DoF preview with Panasonic
9 months ago

On the Panasonic bodies it is incredibly frustrating trying to compose with the macro lens at close distances because the Live View depth of field is fixed at F2.8, meaning razor thin DoF at the required working distance. I really hope Panasonic can find the goodwill in their hearts to allow the preview to be actually representative, and I won't have so much frustration trying to use their products! It is much worse when there is a breeze and the subject is constantly moving in and out of the tiny focus plane... I literally just set my aperture, roughly compose and then randomly fire the shutter hoping I will get everything I want in focus, and sharp. Honestly, this is no way to work, but without changing to the rather poorly implemented shutter preview, it's is the only way.

I guess there's no reason this can't be done... thinking of manual aperture rings...

I can't speak for other Panasonic bodies, but my GH3 has a "constant preview" setting (page 4 on the Custom Settings menu).   If you turn it "on" then the camera shoots a continuous stream of images at the selected shutter speed and aperture for display on the LCD or EVF.   This allows you to preview depth of field and the effects of motion blur at the selected exposure settings.

It's difficult to use in low light conditions because when you get into the range of slow shutter speeds it means the LCD refreshes slowly (at a shutter speed of 1/5 of a second it's impossible to show more than 5 updates per second on the LCD, obviously).  But this isn't an issue in bright light.

DOF preview works perfectly well on my G5.

Have you thought about reading the manual?

Constant Preview is available on all GH-series, the GX7 and, surprisingly, the GM1. It's a feature that ALL Panasonics should have!

BTW, Constant Preview is available only in M mode. That's reason enough for me to shoot in M mode 99% of the time!

yes its a low end camera, but in IA mode you had the ability to tab "touch defocus"
enabling to control apperture during liveview from wide open to f11

But that's the problem, it is not constant and for no good reason. As soon as you press anything else, it goes back to the standard live view. Who would want to assign an FN button to this, when it should be the standard? I don't see why having the lens at its widest is useful in any situation. Seems like the only model without this 'constant' feature.

How long have you been using a camera? and are you using Ai mode for this type of work?

I am confused by your statement, as any one who has been using a camera for some time knows that to do macro work, or to get DOF you should set the camera to any other mode  than Ai . as the camera will choose the f stop for you, and this goes for all camera bodies, not just Panasonic. Set your camera to A mode as this allows you to set the camera to any F stop even up to F22 or F32 depending on the lens that you are using hence giving you any DOF that you require

Yes! And of all things, manual mode.... you would think it would be enabled in Aperture priority mode. Is Panasonic hiring monkeys for programmers?? http://www.dpreview.com/forums/post/50053787

M mode is no more difficult to use than A mode.

If you're using one of the newer camera bodies with dual control wheels, with one set to adjust aperture, it's easier. With manual lenses and their real aperture rings, it's even simpler.

I always shoot in Aperture priority, including for macro, but even so, the Live View DoF preview is always at F2.8, regardless of what aperture I have set. This is what makes composing such a pain.

Using the auto mode isn't really suitable, but on second thought I guess it's the only choice.

I assume it goes back to f2.8 upon pressing anything else to maintain as smooth and grain free live view as possible.

Tbh I don't see why your finding this such a constraint. Set up rough framing, press DoF preview, adjust aperture so everything you desire is in focus, fine tune framing, take picture.

I do not think that this is what the OP means. If the camera defaults to only F2.8 in any mode when in LV, and can not be changed then the camera must be faulty and needs repair.

What do you mean by "it is not constant"?

What is not constant?

With my camera (G5) set to A and DOF Preview set to ON, I can adjust the aperture and see the DOF change. It works very well within the limitations of the screen size. Nothing else affects the DOF so why are you trying to change something else?

What is it that you are expecting?

You also say "I don't see why having the lens at its widest is useful in any situation" Way back in the late 60's cameras/lenses were developed to be normally wide open for viewing, focusing and metering. This was seen as a major step forward in ease of operation. Why do you want to go backwards?
