The first time I used this lens was on a wedding shoot. I read some in-the-mouth advice somewhere that said every photographer needs a 50mm prime lens to be happy. So I thought to myself "I'm every photographer!" And plopped down the $300+ for this.I was beginning to regret the decision until I used this puppy.Pictures so crisp and clear and beautiful came out of my camera that day. Pictures that need no sharpening, no photoshopping, no curves adjustments or contrast adjustments. Just honest to goodness dead sexy clar pictures.I was so happy with the pictures that I composed a poem about this lens on the spot! It goes:Oh I think that I shall never seea lens so ripe with clarityThen the 50mm which sits abreastUpon my camera's lovely chest.I now don't mind 'walking around' more, or ditching a zoom lens. This lens is Empyrean.
