I've ordered this lens and supposed to get my hands on it this weekend, it is currently available in Japan and the lowest price is Y343,875, which is about 4100~4200 USD. I will keep you guys posted.

?????? D FA645 25mmF4AL[IF] SDM AW??????:????? ??????????

For the GND filters, since the lens is about 90mm wide, the conventional 100mmX150mm filters may work for 645d (probably not for any 645 full-frame sensors).

Assuming you're getting te lens from Japan, are you having the store ship from Japan or is someone buying the lens for you?

Anxious to hear your impressions.

I know a few photographers who use lee filters with the Zeiss 28mm f/4 lens who haven't had any particular difficulty with using such filters on FF MF though there is a limit using two filters in front of the lens with the SW150 filter holder. My own use of the nikkor 14-24mm f/2.8 with the lee SW150 filter holder has been enjoyable, however the holder attaches to the lens barrel itself and it is a rather cumbersome device to fit in a camera bag. Lee provide a 0.6 grad 150mmX170mm filter with the holder they also have a small assortment of other filters available in the 150X170mm size. However, they have informed me that they will not be making a "big stopper" or polariser for this holder - so we are fortunate pentax will be providing a polariser for the internal filter holder with this lens.

The internal diameter of the filter holder itself will easily be large enough to accommodate the 90mm diameter of the new pentax 25mm f/4 all Lee has to do is produce a collar to fit.
