Question: Does the XCD 45 f3.5 Hunt as Much as the XCD 45P

[rollsman]

I like the 45P but it seems to hunt before it locks in AF.  Does the same thing happen with the XCD45 3.5 Lens
  Thanks

I use the 45P as my main lens and hunting has never been an issue. It does it occasionally, not very frequently and then I turn to MF (always on MF and use the AF-D button, so it is quick and easy). With magnification on, MF is a piece of cake. As always YMMV:)

Thank you. I will try it

Autofocus works best with all of the XCD lenses (including the P and the V series lenses) when the light is strong, when there is reasonably high contrast in the subject, and when the lens has been roughly focused manually prior to engaging autofocus (set the camera in manual focus mode, roughly focus, then engage autofocus with the AF-D button.

I own the XCD 45/3,5 and have twice rented the XCD 45P/4. I have not observed a significant difference in the autofocus behavior of the lenses provided that the current camera and lens firmware is installed on the X2D.

For my work I prefer the XCD 45/3.5, but I can readily see the appeal of the XCD 45P/4.

Hi Bob, Thank you.  So I should put the camera in M focus mode and use the AF-D to AF?   TY

[Bob Foster]

Yes.

Quote from page 59 of the X2D Manual v1.6:

"For users who prefer manual focus control but would like the benefits of autofocus, one method is to use the AF-D button for autofocus single. Align the focus point with the subject and press and hold the AF-D button. The camera uses the AF system to set the correct focus and reverts immediately to manual focus control when the button is released. In this case, users can recompose the picture. There is no need to hold the shutter release button to retain the autofocus setting."

An exception is when using a XCD V series lens when manual focus is enabled with the push/pull ring on the lens. This disables the AF-D button.

Hi Bob, thank you.  Just a quick question. I use the Rear AF-D button on the rear of the camera for AF.
 Do I have to Hold the AF-D button in after its focused while pressing the shutter release button? Thank you

[Bob Foster]

In manual mode,if using the AF-D button, you do not need to continue to hold the AF-D button depressed once focus is secured. The lens simply reverts to manual focus when the button is released, No further focus adjustment is made upon release of the AF-D button.

At present, in manual mode, once the camera has successfully completed an autofocus cycle initiated by depressing the AF-D button, no further adjustment to focus occurs if the button remains engaged.

In short, with the lens and camera firmware available at this time, it makes no difference if the AF-D button is held or released prior to making your exposure.

When handholding the camera I usually keep the button depressed after focus is secured using the AF-D button. My right hand grip on the camera is lighter than many photographers use. Through experience I've learned that for me the small amount of pressure required to activate the AF-D button, or applied adjacent to it if I'm not using autofocus, yields more "keepers" per session. YMMV depending on how you hold and support your camera.

Bob, thank you much. That really helped. Dennis
