Anyone have any vignetting issues with the 50mm non-C? I taking a step back in time by getting rid of the digital SLR and getting an RB67. Just had my first trip with it to Iceland and had a few frames with some vignetting or light fallow on the edges. Not sure if it was my filter or something else? Thanks

That is a bit perplexing–I have a 50mm C and haven’t noticed any vignetting. Please, keep us posted if you discover it was the lens.

Probably should have posted here instead…..apologize for the repeat.
I recently purchased some Mamiya RB SD gear separately from all over the place.
I just received the 50mm RB Sekor C Lens, although I haven’t received the Mamiya RB SD Body as yet.
There is a noticeable clunking sound as some slight glass movement, just wondering if this is normal as it might something to do with the floating element or is it a defect? All appears normal visually.
Also this lens has a silver collar on the rear of the lens, would it signify I will absolutely need the Mamiya Spacer Adapter for use with the Mamiya RB SD? Your replies are greatly appreciated. -
Hello! I’m having a technical issue that I was hoping someone could help me resolve. I own an RB67 Pro S and just recently purchased the Sekor C 50mm f4.5 lens. The issue is, I just can’t get the lens to seat on the camera body. Is this lens even compatible with the camera? Is there an adapter I need? Your help is greatly appreciated!

I hope you figured this out, but my thinking would be if somehow the ProSD adapter ring was put on somehow? I believe you’d need to remove the sleeve to make it fit the ProS body.
