Here is a wild idea, put blue tooth in the flash and upgrade the ST-E2 to ST-E3 with blue tooth and add a-b-c grouping. Use off the shelf blue tooth chipset (lower cost), make an iphone/ipod touch app to set flash via blue tooth. No need for dip switches just pair the flash with you command device and don’t worry about other photogs triggering your flash. You could probably get 30 ft range easy which in most cases would be sufficient.

Surely you mean ‘alas’, not ‘alos’? Do they come with gyroscopes?

My journey with DSLRs began back in 2003 with the original Digital Rebel. DSLRs changed my photography for the better like nothing else. Five years and some 25,000 shots later, it’s still going strong. Along the way I upgraded to the Canon 30D, which is a fantastic camera as well. When the 40D was announced, I decided to wait until the 50D sometime in 2009, but wanted a newer backup/second body for my photography needs. So when the XSi/450D was announced, it sounded like a perfect fit for my needs.

When is the “winter” that you were referring to? sorry i’m living in a tropical country. No seasonal changes here…

Does this flash do the laundry too?

(spec list is a dreamer’s wishful thinking)

Would the Metz flashes built by Canon still work then or would they be messed with by Canon to be as consistent as their current flash line?

Be careful what you wish for…

Some of the new fractal based Antennas are very efficient and fairly wide band.

for example in cell phones

Radio Mics have the ability to change channels within a band, so that rented and owned equipment can co-exist on a particular show. They can’t (normally) leave a narrow band, because the antenna and electronics are performance-optimized for that band. Example: wireless lavalier mics use the cable from beltpack to mic as the antenna, and they work horribly if the cable is bunched up.

There’s no “direct” conversion between mWh and mAh – it’s mathematically dependent on the voltage. You’d need to be talking about 0.625V batteries for 2500mWh to be 4000mAh.

Maybe it will hold 5 batteries for better recycling time and longevity.

Hahah, fat chance… :)

I wish Canon would get in bed with Profoto, and Profoto would make a true pro flash for Canon. Something where the Profoto flash would talk to the 1ds4. Something much more powerful than the 500. There is a need.

Is that because you’ve done the math and know that you need a guide number of 70m?

Switching frequency bands won’t ever be as easy as a menu selection. Antenna design depends significantly on frequencies, and the more gain you want out of an antenna the tighter its band will be.
