Nexus D90 housing / fibreoptic cable set up??

[roby jeff]

I'm trying to finalize purchasing a housing for my D90 and have decided I like the small Nexus housing with Z240's and small Tokina fish eye dome. My question is to anyone who is using nexus fibre optics is deos the camera's flash recharge time between shots slow the camera down when shooting repetition . ?????
I don't like the thought of waiting 4 or 5 seconds between shots when the recharge time of the strobes is only max 1.5 seconds.
:confusedWould be keen to find out others experience before i place my order!

My reference is a Nexus D300 system using f/o & YS110's or YS 27's. In my camera menu I set on-board flash to manual & power setting to 1/100 full power. I've found very little effect on camera battery life. In continuous shooting mode (CL or CH) the strobe will only fire on the first shot. Have to use sync cord to get external strobe to fire each time, but the strobe's recycle time would have to keep up with CL/CH shooting time (3-6 frames/sec for D300). Camera flash fires pretty fast (~1-2 sec) in Single shooting mode, so you should be able to keep up with the Z240 recycle time using f/o. Hopefully the 90 is same as 300 in this regard.

Thz jcclink heaps for your reply & helpfull info.
I have looked at the D90 manual and appears I can set flash power in manual stobe mode from full to 1/128 probably the same as your D300
Would seem with Nexus i have a STROBE FUNCTION choice of:
1.... camera flash set on the default TTL as is , which will also give me auto TTL contol of the strobes power ...but be a heavier draw on my camera's battery.
2.....or set camera flash on manual and reduce it's power output and then set strobes to manual and adjust them manualy.

Is No 2 the method you are using or am on the wrong track??

I'm using method #2, starting with strobes set on 1/2 power. Adjust as necessary to get f-stop I want. Not really familiar with Inons so can't advise on their TTL function. Since I've always shot in manual mode, this seems to work well.

thanks again jcclink
i've used my manual strobe adjustment previosly with out difficultly so now i understand i'm comfortable it all. Apparently TTL is not very good on WIDE ANGLE anyhow.
now just got to decide whether to get a mag viewer and whether 45 degree or 180 straight.
cheers

I havnt had any problems with TTL when shooting wide angle. It works for me.

Just chatted with a chap using a Nexus with TTL operating and the Tokina 10-17 & he loves it so I guess i'll see how it all goes.
I've ordered the nexus with 2 x z240,fibre optic cables, float arms & 45 degree viewer. Should have it all and be taking u/w pics in about 3-4 weeks. we'll use the fish eye to start with and move onto the 60mm lens when we get the hang of it all.Will post a pic of the set up and a couple of u/w pics when we get into action. I'm sure to have questions, i can see using the D90 and this set up is more advanced with has more potential than we've been using.

Might I suggest starting with the 60mm first. It's pretty easy to shoot compared to the fisheye. I just got the 10-17, but haven't dove it yet. Expecting a bit of a learning curve with it - different strobe placement, power settings, etc vs macro.

i already have the 10-17 so will have to work thru it. Would be interested to hear how you are going with your fish eye and any methods that are working for you. i'll also do it but suspect i'll have more questions than answeres.
cheers

the 10-17 fisheye lens is heaps of fun
just been messing about with settings but slowly geting there. I've been using TTL all the time with some fine adjustment with good results . here's a coral cavern pic i liked that fitted in with the 10mm.
