Sigma 15 FE & Nauticam D800 .... when Teleconverter?

I ask myself for which kind of pictures I use fisheye without and when with 1.4 Kenko Teleconverter?

D810 and shutter speed

13 August 2017 - 03:34 AM

I read always, that on surface the D810 has a problems with by normal shutter speeds, and the new 1/125 should be 1/200 to avoid receiving no sharpness.

While diving with my D810 in Nauticam / Zen 170 and Sigma Fisheye I havent identified this effect when using 1/125 shuter speed......can this be an effect from flash? Is the flash speed maybe freezing the picture?

Best regards! Sascha

Flash duration?

13 August 2017 - 03:26 AM

I have questions for the Pros:

- how long takes a flash ignition normally?
- I read in the web different meanings about the power of flashes: on one side it is stated, that a flash ignits always with the same power when using different power levels, it just differs, how long the flash ignits. On the other side it is stated, that the the power is modified and not the time....whats correct?Whats the best book orwebsite to learn more about flashes UW.....in use with ambient light?

Best regards, Sascha
