The low lights capabilities are great with the 1.2, but you have to remember that 1.2 is a very shallow depth of field, therefore you have to keep the object or subject pretty far away to get it completely in focus

At 1.2 you don't get much depth of field, so if you miss the focus then you've missed the picture.

(depth of field gets very shallow and it's hard to keep kids sharp when close

I love it wide open, that beautiful shallow depth of field where only the eyes are in focus and the rest drops off

When taking portrait shots a shallow depth of field and sharp focus abilities gives you amazing subject focus and adds a very professional, sharp, and unique picture quality than that of a point and shoot or wider angle lenses.

The shallow depth of field can be used to make your subjects pop.

we used this lens for hdslr video and while wide open with very shallow depth of field means we had to make sure we focused carefully, it was worth it

This lens gives you excellent depth of field control, excellent bokeh, and gives super sharp focus.

The razor thin depth of field (DOF) makes AF challenging compared to slower aperture optics

This lens is not difficult to use because of the shallow depth of field and if your photos are not in focus, then you need to micro-adjust it

Shooting at f1.2 produces very good images, but very shallow depth of field, so be careful with recomposing shots.

However you must pay close attention to the focus point because the depth of field at 1.2 is very shallow.

The depth of field is not difficult to get used to and close up

I love it wide open, that beautiful shallow depth of field where only the eyes are in focus and the rest drops off

also).Many users may have problems using the lens stopped wide open or nearly wide open, due to the EXTREMELY shallow depth of field, and this is an important consideration

It's shallow depth of field and the results of this effect are simple amazing

This is not the fault of the lens as depth of field becomes extremely shallow and the pictures will come out almost "hazy" do to extreme bokeh

I love the super-narrow depth of field, too
