Originally posted by UncleVanya I would argue that the f2.8 lenses would be counterproductive. They would eat into existing F mount 2.8's and many users would already have those. The lenses wouldn't be much smaller than F mount and so in this way they can upsell. The buyer gets the F adapter for the fast glass they have and then picks up a smaller mirrorless only lens with superb sharpness (not seemingly consumer grade from the few people I have seen posting about using them so far).
Kinda on the fence on it truthfully.
One one hand at least they're not doing what $ony is doing and coming out with expen$ive ass gla$$ right out the gate that's aimed ag the pro market, and they have a native adapter that works with a good bulk of their F-mount system so at least they got some extra time to work on get the higher-end glass for the Z-system.
On the other hand they've been hyping the "Optical Performance" of the new mount so much, why not put out some fast native glass out, a couple f1.4 primes & f2.8 zooms, to show off the "Optical Performance" right out the gate and have people drooling?
