Right behind my monitor and outside my window at a feeder w/black-oil sunflower seeds----maybe 10 ft total---We seem to get only the Chestnut-Backed variety-----I know the aluminum wire looks tacky, but we get such ferocious winds hereabouts that it's needed to keep the feeder from blowing away----used the 180L on a dark rainy day----I need to start some Macro with it------thanks for viewing!
