Interesting you're bringing up Toyota. Due to a huge media campaign, everybody "knows" how much of a deathtrap their cars are.
Of course, it's all fiction - Toyota isn't any worse than other manufacturers, some of which had much to gain from all these scandals. Even fake "science" was deliberately used in order to "prove" the unprovable - it didn't work.
And now, we're close to find, well... that they aren't any worse, their cars are as safe as other's.
Would we find the same about Pentax? That they aren't worse, their cameras are not junk - but actually quite capable tools?
Fortunately, we don't have a "professor Gilbert"; but it's not the first time I'm hearing about a class action. Is our cameras that bad?
Well, as a Pentax/Toyota owner, I know the answers
But do you?
