Filter for Xpan 45mm lens

[Ben1]

Hi all,

Just wondering if anyone knows much about the filter to correct light falloff at the edges of the xpan pics. I know hasselblad have their own one-stop centre weighted filter to correct this "problem" but from what ive read it costs a bomb!!!

Would a B+W 49mm Neutral Density 2x (1 stop) filter do the same job????
I can get one of these for $55 Australian so im gonna save myself a small fortune if that will suffice..

If not, can anyone suggest a filter to correct the problem that wont cost me an arm and a leg!! (if such exists)

Thanks

I use my 45mm without the center filter even though I own one. Pics still come out pretty ok with no apparent fall off. The 30mm is another story though, it does require its center filter.

I used mine extensively with just the 45mm and NO center filter and I have very apparent fall off. But honestly I like it quite a bit. BTW, this was with b&w film.

These are a couple of shots with the 45mm w/o the filter... f/8 - f/11

An ordinary ND 2x filter won't work. It needs to be center weighted (darker in the center than near the edge), and whether it would work correctly depends on the gradient of the center weighting.

I have never used a filter with the XPan II and 45mm lense and haven't had problems- with Provea 400 (color slide) and b/w neg. I think it's a matter of personal decision. Do some film tests and have fun.
