With the lenses I typically use, I find focussing at full aperture to be much quicker and more accurate than at a working aperture of one or more stops smaller than maximum aperture. With the f/6.8 Telyts it's not a problem because I sendom wish to use them at any aperture smaller than f/8, but even at f/8 I find focussing them more difficult and slower on any camera other than the SL or SL2. With the 280mm f/4 APO I find focussing at f/4 to be quick and accurate at full aperture, less so at a working aperture f/5.6 or f/8. Anything that slows me down means I'm less productive: I'll miss fleeting expressions or postures more often. This is why I don't consider the lens adapters and Nikon/Canon bodies an adequate solution to the Digi-R problem. And after using the 280mm f/4 APO, the comparable focal length/aperture C and N lenses are a cruel joke.
