Hello, After doing some research I found that used Pentax K-mount lens one can get for cheap and excellent quality. I don't have a problem with manual focus, but heard that some Pentax bodies actually show a Green LED in view-finder if focusing is correct! My biggest problem is controlling the exposure and thus the model I'm looking at should provide good exposure metering facilities that too with K-mount manual lens. Thus, can anyone suggest a good Pentax body to support such K-mount lens along with the good features I mentioned? Any help will be much appreciated. I am new to Photography and thus getting confused. Regards, Bob-A virgin photographer.
