I do a fair amount of tricky flash--I light up trains at night. A flashmeter is essential for me. Remember, the trains aren't there yet when I'm setting up my camera. With a digital camera I generally don't use a meter in the daytime. With my vintage cameras I almost always do. It's quicker than fooling with getting an exposure from a DSLR, and I like the vintage work flow when using these cameras.
