Ok..... Here are some star tests with the 58mm. No Milky Way this time of year (only the less bright outer bands of the galaxy) so I only had stars and constellations to shoot. I wanted to test this lens wide open on the night sky to see how well it preformed compared to my other lenses I have & used to have. This lens has some coma at the very edges but its not bad wide open compared to the 50mm f/1.4G or D. This is why this lens will be great for astrophotography at f/2.8! Below are some examples. I tested several at F/1.4 and went as high as f/2.8. At f/2.8, nearly all of the coma goes away, however some is still there (minor) as seen on a FF 36.3mp resolution. There is some light pollution in the sky & that is why some images are not evenly exposed. Some are brighter on the left of the image due to the light pollution. Anyway, this should give some of you an idea of how well the lens performs when imaging stars. High ISO images will be nice too, but to get the best quality, use a tracking mount. I use the AstroTrac.

There was some CA on the brighter stars, I removed that with NX2 CA removal. There is also vignetting at f/1.4 (brighter in the center) but the vignette removal tool in Capture NX2 will take it all away. So.... astro images can be taken at f/1.4 if needed with the addition of CA & vignette removal. Well, enjoy shooting the sky with your 58mm!

This fist image is of the constellation sculptor, it was shot wide open at f/1.4 @ ISO 200 for 3 minutes on my astrotrac. I even caught a meteor passing through and burning up... Also NGC 253 (Silver dollar galaxy) & NGC 288 (globular cluster) can be seen to the lower right....NGC 247 is just above those.

This image is a f/1.4 100% crop of the top extreme right corner (horizontal)....

Here is a full shot of Orion. Its not processed the best, but I'll try again later.
ISO 400 @ f/2.8 for 5 minutes.

Here is Jupiter in Gemini:
Gemini is horizontal and of course Jupiter is the brightest object at lower center of the constellation. Taken at f/2.8 for 5 minutes

Orion is stunning. So much wonder in life.
