well I would never argue the photographic magic of any takumar. that goes against my most core of beliefs. a sin of the highest order in all honesty.
but I just thought it strange to comment on how small takumars are by showing a photo of one that I was almost sure was bigger and heaver than the Kmount version! you can't go wrong either way though in terms of performance. I just think the idea that using takumars because they are smaller or lighter, wouldn't be the best reasoning as it isn't always the case. that of course has no real merit in the face of all the other qualities of Takumars, especially since as you say, the difference is very little at least in a lot of equal focal length/max aperture Kmount counterparts.
