Yeah, I might have to look into something like that.

I was out last night doing some test shots with a Nikkor 50mm f1.4 a Tamron 15-30 f2.8 lens, first to try to capture the horde of lightning bugs around here, and then to see how the star field would look using those lenses. Results were disappointing. First off it is extremely difficult getting the focus correct. Apparently "infinity" doesn't work as well as you would think it should. Especially with the depth of field being so narrow with those large apertures.

I played around with the ISO settings on the 15-30 and I could definitely see more stars showing up the higher the setting. All exposures were at 30 seconds, which is max in the camera. Maybe the 50mm f1.4 could benefit from higher ISO values, but I didn't try that yet.

Not sure I could ever get the lightning bug shots to work out. They seem bright to the naked eye, but apparently not so much to the camera sensor.
