Hi,
My take is that the Hasselblad H-series may have a pretty good focusing accuracy. I don't know, as I don't own a Hasselblad H series camera, but users seem to be happy and it is about the only AF-system Diglloyd has not complained about.
My impression, based on data from Lens Rentals, is that older AF systems were not performing on par with manual focus based on magnified live view, although it seems that late generation Canons (5DIII and 1Dx) are focusing almost perfect when combined with the latest lenses.
I am mostly shooting at f/8 (or so), so AF is seldom an issue for me. Still, whenever I can I would use magnified (11X) live view for exact focus.
Best regards
Erik
I was meaning the camera should not make you have to, no cast against your ability
Hard to believe the H1 system is from 2002, no doubt firmware has tweaked it over time, mine is an early one being a Demo on the splash screen and nails focus reliably.
