RE: One photo every day: Full moon (249/365)
I've only used macro extenders in school. I've heard the range extenders negatively affect exposure so I've kept my hands off them. ;)
What shutter speed did you use? The moon moves relatively slow, but I'm a bit iffy about using slower than 1/100s, because even on the tripod it still has quite a lot vibrations when extended at 300mm. Especially if it's even the least bit windy.
But I'm actually going out right now to try again. Wish me luck.
If I've understood right, if you have a 2X range extender it also doubles the aperture, so with a 300mm f/4 you would basically have 600mm f/8.
I could try one if I could test it for free, but wouldn't invest a lot of money on a extender without testing.
On the most successful photo I had 1/15, ISO 100 and aperture at f/20. I was taking the photo on balcony so with glasses (and opened up one of the windows to get the photo) so I didn't think of the wind.. or even of the moons movement.
Good luck :)
Edit: Damn it was cloudy in here, couldn't get any good photos.
I wonder what it'd be like to shoot through a 600mm lens with a 2x extender...
f/20 could be a bit overkill. The sweet spot in terms of sharpness of almost any lens is usually at f/8 to f/11, and most lenses can focus the moon with those, so if the theory is right, you should be able to use much faster exposure times. I'm fairly certain that the moon does travel quite a long distance in 1/15s. However negligible it may be.
Right now I'm pre-processing my photos, so I'll be back when I've fully edited them.
Btw. It looked like the full moon was last night (maybe in the morning hours), because as I was shooting now, the right side of the moon had started to go into shadow.
