@jimtreats AFAIK the shutter speed/focal length 'rule' traditionally applies to still photography and was based on the 35mm (equivalent still camera) format you refer to. However I think you are confusing movement within the scene itself (ie people moving about, trees blowing in the wind etc) versus camera shake which is exasperated by longer lenses.

With an over the shoulder support and two front handles plus eye contact on the EVF you should have no problems shooting stable footage with a Canon FD 100mm f2.8 lens without any electronic stabilization. I use this lens a lot, there is no hand jittery, only gentle wavering which doesn't blur the footage shot at 1/50 or 1/60

True hand held, just the camera 50mm max,

Thanks everyone. Nice to hear actual examples of what people are using. With my own footage, excluding the image stabilised 14-140mm that I've got I've definitely noticed my footage is best handheld at 50mm (FF equivalent). It's one of the reasons that eventually swayed me to get the 17.5mm lens as i realised it'd have to help sharpness and generally improve wobbliness relative to its 25mm brother.

The other thing i realise is perhaps its technique or just individual stillness of some of us, ie. maybe i can be a little too jittery for my own good! @Rambo you must have epic technique to be able to hold a 100mm lens (200mm FF equivalent) steady, even with a rig.

I do have a flycam nano steadicam which helps a little, but has limits. I also have one of those really cheap plastic pincer shoulder mounts which does seem to help a little... I've got a real urge to pickup a better shoulder support though, and the idea that it could let me hold a 100mm acceptably (and more comfortably) is rather appealing.

I've wondered about basic pistol grips as well... they seem to help, but its not clear how much... I do like the EVF on the GH2, though i find it just a little too hard to sometimes nail focus with it alone... really hopeful that the GH3 improves on this.. be nice if it had a great screen, as well as an improved EVF.. choices choices then. It does seem that using a loupe as i did on my old 550D gives you more options for tight point of contacts and if the screen quality is good enough almost monitor-like abilities to read the focus... well we get to wait and see on that front i guess.

Thanks again.. i guess i'll hold fast on the Oly for now. The 14-140mm has done good for me in the past, it just struggles so indoors. Still my wallet will be grateful for the break! :)

Awesome photos @rambo. I have pretty much the exact same over the shoulder clamping kit, its cheap, plasticky but also means its lightweight.. I've none of the other extra bits though, and often struggle getting a good position with the limited blocks it came with to offset and mount the camera.

Nice work though! Epic action shot in the surf!!! :)

truly handheld.. (with no coffee that morning) non IS lenses, maybe 28mm for good footage.. I shoot "handheld" footage with a shoulder mount.. when a client asks for handheld footage they don't really know how its shot, just know they want that handheld look.. AKA "shakey cam"... I do up to 50mm non IS lenses with a shoulder support.. after that its to touchy for me .. Can't imagine doing 100mm on a micro4/3 camera unless it is a totally static shot just standing and shooting AKA not following action ect.

Rambo said "As for shooting from a moving platform like a boat, Jetski, you have to become a human gymbal and learn to keep your arms still and move your body independently, just like those break dancers do."

... or chicken! :)

@Rambo I have that same shoulder rig. I just shot some stuff on a 200mm with it. Not the steadiest footage in the world, but not jittery by any means.

@stonebat You said "Or you could wait longer and get 35-100 f/2.8 Power OIS."

Do you have any more details on if a lens like this is available yet for M43?

@Rambo "If you have to move, don't try and walk like you are holding a camera while walking, walk like you are strolling down the promenade with your wife/girlfriend" br You mean the new or the old ? lol

@Rambo, you are a legend.

+1 for the 100-300 v good OIS even on the long end

Another tele light and is a beast, a great unknown is the UNDERGROUND MC Auto 135mm 2.8, beautiful look, it seems hard to get, although it seems to be made for various mounts, mine is for Pentax and have UNDERGROUND in red, MC green and the rest of text in white.
