Quote:The 350D era camera does not have the LPF-1 LPF-2 filter arrangement, there is only one filter in those cameras.
Quote:I've tried searching the net for any answers, but couldn't find much. There's this page, which shows the Baader ACF filter response in IR being somehow higher than Canon IR cut, which would be good news for me. There's also a test photo, taken with a 780nm filter, which further confirms the Baader ACF allows more IR through than the original IR cut - I'd never get an exposure time of 1/2s on ISO 400 f/7.1 with 780nm filter on my unmodified 350D, I'd maybe get there on ISO 3200 and f/3.5. But - there's that ugly flare on the left in that image that worries me...
