Sigma 50-500mm Versus Five Star 500mm

Last night's task was once again chasing the moon on a cold winter's night. Using a Sigma 50-500mm APO DG lens, a late 80's Five Star lens and a Focal 2x teleconverter I wanted to satisfy some curiousities.
Both images were shot in RAW and not processed at all with the exception of saving the files to jpeg and resizing.





One was shot on very rigid, all metal tripod while the other was shot handheld.

Take what you will from this example. I am very surprised.
The Focal 2x teleconverter was attached to both lenses and both were shot at 500mm. However I think I can add that the Sigma image was shot at f16, iso 400 and 1/60th. The Five Star image was shot at f8, iso 400 and 1/180th.
And I will also add that the Five Star is considerably less impressive (than the Sigma) with most daylight situation and when panning.

I have the Phoenix version of your Five Star lens, and I didn't find the night time results too bad. However, like you hinted they're daytime performance is less than stellar

Both of these were cropped from RAW files and a one pass sharpen. Nothing more. Uploaded to flickr and posted here.
Again the Sigma image was tripod mounted while the Five Star image was handheld.

Here is the Five Star tripod mounted, f16 iso 200 1/15th unedited, simply saved to jpeg from RAW.

The 5 star lens is very good in day time also, I took some good shots at the boat races with one. The colers are bad with the lens is all I noticed.
as you can see in the 2 photo's. The second was taken with the 55-300.

Decent results with both lenses. Btw, is that a old Velbon tripod I see under the BIGMA?

And I would be proud of a shot like that of the lime green boat, Gulfer.
