[QUOTE="Horoscope Fish, post: 443717, member: 13090"] Your math is correct but also bear in mind there is a direct relationship between aperture and depth of field to be considered. While it isn't necessarily difficult to focus at f/1.4, it can be difficult to get your subject in good focus, particularly when the camera-to-subject distance is short. This is because depth-of-field depends on the camera-to-subject distance and when you are close to your subject, the depth-of-field will be shallower than when you are further away. I have a pair of excellent f/1.4 primes but I very rarely shoot them THAT wide for that reason. Just my two-cents of course... [/QUOTE]
