2. 82 mm Schneider Kreuznach is really difficult to order outside the US. Neuro, how is yours going? I need to put a 82 on my 21 CZ Distagon and want to step down to 72 and 67 over adapters.
Finally had a brief chance to try it yesterday, in between rain and work obligations. The scene is a busy area of downtown Boston, the reflecting glass is side of the Hancock Tower, the tallest building in New England, dwarfing the Trinity Church across the street. Shots are with the 5DII + TS-E 24mm f/3.5L
II, +10 shift.
The first shot is a 1/6 s exposure, the second is a 30 s exposure during which several pedestrians walked through the scene, along with cars passing between the buildings. Thanks to the long exposure, they're not visible.
Like my B+W 77mm 10-stop ND, this 10-stop filter does warm up the color temperature a bit - I didn't correct in post because in this case (dull gray, overcast day), I think it's beneficial.
