Testing SIGMA 18-50 f 2.8-4.5 DC OS HSM with my PENTAX K30

SAM_4306

So here a simple TEST about SIGMA OS System with SR (Shake Reduction) of my amazing Pentax K30,I had found it in a store with the box coverd by dust,this is  a UNDERRATED and Almost UNKNOW amazing lens made by SIGMA ,the focal is 18-50 f 2.8-4.5 nicely sharp with a nice Price(199€) and a not constant aperture at f 2.8(50 mm f 4.5) much better than any kit lens that PENTAX can provide.This Lens has OS System that could perform well with the inner and sensor Shake Reduction system of K30.Shame on Pentax that are selling with price out of market f 2.8 lenses…16-50 f2.8 more than 1000$ what the hell are you trying to do,legal robbery?

  1. I’m surprised how well the OS seems to work with the SR. I’ve always heard if you use OS, which tends to be superior for video, you should turn off SR. Olympus has a 5 axis stabilization for a few of their cameras which is just remarkable- works with any lens.

  2. Also, I saw Hallowwen III when it was released. People in the theater were ANGRY and felt like they had been cheated. I still remember that little jingle: “8 more days till Halloween, Halloween, 8 more days till Halloween, Silver Shamrock!”

  3. Ciao,thanks for the reply,I’m very happy OS + SR doing great ,but to tell the truth if you watch closely my tests OS or SR alone could be better.Halloween III for me was great any layers of this flick are great I don’t care if there is not Michael ,I can deal this absence with Grey Suited Men or the Cochran himself..
