6x17 with Singh-ray Vari-ND filter questions

[zane_yau]

<p>Hi guys<br>

I am looking at getting a 6x17 camera which comes with a 90 F4.5 Nikkor lens. My problem is that this lens has a filter diameter of 82mm.<br>

I love doing a lot of long exposure photos which require the use of a Hoya 9-stop ND400 filter and the only strong ND filter which has 82mm thread in the market are:<br>

1/ Singh-Ray Vari-ND 82mm (2- 8 stops adjustable) - standard ring;<br>

2/ Singh-Ray Mor-Slo 82mm (which is a 5 stop ND filter)</p>

<p>My questions are:<br>

A/ Will these filters cause (hard edge) vignetting on the 90 F4.5 lens?<br>

B/ I have heard reports of uneven exposure for wide angle shots with the Vari-ND?<br>

Keen to hear your experience.<br>

Thanks!<br>

<p>Hi Zane,</p>

<p>I shoot some wide-angle landscapes with a Pentax 67 (45mm lens) as well as a Fuji G617, which has the 105mm lens. I have to be very careful about uneven exposures when I use a polarizer on either of these lenses on bright, sunny days, so I would expect that you'll also have issues with this lens...</p>

<p>Good luck,</p>

<p>Have you considered filter holder systems with gel or resin filters, e.g. Lee? These offer fairly large sizes and you could also utilize an ND grad if you want.</p>

<p>Thanks Tim/Oskar.<br>

I didn't know Lee or Cokin produce square filters which is similar to the ND400. I will check them out. Thanks</p>
