I have a Olympus OM-D E-M1 for underwater use in a Nauticam Housing. Now, when i Review my Pictures, i see, that in my opinion the camera doesn´t perform that good in the high iso range. Deep down in the Attersee (lake in Austria) and also in wrecks and Caves in the red sea i took picturess with the 8mm Panasonic at iso 3200. At iso 3200 there are really few Details in the Pictures and the Picture is very grainy. Can anybody report of expieriences with the E-M1 and low light. Which is the maxium recommended Iso for a reasonable Picture Quality? It seems to be better to use f4 and 1/15 at iso 800 with the possibility of unsharp, blurred Images because of movement then Pictures at f5,6, 1/30 at Iso 3200 for Pictures with really less Details and colours. What is your expierience? Best Regards Armin
Hi, I take most of my UW images in dark conditions with a low level or lack of ambient light using high ISO, a large aperture, slow shutter speed and stobes. The OM-D is a great camera in that kind of environment thanks to the 3-axis image stabilization and good low-light performance. However i have a problem with the built in flash when triggering the external strobes. Light is leaking out through the housing and dome causing backscatter in the center of the images. I'm using a Panasonic 8mm + Nauticam housing with the 4" fisheye dome. This is only a problem in dark conditions described above. I have tried to reduce the power of the internal flash, but the it sometimes fails to trigger the strobes. I have seen some LED thingy that can be used instead of the internal flash. Is anyone using this and have some experience from it? The attached image is not the worst example since you have some surface light, but you can clearly see the backscatter and in darker conditions you will se stripes of backscatter like in the second image shot in the housing with strobes turned off against a white wall. f/3,5 1/20 ISO800 @8mm
