I would never use a pop up either. Not closed minded. Some of my bodies don't have one and I ain't retrofitting them. :mrgreen:
As for the one body with a pop up flash,
I find it a lot more closed minded or just plain lazy to not have basic gear with you when ever you are shooting. I always have 1 580 EX with me no matter what the situation.
Well, I'm sure if we all had free access to equipment, we'd all have bodies with no flashes, and numerous speedlights (among other things).
But it all costs, and some may not be able to make additional purchases.
Been there, Done that and I have the t-shirt. After 35 years, i have managed to put together some gear now so I can shoot in ways that I would like. I make no apologies for it. I know the sacrifices I have made to get some of the gear I wanted.
Far too many times however I hear photographers bemoaning the fact that they left a basic piece of equipment at home because they didn't want to carry it. I feel the same way and would agree when hiking up a mountain, but it amazes me the number of people that drive to the door, get out at some location and start shooting only to find that they don't have some simple piece of gear that they already own.
If you don't own the gear, then you do the best that you can and do your best to achieve the results you are tying to get. Been there and done that, for several years. As much as it might be a disappointment there are times when you might not be able to shoot at all. It happens. It's life.
This isn't brain surgery, and what we are doing isn't life and death.
