I can remain for ages watching a master operate a push pull at a match.

I have owned the canon 100/400 version 1 for over 10 years, granted i never took it out in very dusty locations. when i was zooming in and out I never made the adjustment with very fast motions and never had one bit of dust being sucked in due to the vacuum. last year i sold it and bought the new canon version 2, granted the quality is so much better but i hate it! the reason with the push/pull my left hand always had the lens supported and never had to remove it through out the full range of travel where as the twist to zoom in and out there is way to much travel and you have to rotate your wrist or use fingers either way you loose the support when finding and tracking your moving subject. If canon came out with a new version with push pull I would sell ver 2 in a heart beat and buy the new version

I’ll trade you a MKI for your MKII and we’ll both be happy
