Now doing something similar to last post but this time with the 18-200mm lens set at 200mm and f5.6 it’s maximum aperture.
The 18-200mm lens can focus much closer than the 85mm but doesn’t have that huge aperture. This makes for some different results.
Another big difference is that the colored wires used as the out of focus objects at 10″ are almost touching the lens. The 10″ is the distance to the camera body not the front lens element.

Viewfinder issues were not a real problem what I saw was almost the same as what came out in the photograph. This differed significantly from the 85mm at f1.8 where the viewfinder and photograph were quite dissimilar.
I’ve found the 18-200VR gives excellent bokeh when wide open (f/5.6) at 200mm. However, I didn’t know you could get that close to the subject at that focal length. Will have to experiment with this myself.
