K-5 MF lense issue

I don't know if I am the only one here who has ever had this problem, well, i'll give a little info on the situation here.

I have rather.. Not so great eyesight, and I use a lot of older MF lenses, so I got a magnifier, works great, but I always have a hard time focusing lenses to get them to be sharp, I have the superimpose AF setting engaged on my K-5, and many people here have said to use the "Catch in focus mode" which is supposed to make the shutter fire when an object becomes focus?

Well, the problem I have, is with this engaged, no matter what I do, I cannot for the life of me get it to fire without pressing the shutter release button.

I am using full manual mode with an old Ricoh lense and an old Sigma lense.
Any ideas as to what is going on and how to fix it? Thanks!

If it's an all-manual lens, I think it will only work with the center AF point, though I'm not 100% sure on that. Here's the guide in any case:

",,, no matter what I do, I cannot for the life of me get it to fire without pressing the shutter release button."

Doesn't the shutter release have to be depressed while the subject is in focus? i.e. you can't press the shutter release, take you finger off of the button, and wait for the subject to come into focus.

Correct!

1)You press the shutter release and then turn the focusing ring while you keep the shutter release depressed all the time.

2) On a K-5, CIF will only work if the lens mount is conductive (: bare metallic without anodizing/paint).

As Adam said, I have experienced that with most all manual lens the focus assist is often inaccurate. This is also sometimes the case w my a50 1.7, but not as often.
Another possible reason (if you are getting out of focus shots even if focusing without focus assist) is that you may have accidently hit the diopter setting on the viewfinder. Make sure it is zeroed if you are using glasses or at the correct setting of you are not using glasses.

this happens to me a lot - it's perplexing until I check the diopter slider....

The CIF is simple to use as described above. AF.S, center point, manual setting. Hold trigger down and rotate focus. Works like a champ.
