#393143 Introducing Nauticamís WACP - The Wide Angle Corrector Port: Discuss Here

Posted by twinner on 09 March 2018 - 09:14 AM

Hey Jordi,

 

f/5.6 is not going to be as sharp as f/11 or any high f stop but it is sharper than a dome at the same f stop and same FOV. That image in the cave is a bad example as I shot it with a slow shutter speed and probably introduced some camera movement. Overall I find it to be much sharper in the corners than a dome and the zoom range is pretty incredible.

#361668 Nauticam CMC with Canon 60mm

Have a great trip! She will be happy with the SMC and 100mm combo. You can also stack the SMC with the subsee +5

Here are some examples with that combo and the SMC plus the Nauticam multiplier.

One more vote for the f/4.0!

I recently replaced my f/2.8 II that was stolen with the f/4.0. The f4 is better all around unless you need to shoot wide open at 2.8. Here are some recent images with the f/4.0 https://samysunderwa...usm-underwater/




#338258 Canon 16-35mm f2.8L II Dome?

You are going to need the proper extension ring with any of theses setups. I use a 70mm with the Zen 9" and nauticam housing. I,m not familiar with the pro-one domes so I can't comment on that one.


#338254 Canon 16-35mm f2.8L II Dome?

Posted by twinner on 17 October 2013 - 07:15 AM

Unfortunately all rectilinear lenses lack some corner sharpness behind a dome. The best solution is to use the largest dome you can and stop down on the lens. I use the 16-35 II with the Zen 9" without a diopter on 5D Mark III and find the corners quite acceptable. On a cropped body the corners will be even better. By adding a diopter you may add some sharpness to the corners but I don't think the 16-35 II needs it.
