I hate that I didn't buy this lens sooner. It's a perfect match for the Sony A7(r)(s) II series of cameras both old and new and I'm absolutely in love with it.
The lens is only F4, but I would like to think a lens like this would be used mostly by landscape or architecture photographers where wider apertures would not really be needed. But for those occasions when you do need the lens in low light and are going handheld, the OSS saves the day.
There are a lot of things I love about this lens, and very few things I don't like, making this lens one of my favorite, go-to lenses with the Sony A7r II.
