In Topic: SB800s underwater

17 December 2005 - 04:53 PM

I think I remember hearing that some people think they aren't as good as an UW strobe for main lighting. Also I don't think the slave sensor/wireless control would function under water.

However, none of this may be true. I am interested in opinions on just using 2 sb-800s as main lighting though if you could keep TTL function.

In Topic: Wide angle for 1D Mk2

While I was cruising the Subal port selection page, most of the wide angles from Canon and Sigma can fit under the Fisheye Port. So I can use a fisheye, wide prime, wide zooms, and a few others. All I need to change is extension rings and diopters.

I think that Canons fisheye is supposed to be a top notch performer. Most people complain about the 14mm ($1800) and the 16-35 ($1300) to me, paying almost 2 grand for a lens and not having good performance isn't that useful. But I also think that somepeoples expectations are a little high for such a wide lens.

Alex, that flourescence article is super interesting.

The close focus is 7.9" for anyone who may be interested. The Subal site says a +2 diopter and EXR40 to work properly.

It's too bad about the Canon wide angle lenses, I know they are not great on the edges. Maybe someone can figure out how to put Zeiss and Leica lenses in a UW housing and operate the apeture. :D

The more I think about using the fisheye UW, I think that having too much in the frame could be a problem. I know working on land I don't like superwide lenses as it makes it very difficult to frame the picture properly. Too much unwanted stuff gets in the frame.

I think I'll probably get the 20 1.8 and the fisheye Subal dome, that way if I want to use the 15 fish, I'll have the port already. I do want to use a prime due to the fact that I want the better image quality and loose a little bit of the versitility.

Thanks for all the advice

I'll check out the fisheye, do you think a 20mm prime would be wide enough on full frame? I know I'm getting the 1DS2 in the spring, its my motivation to get into grad school! :D

Plus I will be using this lens a lot above water and I don't know if I want to deal with the fisheye perspective all the time.
