I think that review is very unfair. First off, it's done completely in the digital realm. Second off, it's being compared to a modern Leica lens which sells for thousands more! My Hektor is a very good and sharp lens for how little they cost. Who uses a 135 with a Leica anyway?!
Well, I think the comparison in regards to optical quality is inherently unfair, in light of age and cost. I don't think the review is, though. The reviewer stated being willing to overlook the lens' weaknesses, given its age and price, and validates it as a cheap alternative to the latest and greatest high dollar 135 for occasional use.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
