I have G16, G28, G45 & G90. I found that every len in large aperture, the focus not accrately, G90 especially. May be I don't know how to focusing. please help me!
Make sure that the focusing indicator are in the middle position (rather than flashing on both side) before you shoot, and remember the golden rule "Lock the focus probably before re- framing". The shutter of G2 is two-staged, press it half the way to lock focusing, then press it all the way to shoot!
For the 90mm lens, may I remind you of the extreme shallow DOF for a 90mm lens at f/2.8 and esp at short range (> 2m), you should know how seriously would the picture be affected in case the point of focus locked worngly or with too much body movement during re-framing...........
For once I performed a simple test on my G2, the value of the digital range finder confirmed accurately with the object distance that I can measure (with the film plane mark as the reference, and error was found sometimes to be not more than 1-2cm)
