There are three options in this 5D4 menu i.e. Initial AF Point Selected, Manual AF Point, and Auto. I don't quite understand how the Manual AF Point works, and what it actually does. When I select this option, it does not look any different from the Initial AF Point Selected, at least from what I can see in the VF. Before I switched to AI Servo and Auto Selection AF, I manually selected Expand AF Area. When I get into AI Servo and Auto Selection AF (with Manual AF Point option), all I see is one AF point and this is no different from using the Initial AF Point Selected option. This does not make sense. I would appreciate an explanation on this.

I have a Arca-Swiss Z1 dp monoball head on my GT3542 tripod but I am looking for a lighter tripod for trekking. I am thinking of getting the GT1532 but I would like to transfer the Z1 head to this tripod. Does anyone know if this head will fit the GT1532? Thanks for the inputs.

<p>I am in the midst of preparing some artwork for publication. I saved an image in TIF format at 1200 dpi resolution. When I checked the resolution of the image by right clicking on it and selecting "properties", the horizontal and vertical resolution is at 1200 dpi. When I open the same image in photoshop and select image->image size, the resolution shown is only 300 ppi. Why is there is a difference? Thanks for any inputs in advance!</p>
