LENTE PENTAX M 50MM F2 MONTURA PK

A neat lens that takes superb images on par with the superb Series M 50mm lens and the rather plastic A Series of later years. I mainly use film so I don't over-process my images through any on-board digital camera technologies, and minimise any software edits that boost up the actual image.

An f2 never bothers me as I rarely take pictures that need f1.8 or lower.

I can only rate this lovely lens at 7 as, by 2020, the rear lens element (not the rear lens but the next element in) has glued-together glass and this separates after a while, giving a hazy and discordant viewing through the lens. See the diagram, above. I have one like this, and had two f1.8 equivalents that also had varying stages of what is called "separation" that is expensive and difficult to repair. Be careful not to buy one like this. Even if yours looks fine, as the years go by, this design will fail in all lenses due to the mechanics of the material used to snug the glass together. So check yours is in perfect condition by shining an LED torch up the lens to see if you have blooming haze or light discordance in that back end. Don't shine into our eyes directly and don't stare too long.
