i dont think using the 70-300L during F1 is a good idea. It is quite a slow lens leh, considering its aperture. a telephoto f2.8 lens would be better cos singapore f1 is night race
i was using my 100-400mm f4.5-5.6 L IS during last two races, 4.5-5.6 is more than enough,with the ligths 1000x brighter than ordinary one,...:sweat::sweat::sweat:
Had the intention to get 70-200 f/4 IS as my long lens. Now gotta reconsider with the new 70-300 L. Apart from price and weight (760g vs 1050g), waiting to see how is the change in aperture spread across the focal lengths. Hoping better than the non-L.
:think:
stick to the f4 IS. If going by my DO, it is likely the 70-300 will drop to f4.5 by 100mm, f5.0 by 150mm and f5.6 by 200mm.
Not too sure why they released the 70-300L. Kind of like killing off the 70-300 DO even though the latter is lighter and shorter when locked and packed for storage. Can a lens that extends when zoomed be weather sealed?
