AF-100 Problem with Lens and Adapter!
on Aug 9, 2012 at 7:18:50 pm

A production I am working on recently purchased the AF-100 with Tokina 11-16mm and Olympus 14-25mm.

The Tokina would look amazing however the Novoflex adapter we purchased allows the lens to wiggle ever so slightly when you touch the lens. This causes an unacceptable shift in exposure as well as the actual image. (I've tried replacing the Novoflex and problem persisted)

To add insult to injury, the Olympus 14-35 also has a quick little exposure shift around the wide end of the lens (say 14.5mm). For controlled static shots this wouldn't be a problem, but if I want to do a soft push on the zoom that exposure shift is totally distracting.

I've spoken to guys at B&H and a few others who have experienced a similar problem but have no solution! What can I do??? Is this just an attribute of the Novoflex adaptor and the Olympus lens on the AF-100 that nobody is talking about?? Are there any Lens/Adapter combos for the AF-100 that don't have this problem? One guy at B&H said he just resorts to using his one pancake lens because of the problem.

Lastly, is there a good cinema lens option like the Tokina 11-16 and Olympus 14-35 that doesn't have this problem and also has cine-direction rings so I'm not working with opposing directions when I pop on the Tokina 11-16?

I use a Lumix adapter purchased from Abel Cine, no wiggle with the Olympus 14-35 on the AF-100.

As for the other issues, welcome to the world of SLR lenses. The "features" you mentioned, like the iris bump, are part of the economical price point.
