One thing that keeps me from wanting to buy now it is that there is no way to mount it to your camera while shooting. They are in development on the Orbis Arm, that will allow you to fix the ring flash to yoru camera… but, that means there will be more cost.

There is another ring flash adapter out there, the Ray Flash, which sells for $300 (US). This attaches to your flash while the flash is on the shoe mount. Makes me wonder how much cheaper the Orbis will be once the “Arm” is figured into the price… maybe $250, or more even? The Orbis looks more promising as it has a larger surface for the light to dispurse. This would mean that the light would be softer than the Ray Flash.

Well, maybe if I feel ambitious enough, and can find the time (shyeah, right)… I can make a DIY ring flash that I’ve been eye-balling for a while now. It looks fairly simple to do, the final outcome is clean looking, and it has a bracket that mounts to the bottom of the camera body.

Along with a bevy of other fixes/improvements, the ones that caught my eye included:

• Focus acquisition performance in dynamic-area AF mode has been improved.
• Focus acquisition performance with contrast-detect AF has been improved.
• Auto white balance performance has been improved.
