Huehue, at least i’ve the time to release ma nu gadget. Actually, it came to me in the end of this year at December..but because stuck around in office and had a lot of journey 
this post shut-in in ma database.
I’ve got this lens from ma broder in Gresik. A Tamron lens with macro features and optimal until 15 metres to zoom out. Its focal length came from 70 until 300 mm..huhhuu,long enough to make a snapshot in swimming pool 
Besides, i’m very interesting with its built motor to make focussing object became more easy use autofocus indded. When still use Nikon 80-300mm G AF (G series without autofocus motor), i always worried for made a mistakes in focusing object see here in ma last post
But with built in motor in Tamron, those problem slow but sure, had been overcome .. Although, i keept learn to use manual focus..cos in the real event, auto needs much longer time to focussing an object than manual.. But will see
