Hi Voytech,
How is that 24 mm Makinon? I have 2 "$5" Makinons and they both work fine.I took lots of shots with the 200/4.5 last summer .
I have a "Magnon" 35~70,dropped and broke many years ago.
I found that this brand name may be localized to New Zealand and is same as "Ozunon" and "Toyo/Five star"
So I got a cheap Ozunon that had a destroyed coating on rear element.
Pulled them both apart and made a good one which seems to work rather well;
It is a one touch zoom with zoom by push pull and focus by rotation.
I also sliced up the wide rubber grip and used it to repair 2 other lenses that had deteriorated grips.
These off brand lenses are metal/wellbuilt/repairable. The Magnon seems to have lot less elements that the equivalent Pentax.
I took close ups at f5.6 to compare it with a PKA 50 mm and the difference *** jpg at 200 % zoom on Picassa was mostly just focus error.
This shot I tried to take with SMC 24/2.8, but was unable to get all that white lettering sharp enough across the frame.
So I stood on a chair with a SMC 55/2. at f8 ( Its me, not the lenses !)
