Is this M42-PK adapter any good?


I wonder if anyone here has used this M42-PK adapter
made by Bower (as I was told).
Is it any good? Does it still have the weak latch plate as
in Bower's previous thinner M42-PK adapter? The "thinner"
adapter is the replica of the genuine Pentax adapter.

Many thanks,

I've never seen this one myself, but looking at it, I suspect it won't infinity focus due to the flange on the lens mounting side.

It looks like one of the ones that will allow infinity focus and the inner flange will depress the A pin on M42 auto lenses - usefull for lenses with no A/M switch. I've never tried one though.
