I only found these images so far. I received the SC600fd Plus MK IV and it looks quite nice. I can’t fire it up yet as I’m waiting on the batteries. One thing I’m a little concerned with is the tail cap. Is it normal to have so much slop between the body threads and the cap threads? When I thread the cap to the body it feels quite sloppy/loose. It’s as if the threads have too much gap. It isn’t loose when you thread it to the end.If you slightly unscrew it it’s a sloppy wobble feeling. It seems to have zero resistance twards the end when the cap seals up with the oring on the body. It’s definitely different than the SC5w MK II’s tailcap / body screw on feeling. Is this normal for Zebralight SC600 ?
