Which creates two potential problems IMHO. First is that it is a time consuming and for me frustrating process to drag a tiny window around trying to find the exact spot where you absolutely need critically sharp focus. So zoom in partially, move the window, zoom some more. I am glad to have the capability, I will probably use it to advantage in macro applications, but it will take quite a bit of practice before I am comfortable with it. The other possible issue is that all of this button pushing may well joggle the camera unless you have it locked down to the max on a rock-solid tripod. The movement of course will mean that you need to start over… One aspect I don’t care for: I would like to be using a mix of autofocus and manual. So if I lose my way while searching for the key point of focus, a quick tap on the AF button will give me the camera’s focus solution to start (over) from. Kinda like the green button will get you back to the programmed exposure solution. However, the LV focus-peaking mechanism doesn’t seem to remember how far I was zoomed or what portion of the scene I had under the zoom window. So the AF-button tap takes me all the way back to the full-view start point. I would like an option to have the zoom information retained in memory until I tell it I want to go back to start. Like happens now if you zoom in during image review, then advance to another image. There may be such an option, I haven’t found it. stan -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
