Thanks for all your responses!
Having both is certainly ideal, but I find myself forcing to choose one or the other. Shooting on a 7D, when using a long lens for shallow DOF, I need to stand further away from the subject and the lightstand. In windy conditions, the lightstand gets blown over all the time Sure I could use a sandbag, but it's a lot of extra weight to carry. My wife already dislikes the idea of me carrying lots of gear when we go out.
So I like to put my foot on the lightstand, which needs to be relatively close to the subject. In that case, I'll need to use a wider angle lens -> reducing blur.
I guess the ultimate solution is to go full frame!
if you need to stand further away, just PP your stand out if it's in your shot. I do that all the time when I need an environmental portrait with a wide angle but want to light my subjects with strobes.
In regards to sandbags, I generally leave those at home unless I know I'll be "shooting from the car". My gear bags are heavy enough to play dual roles and generally keep stands in place when needed.
And I disagree about FF being the ultimate solution (for lighting). I actually prefer using my crop sensor M when I'm using speedlites in broad daylight since I don't need to stop down as far for DOF, giving me faster recycles and more headroom in regards to flash power.
Your photos are superbalicious, btw. LOVE that DOF, and the lighting is excellent!Thank you kindly!
