I am considering purchasing a 240mm f9 Doctor Germinar lens (I am told the optical quality is as good as the Rodenstock equivalent at half the cost)I would appreciate any comments from readers familiar with this optic.

Are lenshoods a good idea to use with large-format lenses...I never seem to hear or see large format photographers using them!And if so,what are good brands to look out for?

How practical are Groundglass Protectors;I carry my 5x4 in a billingham,would it still make good sense to invest in one or are they just a gadget for me to part with my money.

I recently dropped my 210mm Schneider during a shoot.The front element has a dee p mark.I am told that because it is

on the front element I should not worry,and because Schneider lenses are multi c oated.Is this true? I have used the lens in question since without any differenc e in image quality.
