Canon P900



The push to add more megapixels has slowed among point-and-shoots in recent years, but that hasn't stopped companies from expanding optical zoom to new heights. While it seems like only yesterday that 10x and 20x zooms where technological feats that we could hardly fathom, now we see 50x zooms on a daily basis and hardly give it a second thought.
Even so, Nikon decided that 50x just wasn't enough and pushed its new Coolpix P900 (MSRP $599.95) to a jaw-dropping 83x zoom (24-2000mm equivalent)–easily blowing away Canon SX60's longest ever 65x zoom. With a range like that, there isn't a shot that the P900 can't cover.
That kind of zoom can do wonders for people shooting anything from wildlife to the moon, but it does come with drawbacks. Steadying shots at 2000mm can be nearly impossible, even with Nikon's built-in image stabilization, and image quality suffers badly at full zoom. However, if you're looking for a camera that can reach out and snag a shot of just about any subject that you can lay your eyes on, the P900 has you covered.
Design & Handling
Like many superzoom cameras, the P900 is designed with a classic DSLR-style grip, but with a massive fixed lens on the front. Due to the P900's extreme lens, it's slightly larger than other bridge cameras–even the Panasonic FZ1000, which features a 1-inch sensor. Even the flash has to be built a bit differently; because the lens barrel is so long, Nikon has made an enormous flash that towers over the camera so the lens doesn't block the light.



 Even with its increased size, the P900 feels well built and not too front-heavy. This is mostly due to the deep grip and tactile leather-like material that covers it. However, when you're zoomed to 2000mm, two hands are absolutely required if you want any hope of getting a steady shot. Still, it's light enough the you can hold it in one hand–something you couldn't do if it were a DSLR.
The button layout is fairly standard for a Nikon point-and-shoot. The top controls include a zoom lever around the shutter release, power switch, function button, as well as both a command and mode dial. The rear controls are in a basic array and include dedicated buttons for WiFi and recording video. The side of the lens has an additional zoom lever and a snap-back zoom button.



The rear LCD does flip out and swivel, which is very useful when shooting overhead or at other tough angles. That said, it's not the best LCD. It's also not a touchscreen, but at this price point, with an 83x zoom, you can't expect everything
Performance
Designing a camera with a 24-2000mm equivalent zoom is an exercise in compromise. The P900 takes quite a few hits to its performance for the ability to reach out and touch the stars. That's not to say that it won't provide quality that's acceptable for people that want the absolute longest zoom on the market. But if you're looking for something to give professional quality images at 2000mm, the P900 is going to be a letdown.

Let's start with explaining how the sensor relates to the lens and its zooming ability. The 1/2.3-inch sensor gives the P900 a 5.6x crop factor and allows it to reach the 2000mm mark. If Nikon wanted to get better quality, it would have to use a larger sensor, which would mean dealing with an even larger lens. Obviously you can't make the lens much larger, so Nikon is stuck with this small sensor that you'd find in any other point-and-shoot.

 This small sensor limits both resolution and low-light performance. The P900 is capable of taking shots at an amazing range of focal lengths, but the further out you go, the worse the quality becomes. The wide angle shots aren't too bad, but once you get out toward the telephoto end of the focal range, the images are pretty much only good for social media posts due to grain and overall softness.
Another issue that stems from the small sensor is high-ISO performance. This comes in play in two different ways. The most obvious was is in low-light, when you need to bump up the ISO to properly expose the scene. These shots will look grainy, though you should be able to use most of the ISO range thanks to noise reduction. The other issue comes from shooting handheld shots at long focal lengths. When you're shooting at 1000mm plus, you're going to need a very fast shutter. That might mean bumping up your ISO even when it's light out, which results in a loss of even more detail. I wouldn't recommend venturing far above ISO 800.






 Video quality is also a victim of the small sensor. Frankly, the video captured on the P900 is underwhelming even under perfect lab conditions. I suppose if you absolutely need the zoom, it's a good reason to pick it up. However, if you absolutely need to zoom in 2000mm for video, I have to question what you're filming. Otherwise, you can pick up dozens of cameras or camcorders in this price range that will produce superior footage and give you decent zooming capabilities.
Shooting Experience
Shooting with the P900 was surprisingly pleasant. I'm not usually a fan of shooting with bridge cameras–especially one that I knew was going to lack the sharpness and performance I would be happy with–but the P900 wasn't terrible. This isn't to say that it performed up to my liking when I got the images to my computer, but the process of capturing the images was, dare I say, enjoyable.
The controls are very straight forward and have almost no learning curve for anyone that's used either a DSLR or compact point-and-shoot. I do wish the buttons had a little more feedback to them, though. A few times I wasn't sure if I pressed anything, especially the record button, due to the combination of slow response time and lack of tactile feedback. The top and rear command dials are also a bit on the loose side and rotate a bit too easily for my liking.
The EVF isn't amazing, but it isn't the worst thing I've looked through either. I did find myself using the LCD more than I usually do when shooting wide shots–only switching to the EVF for longer focal lengths. For the price you're paying for the P900, the EVF and LCD are no slouches.
On the subject of longer focal lengths, the camera zooms very slowly. Granted it has a lot of zoom to cover, but if you're hoping to snap to 2000mm quickly, you'll be disappointed. On average it took 6.3 seconds to go from 18mm to 2000mm, which is plenty of time to lose that perfect moment. One useful feature is the "snap-zoom" feature. It works when you're zoomed in on a subject, automatically zooming out momentarily, allowing you to find your subject. It then snaps back so you're ready to fire away.
