Originally posted by mcgregni However, tonight , with the V6II and PEN.A.001 firmware, with the flash mode set to Manual, I was unable to gain any good control over the flash exposure. The RF60x display showed the changes to zoom and flash power I was making on the V6II, but the actual light output was not consistent.
Did you set the RF60X's group to "M" (manual) on the V6II?
Did you use shutter speeds that did not exceed the sync-speed?
If so, your results are not good at all. AFAIC, the V6II should not care about the lens, as long as the above two conditions are met.
Originally posted by mcgregni I also tried with an RF60x on the camera as 'Master', and RF60 as slave (both running one of the 'X-TTL' firmware's), and again there was no consistent Manual power control ....... hmmm, seems strange, but perhaps just a consequence of the way the firmware works.
That doesn't make sense to me at all, unless it happens with any lens for some reason.
The RF60X lacks any means of digital communication with the camera, so it doesn't know whether the attached lens has an "A" mode, is fully manual, or whatever. The RF60X should work independently of any P-TTL matters (like HSS or lens type).
This experience suggests to me that your conclusions about the V6II not working with a fully manual lens may not be correct, or that there are multiple bugs (in the V6II and RF60(X)) involved.
Originally posted by mcgregni Changing the lens back to the D FA28-105 solved all the problems and I regained perfect manual control again.
Did you try the RF60X on-camera again?
As I said, I believe it to be technically impossible for the type of lens to have any influence on the reliability of the communication between an on-camera RF60X and an off-camera R60.
Originally posted by mcgregni I have seen the posts on Cactus Community Forum where Antonio explains to ClassA that eventually there will be a merging of the firmwares, allowing mixing of the different types. It appears to be that for those of us wishing to use both autofocus lenses with TTL / HSS, and old manual aperture lenses with Manual flash, then this could not come soon enough!
I don't understand how you arrive at this conclusion.
Did you not just report an issue with the "A"-type firmware? If that is confirmed then the announced roll-out of the "A"-type approach to all firmware variants could mean that the latter get broken as well.
I hope your issues can be explained in a different way. Otherwise, I'd encourage you to report the problem to Cactus before it spreads to all other firmware variants.
