Developed my 1st 4x5 negs on Sat. They are stupendous. Now, I'm already craving a nice folder. I am interested in a Zone VI Field I've seen. It's mahogany w/ balck anodized fittings. The seller assures me it was made Zone VI and is not one of the several permutations of this camera. So, firstly, what is the value of this camera w/ two matching lens boards in Mint condition? What features does this camera offer that make it worthwhile? would I be better served by purchasing a Shen-Hao? ANy users of the Zone VI able to comment or offer caveats?
