How to tell if an objective is able to take about Photography?

If you are looking at specific aspects of the target, how do you know what so close that the camera can be at the same time get a clear shot? Does this have to do with the focal length? I am thinking of buying a 70-210mm telephoto to do macro photography with a Pentax K1000 (and soon, a Pentax ist DS2). May this lens work well for my needs? To give you an idea, the type of picture I love to do is like this: http://www.flickr.com/photos/baltic86/2811077371/ My current goal is simply not capable of that kind of thing.

There are two specifications for searching. 1. Closest focusing distance. This is the distance from the film / sensor plane to the subject, as close as the focusing lens. There are lenses in the range of 70-210 when measured in feet. The closer you can focus, the best plan that can get shot. 2. Reproduction ratio, or sometimes appears to increase. This will be a number like 1:4 or 1:2 or 1:5. A true macro lens is 1:1, ie, the issue is the size of life on the film or sensor. A reproduction ratio 1:04 indicates that the subject 1/4th life size. 1:1 is better of course, but it may bring very good shot 1:04 after printing to 8×10. I am not familiar with the specific goal you mention … I'd say if that will do better than 1:4, maybe less. Once you get that DS2 * er, get a real macro lens to add to your computer.
