lol then he will shoot in complete darness

no hard feelings amlan
I am really upset with 150-500 results...I had to bump up the ISO to 800-1000-1600 to keep shutter speed to 1/500-1/1000 and pic quality become bad.
All those wonderful pictures we see online for test or drool purpose are generally taken with full frame DSLR where ISO 1600 dosnt effect a bit of pic quality.
That brings me to a situation where I can either replace my D7000 or sigma 150-500 ...I have not decided yet..just saving for now
