I would use it for portraits or candids.

It's a little long for close-up indoor work on a crop body, but if you're in a larger room or using FF than it's perfect for that sort of thing.

It's a little slow to AF, it also has electronic manual focusing, but it's a Magical one-of-a-kind-Lens and well worth it!

Be careful mounting the lens onto the body, as the rear glass is very close to the mounting ring and it's easy to scratch the rear glass, if mounting without looking.

Did I mention that it's Magical!!
