Peaking Disappears on Zoom-in at DVinfo.net

Michael H. Stevens · January 29th, 2008, 12:58 AM

I am having a problem with the peaking which seems to make it useless and I wondered if it was general. When I get to the end of a zoom into a subject or when I use expanded focus, the peaking disappears. I thought at first it might be a back focus issue but I don't see any obvious back focus problem.

Would just a tiny bit of back focus error do this? Shall I reset the back focus in the maintenance menu and see if it helps?

I actually had the opposite problem yesterday, although not using expanded focus.

Little peaking shown until just as I reach the end of the zoom range (close-in) when suddenly the whole screen turns dark blue (the color I selected for peaking) making it completely illegible.

Here, the peaking consistently disappears when in expanded focus - I thought it was so be design. How about the others?

Could it be this: when zooming in, the depth-of-field is becoming more shallow, thus decreasing the in-focus part (throwing much of your picture out-of-focus) and peaking can be almost gone.

And there is no peaking available when using the expanded focus.

regards,
Erwin

This being so I think I will turn peaking off. To zoom in and expand with that great LCD is just fine for me and I am fairly blind (but maybe be not after tomorrow when I have eye surgery)

I find the peaking and expanded focus work great with the EX1.

I'm blown away with how well the EX1 is able to nail focus with the on board tools like peaking and expanded focus, not to mention the excellent LCD.

The LCD on this camera is just incredible.

I'm really not having any issues.

Also Peaking works off of the contrast in an image. Those images with flat or underexposed lighting will have very little peaking.
