I haven't posted in a while, things have been petty busy at my end, but it's great to be back
About a month back I purchased myself an SB-700 flash, which so far has worked pretty well. One thing that I'm curious about is how the bright light built into the camera to assist the AF compared to the IR beam coming from the flash. The one built into the camera is definitely more noticeable to the naked eye, but can the camera see the one from the flash easier? Is the flash's more powerful? I've been using the flash's for a while now and it doesn't seem to have made too big of a difference, even in extremely low light. The only advantages that I could see is that it's less noticeable in the dark, and part of it doesn't get blocked by the camera's lens.
Which one works better for you? I'm curious in knowing whether the camera's or the flash's helps the AF more.
