Sigh.
Why did you buy your D90? Following your logic I'm surprised you didn't buy a video camera and only used the picture capture button on it.
What do you mean? I use my D90 Really often, Its just I take film now so I wont be using it as much, and D90 isnt quite good with recording due to no AF in LV.
Yeah I kinda figured. I saw the reviews and some said the sigma wasn't any different to the stock 18-55
If you are using it for video, maybe check out this site instead.
Canon T2i / T3i "Fast Lens" difference?
I believe you will get a better answer there since that site gears towards video instead of photography.
Lol thanks, much appreciated.
