i have Canon xha1 and bought red rock m2 adaptor.i was ablr to do all the required set up.even i can see the moter image of the adaptor through the view finder of my cam but when i put my nikon lens which is 85 mm1:2 nikkor ,i cant see anything on the screen or in view finder it all black.please help.
Great video, I have the exact same set up, i've got 2 nikon lenses, 1.4 and 2.8.
But and i hope you can help sometimes i want a full shot all in focus (like the camera's own lens) but the two lenses i have seem to be shallow dof.
I don't want to take the whole kit off and use the normal camea lens as it won't have the ground glass effect, can you tell me in simple terms what lens i need to get?
Fish eye lenses are ground (constructed) specifically to give the effect. But also they are extremely wide like 8mm and 10mm lenses. Normal Nikons are not fisheyes.
They do work, I just dont know what style they deliver. Some people like Canon better than Nikon. Manual focus lenses are essential for using the follow focus (the handle/dial).
Ok I am having the worst luck with lenses with this bastard. I have a 35-70mm 3.3 - 4.5. It is for sure not letting enough light in. What kind of lenses do you use.
And I just want to say thank you, all your videos are awesome. I can now skip film school.(Seriously!)
gosh. so does a 50mm behave like that 50mm used in an SLR or motion picture camera? a 50mm lens focal length is equivalent to 50mm. There isn't a conversion factor with the M2 because the full sized image is projected onto the CineScreen.
Now the focal length is different from the fall off factor. Other Red Rock users say it's a factor of 7.2x for 35mm vista (SLR) gate lenses - so 50mm = approx 7mm (just under) on a 1/3" chip camcorder and to cine lenses it's about 4.4x. The solution to this is to stop down from wide open, zoom the video camera's zoom in enough to eliminate the edge or know your letter box (1.85, 2.4, etc) to eliminate any corners of the lens.
im new to all this, and your last comment bothered me a bit.. prime lens? fixed, can't zoom in or out? i dont get it. can't u fix zoom lens onto the M2... or what about the camera's own zoom feature, surely that will work?
Are you familiar with the standard 50mm lens for a still camera (35mm film SLR)? That is a prime lens. There is no zooming a 50mm lens. If you want to change frame size, you have to move the camera or the subject. yes?
It's suggested that you dont use zooms, and only use primes, but on the forums now, they are saying that you can still get good footage from zooms... i think i'll get a zoom and a prime.
2)No, the camera's own zoom cannot work with this equipment because it has be precisely focused onto the "imaging disc". That little picture in picture is me adjusting the camera's zoom and focus (aka "back focus"). Once that is set, I only adjust the prime lens focus. If you mount a zoom (like a 28-70mm) you can "zoom" but I dont use zooms b/c they exhibit "breathing".
One could conservatively stop at 60 ft (20 m). (30 ft is more realistic). If there is still sharp focus here it can be assumed to go to infinity. Mathematically this is incorrect but it will suffice for most lenses. Furthermore, rarely will you have a subject more that 30 feet away where you need to rack focus (applying traditional Hollywood style "studio" shooting) If the lens can focus selectively focus beyond 60 ft then you could test this further distance on the day of the shoot.
Great tutorials!About the DOF chart, how far away from the M2 focus plane do you calculate the distanses for the various lenses?At what point do you stop measuring?

A wide angle lens (smaller focal length number) has greater overall sharper focus. Nikons would be 16mm, 20mm, 24mm, 28mm and 35mm.
Long lenses 85mm, 105mm and 135mm are much more--extremely focus critical.

Thanks, wouldn't that give me the fish eye effect though?
Thanks for getting back to me.

do canon and minolta lenses work well?

Nikon F mount and Pentax K mount all Manual Focus (NO AUTO FOCUS)
Also, zooms dont work well. I use prime lenses unless requested per client. But then I explain its not a pretty with the zoom.

Is there any Magnification Factor,when using the M2. for example when using 50mm lense have to multiply by eg. 7.2 or 8 etc.
