spot the difference

ok, not scientific, not on tripod and not exactly the same framing.
But the same subject and close enough... all shot wide open.
Lenses in action: FA*24, FA31ltd, FA43, FA77ltd. Can you tell which one is which without cheating?

Purely looking at the DOF I'd say that...

#1 = FA43
#2 = FA31
#3 = FA77
#4 = FA*24

Now I do know that my FA43 has a harsh bokeh, but not so much at close distances. So #4 could be the FA* 24 because I know it does not have a nice bokeh in certain circumstances too.

1st is 31
2nd is 43
3rd is 77
4th is 24

PM me the answer or something. I don't own a single one of these lenses so I doubt I'd do well.

1. 43
2. 31
3. 77
4. 24

I am confident that 1. is 43 and 2. is 77, but not sure about 2 and 4 (this is a toss up... if I am going with max aperture, then 2. is 31 and 4. is 24, however, if it is just focal length, then 2. is 24 and 4. is 31).

The first and last images' bokeh is pretty bad so im thinking one has to be the 43mm and the other the 24mm

I think it goes:
FA 43mm
FA 31mm
FA 77mm
FA* 24mm

OK,
Asahiflex, Yeatzee and aleonx3 got it right.
The lenses are as follows; 43 - 31 - 77 - 24
this little experiment shows just why is 31 so valued for good OOF. Just shame I didn't have my K50 at home.... would make it more interesting

the test also tells why an F2 24mm lens isn't enough and would disappoint those who think or believe that they can achieve that magical oof look for portraits with a 24mm lens at only f2 opening.
