canon 300 f4 vs 100-400 f4.5-5.6
Becoming more enthusiastic and serious about photography I want to buy a new lens for my canon 20D. Like to shoot wildlife.
Not having the funds to buy a 400+ mm (2.8) lens I want to buy either the:
Canon 300 f/4 L IS
Advantage: Prime so most probably sharper.
Canon 100-400 f4.5-5.6L IS
Advantage: zoom lens having 400 mm
Disadvantage: most likely not as sharp as a prime
I have the feeling that you never have enough zoom so I am tempted to go for the 100-400, which also has the advantage that it has the range 100-400.
On the other hand it would irritate me if the shots would be soft especially at 400 mm , since that I will most likely use most. (Is 300 mm f/4 with 1.4x extender sharper?)
Does anyone have advice and/or has experience with these lenses? Do you think I would miss not having a zoom (never has a prime lens before)?
Thanks for your response.
