Samsung lenses?

Does anybody use the Schneider K/nach lenses supplied with the Samsung range? I heard that they are pretty good. Can someone give me feedback please..

They are the same as the Pentax products.
Although I don't know about the coatings if they are the same, does anybody knows?

I've had Samsung badged versions of the 12-24, 18-55, 50-200, FA35 and DFA100 in my hands to compare against Pentax versions (my friend has a GX20 and the aforementioned lenses). The coatings on the Samsung lenses do indeed have a slightly different colour to the Pentax ones when viewed side-by-side, but give the same colour rendition in photos (unlike most third party lenses). Other than that the only differences are the markings, a blue ring around the base instead of a green one and a different profile to the rubber grips (focus/zoom rings).

Amateur Photographer magazine tested the Pentax and Samsung variant 12-24 and 50-200 lenses side-by-side last year and found them to be all but identical in performance (miniscule differences being put down to sample variation) so if you can get the Samsung ones cheaper then do so!

I must have missed that issue. Those magazines are extremely expensive in South Africa and is limited to a quick browse at the local news agent. Thanx for the valuable info..
