Played with a Heliopan RG695 IR-filter on the XF 14/2.8 (X-Pro). Still have to find a workflow for this IR-kind of stuff. Ernst-Thälmann-Straße von georgsfoto auf Flickr
Handheld IR + "„Socialist Classicism”“ - X-Pro/XF14/Heliopan RG695
ISO1600 - f/4.5 - 1/30sec
Exposure was very slightly different and both were handheld.
Zeiss seems to be a touch warmer I think.
Hoping to test properly (on tripod with exposures locked in) next weekend.
Would't buy the Zeiss at the normal price because the fuji is good, but at the price I got it was worth a shot. One of the 2 will end up on the buy & sell board in a few weeks once I'mm happy with my choice.
