I'm thinking of taking 2 8" arms (per each side) to use with my 10.5Dx lens in Alaska. Here is a shot I took in relatively poor conditions off of Santa Cruz using the 10.5 and the same 8" arms. It seems you can get a shot without a lot of backscatter in poor contions with carefull placement of the strobes. (DS125s with a diffuser on them)

 

What is you impression of the lighting? Okay with little backscatter or hot spots? Or should I bring my two longer arms?

Dave,

 

For me the answer is all about your expected camera to subject distances. The longer the distance the longer the required arms.

 

For example the day before yesterday I was shooting in 4m viz with the fisheye using single 8" arms. This was fine because I was only doing close focus wide angle.

 

While in better Viz in Sipadan a few weeks ago (say 18m) I was using double jointed arms because I was shooting subjects further from the lens.

 

If the example shot you post is what you plan to shoot then I think you are fine with double jointed 8" arms. If you are going to shoot bigger subjects or from further back then maybe you want a big more. If you are going to do CFWA then you could get away with single 8" arms per side.

Thanks Alex. I think I will take the 12" arms as well. I got a number of good diver shots on this last trip; but I noticed some backscatter in the edges of the photos a a few had hot spots on the out side. I think strobe placement may be easier with longer arms available.

 

I was impressed with how well the 10.5 does wide angle in mediocre visibility conditions.

Longer is better. The (2) 8" arms will work but if you have longer arms, take them. The 10.5 is so wide, that I was constantly having to adjust the arms to move them behind the 180degree field of view.

 

I am still debating the benifit of diffuser vs no diffusers with the DS125s when shooting the 10.5. Anyone else have an opinion?

I don't like diffusers too much on my SS200's, I really like the "hard" light without diffuser. In my view it gets too "soft" with the diffuser.

FWIW I have not found the diffusers on the DS125 to give any benefit.

 

The DS125 does not seem to produce such a 'hard' / 'cold' light such as say the Innon units.

 

What the diffusers do for you is seem to drop about a stop which makes things tougher than they need to be.

 

After my first trip with the diffusers I quit taking them on trips - they now sit in the box at home.

I use the diffusers on almost all my 10.5 photos not because I like or dislike the light it gives, but because without it id need 3 strobes :)

I notice a difference. In my dark local water, where you really need strobes on the whole foreground, there are times when I take the diffusers off for that last half stop of power, and there are times I want them on for the additional width.

 

i'd bring them. They don't weigh much.
