Hi all, I'm new here and new to LF - so it's all a bit daunting!

I may have made a boo boo - I've just got a Ebony RSW45 and a second hand Rodenstock 55mm f4.5, I'm now worried that the image circle is too small at 163mm at f22. Is this image circle OK with the 4x5? It's on a recessed board, would it help if it were a non recessed board, will it allow for ny movement or would it be OK at a smaller aperture?

As I say, I'm new to all this so it's all seeming a bit complicated!

Oh yeah - Can I not use standard filters with this lens either, as it's so wide angle?

Thanks for any help
