The new Skyport Speed does NOT work at any higher sync speeds with LS lenses/cameras than its predecessor did. For now it seems that if we want 1/1600th sync wirelessly, the only solution is the newest Profoto AirSync unit (which incidentally only allows wireless synch to 1/1500th). http://www.profoto.com/products/profoto/accessories/sync_and_remote_devices/air-sync
The Skyport SPEED unit does allow for faster sync with FOCAL PLANE systems in newer DSLR's up to 1/250th where the prior unit was limited to 1/125th IIRC. Also, effective working range is DOUBLED over previous model when using SPEED mode. There is also some improvement for use with smaller P&S cameras: http://www.elinchrom.com/products.php
