I am having a bit of a problem with the zoom function on my 600 ex rt in that it seems to be random as to which setting it chooses! Sometimes, I switch the flash on and it will not zoom beyond the 105 of the lens in use. Today, I have switched it on and it will happily zoom out to 200mm in manual zoom mode. I can't figure out why this is happening and it is a nuisance as there have been occasions where I wanted a smaller pool of light on the subject but the flash was in auto and I could not change it! Could anyone shed any light on this please?
Thanks
Thanks
