16-35 canon lens
Hi Tony
Quick question. I’ve noticed in a couple of your wide angle night shots the stars distort on the outer edges. I have the same problem with my Canon 16-35L and have wondered if getting the 16-35L II would fix the problem. Have you used both lenses and if so did the newer lens fix the problem.

I ask because we both are long time Canon shooters and you may have made this upgrade ahead of me. I too am fascinated with night photography and have been for years but the 5D MK II has really made it possible to finally get night skies with out star trails.

TONY:
Hi Chip
thanks for writing via tonyprower.com

I believe that the distortion of stars on the outer regions of the image is a combination of Chromatic Aberration and lens quality. I have not use the 16-35 mark 1 or 2 so I cannot answer your question. I use a 24mm f/1.4 mark 1 and I want to upgrade to a mark 2 because they have fixed a lot of the Chromatic Aberration issues. If the mark2 16-35 has addressed this issue also, then it would clearly be worth upgrading.

CHIP:
How great to hear back from you from the other side of this beautiful spinning globe. What an amazing world we live in where this is possible.

Funny I didn’t even think about prime lenses. As a landscapist in a rugged mountainous country I only pack zooms trying to keep my kit down to two lenses whenever possible. The 5D Mark II has really upped my percentage of good shots this year but it has also shown me that not all of my lenses are as good as I thought they were. I may have to re-evaluate and take another look at primes.

Iceland’s department of tourism owes you big time. I think your pictures probably put Iceland on lots of peoples radar. I’d come but every time vacation rolls around it’s the sunshine and warm weather I head for. :^)

Moments before a total lunar eclipse. 16mm @ f/2.8 @ 3200 ISO and no noise reduction. It’s a learning process for sure.

CHIP:
I’m really researching this lens after your email. I didn’t realize the advantage was 4 stops, that’s huge. What I did learn about was “coma” which is the problem I’m having with my 16-35 L series I (although the only time I see it is with stars never in daylight). I think the 24L II would be a great addition to my kit but then I read this review which I’m sure you’ve already read but it took the third read before I caught the part about coma. I still think it’s a great lens but I have to assume nearly all wide-angle lens have coma I only wish more reviews talked about it.

Thought it might interest you.

Canon 24mm f/1.4 Review

Coma
A lens defect which results in points of light appearing in the image not as points but as discs with comet-like tails.

Those shooting the night sky – especially the Northern Lights, appreciate fast, sharp, wide angle lenses. With its f/1.4 aperture, any wider lens will need exposures that are four times as long (creating star trails) or ISO settings that are four times as high (increasing long exposure noise). Expect some coma in the far corners and some purple fringing around super-bright (blown highlights) stars when shooting the night sky.

My conclusion was the first line in this review. The Canon EF 24mm f/1.4 L II USM Lens is, without question, Canon’s best-performing (optically and physically) and best-built autofocus 24mm lens. If you want the best Canon 24mm AF lens, look no longer. This is it.

TONY:
Hey thanks Chip
I never knew about ‘coma’ either but I guess that is the label for our problem. I think that stars are the ultimate test for a lens.

I will definitely upgrade to the mark II because it is the only lens which satisfies my needs. Many people opt for the Zeiss 21mm distagon, which is a bloody good lens, but for me it is a little too wide and the filter thread is 82mm which becomes expensive.

All things being equal, they match each other for quality, but that f/1.4 is a distinct advantage for the canon (which is also slightly better at landscape apertures.

Ahhh! to be able to afford them both -and the filters!!

CHIP:
I was corresponding with Wally Pacholka the other day (if you aren’t familiar with Wally, Google him up you’ll love his work) and he amazed me by telling me he uses a Nikon 14-24 on his Canon bodies and that it’s a killer combination so I started looking at the prospects of using Nikons incredible 24mm 1.4 lens and thought you might be interested in my findings. I’m going to do more research but these links are certainly eye openers. Less coma, sharper wide open etc.

It’s crazy expensive but we only want to buy one more of these lenses right? Don’t want to have to buy Canon’s 24L lll if it ever comes out.

Anyway enjoy.

P.S. Just bought a 8 stop ND and can’t wait to try it out.

TONY:
yep, I have been aware of the Nikon 14-24 for a few years and without doubt it is probably the best wide angle lens in the world… but the element is so large and bulbous that is is problematic to put filters on it. My day-time photography requires the use of dark filters, so I wouldn’t be able to use this lens during the day. It would have to be solely for night time use, and I am afraid I cannot justify the cost.

Anyway, thanks for the link to Wally!

Update:

Chip went ahead and bought the Canon EF 24mm F/1.4 mark II and was impressed so much with the sharpness. So I decided to take the plunge and upgrade. Here is a comparison of the old and new.

This is my first Attempt at Milkyway with the new lens…

…and later with the Canon 5D mark III
Hali Milkyway2

The nice thing about this shot was that I was actually able to see the stars in the live view for fine focus. The exposure simulation is a power horse behind Canon’s live view and a fairly indispensible tool (if it can do that!!). As for the lens, all stars suffer slightly with Coma and CA. Small finer stars are pleasingly sharp, but larger stars towards the corners of the frame are odd and need correction.

The weather was cloudy but as we turned the corner, a gap in the clouds allowed some beautiful, Winter light onto the scene.

The dawn is not a quick affair in Iceland. The colours can be good for many hours especially on a mid-Summer night.

    You have indeed a problem with the 14-24 to use filters. The lens has no filter thread (this would cause heavy vignetting). Lee has build a quite complicated solution to use filters on that lens. You fix a holder to the lens barrel, how this works can be seen in this video: http://www.youtube.com/watch?v=fMX5p9Iwx3Y
    Its not cheap either.

    Hi Chris, thank for the youtube link!! It looks great, but imagine sticking that in your camera bag. It makes the lens twice as cumbersome and I would only use it for NDs anyway. Wonder if there is a possibility of using Gel filters at the rear of the lens?

    It is unhandy, I agree, but at least, there is some possibility. The filter size is also a problem, as far as I remember its 150x180mm, so if there is a litte wind, this might cause additional problems. The lens has no option to use gel filters, as far as I know. But I don’t have it, its actually just on my wish list.

    Just stumbled across your site and I am going to have fun reading all of your posts. I will be coming to Iceland in October and cannot wait to take plenty of photos. I will be using a Canon 7D, what lens do you recommend for this as I am looking to get a new wide angle lens.

      Hi Stu, the 17-40 f/4 works well, but if you can afford it… the 16-35 f/2.8 markII is much better.
      Just had a look at your site… love your timelapse, you will have a fantastic time in Iceland. I am thinking of doing some Aurora Time-lapse on my Winter workshops…

    Hey There Icelandaurora,
    Thanks for that Before you begin buying Canon lenses you ought to be knowledgeable about lens terminology. Canon has a number of terms which are specific to itself.. Different camera manufacturers have their own as well. Canon and Nikon are the more popular camera makes. There are two main kinds of lenses.. Prime lenses make use of a fixed focal length. Zoom lenses make use of a variable focal length. Your budget plus the quality of photos you would like determines the lenses that you will buy.
    Keep up the good work

    Hey Tony & Chip,

    I have been digging really hard for an answer as to wich lens would be the best for nightscape/star/milkyway photography. There is no deffinite answer, but being a Canon shooter myself, I’ve looked in to every single option Canon made, regarding all perspectives of photographing the above mentioned. The only lens I haven’t been able to research fully is the new Canon 24-70 II, since there isn’t enough material on it yet.

    I have found none of the Canon lenses “perfect” for this specific purpose, and after looking at everything else, I can recommend the Samyang (also branded as Rokinon/Bowen etc.) 14mm 2.8 wich image-wise offers the whole package, for an amazing price. Yes the new sigma 15mm and the Nikon 14-24mm are better, but for the price it is amazing – and better than Canon 24mm 1.4 II.

    I know this blogpost is old, but i just spend the past few weeks looking into this, since i’ll be giving this genre a try, so I thought I’d share my findings for anyone stopping by this wonderfull blog, alast I myself ended up here in my own search 😉

    Big shoutout from Denmark to Iceland, really hope to visit your wonderfull Island soon, it should be on any photographers bucketlist!

    Hey Brian,
    I really am a fan of primes.
    What drew my attention to the Canon EF 24mm f/1.4 was a blog post years ago where they compared it to an old multi-coated Zuiko 24mm f/2.8 The old lens fared pretty well and is not a bad suggestion for a budget alternative. With an adapter it sits on a Canon DSLR and has completely manual focus and aperture.

    So I went and bought the Zuiko because I have an old Olympus OM1 and I figured I could use it on that. It looks weird on my 5DmkIII

    The blog post raved about the Nikon 14-24mm a few weeks later saying that it knocks spots off both lenses.

    Maybe I should try the Zuiko for some night shots.

    Hi Tony,
    I can tell it is my turn to reply, since another 18 months has now (almost) passed. I have ventured deeper into shooting night shots AND I have been to Iceland (already feel my life is near-perfect now). I switched to Sony this summer, and got myself the mighty Sony A7RII. Along with it I decided for another samyang 14 mm f/2.8 – this IS the best bang-for-the-bug wide angle astro lens without comparison. I just ordered the “Sky-Tracker Star Adventurerer” mount, so I will be able to do tracked shots in the future, I’m awaiting the arrival shortly, and I’m very much looking forward to give it a go – already looking into 200mm+ lenses for deep sky astro.

    For Canonshooters, the next 6D (mark II) should be arriving this year (or early 2017), and this may be a gamechanger, alas Sony has a pretty huge leap in tech with their A7S and now A7SII, for astro. I’m hoping to win the lottery some day, so I might be able to get me an A7SII for astro.

    Catch me on facebook if you wanna follow my adventure with Sony and the new skytracker 🙂

    Untill summer 2017, take care!

    /Brian
