I'm not too sure about other cameras but I recently purchased an Olympus E-420. I used to have an old Pentax *Ist D (freaking love that camera) with a Tamron 28-200mm lens with manual aperture, focus and zoom rings. Now, on these new Olympus lenses (and it seems to be on other camera lenses too) there's a digital focus ring. There's no measurement of distance on the focus ring, no maximum focus, no minimum focus. I can keep turning the ring even though it's already at infinity. The reason for my semi-whinge post, is that it's starting to drive me crazy when it comes to manual focus. I have no idea where I am in the focus range when i'm doing it. There's no focus all the way in then back track until the item is in focus. I get lost, and find it so bloody hard to focus, especially with the smaller / darker viewfinders of the later low-medium range dSLRs. I can turn the focus ring when the camera is off. I can change the direction of the focus ring in the camera's menu system. I don't get it. Is it all digital, and what's so wrong with the old manual focus rings where you had set measurements and an absolute minimum focus andan absolute maximum focus. Am I crazy? Am I just anal retentive. Is this on all lenses, and why do new lenses have these digital focus rings?
