Are Sigma now having to "get real" with the pricing of this monster? Maybe they've shifted so few of them that they've had to revise the price... I'm sure I saw it for sale on Jessops website last winter (2010), for £25000. It's now £15000! Still a mortgage-level investment, but what a price drop. ...or maybe it's just to compensate for the buyer having to employ someone to lug it around.
