Canon 24-105 STM

Has anyone here tried any Night Sky shots with this lens on a full frame 6D Camera?  Will F3.5 allow enough light at 24mm?

Re: Canon 24-105 STM

I've taken night shots with the 24-105/4.0 (on a 5D) so the STM lens will do on a 6D, no doubt about that. Question is what you want to photograph. Night shots are mostly longer exposures with the camera on a tripod so there is not always the need to shoot at full opening but YMMV.

Re: Canon 24-105 STM

Thanks for the reply.  I see what you mean about not needing to be wide open on a tripod.  I want to occasionally photograph things like the Big Dipper etc.  May i ask, generally speaking, what shutter speed do you usually use when photographing stars, i know it will vary depending on how clear the sky is.

Re: Canon 24-105 STM

star trails, combination of approximately 14 pictures stacked together

The only night photography I have done is street or landscape views and star trails. Shutter times up to 30 seconds. the above one are 14 or so pictures with a shutter time of 4 minutes each, stacked together with LR/Enfuse. No static stars but if you google "star photography" you will soon find settings that will you get started. Keep in mind that stars are a source of light, their intensity will not change much so once set you can forget metering their light.

(edit: shutter speed as seen by dpreview is a bit off I'm afraid)

Re: Canon 24-105 STM

O.K., i think i may have made a choice on my wide angle lens, i sorta like the Tokina 16-28.  I haven't seen a lot of night sky shots, a few but not a lot.  Does anyone have any experience with this lens?  Like most other lenses, it gets some good and bad reviews, one being that stars were sharp on the left side and like a 'blob' on the other.  I'm hoping it was user error.

The go-to lens for good value, high quality astrophotography is the Samyang/Rokinon 14/2.8. it is quite sharp (nothing close for less than $1000) and has none of the pronounced lens aberrations that matter most for star fields (almost no coma or astigmatism). The base version is all manual and about $300 while the more convenient version has auto exposure and is $400 - $500.

They also make a 24/1.4 with similar characteristics but narrower field of view.

Manual focus but you have to manually focus in the dark anyway.

Sounds like decentering rather than user error.

I know it's a bit more expensive but the Tamron 15-30/2.8 seems to get a lot more love. I have neither - just passing on what I've read. This backs it up:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=773&Camera=453&Sample=0&FLI=1&API=0&LensComp=986&CameraComp=453&SampleComp=0&FLIComp=3&APIComp=0

If you want this purely for astro work, a faster lens is an advantage, but for more general purpose ultrawide use the 16-35/4L IS beats both of the above, for just slightly more than the Tamron.

Re: Canon 24-105 STM

I think you're right since i have seen some shots with good definition of the stars.  he may have just gotten a bad copy
