Hello, I have a problem with my Olympus OM-D and the Panasonic 12-35mm lens. When taking picture by using single target AF I notice a big frontfocus which gets worse in the long end, 25mm and 35mm. AT 25 and 35mm I am never able to get any charp pictures when shooting subjects at a longer distance; I validated the frontfocus by chart tests. It doesnt matter if I only use IS, or only OIS with longer or shorter shutter speed; Interestingly with smaller aperture the frontfocus gets worse. Its even strange that I tested 2 different Panasonic 12-35mm lenses at two different Olympus OM-D bodies, each setup of OM-D and Panasonic lens showed the big frontfocus. I checked out these setups where I encounter the frontfocus problem: 1. OM-D body with firmware 1.5 & Panasonic lens 12-35mm with firmware 1.1 2. OM-D body with firmware 1.2 & Panasonic lens 12-35mm with firmware 1.0 Both setups show the same frontfocus problem. When mounting a Panasonic 20mm or a Panasonic 14-45mm to the OM-D bodies the pictures are fine and sharp - no problem at all. I am very curious as I have the same error with two lenses, so I would be interested if anybody else has similar problems with the OM-D and the Panasonic 12-35mm. As this lens is new I wouldnt like to have it repaired and I would like to know if there could be a common problem here. Thanks!!
