Originally posted by mee I think so too.. plus with IBIS it could be a really nice lens for K mount.
I wonder the size and weight though.. no free lunches, I know. haha. The Sigma 150 is beefy and I can't expect this to be much different.. but maybe a little weight savings with no AF motor or IS built in?
It will be big, but time will tell. no AF will help. if it is weather sealed, even better

umm, isn’t longer focal let you be little more fruther away from subject..? dof at close up will be thin.any one who shoots 1:1 on any macro notice this. wider gives more surroundings, and narrow like this more just a bug or what ever..right?
