Look at the link and you will understand:
Will I have the money to buy either of these beauties? Not anytime soon. Will I have enough of a need to use these lenses every day or every week? Probably not. They are specialty lenses that would be used maybe once a month, like my Profoto ringflash is a specialty flash that only gets used once or twice a month. But still… They are SOOOOOOOOOOO nice!!!
