High Speed Sync

Is there any draw-back to setting my Canon 7D up for high speed sync and leaving it that way>

I think that it is hard on your flash and batteries. Instead of one blast, its a rapid fire blast that eats batteries.

If you use an external battery pack, you'll get faster recycle times AND not exhaust the flash's internal batteries. I use a Bolt external battery to power my 600 EX RT when I shoot weddings and have yet to get to 50% power left.

Yes!, main disadvantage will be a significant loss of power due to how HSS actually works. This reduces the effective distance to around 5 feet. You can google "hi speed sync" and find many explanations, or get Bryan Peterson's UNDERSTANDING FLASH PHOTOGRAPHY.

I don't know the 7D since I shoot Nikon. I suspect they may be similar.
If so you can set it up that way but still dial it down in actual use.
HSS is great for darkening the background exposure.

No. HSS is only active when your shutter speed exceeds the sync speed. The rest of the time the flash acts normally.

CORRECT!

Aside from the battery comments above, using HHS will often mean you have to use a more powerful flash/strobe. (The very high dollar model)

Your flash unit is most effective at the Max. flash sync. I think Canon goes to 1/300 sec. That is your most effective setting for your flash. You really shorten your range and your flash works a lot harder in high speed sync. It is designed primarily for balancing daylight outside with a small F stop. It is good for that but I wouldn't leave it set their.

The reason to use high speed sync is to use larger apertures in direct sun light. Outdoor portraits with the sun behind the subject requires a fill flash. You can still get the bokeh you want with HSS.

Agreed. You lose much power when using HSS. I wouldn't leave your flash on HSS. Put it there if and when needed and get close to the subject or it's useless.

I really don't understand why you would want to do that, I can see leaving it set to second curtain, but high speed, why? You loose a good 21/2 to 3stops of light at that setting for once.

Only above the maximum normal sync setting.
Lower than that, it works in the standard way.
I leave mine on Auto FP ( Nikon-speak for HSS) all the time.
Do any of you who recommend not setting it to HSS ever use it?
You are guessing.

Of COURSE you should leave it in HSS. Those who tell you not to obviously do not know how it works. As long as you are below the sync speed, HSS is not active and there is ZERO impact. Once you go past it, then HSS comes into play, but it is seamless and your flash will continue to work. If you start getting up into the 1/1000 sec range and shorter it is true that the output begins to drop, but it will be obvious.
If HSS is not active and you attach a flash, the camera will automatically limit the shutter speed to the max sync. Why on earth would you intentionally cripple your camera??
This is the part of photography which require one to understand the equipment and think.
All my camera are set to HSS and have been since the feature was introduced.
