But not as much background blur on the box art behind (which is only inches difference in distance)
Also this is slightly backed off from minimum focus distance. It's not great, maybe 3 feet. The lens has 11 aperture blades. 8 elements in 4 groups, so its a simple design with a certain look - if you like that.
