Comparing Vintage 28mm Lenses: Revisited

Three months ago I compared five vintage 28mm lenses. Based on those results I've obtained one new lens and dug up an old M42 from my archives. Here are the lenses in today's comparison, with their official designations:

• smc PENTAX 1:2 28mm 
• smc PENTAX 1:3.5/28
• SMC PENTAX-A 28mm f/2.8
• Vivitar Series 1 28mm 1:1.9 VMC Auto Wide Angle
• Carl Zeiss Distagon T* 28mm f/2.8

I didn't exactly need another 28mm lens. If you doubt that statement you can read my previous comparison of this focal length, or jog over to the Great Vivitar 28mm Bestiary. Yep, I own dozens. Nonetheless, here I am with my latest purchase, the "smc PENTAX 1:3.5/28" (to give the formal name). In this article I will provide an overview of the lens and present some photographs.
