Rolleiflex filter thread?

[Tjibs]

I noticed my Rolleiflex and cord (Xenar lenses) have a 27mm filter thread, where filters and hoods screw in perfectly. I however once read this was a bad idea, but I do not understand why. Does it cause vignetting? I have a few 27mm filters that I'd love to use.

I'm looking at my Rolleicord TLR with Xenar lens if this is what you are referring to and the lens takes Bay 1 filters or hoods. I think people need to know more about your camera so you get the answers you need.

The OP answered his own question, the inernal thread will vignette if you try and use filters.

Thanks Ian. I didn't answer my own question, it was just the only thing I could think of, and was unsure if this was true.
