My sister has a meadow that has literally thousands of fireflies. In late June to early July they put on quite the light show. I've found them relatively difficult to photograph, their lights are both ephemeral and dim. Any lens f/2.0 and above gives you nothing but a black screen. These were taken with my trusty K 50mm f/1.2 wide open, focused at infinity. First shot is .6 sec the second is 1.6 sec.
Enjoy.

That must have been a site to see Salty - nicely done. It's been a while since I have seen any fireflies.

Thanks Dave. The photos simply didn't do the spectacle justice, there were literally thousands of fireflies, all blinking on and off mostly just above the meadow grasses but some well up into the trees.

The first shot has enough light sky it kinda washes them out, but #2 captures them very nicely! Fireflies are so much fun to watch... One of the few things I miss about living back east...

Now that's cool, old buddy. We occasionally get swarms of fireflies in the backyard, but I've never been able to generate the nerve to try to photograph them. Great job.

The 2nd shot does it for me... like their own little galaxy.

Thanks Jer, I had fun with them (well after I got over the dissappointment of about 20 blank screens taken with the DA 12-24 and the FA 35 f/2.0) The shots don't begin to do the spectacle justice, there were actually thousands of fireflies all blinking on and off, the meadow literally sparkled. And it was a big meadow, about 2 acres.
