Keep us posted, Ronn. I'd love to send them both of my invoices.

@Andy
Thanks a lot! The comparison EX1 / EX1R without filter looks as if the EX1R would even a little brighter. Did you use same gain and iris settings? Does the EX1R have at leat exactly the same sensitivity (with same noise) as EX1R? Thanks again, Markus |

Good question. I didn't notice that it was any faster because I was just testing the IR issue and eye balling exposure. I reviewed the two clips in the Clip Browser and I can see that the EX1 was set at a F2.2 and shutter of 89 degrees. The EX1R is at a F2.5 and at a shutter of 103 degrees. They were both on STD3 gamma and at 0db Gain. So it does look like the EX1R is a bit more sensitive and the noise level is right about the same. |

I might take the opportunity to get a Tiffen instead though - as people have said, they're relatively well priced. Never having tried one I've nothing against them except earlier reports on this forum: a greater overall colour cast, mid-greys may be tinted green even after a WB, and a one stop loss. I need as much sensitivity as I can get as I record underground a lot and don't like to use any more than 9dB gain. What I like about the 486 is that it has so little attenuation at visible frequencies that on auto iris the ring hardly moves when you put the filter in front of the camera. I would be very interested if someone could post EX1/3 shots of a greyscale or a Munsell/Macbeth colour chart, with and without the Tiffen but with the camera on one preset colour temperature for both, to see what it is doing... |
No tiffen T1 IR filter for the Fujinon W/A zoom lens. I'll have to tape on a 4X4 to the lens hood.

BTW, the Acquisition tab of the new Clip Browser is a fun to watch - especially when, for testing purposes, you set the camera to Auto everything... Sudden changes in ATW measurements, focus hunting - really educative! |
It wasn't full auto anything... just set to 23.98p with a second based shutter. But doing the math 89 degrees =1/97 and 103 = 1/83, which is equally as strange. Perhaps the flicker reduce feature was doing something as well. So Piotr I'd have to agree that something is not right.
I do love the Acquisition tab though, fun to watch the settings as they change. |
