I use a EF 600mm f4 IS L Lens. I try not to use a 1.4 Extender because of the detail losses, delay in auto focus and the loss of a couple of stops.....and if I'm down in front at Pipe I use a 400mm f2.8...If I need to be tighter, I crop.....I've compared my 600mm no extender on and cropped to my 600mm with extender and no crop, and found my cropped samples to retain more detail........the two exceptions are Sunset and Waimea Bay, there the 400mm with the 2x is "Killer"when you need that kind of reach, but, then alot of folks think I don't know what I'm talking about...and no I'm not a Cali Kid, I'm from Honolulu........
This is interesting. Thank you for the information. I have hard time to make up my mind for choice 300mm or 400mm F 2.8 with extender 1.4 and 2.0 that I plan to buy one of them in around late Jan or early Feb 2007. I talked with few pro photographers of surfing, I was told that 300mm F2.8 lens with extender 1.4 and 2.0 may be good enough for me to shot photos of surfing at Malibu, Trestle, Rincon, any point breaks and some reef in Southern California that where I live in (Oceanside) North San Diego County.
They said If you plan to shot photos of surfing in Central/Northern California and Hawaii, you must use 400 to 600mm for regular shots but sometimes, use extender 2.0 for push 400mm to 800mm like you used this at Sunset and Waimina.
Some pros said they don’t like to use extender 1.4 and 2.0 because they caused photos' quality little fuzzy, others said, use them and just little bit reduced quality but photos look still sharper anyway. 400mm F2.8 seem heavier to carry around. How can you deal with this heavier weight if you have to travel anywhere like 3rd world countries?
That's why I think 300mm F2.8 lens with extender 1.4 and 2.0 is perfect for travel because it is light weight and easy to carry around. Do you agree with pros that they explained to me?
