Ok, in my quest to try and understand how the Agus, Aldus and the mini35 work, I have been gathering lenses from all kinds of places to see how this all works.

The keystone XL200 camera, has a built in zoom lens - one that works like a superzoom where you can pull the little knob on the side to zoom in (they call it tele and wide respectively). Now, after taking it apart, I noticed that I cannot see through the lens at all (up close), but when I bring it far enough back, I can see through it (although it is really small). Now, there is also a piece that comes off the lens part that exposes me to the entire lens (japan made). This lens (and the tube part that gives the zoom/tele mode) is just a piece of glass from what I gather (which is strange to me). I thought the lenses were in the tube? Anyways, to make a long story short, I am confused again on how this all works. Help and suggestion from anybody would be great!

Sean, I edited your post to activate the link. You can make your links "hot" this way:

Thanks, I already have that book marked but I am still confused. I guess it is going to take getting an actual 35mm camera and playing with it to figure this thing out. Thanks anyways,

By the Way, does anyone know who wrote that article on DOF or an email to get a hold of him/her? It is well laid out and very descriptive,

The depth-of-field also depends on the target size. 35mm creates
a shallower DoF than a 1/3" CCD size has for example. If you
where to mount such a lens directly to a 1/3" CCD you will get
a 7.2 times magnification since 35mm is 7.2 times as large.

What a mini35 and homemade adapter do is project this 35mm
image (at the correct size and distance from the lens) on a surface
([spinning] ground glass). Since this is a 35mm target image you
retain the original DoF. All you now need to do is photograph this
projected image which you do with a series of macro lenses
(since the image is a lot smaller compared to the real world so to
speak)....

I hope this kinda explained it a bit.
