As soon as I had installed the free software from Sigma and watched simple to follow tutorial videos, my Sigma 150/600mm was reacting a lot faster after a couple of software updates. The customisation feature is also a must. Total must have if you own a lens of this quality and you want it to perform at its best on every occasion.

Would recommend this to any one, very easy to use, the way it is set out any one can use it, cannot go wrong with this, and it makes your lens a lot better to use.

This is a great addition for my Sigma 24-105 And Sigma 150-600 contemporary. 150-600 was not sharp at 600 mm and was back focusing at 150 mm. Now pin sharp results.
