yeah, i agree, i have been sloppy when cleaning in the field, all that dust, water drops, or tiny leaf stuff normally gets blown out with my breath then rubbed on with the ends of my shirt, guess i could do a better job at that. thx for the lens replacement idea, i'll look into it and see if bushnell can help, its a less expensive idea i guess, but those bushnell HD's are on sale right now with cabelas, plus a 20 buck certificate, i kinda want a 8power, my ten is abit much for woods stalking.
