Just a thought about a sports event I attended. Was one of the covering photographers and almost all of them were using 300 f4 or 400 f5.6 lenses. Everyone, whether they were using nikon or canon were practically shooting at ISO 1250 and above.
With low-noise sensors these days, it seems like telephoto speed kings with f2-2.8 are seemed as bulky pieces of glass. In the past, where people were using provia 400 slides or negatives for sports events, it is understandable why big f-stop can get you the shot.
With "build in TC", thanks to FLM on DSLRs, plus the ISO 1250+ advantage with very low noise, it seems like the only reason for a fast lens is for the sake of stacking TCs. Seems like the game has changed - lenses are no longer the king, but the technology behind the camera body.
Feel free to disagree with me, just wanna share the conversation I had with two of the pros that day.
