hi.. i reckon you are using the 20/1.7 II.. how's does it compare to the 17/1.8 when it comes to focussing in lowlight?.. i still can't believe that Panny made no improvements over the AF..
Ya, u r right with the 20/1.7II being used. I have the 20/1.7 MK1 too. Comparing MK1 and MK2 I saw no noticeable improvements coming to Focusing performance (AF speed in general ; whether in low light or others)
Like u , I found it hard to believe Pana didn't make improvements to the AF speeds but sad to say , facts r facts.
Pictures are still as sharp and of course , the f1.7 is great coming to creating creamy photos but if u painted both models in e same colors . I wouldn't be able to differentiate either by performance but that's me as a enthusiast not an expert.
If u r deciding between Mk1 or Mk2 , honestly I'll say go for the Mk1 as I don't see it as being value for money paying $100+ more for a nicer finish and a metal mount. The Mk1 is by itself a more than capable lens and I'm sure users will stand by it until probably the Mk3 appears haha.
But I'm sure there will be people willing to pay the premium for the nicer finish of course.
The 17/1.8 wins by AF speed, and it's by a margin which I can feel. However sharpness wise , the 20/1.7 does slightly better if u r into pixel peeping. I find the snap manual focusing on the 17/1.8 useful so it's a plus for me though it makes the 17/1.8 slightly thicker than the 20/1.7.
the GX7 w/ 14-42 kit isn't available yet but I hope to see it locally soon as US wise, this kit has dropped around USD100 since launch a few weeks ago.
