If a lens speed reads f3.5-f5.6. What is the optimum f stop you should set on your camera or does it matter?

That's the max. F/stop for the focal length of your lens.. 18-200mm 3.5/5.6 equals a max f/stop/aperture 3.5 at 18mm and 5.6 at 200mm has nothing to do with camera other than your camera is limited by the f/stop of the lens that is on the camera at the time. .. set f/stop to set depth of field, light, speed, ect.. Maybe set camera on Aperture priority for the day and see how it affects your light, background focus, ect.. The more you experiment the more you will understand.

I would say to obtain a sharper photo I would use around f-8 which is know the typically sweet spot of the lens. Typically if you want the background to be out of focus/blurred, use the largest f-stop. To get the greatest depth of field use the highest number f-stop (ie f-22) Arnold

To know what F stop you should be using and why I'd suggest picking up a copy of Bryan Peterson's "Understanding Exposure"

The middle ground is the sharpest of any given lens, f7 -f11 will produce THE sharpest images.
You would be hard pressed to tell the difference between say f11 and f16, but there would be a noticeable difference between f3.5 and f11.
People call it the sweet spot of a lens.
I hope this is sorta what you were looking for,

Thanks to all who responded. Your inputs help a lot. I'll experiment.

And please, along with experimenting; check out the book I suggested...it will answer your question and give you a "reason" to take certain shots certain ways....trust me.
If you want to have a small taste of what I'm talking about...check this out.
