Maybe some of you remember that I had promised to write a review on a lens my wife wanted to present me for having won the „NUTTER Awards 2018 / category: Best Obscure Mammal“. Here you go!

I don’t know if anybody has ever tested a lens for the mammal watching community. I give it a try.

At first let me explain why I believe mammal watchers have special needs concerning photo equipment / lenses and why they are different to those of wildlife photographers. The following table presents some of these differences – as I see them:

 photographing mammal watcherswildlife photographers
1often focus on finding as many species as possible in a given timeoften spend more time with a given species / individual
2often travel in groups and have to share space in a caroften travel individually
3cover more distance / have less time at one spot / want to be maneuverablespend more time with a given motif / spend more time in hides
4need photos to prove their sightings and for IDing their motivesaesthetical values are more important
5don’t mind to get a perfect shot, but are usually content when their target species is full framewaiting endlessly for THE special moment
6often use zoom lensesprefer fixed focal length lenses
7try to avoid tripodsrely on tripods
8because of 2, 3, 6, 7: like small, compact, lightweight lenses often need high light levels / heavy lenses
9prefer less expensive lenses / safe some money for a thermal imager, binoculars …pay enormous amounts for high end products

After nine (!) months of waiting I finally received my present. I had planned a trip to Spain in December. I took the lens with me – knowing that that time is not ideal for small mammals.

The last decades I have always worked with big lenses and so I am used to heavy weights. Now the lightness (less than 1,5 kg) and easy handling of the 500 pf really is something else. It is truly fantastic how you can move around, lay on the ground, raise it to photograph some overflying birds. And it’s small enough to rest it on your lap while you drive a car. For comparison: the Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR is about the same size, but 2,3 kg heavy.

Focussing / image quality

The lens you should directly compare with the 5.6/500 pf is the 4.0/500. I haven’t had the opportunity to do that. Others did it and found no differences concerning sharpness under „normal“ conditions. Following I give you plain results – and you decide if the image quality is good enough for you: 

It was mating season for the Pyrenean Chamois and I got several times the opportunity to shoot dashing males. The D850 + 5.6 / 500 pf combination delivered a less than 70% hit-rate, where the images were in optimum focus. This doesn’t sound much, but a passing chamois in full speed is very challenging and I could produce around 20 images while the animal was near me in an optimal angle. That makes around 6 photos. Enough for me!

Pyrenean Chamois leaping. The animal is so sharp, it is almost hard to believe it was actually in motion.
Another male jumping over a creek. Even with the difficult light conditions camera and lens had no problem to capture this moment.
Pyrenean Chamois landing in a patch of snow. The image is perfectly sharp, despite the snowing and I was a bit far away and had to crop it strongly.

A passing Raven (ca. 30 m overhead) held something in its beak.

Click, click, click – in the viewer I could clearly see that the Raven held a piece of baguette.

Later at home I cropped the image to find out if there were some mammalian traces between the bread halves (like some goat cheese or salami slices).

The picture clearly shows: It’s just a piece of plain, uncut bread, and if there had been a sausage end I would have clearly detected it – in the beak of a fast flying bird under a grey sky … I am still impressed!

Third opportunity to test focus speed and -quality: A bustling Iberian Chiffchaff moving in the canopy of an oak tree at around minimum focus distance (which is at 3 m in the 500 pf). This motif was even more challenging and it took around ten attempts (hand-held). But the result is again stunning!

Iberian Chiffchaff


Of course an F4 is to be preferred to an F5.6. An extra stop of light can have advantages. But: When ever possible I try to close the aperture to around F8 for extra depth of field. Therefore in many situations I don’t care about a minimum numeric aperture value. In low light though or when subjects are moving quickly, I would rather choose a F4 at 3200 than the F5.6 at 6400 – if I don’t have to worry about the extra weight.

I photographed this Roe Deer, about 100 metres in front of me, in the last light from my car with ISO 1000, the lens placed in the open window. With the 4.0/500 I could have used ISO 500 and make a portrait afterwards.
Same spot, next day: the Red Fox replaces the Roe Deer. Same thing: The 4.0/500 would have been a little advantageous.

Vibration Reduction

Dashing Chamois, Bearded Vulture in flight, whirring Chiffchaff – I held camera and lens just in my hands and the VR worked excellent. On the other hand there are many occasions where I depend on a tripod (mainly avoiding high ISO in low light) – or some other kind of support. In the alpine zone of the Pyrenees and the Cantabrian Mountains I relied invariably on rocks as a tripod substitute and used a jacket to get the camera in the desired position. I found it much easier to align the small 500 pf compared to a bigger one. Rock instead of tripod: this might not sound professional, but consider the rough terrain I was in. I am sure I got more opportunities to shoot with the light 500 pf, because I was faster and more mobile and thus created more situations, where I could actually press the button.

I saw this Chamois moving towards the river. With a tripod attached to the camera I would not have made it in time through deep snow to catch this special moment.
This Bearded Vulture was not on my mind at all, instead I was busily taking pictures of Chamois. Then I saw it from the corner of my eye, raised my camera and used the one or two seconds during the bird flew a turn …
… same thing with this Common Griffon. The VR again did a great job.

Focal length

I personally believe that zoom lenses are overrated. Most of the time people use the greatest focal length available anyway. And when you are tired of having your chamois full frame, wait until it leaves or leave yourself and then take another shot from a greater distance.

Snot: In a habituated herd of Cantabrian Chamois near Fuente Dé it was no problem to get that close (Image is cropped).
This Chamois across the river was browsing on pine needles. In that moment I wished I would have had a stronger lens to document this special feeding behaviour more precisely.

500 mm: It doesn’t sound like an allrounder, but it really can be. At 3 m minimum focus distance it’s good enough to get a decent image of even the tiniest mouse. On the other hand 500 mm can be also good for landscape photography. 

The Pyrenees: Most people think of wide-angle lenses when it comes to picture landscapes, but a 500 mm lens can do a great job too.

Then, when it comes to really shy animals like Chamois that are exposed to hunting or a Snow Leopard high up on a ridge, 500 mm might not be enough. But you just have to make a decision: above 500 mm there is not much worth debating. The 4 / 600 mm and the 5.6 / 800 mm are both monsters and you then play in a different weight class.

I saw this beautiful male from below and wanted to have it in my collection. I knew that hunters had been in the area quite recently and that the Chamois were shy, so I had to ambush, but never got close enough. For my taste this image is too strongly cropped. Another moment I wished I could have used a lens with more focal length.


The Nikon 500mm F5.6E PF is a super sharp, lightweight, easy maneuverable, easy to use handheld, allrounder lens – that has the potential to upgrade a mammal watcher to a wildlife photographer. When it comes to taking pictures in a dark forest or over long distances, I personally prefer a lens with a smaller F stop value or a longer focal length respectively. If you say the greater weight and bulkiness of the bigger lenses is not worth it, than the 500 pf is your ultimate lens.
