這個人拿來接5D,把100/2稱為他用過最棒的鏡頭:

"I don’t think I’ve ever seen a lens this good. It offers bitingly sharp detail across the field even wide open at f/2, stunningly beautiful bokeh (out of focus rendering), unusually lifelike color rendering, and an eye-popping brilliance that makes images jump off the screen. Unlike lesser lenses, there is no trace of uncorrected “haze” (spherical aberration, color fringing, coma, etc). Images just have a “zing” not seen with other optics. The ability to shoot at any aperture for the desired effect, rather than worrying about less-than-optimal optical performance at wider apertures is a major plus with this lens."

"Run, don’t walk to your local Zeiss dealer or online store and get this lens now. Although my copy is a loaner (demo), I’m not planning on sending it back; I’ll be purchasing it."

這個人好像有全系列的Zeiss ZF鏡:)
