The 50mm f/2.8 macro lens will be released soon, so I thought it would be interesting to see what everybody thinks is the best way to light macro photos on-the-go. I'm by far not an expert in macro photography, so please help me out on what to spend my money. On the one hand, there are 'ring lights' and 'ring flashes'. I did a quick calculation and it seems the Sony HVL-RL1 ring light with a light output of about 700 lux equals a flashgun with guide number 24 from a 1.1 meter distance. This means it should be bright enough for most macro shots. However, experience tells most photographers that flashes are always the way to go - but is this still true for macro shots? Then there are 'twin flashes' like the Sony HVL-MT24AM, which has two almost free positionable flash heads, both with a guide number of 24. With these, you should be able to control the direction of your light better. But not only are they extremely expensive, they need more time to set up and are bigger to transport than a simple ring light. Oh, and these have the 'old' Minolta hotshoe, while the RL1 already uses the standard hotshoe. Then there are of course cheaper versions from various brands of these things. However, in most cases I was not able to find the light output of ring lights (after all, the predecessor of the RL1, the RLAM only produced about 250 lux of light), and I don't know how well the metering works with non-Sony flashes on Sony cameras. What are your tips? Which setup do you use to light macro scenes outdoors?
