Yeah....this thread got a lot of traction I guess.
It was never said that ob flash was the best option, it is just a convenient option. If I am out and about....say...on the beach .....and just have my camera.......and there is a late afternoon shot I want to take on the beach.....and I want to take 1/4 power fill flash with the ob flash.....I take it. But now....I will need to always take a flash with it, or increase the shadows in LR since I am using Raw. It has never said that in certain situations, using an external flash is the best option....that is a no brainer. It is just in those instances where you just want fill, that was an option. Now, if they don't have an ob flash, that, of course, will not be an option. I don't think anyone is saying it is a deal breaker....it is just that it is so easy to use ob in certain situations where it works very well.
