We tested it with the camera gain at the lowest setting of -12dB with the limiter off. It has excellent low THD+N and a very high signal to noise ratio of 78dB at the maximum -29dBu input level. What is even more impressive is the frequency response of 70Hz to 20kHz (-3dB down points). This is where most DSLR cameras suffer – usually dropping off at 140Hz or so. The limiter works remarkably well at avoiding clipping with hot inputs. With the limiter on the S/N ratio drops a bit to 72dB but is still excellent. However, the frequency response improves to 30Hz to 20kHz which is remarkable for a DSLR camera.

Here is my first go with the GH4 time lapse features.

@azza_act In "1-Area" AF mode, I still see the box when switching to MF on the GH4, however the aspect of the box changes from a square to a rectangle that has slightly more width than height.

azza_act

Thanks guys, do you still have that box in manual mode too? With my gh3 you don't. When you guys have you gh4 in manual mode do you have the box on the screen all the time like mine?

I have mine set for a small + and like it that way. During Video recording, I have my GH4 set for touch screen. The + is the main focus point. It also effects the light metering. When I touch the screen a small set of squares or one larger one will show temporarily. Then they fade away leaving only the + where I moved it. Without that showing, I would not remember to move it when my main subject moves. i.e. The Pastor at our Church often moves from next to the Projector Screen to next to a Chart on an easel. When next to the bright Screen, he will become very dark unless I move the focal point and sometimes I need to move it to the unlit Chart to make it easier to read.

I think you can alter the "box" by changing the AF mode from "1-Area" AF to something else. For example, you can turn the "box" shape into a "+" shape if you change the AF mode to "Pinpoint." But that is using a functional change in camera operation to achieve a change in the display. I'm not sure if you want to do that?

I would guess that the closest you can come to a similar AF function with a different display is the "Custom Multi" AF function and set a similar area to the "1-Area" AF mode.

I hope this was helpful.

@caveport Looked in the manual... No luck. This box is in every mode too, I understand this is a focus function but I don't won't it on my screen all the time. Tried every setting in the cam to try to turn if off. Has been on right out of the box. Never had this with other GH cams. Thanks

caveport

Maybe switch to manual focus mode? Or you could use the GH4 operation manual to find the answer. The box is showing the focus area used on the lcd touchscreen.

azza_act

@v10tdi how to turn off the auto focus function so as not to get this 'box' showing all the time. Thanks!

v10tdi

Do you mean switch off the autofocus function? Or something else?

azza_act

Total noob question here but does anyone know have to switch this off? Some sort of auto focus thing (circled in red) Cheers

@izash What fps did you film your anamorph videos in? I'm waiting on Panasonic to unlock the new aspect ratios in 24fps. I haven't even updated the firmware yet until I hear more news
