will the VK750 work as an optically fired high speed sync flash?

Can yo define high speed? you want to capture the bullet inside the balloon? that I wouldn't know. I can tell you I use this mounted on a tripod behind my object, my camera's flash triggers it (no need of extra wireless triggers) and it has worked fine. Any shooting speed my camera can handle with its integrated flash also works with this. I got a Nikon D3100.

No. It's response time is fast enough for action photos but not for high speed motion capture.

The question said SYNC, and NO, VK750 does NOT have a HSS option (to allow use with very fast shutter speeds). But of course, it is a speedlight, and low power levels do have an extremely short duration, which easily freezes motion (like any other speedlight).

Yes, I've used mine with SB 600, SB 800, and SB 910. I do not feel it syncs as well with any external flash as with other Nikon SLRs though.

If your flash has a hotshoe it will work. It won't send TTL information, but that doesn't bother me as I shoot so much in manual anyway and like to be in control of my exposure.

I purchased the flash for my Canon , I believe it can be used as a universal flash as long as it's a standard shoe mount.

I don't know but I'm in the process of purchasing one of those flash. I would suppose it would work

It should provided you buy the version of the receiver with the correct mount type for the flash unit. In most cases this is not going to be an issue unless you are trying to use either a receiver or a flash that has a Sony/Minolta flash mount, but just don't expect a flash synch above about 100/sec from these units. Other than that I'm quite happy with the 3 NPT-04's that I have.

I don't seem to have any problem with synch speed of flash to shutter speed. I have used the triggers for some time now and even purchased another set for more lights. All of them seem to work fine with whatever synch speed I need. I have used a range of shutter speeds from 1/60 to 1/200 depending on how much ambient light I want for the background. I have never tried to use them with high speed synch at this point. I have two types of speedlights that are all for Canon equipment. I have a Canon 430EXII and two Yongnuo YN560II. Hope that helps! P.S. what the other two folks said also.

There is no hot shoe for an external flash so im going to say probably not unless there is a way to do it via usb which I doubt because the usb seems to be data only. But the built-in flash is very good

Why wouldn't, if the flash syncs with your hot shoe of your Canon T3i ? Your only extending the technology that exists to any flash that possess TTL.

You can set the synch speed at 1/125 and you should be fine. Also check your curtain on the camera. Sometimes people have the curtain set to the beginning of the flash and some at the end. Experiment tithe that if the 1/125 is problematic. A fast shutter isn't really necessary.

It wont, you can use another flash with a universal hot show such as yognuo. Is also less expensive.

No. I use it quite often on both modes and it works very well. I assume you mean flash.

Yes, the flash will fire automatically when synced properly with your camera.

I don't have the answer to that but the flash failed the 2nd time I turned it on and I returned it. I do not recommend buying it.

I checked the Sigma website. It appears to work except for built in flash. http://www.sigma-photo.co.jp/english/flash_and_accessory/flash/flash_610dg_super_match.html

I tested it with http://www.amazon.com/gp/product/B006OY4I8G/ref=oh_details_o01_s00_i01?ie=UTF8&psc=1 Atech Flash Pro-37U USB 3.0 True SuperSpeed 3.5" Internal / External Flash Memory Card Reader w/ Front USB 3.0 Port. Works fine, but need hi-speed USD Flash or similar device.
