The Fujinon 4k Premiere Zooms are some serious pieces of glass and steel. There’s a reason why these things go for $90,000 each – ’cause they’re worth it.
Now bear in mind, these aren’t for all situations. You have to be doing essentially studio style shooting, on sticks or dolly and want that flexibility to change focal lengths and not require more light than T2.6-2.8ish. But that being said, if you’re in that situation, some might argue that these lenses are actually sharper than even Master Primes. I’m not joking. Take a look at what Claudio Miranda has to say about them (they had 8 of ’em living on the set of “Oblivion”) and you’ll know. When it comes to big heavy zooms, these Fujinons are no joke. They’re serious lenses for serious application, and they don’t mess around.
