Look, the reviewer obviously hasn't read the commentary on this website regarding the lens because quite clearly, without autofocus, this lens is not worth $4000 and nobody will buy it without autofocus, even if it is the sharpest lens since the big bang.Nobody will buy it? Leica's entire M lens line is manual focus and in the price range of $1,500 to $11,000. They sell as many as they can make, so photographers certainly do buy expensive manual focus lenses. Not every photographer has the same needs, or the same budget.
"as many as the make" indeed, there's ONE guy putting them together. But the Leica people have a completely different patience than Canikon people do. I used to work at a shop were we sold Leica and if a lens had to be serviced 3 months was FAST, and 5-6 months the average to wait, lol. And here their 24 f1.4 is 8400 usd
