Well, that's interesting. I wonder how the 1.4 and 2x are different from the current ones? The current 1.4 is very good, optically.

1.8x could be very enticing.

It is mainly destined for the upcoming newer generation tele lenses, they should match better together.

Of course it may be slightly better than the older ones but the gain should be more noticeable with those.
