As some of you know I converted a Zeiss Contax 28-85mm lens to sony mount. The pics are great; much better than almost anything I've seen from the 24-70 so far. Note, I'm speaking of sharpness not artistic merit.
Unfortunately I went to Sony Style here in Kowloon yesterday and my A900 won't recognize Sony lenses. I'm sure that the reason is the converter I've been using has shorted some of the pins in the camera. I've tried to keep it covered with paper but it wears away and now no longer recognizes sony lenses.
So I am considering buying a new body here along with the 24-70. The problem is that I keep looking at images from the lens on the a900 and the only really good performance I see is at 50mm. At both the long end and the wide end the corners are soft even at f11 let alone f8 and below that the edges soften up as well.
I really think it is much worse than the 28-85 except at the wide end where the 28 also exhibits poor resolution in the corners at f8.
Eventually I'll have the camera repaired but I'm at the beginning of a 3-4 month driving trip across the US so I'm considering buying a new camera and lens for that trip and dealing with the rest of the issues later.
But unless I can feel good about buying a 24-70 it doesn't really make sense as I think I can make the current body continue to work manually just fine. I'll need to do some work to get those pinsto stop contacting the converter but back in California I can get what I need to do that.
So show me some pics that show the 24-70 with performance nearly as good as the contax zeiss zooms and maybe I'll venture out tomorrow morning and go buy another a900 and a 24-70.
thanks,
Mike
