12. GH1 1st test Sigma 28mm 1.8 + Nikon 50mm 1.4
3 months ago
GH1 1st test with Sigma 28mm 1:1.8 + Nikon 50mm 1:1.4
First test with fast Nikon lens.
No CC
Shutter : 100
720P 50fps to 25fps with Premiere CS 4.1 (native editing)
Duration : 4mn
It's great working with fast lenses for the DOF, but hard to focus and hard to shoot with the 50mm (100mm on GH1). It seems I have more light with the 28mm 1.8 than the 50mm 1.4.... Can someone explain this to me ?

When will the GH1 DSLR bundle from Zacuto will be available ? Will it be with follow focus ? Thanks
In a couple of weeks we will have the mounting frame to attach the Z-Finder to the GH1

As many people know, movie camera lenses are rated by a T-number instead of an F-stop.The F-stop expresses the speed of the lens on the assumption that lens transmits 1OO% of the incident light. In reality, different lenses have different transmittance, so two lenses with the same F-stop may actually have different speed. The T-number solves this problem by taking both the diaphragm diameter and transmittance into account. Two lenses with the same T number will always give the same brightness.
Love the footage.
