Many have asked me if the Z 1.4x is “worth the price?” Oh hell yeah is always my reply! At the moment, we only have one lens we can use it with, the Z70-200f2.8 but man, what a killer combo. I’ve photographed landscapes, aircraft, wildlife and yes, even macros with it and love it. I love it much much more than the F mount equivalent setup. Does it work with F Mount or FTZ Adapter – no. Does it vignette – no! Does it slow AF operation – not in the slightest! Does decrease sharpness – not even! Do I highly, highly recommend it – OH YES!
