Here’s a question for the Nikon Brother/Sisterhood… Can a Nikon p/n 2370 viewfinder adapter be used with a Nikon DR-3 right angle viewfinder? What I wish to do, is use a DR-3 (with round finder attachment) on my D200 (rectangular finder). The 2370 adapter sounds like it might work for this purpose, but I’m unsure if the threaded barrel size of the adapter matches that of the right angle viewfinder. The question had my local Nikon retailer scratching his head, and I’ve not found anything definitive on the Internet. Nikon makes a rather spendy right angle finder for its rectangular finder cameras… But I’d rather not spend big cabbage on an accessory that will see only limited use. Thanks in advance for thoughts and ideas.
