I am searching for a focusing light with a narrow beam and integrated flash sensor, I want to use the light for mounting on top of the camera, help the camera to focus in dark water with poor visability. For that it would be good if the light has as a spot spot 500-1500 lumen. Quick Change to wide and red would be perfect, but not the msot important. The Problem is, that when I use higher Iso and a wide open aperture, then the light of a normal torch is visible on the Photos. For that it would be great if the light automatically turns off when I take a picture. Does somebody know such a light or give me a tip? Thank Armin
Hope i am not creasting false hopes, but what i put in the title is something i would loooove that Olympus puts in place. What this is about? It's about the great ability of the Oly 60 mm 2.8 macro lens to restrict the focusing range within a limited distance, in order to optimise the autofocus speed. Capability to access this setting underwater would be maravellous for obvious reasons, and would reduce the gap in Autofocus speed versus DSLR cameras (i often miss my trusty Nikon D300 in that area). Actually, this would be useful in about any lens i think, even on a fisheye, if you know you're shooting CFWA why wouldn't you like to limit the focusing range from lens glass till, say 10cm. From a product positioning standpoint, Olympus are very concious about underwater photography (they manufacture housing), so this would be in line. I would personally be ready to upgrade to a newer camera for that single reason (well, increasing battery life wouldn't hurt either...). Feasibility? I am not an Olympus engineer, but with the number of things that can be electronically controlled in Micro 4/3 system, i am pretty confident this would be doable. Take the example of the 12-50mm zoom lens, i think there's some ability to get to the "macro position" electronically. So how do we get it done? Two years ago i dropped a hopeful email to Olympus but didn't get any answer. Any other idea on how to get their attention? I guess the first step would be to see whether you guys would also like that capability. And if there's a few of us, discuss what's the best mean to convey that suggestion to them (photo show, some ideabox...). Thanks in advance for your comments! cheers Nicolas
