View Full Version : WooHoo! Pro-1 has ND filter (or does it?)

I was looking over the PDF brochure for the new Pro-1, and I noticed that the diagram of the LCD display panel includes the built-in neutral density filter, just like the G3/G5 (see below). Wonderful! :D This is the first reference I've seen to the ND filter on the Pro-1 anywhere. Then it dawned on me - the LCD panel shown is EXACTLY the same as it is on the G3/G5. Could it be that whoever wrote the brochure was just being lazy, and used an old picture? Was Canon being lazy and they're using the old LCD on the new camera without actually having the ND filter? The rest of the brochure doesn't mention anything about it, and I haven't found any other reference to the ND filter anywhere else.

Does anyone have the real story?

Online specs page mentions nothing about ND filters... Probably none there.

I have seen the ND referenced elsewhere but here is a link showing it's included. http://www.canon.co.jp/Imaging/pspro1/301-e.html#10 :wink:

Could you maybe explain what exactly the ND filter does? (I have a Canon G3, I never use that one!).

The quote from the link above says:
The brightness can be decreased by setting the ND filter on. This allows you to select a smaller aperture value and a slower shutter speed than usual.
Standard brightness is decreased to approximately 1/8 when the ND filter is on. For example, if the appropriate aperture value is 8, it becomes 2.8 when the ND filter is on.

Others will know it better but basically, you can take shots in bright light with longer exposure times (thus getting flowing waters, etc.) without over-exposing.

Great link, KRDV. Thanks! I guess its official, then.

KRDV pretty much explained it, but just to expand on the subject, sometimes there's just too much light for the picture you want to take. One example is below. I wanted to get the running water to have that "cotton", flowing look. This needs a longer exposure time. Even at ISO50 and f8, I couldn't get a long enough exposure time without having the whole scene look way too bright. The ND cuts down the light by 3 stops (which is another way of saying it only lets 1/8th of the light through).
