Sharpness of DVX at DVinfo.net

Milosz Krzyzaniak · June 15th, 2004, 11:20 AM

Hello

Some time ago I visited a site on which there were some pictures comparing DVX100 and PD150 60i and 30p modes in moderate light situations. Can somebody recall the URL of this site?

Now let's get to the point. Closer look into those images indicated to me strange feeling: DVX100 image looked considerably blurish while in interlaced mode comparing to PD150. And, after switching into progressive mode - magic! Incrediblee sharpness, even more details than PD.

What's the problem with the interlaced mode through?

I noticed that the DVX100A has focus hunting problem. Try swithcing to manual focus and it'll be as sharp.

The Sony performs better in auto-focus than DVX

but it's really tough to manual focus on the dvx.

The DVX is the easiest camera to manual focus. The focus ring acts like a precise, direct linkage, rather than the servo-motor-control rings on other cameras.

I can't seem to get it pint-point accurate. I zoom in, say to the nose or eye, try like crazy to find the sharpness, but in the end, give up and switch back to auto focus.

Really? Hmmm. Try opening the iris to maximum open as well. I usually zoom in to full, pop open the iris, and can grab a very sharp image in just a few seconds, then stop down and zoom out.

I've usually found it really easy to get a nice crisp picture, and when you zoom out and stop down, the DOF takes over and ensures you're getting a sharp subject.

Perhaps it's the relatively short maximum telephoto that's not helping you get as precise a "pop" in focus. The longer the telephoto, the shallower the DOF, and that helps find the "exact" focus point. Do you have a 100A? The EVF DTL peaking feature should help you find the exact focus point even more on the 100A...
