[QUOTE="Ruidoso Bill, post: 40722, member: 753"] The difference between f2.8 and f3.5 is 2/3 stop. That can make the difference in shutter speeds of say 1/125 and 1/90. Your D300 does a pretty good job at increased ISO and unless you are way high it does not effect sharpness rather it will introduce noise. If possible, use a strobe to throw more light on the issue. Another thing to keep in mind is most lenses are not at their best at the min/max of either zoom or aperture. A 2X teleconverter will also double your minimum f stop (2.8 = 5.6) so no joy there and also you'll need to check which lenses are compatible with a teleconverter. Low light is always difficult to deal with. Fast glass is helpful, the D700 sensor is great at lower noise at high ISO, even the new D7000 is good at higher ISO. There are alternatives to help but they all cost $. [/QUOTE]
