I need some advice from all the LF experts on the site.
I am using a Wista 6x9 roll film back on my new Canham 4x5 DLC. I want to use a wider lens than my current 75mm Nikkor SW. I am considering several lenses in the 45-47mm range, solely for use with the 6x9 format, and possibly a 6x12 roll film back in the future.
I am getting some conflicting advice. I have been advised that the regular 47 f /5.6 Schneider SA does not have have sufficient coverage for the 6x9 format. So me folks have told me it affords very little possiblity of movement, and it has significant light fall-off at the edges, requiring a ND center filter. Others s ay the opposite.
I've also been told that the newer, more expensive Schneider 47 5.6 XL SA needs a center filter as well with the 6x9 format, even though the coverage afforded i s significantly more than the regular Schneider 47mm f/5.6. I would think if th e coverage were sufficient for up to 4x5, the XL would not require a center filt er.
Additionallly, several sources have advised using the Rodenstock Grandagon 45mm, instead of either Schneider 47mm. They claim it not only has sufficient covera ge/movements, but, surprisingly, it does not need a center filter with the 6x9, and larger 6x12 format.
Do any of you have any personal experience/thoughts on these lenses with the rol l film formats? Thanks for your help, Sergio.
