Though my blog named "40Lim" it's not just about this lens, no-no-no :)
Don't know exactly why, but I like to name my blog as it is - 40 Lim. Actually Pentax Da 40 Limited was the very first of my kinda serious lens for Pentax. Like it for it's sharpness and color rendition. But in first place for it's awesome compactness AND sharpness/rendition.

Well, all things gets broken. My 40Lim some day appeared to be blurry in center, sometimes better, sometimes worser. So I decided to take it apart and readjust those screws, I know, are couse that.
Not so simple. Firstly I have ordered on "flebay" screwdrivers of JIS tips, that was Moody's instruments.
It was Ok to unscrew all the bolts from the front side, but I still have trouble with one on the bayonet side. Have to get some extrcator to get rid of this nasty screw. But extractor should be of size about 1,5-2mm. Have no idea where to get it from... So I have reajusted helicoid fixing from the front side. It seemed to be fine for a while. But now problem is back. I have to get lens disassembled in full, from the bayonet side to fix it completely. I think it's loosing of screws cousing the blurryness.
