  • Is it misunderstanding?  I meant is plastic housing with fibre optics support so far I know is S&S RDX series.
    Metal I know seatool, aquatica (Scubacam). From S&S metal housing version with fibre optic support is 7D and D300s (Nikon) all this housing allow to mount built-in flash full/partially open to trigger external flash via fiber optic.


    I see I see.... I think thats why we use 10Bar Fiber Optic cable that use a velcro system for OEM casing.  ;D

  • With regards to using FO with ikelite housings, it's possible with canon DSLRs as you can tirgger the flash even with the flash 'half popped' up.

    There are a couple of concerns with using FO with DSLRs. I'm using a Nexus 50D housing which allows me both options and i've tried both.

    1) Using the camera Pop-up flash allows you S-TTL/E-TTL with Inon/S&S strobes. However.... You have to take into account the flash re-cycling time on your camera meaning that you're unlikely to fire off multiple shots and you'll be stuck waiting for the camera flash to re-cycle. I think this is especially true shooting macro at high f-stops.

    2) Cameras like my 50D doesn't allow you to control the flash output manually, which may be an option to some DSLR users. But if you're manually controlling your camera flash output to save battery, lower re-cycle time etc, then you might as well go the hard wire option and control light output manually on your strobes.

    Canon EOS E-TTL II now is already incorporate lens-subject distance for flash output calculation, even on min f-stop (f16-22) if the distance is short built-in flash will not go to full dump (Canon flash capability is catching up with Nikon). Another trick is to set flash exposure compensation to -2 ev when using manual flash. For me I am using DS TTL if I am doing macro since the exposure is quite accurate and manual mode if I am taking wide angle.
    Major draw back for FO connection is battery on camera will run out juice faster due built-in flash keeep firing.

    It still takes a couple of seconds to re-charge the flash. Which to me is worse than your camera running out of juice as you can monitor and change battery after dives. Not being able to take a shot or missing the moment is much worse to me.

    I'm used to getting quite accurate lighting with manual control of my strobes already. Rest can be fixed in PS most of the time. Also shooting on manual controls allows more creative lighting techniques to be tried.

  • If flash not going to full dump it will recharge in a zest, for me I can still do 3 continuous burst shoots before built in flash going into full recharge. My problem is more on my YS-110a going full dump and I got black pictures for next 1-2 frame until my external flash ready to fire again. This is the reason for me to get 2nd flash reluctanly, 2 flashes more light and to reduce external flash going to full dump then take 2 secs to recharge.

    Different approach of doing photography, for me it's important to get it right the first time and minimum PS. Maybe I still treat digital photo like when I was still doing in 35 mm film. I don't like to stay hours in front of computer editing photo.
