Shooting polar bears with the $12,000 Nikon 180-400mm F4E TC1.4 FL ED VR

10 May

In many respects, the Nikon AF-S Nikkor 180-400mm F4E TC1.4 FL ED VR is a dream lens. Earlier this year, with the support of Nikon Europe, I tested it out in some of the harshest conditions on our planet—on a special Polar Bear production in Svalbard, near the north pole.

I took this lens on two different expeditions—first in early April with temperatures reaching well below -20°C with wonderful low-light, and the second expedition at the end of April with the midnight sun and higher contrast. As a professional wildlife photographer, I have to trust my gear to perform and deliver the sharpest images possible, and while this lens took a beating (sorry Nikon) it survived the freezing temperatures and functioned perfectly while providing razor sharp results.

Construction and Handling

This lens is part of the new generation of E lenses with reduced weight compared to older designs. That’s important, since it makes hand-held shooting a lot easier. The entire body of the lens feels firm and well-balanced, although it’s a bit front-heavy in my opinion.

Compared to the much-loved Nikon 200-400mm, the new lens weighs less, and is in fact even lighter than the Nikon 300mm F2.8. The wide zoom ring and focus ring, plus the TC lever, make it easy to manipulate even when wearing the thick gloves required at this latitude, in temperatures well below freezing.

During my shooting, this lens “ate” a lot of snow and wind, and survived being transported for hundreds of kilometers on my snowmobile with nary a complaint.

Zoom Range

Without the 1.4X teleconverter engaged, the 180-400mm has wonderful range and the advantage of a constant F4 aperture. Going from one zoom extreme to the other requires only a 1/4 turn of the zoom ring, which is much quicker than the Nikon 200-500mm.

However, while 180-400mm is a usable range for large mammals or medium-sized ones that allow the photographer to approach relatively closely, its not long enough for safety if you want to capture a tight portrait of a predator like a polar bear. For that extra reach, Nikon has integrated a 1.4X teleconverter, which turns the 180-400mm into a 250-550mm lens at the cost of one f-stop—making it an F5.6 constant aperture zoom.

Focus

As you might hope from a lens of this type (and price) autofocus is blazing fast. It feels faster than the old 200-400, and also faster than the Nikon 600mm F4. I didn’t notice any hesitation or ‘hunting’ during focusing.

Aperture, Vignetting and Sharpness

Image quality at F4 is really great—not only usable but actually really sharp throughout the zoom range. My Nikon D850 was pushed to its resolution limit even with the widest aperture selected. When engaging the TC, the lens does get a bit softer, and there is very noticeable vignetting wide-open; the converter is there if you need it, but I’d recommend engaging it only when absolutely necessary.

100% crop (click to view)

Overall, the images came out crisp, sharp and with excellent contrast—even when shooting backlit subjects. I saw no flare, no ghosting and no noticeable chromatic aberrations.

Vibration Reduction

This lens features Nikon’s new-generation VR system, which is good for around 4.5 stops of correction. During my shooting, VR was very useful for hand-held shots.

Price and Value

The sadistic part of my personality enjoys looking in people’s eyes when they get all excited about the lens and ask me how much it costs. When I say $ 12,000 USD, the bright light of childish enthusiasm is quickly extinguished.

It’s a lot of money, but as the expression goes: “you get what you pay for.”

This is a dream lens with so many advantages, both optically and in terms of handling, and that comes at a cost. The cheaper and more approachable option would be the Nikon 200-500 F5.6, which costs a mere $ 1,500. As a friend of mine said, “I could buy eight of those for the price of one 180-400 F4.” I don’t know what he would do with eight lenses, but you get the point.

Final Thoughts

So the 180-400mm is a dream lens, but the dream doesn’t come cheap. For a safari in Africa, a project in Svalbard or any action-packed wildlife shooting it’s perfect. In sports or any activity where the subject is moving in your direction, this lens could be a great option. For capturing birds, small mammals or any subject where you know you’d end up cropping after the fact, I’d tend to go for a long telephoto prime instead.

So… is it worth it? That depends on your standards, requirements and the depth of your pockets. The 180-400 lets in an extra stop of light compared to the 200-500mm and offers much better sharpness, faster focus and better handling, not to mention the ability to reach 550mm with the flip of my thumb. I’d go for the 180-400mm without hesitating.

If your budget is tight and you can’t afford this lens, the Nikon 200-500mm F5.6 is a very attractive option, but it can’t match the 180-400mm for speed, critical sharpness or versatility.

Antarctopia: A Vision of Past & Future Polar Architecture

30 May

[ By Steph in Architecture & Public & Institutional. ]

Antarctopia 1

The most remote and climactically unforgiving place in the world, Antarctica has served as a setting for only the hardiest and most practical of architecture since its initial exploration in the 19th century. An exhibition at this year’s Venice Architecture Biennale examines how the man-made structures of the continent have evolved over the decades since, and how aesthetics could come into play in the future, adding some form to all that function.

Antarctopia 2

Antarctopia 3

‘Anarctopia’ is a pavilion featuring a model of the British Antarctic Survey’s Halley VI Research Station by Hugh Broughton Architects as well as work by 15 international architects and artists examining the provisional nature of architecture in Antarctica and new design proposals that go beyond the scientific, industrial and military missions that have directed the continent’s utilitarian architecture in the past.

Antarctopia 4

Antactopia 5

Directed by artist Alexander Ponomarev and architect Alexey Kozyr, the pavilion offers visions of snowflake-shaped structures covered in solar panels nestled into a snowy landscape dotted with wind turbines and penguins. The organizers hope that the project will have an impact on the design of real stations in the future. “Among enthusiasts and unbolt schemes dwells the promise of a new Antarctic man.”

Antarctopia 6

And while most of us will never get to explore the actual Halley VI Research Station in Antarctica, visitors to the Biennale can get up-close and personal views of models of the world’s fist mobile research center, which opened in 2013. The pods that make up the station are set on adjustable ski-like feet so they can be relocated inland to avoid being stranded on an iceberg, and raised above high snowfall accumulations.

Using Polar Coordinates In Photoshop

17 Jan

Make a square selection

1. Open an image in Photoshop (screenshots are from Photoshop CS2 on Mac). Higher resolution and size will give better results. I used a picture I found online on Freedom Wallpaper.

2. You need to make a selection that is squared. Use the selection tool, and set the aspect ratio to fixed:

fixed-ratio

3. Enter the same number in both fields. 1 and 1 works.
1-by-1

4. Make a selection.
make-a-selection

Apply The Filter

5. Apply the filter Polar Coordinates:
apply-filter

6. In this step, use the bottom radio button, marked “Polar to Rectangular”:
rectangle

7. Now your image will turn into something that may look interesting at best, but we’re not yet there:
after

Rotate And Apply Filter Again

8. Rotate the selection 180 degrees. There are a few different ways to do this. One of them is to use the Edit menu, then Transform and Rotate 180 degrees.
rotate

9. Now apply the same filter we did in point 5. But do NOT just choose it from the top of the Filter menu. We are going to change one of the parameters so you have to choose it from Filters > Distort > Polar Coordinates… again.

This time, choose the upper radio button, labeled “Rectangular to Polar”:
switch

Crop And Save

10. Crop your picture to get rid of the stuff surrounding your new circle:
final

Any suggestions, ideas? Feel free to comment on this article!

Tom Mangelsen – Polar Play

29 Oct

In March of 2010, nature photographer Thomas D. Mangelsen traveled to Hudson Bay in northern Manitoba to photograph polar bears and their young emerging from their winter dens. Watch as these tiny, months-old cubs play and wrestle while their mother keeps a close eye on them from the den. © Thomas D. Mangelsen 2011 www.mangelsen.com http
