Len/ Body Inconsistancies?

[Roosta]

I have recently acquired a 1DMk2N and 16-35mm L f2.8 + 24-70mm L f2.8 lenses.

I found that the above lenses seemed to miss focus slightly, and I needed to override the AF to finite adjust with manual focusing ring. But, on my 50D, it's spot on. I know my 50D has a micro adjustment feature for lens correction for focus, but the 1DMk2N does not (That I can find anyway)

I used both my 'new' (Second hand 'new') wider L lens at a wedding for a good mate on the weekend on the 1D body and found myself having to correct the AF with manual focus ring quite allot. I did try both multi (36 spot from memory) and center focus spot only, both with the same results. The wider of the two lenses 16-35mm L f2.8 was the better of the two, but at or around most open aperture it seemed to struggle as well, shallow DOF maybe?

Has anybody had similar happenings?

I also used my 70-200mm L f2.8 that day on the 1D body and it was spot on.

Throughout the day, I used AV and M modes, adjusted ISO and Shutter as per lighting required and adjust AP in AV as needed. I was using mainly wide on AP or close to, to get a shallow DOF.

I have not made any adjustments to any lens on the 50D.

All shots taken through the viewfinder, no mirror lockup used.

I did find as the day wore on, and the natural light source faded, this seemed to improve, the focusing got sharper. We went to the Burswood Casino for an after party and on the balcony looking due west, setting sun and I was using the Bride and Groom to block the fading sunlight (Backfill flash) the focus is spot on and the shots are sharp as a tack. Not sure why this is, during the wedding 11.00am (Held at Perth Zoo) the natural light source was blocked from over hanging trees, so we had inconsistant light and shadow over the Bridal Party.

I can post some shots tonight with all EXIF data attached and no PP if this would help? Probably just me, but I would like to re-assure myself. In the Formal Forum, there is a B&W and Colour image from said wedding.

Cheers.
