I suppose there might be something different when you move to 1/500th but I am not sure that what governs achievement of a 1/500th sec speed means that it creates problems for the cameras that has been suggested
I have an Agfa Isolette I which has 1/25th; 1/50th and 1/200th speeds and I cannot say that the highest speed affects the camera's handling. My 1/200th is as smooth as the 1/25th.
If there was a 1/500th would this create problems that is inherent in any 1/500th? I doubt it would.

Hi Pentaxuser,
The 1/500 speed requires a shutter spring with double the force. You can even feel this when engaging 1/500 and cocking the shutter.
Next time you see an Agfa Rekord III with the Synchro-Compur shutter, try it.
So what happens? The shutter shock makes the movable front element of the lens "twist" a little bit, blurring the image. Perhaps because the (new, replacement) grease in the helicoid of the lens should have been more viscous, so my fault perhaps.
Anyways, the film flatness of the 6x9 agfa folders wasn't so good as well. All in all what I got, and which has correspondence with some 36MP scans of agfa Record III negatives i saw on the 'net, is that the resolution of the camera is fantastic compared with 35mm and also compared with 6x4.5 negatives, but it is still not using to the max the potential resolution of the 6x9 format, particularly on the corners. And I blame on this, in #1, the film flatness, and in #2, the fact that the lens is a front-cell-focusing type, and thus it will suffer at some shooting distances.
