The new, rumored Sigma 150-600 f/5-6.3 designed for mirrorless will be about a quarter lighter than the Sports version of Sigma’s DSLR equivalent launched several years ago, according to Nokishita.
It will have one more lens element and be priced at about $1500. This makes it more equivalent of the Sports version of the older lenses in terms of performance, but between the Sports version and the Contemporary version in price.
