    Backscatter macro wide 4300

    In general, using a video light even a very bright one is an exercise in high ISO shooting. If you think about light output, the YSD2 is about 5 orders of magnitude (100,000) times as bright but for 1000 times less time on. It can be done, and it will work but color balancing in post will be...

    How come I've never seen a focus light on a locline?

    There are two issues for using locline. Many (most) video folk use Locline but there are very nice locline adapters for most video housings. On photo-centric housings there is no really good way to mount a locline arm. We use these for attaching to the housing. Secondly you need a locline...

    Can someone explain the microscope settings at a kindergarten level? :-)

    There are only 2 apertures on the TG system. The effect of other apertures is created using a 3-stop ND filter. This is a surprise to many folks but it works (sort of). At the wide end the aperture is f/2 or f2/8 and f/8 with the ND filter. At the tele end the aperture are f/4.9 or f/6.3 and...

    I think it's time to invest! 📷

    For wreck and other wide angle pursuits, you could easily get by with an APS-C system and the Tokina 10-17 or with the Micro 4/3 system (OLY EM1 Mark II or Pany GH-5) and say the Laowa 7.5 mm or the OLY 8 mm or Leica 8-18. I shoot micro 4/3 and really like the size, particularly the ports which...

    Canon RF 100 Macro Lens

    Haven't tried that. Other lenses with the adapter (8-15) are also fast but hard to tell with that lens. Bill

    Canon RF 100 Macro Lens

    No dome, just the flat port. Focuses much faster than the 100 macro on the 5DMKIV. Bill

    Nervous about upgrade: Subal w 7D -> Nautica w/ EOS6 (long!)

    Which camera? I thought the Nauticam R6 housing was already out. I have used Nauticam for years now and I think they are as durable as my old Subals. Parts for Nauticam are available everywhere so that should not be a worry. Going from cropped to FF is indeed an interesting issue, are your...
