Long Glass

[groveChuck]

Very nice thread to bring up with tonight's coming SUPER-MOOOOOOON!!!!!!!!

I'll be sitting with my GH2 and Sigma 50-500 praying for a break in the clouds

Super Moon:
AF100 with Canon 70-200 2.8L + 2x extender.

With the lens locked open at 2.8 (I guess technically f/4 with the extender) I still had to use ND2 on the moon.
ISO 2000 on the waves.

Per, did you get video of the moon on the GH2?

@gh2chuck Yes, footage shot both with the Canis Majoris Night and Sanity V5 settings (though the latter was after it was no longer colorful).

Technically, a 2x extender results in 2 stops of light reduction, so if you were shooting at the far end, you were getting 400mm f/5.6 (which is what I was shooting with natively on the 100-400mm as well). The size difference is from the use of EX24H.

Nice touch shooting by the waves.

Here is one of my perigee moon shots as seen from Athens, Greece.

What did you use to shoot with? I had some difficulty piecing it together from the tags.

Oops- 2 stops, of course. I knew that, wrote it wrong...

For reference, here are some moon shots I took from the same geographic location at different points over the last 6 months.

This includes the Canon 10-22mm, 100-400mm and the 600mm paired with a 2X extender.

Per- that 600 f/4 (with 2x) is incredible- great shots!
I have a 300 f/2.8, but can't use it on the AF because it's focus by wire

Thanks!

That sounds pretty frustrating about the 300mm. What model is the lens?

EDIT: Though it would be cumbersome, if you were using it for long-distance shots (like the moon) there's a chance you could pre-focus the lens using a compatible lens. I am not sure whether it would work or not, but it might be worth looking into. I set the aperture for the Canon lenses on the 50D before attaching them to the GH2, but I am not sure if the same approach would work for focus.

No model #, it just says EF 300mm 1: 2.8L ULTRASONIC.
It's probably 15 years old.

When I got the AF100, I wanted to use the 300 to shoot a Space Shuttle launch, but in testing it, found out it wouldn't work.
I use Canon bodies to set aperture also, but unfortunately, it doesn't work on focus... but thanks for the suggestion.


I just found this- you can't talk "long glass" without mention of the Canon 5200mm mirror... :shocked:

The camera body is at the far right and the sight on top!
