It depends on the light. If you are able to step down to the sweat spot of the lens/TC combo you will generally get good results, When you aren't able to step down enough, cropping often are a better alternative, and in these situations, the body often is the limiting factor yes. One more thing. The debate very often is about resolution and contrast alone. But there are more than that to concider, ie. bokeh and abrivations. Very often the lens/TC combination suffers from both. -- MaritimTim -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
