Spring is still a ways off here in the Rockies, but I did take advantage of some recent nice weather to field test my new Nikon 500mm f/4 AFS G VR Nikkor telephoto lens. In case you missed it, I switched to this lens recently after selling my 600mm f/4 VR. You can check out my podcast to hear about my rationale for switching.
I hit up the local nature center, where numerous bird feeders are set up. We don’t get much in the way of colorful birds here at this time of year, but the small ones are out in force, including chickadees, house finches, juncos, and the occasional woodpecker.
I put the D810 on the lens, rigged up the Wimberley gimbal head, and staked out the feeder. I shot everything either wide-open or at f/4.5 (1/3 stop down) to see how well this lens would do. In nature photography, it’s important to be able to shoot as close to wide-open as possible to get smooth backgrounds and maximize your shutter speed. Also, the better a lens performs wide-open, the better it will do when paired with a teleconverter. I haven’t yet gotten around to testing the 500VR with the new TC-14EIII, but that test is forthcoming. With the D810, I can use the in-camera crop modes instead of a TC, with the added benefit of being able to quickly switch crop modes on the fly. Of course, you can always choose to crop later, which can be a useful tool when shooting moving animals. Sometimes I want to compose loosely because the animal’s movement is unpredictable.
D810 Crop Modes
- FX (36×24): 7360 x 4910 (36.1MP); focal length multiplier 1.0
- 1.2x (30×20): 6144 x 4080 (25 MP); focal length multiplier 1.2
- DX (24×16): 4800 x 3200 (15.3 MP); focal length multiplier 1.5
As a quick aside, what you can see from the above chart is that with the Nikon D810 (or D800/e) my 500mm lens can be used as a 500 (FX), 600 (1.2x) or 750mm (DX) equivalent angle of view and still deliver images that match or exceed the resolution of my Nikon D4. The only drawback, of course, is that the D810 can’t shoot 10fps.
Sample Images and 100% crops
Here are a couple images I grabbed with the D810 and 500mm f/4 AFS G VR Nikkor. Click on an image to enlarge it. I was approximately 20-25 feet (6-7m) from these birds when I captured the images.
The Nikon 500mm f/4 AFS G VR is one sharp lens. My subjective opinion is that it’s slightly sharper than the Nikon 600mm f/4 AFS G VR. When paired with the 36MP Nikon D810 DSLR, you have a very versatile telephoto lens, even without a teleconverter. It delivers smooth out of focus backgrounds and offers stabilization for times when you need to use slower shutter speeds or a monopod. It’s light enough (8 lbs) to hand-hold for short intervals, or mount on a Wimberley Sidekick (although I still prefer the full Wimberley gimbal head). You also don’t need a massive tripod to support it (a 3-series Gitzo carbon fiber tripod is plenty). With the 600mm lens, you definitely want to use a more robust tripod (5-series Gitzo or similar) and a full gimbal head. You can also dismiss any idea of hand-holding it unless you routinely pump iron.
If you have unlimited resources, the hands-down sharpness winner (based on my reading the specs) is probably the 400mm f/2.8E FL ED VR Nikkor, but that’s a $12,000 piece of glass! Nevertheless, if you have that kind of cash lying around, pair it with a D810 and you can use crop modes to get 400/480/600mm equivalent angles of view without a TC.
