Re: Should Panasonic add a Minimum Shutter Duration setting to the GH4?

I have been using the GH4 since day 1. Honestly, it is very close to being the perfect camera for my needs. The biggest issue I have is that Program Priority mode with Auto ISO will never use faster than 1/60 of a second shutter duration if you have a wide angle prime on the camera. Here is a video that explains why we need a minimum shutter duration setting for Auto ISO in Program priority mode for both stills and video.

Even if your ISO is very low the camera will simply use whichever is faster of “1 divided by 2 times the focal length” or “1/60 of a second” in Program Priority mode with Auto ISO. If you are using the excellent Leica 25mm F1.4 lens or the 14mm F2.5 lens it will always use 1/60 of a second or slower in low light situations.
The GH4 is excellent even up to ISO 12,800. There is no good reason for it to be shooting at ISO 1600 and 1/60 of a second if it could be shooting at 1/120 of a second and ISO 3200. Even if your subjects are standing still a simple head turn can cause blurring at 1/60 of a second.
Panasonic recommends the Intelligent ISO feature instead of the Auto ISO feature in order to predict motion. However, the Intelligent ISO feature is actually even worse. With the 35-100mm F2.8 lens in low light it will often use 1/30 of a second or slower shutter duration and a low ISO if it doesn’t detect fast movement. At the equivalent of 200mm focal length on full frame 1/30 of a second is absolutely not sufficient even with the in lens image stabilization.
The true remedy for these issues is to implement the minimum shutter duration setting for Auto ISO in Program Priority mode that is found on the LX7 and most likely on the upcoming FZ1000 and LX8. This feature would be easy to implement on the GH4 with a firmware update. The problem is that Panasonic doesn’t think we really want it that bad.
Please watch the video above and let Panasonic know that they should implement the minimum shutter duration feature for the GH4.
You, that you have a Mode, which you can use to control your shutter speed, don't you? It is called "S".
