    view @55m with the 150-600 Contemporary @600mm 100% I am happy :-)
  • stacked with Zerene from 40 single pictures take with a Canon Macrophoto lens (35mm/2,8). Black red gold are the colors of the german flag, that's the idea behind the pic.
  • I have a two old Sigma macro lenses with MC-11 Converter and that does not work. I think it only can operate Sony lenses with focus by wire lenses.

    sorry but if an OVF is crappy then it doesn't help either, such argumentation is useless. People like you had the same style of arguments years ago when we wanted Liveview. We never had it, I never ...
  • - stabilised view finder - silent mode - more freedom in lens design, therefore a higher chance to squeeze the optimum (mostly on wide angle designs, as seen on Leica M) - direct control of ...

    So I`ll start :-) Dear Sigma-Marketing, don´t forget us Pentax users, beside my Sigma K-Mount lenses 50/1,4 and 85/1,4 8-16 / 18-35 / 50-500 I`m interested in your new lenses. So please reconsider ...
  • So would you make Special orders to customers who didn't buy your regular stuff? Zeiss needed years to clear the shelves with lenses in Pentax mount. So we have to accept that there was not ...
