La plus grosse société US de location d'objectif vient de rendre public les déboires qu'il sont eus avec les objectifs Sigma ,particulièrement les 150-500 : je cite :
" In the last year, however, things have gotten much, much worse. One third of the Sigma 150-500 and 120-400 lenses we bought were defective out of the box and had to be exchanged. Several more broke during their first and second rentals. New copies of other Sigma lenses showed up with high defective rates out of the box. Repairs have become even slower and now even our routine in-warranty repairs are being refused and billed as ‘customer damage’, even though we’ve never rented them out, simply tested them."
Prudence donc .
