New Canon 35mm F1.4L ii Any good for astrophotography?

[Turbo Hampster]

Hi Guys

Has anyone had the chance to try out the new 35mm F1.4??

Is it better for A/P than the previous one?

Thanks in advance

To all,

I just received mine today (9/24). It is awesome! I did a quick star test, and it is by far the best lens I've ever star tested. The stars are pinpoint across the field of view, even wide-open. However, there is very slight coma in the extreme upper right corner. This is probably due to either the sensor not being perfectly flat or a slightly de-centered lens. It is negligible if you ask me. I can actually use this lens wide-open. It is far superior to the Sigma 35mm Art lens I rented for the Perseids. Below, you will find three crops at full resolution. I'll be able to do a more thorough testing of the lens once the Moon disappears from the nighttime sky.

Thank you for doing these tests. I've really been wondering how the coma was. I notice however that there's some chromatic aberration in the last pic. How is the chromatic aberration on stars compared to sigma?

Hi Wade

Thank you so much for taking the time to post some pics! I really appreciate it

Here is the star testing result from the Sigma Art 35mm f/1.4 lens I rented. My version of the new Canon 35mm f/1.4L II lens is definitely better. I'm very pleased with the new Canon 35mm lens. It's the best lens I have ever used for astrophotography.

I assume you meant there was a little coma in the middle picture of the Canon 35mm f/1.4L II star tests? The last picture is near perfect.

I try to help my fellow astrophotographers as much as possible. I highly recommend the new Canon 35mm f/1.4L II lens. It is the best lens I have every used to astrophotography wide-open, especially given the fact it is nearly flawless wide-open at f/1.4. That's an amazing feat.

Seems like the lens is outstanding but what about vignetting? A full frame uncorrected example would be very welcome here.

If your camera support in camera vignette correction images with and without this feature would also be very welcome.

Here's an example of the vignetting at f/1.4 (i.e. wide-open). As is expected at this wide open aperture, there is quite a bit of vignetting. It's hard to tell, but probably at least 2 stops.

I always have my in camera vignette correction turned off.

Thank you very much - the vignetting is quite even and might be possible to correct with a flat frame without too much loss of contrast. The centre of the field seems to be splendid and very useful as is. Interesting ... food for contemplation...
