That would be front focusing, would it not?

Hi Tim. I used to shoot bike races when I was younger using a Pentax MX manual focus,

https://www.pentaxuser.com/photo/the-late-bob-smith--british-champion--17409/lar...

..... It's easier these days with the modern stuff. The best advice I can give is to pick a landmark where you intend to take the shot (track marker WHY), start panning the shot early and keep the swing smooth and steady, trip the shutter just before your subject reaches the chosen landmark.........this is the important bit........keep the camera moving (follow through) with the panning. Plenty of practice helps!

NB Depending on the camera, use AF-C constant AF and it may help to let the camera pick the focus point on auto.

Maybe so, The FA-43 Ltd. FA-31 Ltd and FA-35/2 on the K10D all outresolve the Planar on the Nikon D200, both 10MP cameras. I'm only saying the Planar is the benchmark they use. There are only a handful of lenses thet outresolve the Planar at f/4.

Just like those who need the best from APS-C are already using Voigtlander, Zeiss and FA Limiteds.
Apparently there's a lot of EOS 7D owners chasing FA Ltd's

how relevant is this for lenses designed specifically for APSC then.

Are you saying that if Pentax bring out a 20mp APSc down the line that none of the current lenses available would be able to take advantage of the extra resolution?
There are very few lenses that can outresolve the "benchmark lens" (Zeiss Planar T* 50mm f/1.4 ZF) the original release date for the Planar was 1896 so producing a better lens is very unlikely, although it has been done a handful of times, we've hit the physical limitation for lens resolution and therefore adding more resolution to the sensor is pointless, it will only reveal the limitations of the lens in use.
