il peso è da favola, il prezzo un po' meno...
la qualità ottica non ho dubbi che sia ottima
La recensione riporta
“ Sharpness is excellent right out to the edges of the frame, even when shooting wide-open at f/4.5
There's marginally more color fringing across the whole frame than from the super-pricey Nikon Z 400mm f/2.8 TC VR S but it's still of a very low order and will generally go unnoticed
There's a very slight touch of pincushion distortion but, as with color fringing, it's a tiny amount
Build quality, handling and overall performance are epic so if you're in the market for a super-tele prime for your Z system camera, the smart money's on this lens. „
Insomma loro sembrano decisamente entusiasti
