I shoot with a Canon 400D, and I absolutely love to shoot people and closeup head shot portraits. I have been wanting to invest in a good portrait lens. Someone told me to look into a 35mm 1.4, so I did a little reading and read somewhere that it is the lens that takes the sharpest (tack sharp I think it said) portraits of any prime on the market. Of course, another article claimed it was the 50mm 1.2 I know every lens has its pros and cons, but I would really love to get one that will make me feel I've made the right choice. I do know that both of these lenses are high quality prime lenses and shoot good images, but I do not want to center on someones nose, and have it start to blur around the outside of their hair or on their chin. I would really love a lens that takes tack sharp photos, and these two are close to the same price, and I know they are both excellent primes. If anyone is able to help with some experienced advice, I would truly appreciate it.
