So here is another thought on the loss of the onboard flash:
If you want both GPS/Astrotracer and flash how do you do that?
- Flash on board and GPS external? Nope, won't work, the flash will not popup with the O-GPS unit on and no external flash can be attached.
- GPS on board and flash on board? Might be the best solution but maybe there is no room for both. And the popup flash does not play well with larger lenses.
- GPS on board and flash external? Yep, that works.
I can understand the lamenting from those that used the on board flash. No one wants to see something they used go away. For me, I've taken over 20,000 images in the last two years and have not used the popup flash once. However, I do geotag every shot that is taken outside of the studio. But if I wanted to geotag and use a flash I could not do that. Now you can.
If you look at it from the standpoint of engineers saying "how can we accomplish this" then the loss of the onboard flash is the only way to go. I know that does not help those that are upset by its loss but perhaps following the logic it at least makes sense.
The loss of the onboard flash for slave triggering is another matter. I don't use that as I use radio triggers but for those that do use that feature what do they do now? I'm very much hoping that radio control for flash is also built in. Seems unlikely since the specs are now published, mostly, but that would make a lot of sense if there is not going to be an onboard flash controller any more.
