In addition to the issue of the image going dark (all cameras, all lenses) when looking at the DOF preview, keep in mind that you are looking at a very small image. Nowhere near large enough to really judge much detail in DOF - esp when that image is very dark. DOF preview is kinda interesting to play with, but is really pretty much useless.

There's always room to tweak the amount of blur in post processing, too. But it's easier if you try to get what you want in-camera.

How do you think that the DOF preview will be on the E-330 LCD with the live-view ?

I think it will be fairly useless. The live preview function is a view provided by another sensor. It will not give you the actual image that is going to be recorded by the camera. The live view that uses the main sensor will disable auto focus, and thus require several steps and switching back and forth to achieve focus and then check DOF. Cumbersome at best.

I thought we'd already covered DOF preview when you were asking about it previous forum thread.

You'll see this response from me concerning the Olympus E-330:

In Live View mode A (the only mode that allows Autofocus), which uses a miniature CCD in the viewfinder chamber, DOF will not be representative (mostly because of the size of the sensor), and the live view will not allow you to magnify the image.

In Live View mode B (more useful for Macros), the image can be magnified up to 10x and DOF should be representative. This mode uses the camera's main sensor, requires manual focus, and will not allow the use of the viewfinder when in this mode (it will be blocked by the mirror). Shutter release in this mode will also be delayed by approximately 1 second.

But, we didn't get around to discussing DOF preview in your recent thread asking for votes (this was is now 6 pages of questions and comments):


OK -- I'll be nice. But, you are doing an awful lot of analysis and seem to be going over issues that have already been asked about before (and answered by a number of forum members here).

Feel free to get all the opinions you want. But, keep in mind that they'll most likely be biased, including ones from me.
