mm contaflex filters. I have two sets (+1, +2, +3) one made by Bittco (Super Vemar) and the other Vivitar. I use a Zeiss-Ikon (S27) Sykylite filter with the glass removed as an 'adapter ring' for attaching the macro filters to the trail camera lens. The results are quite good considering . This video shows the method and some sample clips: Campark TC02 Macro Filter Modification That said, the auto-exposure control on these trail cameras (invariably aperture priority) has it's limitations and struggles in bright sunlight. I'm wondering, were 27mm neutral density filters ever produced for Contaflex filters ? I regularly scan EBay but have never seen one listed. I've thought about using a larger size ND filter (say 37mm) attached to the macro filter with a step-up ring, but one thing I've found with these Contaflex filters is that the low profile, fine pitch thread is not compatible with 'generic' step rings, at least those I purchased on EBay (from China). -
When a Minox winks, it takes a picture. But when I bought the first Minox A with defective shutter blades, I had to know more… This Minox A was a flawless beauty, but you could tell from the outside that something was wrong with it. Through the glass window in front of the lens I could see that the shutter blades were destroyed. The camera could not be cocked and certainly not triggered. It was a disgrace. On the other hand, I had bought it cheaply and so I had the courage to repair it. It became a very long road. But I wanted to know and so I created a documentation of how the mechanical shutter of an 8×11 Minox actually works. I took notes and lots of pictures. And as is often the case in life, if you delve deeply enough into a topic, it becomes more and more fascinating. So here it is for anyone who also wants to know how the Minox shutter works: https://moments-of-now.com/how-the-minox-shutter-works/ Please note that this is not an actual repair procedure. Rather, it is intended to describe how the shutter works. It is also aimed at those of you who do not want to repair but are interested in Minox technology. -
