I am looking at trying to buy a long range lens for shooting animals and nature. I'm kinda new to photography and am not sure which brand or size I should be looking for. What features are important and what will I get from different price points? I also would like to get a macro lens for really close shots — is that possible with the same lens? I have a nikon d3000.

  • I've edited the question to be more general; hopefully it can serve as guidance for people with this question without getting into the murky waters of specific shopping advice. – mattdm Dec 15 '14 at 13:33

The general rule of focal length for animals is that too much is never enough. It basically comes down to how much you can afford and are willing to carry. Many nature shots will be in remote places, so lugging the equipment there is a serious consideration. That all said, I'd at least want to go out with a 300 mm lens (relative to a full frame sensor). Even with that, a small bird which is quite close will still look like a small thing in the middle of a big picture.

Macro is a totally different thing from telephoto, so I wouldn't try to get one lens that does both. Even if you can find such a thing, a lens of the size and weight required for distance animals will be unwieldy and difficult to use for macro shots. I've gotten quite passible macro shots with a near-telephoto and extension tubes, although outright macro lenses are easier to handle in the field.

One difference between nature macro photography and other macro photography is that you generally want a little longer macro lens. A common macro subject in nature photography is insects, which tend to buzz off if you try to get too close. Something in the 100-135 mm range helps with that. The downside is that it's tougher to hand-hold without apparent shaking. For things that don't run away, like plants, something around 70 mm is easier to handle.

  • Ya I knew that I would have to get 2 different lenses but thank you for clarification on that....I just didn't know which 2 lenses would be the best as far as mm also which brands are better – TARA HART Dec 15 '14 at 18:34
  • One exception to the macro vs. telephoto lens bit is catadioptric lenses. Some of them can focus close enough to provide near 1:1 capability, though the depth of field is razor-thin. – Mark Dec 16 '14 at 0:20
  • However, mirror lenses tend to have a smaller max. aperture (f/8), which can compromise autofocus performance so not ideal for wildlife, and the cheap-cheap ones may not be terribly sharp. But the donut bokeh is cool. :) – inkista Dec 17 '14 at 21:55

With wildlife, 300mm is considered the minimum focal length you want (if we're really talking wildlife out in the wild, and not backyard semi-tame beasties that aren't shy of humans). 400mm is typically considered a minimum for birds. So, it does in some respects depend on what wildlife you're most typically stalking, in terms of how large and how shy they are. Smaller, shyer animals require longer lenses to fill a frame. And paramount over all this talk of glass, remember that fieldcraft is probably going to be far more important. Your ability to get closer to wildlife without disturbing them is a learned skill and some folks have more talent (or drive to practice) to gain this skill than others (go google "hide" and "ghillie suit"). So again, what focal lengths you'll need rely a great deal on your fieldcraft capabilities. Most of the stunning wildlife images you see were obtained with a lot of sweat, time, patience, and expense--don't expect that picking up a 70-300mm lens is all you need to do to get wildlife shots. But you probably can't expect to get them without one. :)

As a Nikon D3000 shooter, your choices of lenses over 300mm will mostly boil down to either Nikon or Sigma (supposing you have a four-figure budget). If your budget is below $1000, chances are good you can only afford a 70-300mm zoom, and all you have to worry about is whether or not you want to go Nikon or 3rd party. Your main issue, of course, will be finding a lens with AF-S so you'll have autofocus.

Most of these lenses do not let you shoot Macro as well, despite a number of 3rd-party 70-300 lenses being labelled as "macro" lenses. While you can get relatively close, they don't do the true 1:1 magnification of a dedicated macro lens, and if you plan on shooting very small subjects, like bugs or small flowers, chances are good you'll prefer a dedicated macro lens instead.

So, the main lens specs you'll probably be concerned with (aside from cost) are:

  • Focal length. As I stated above, 300mm on a crop body is good for larger or less-shy wildlife. But if you're thinking about small birds that aren't in the backyard, then 400mm or longer is more likely to be what you want. And the cost leap will be considerable. Say, from $600 to $1000 (third-party) or $2000 (OEM).

  • Image quality. Sharpness, contrast, and distortion will probably be the main concerns. With longer lenses, you typically don't worry much about vignetting or C/A. Zooms may be slightly softer than primes, but not always, if you can afford the four-figure price tags.

  • Maximum aperture. Wildlife moves fast, and often in low light. But this is going to be the most expensive thing you can go for. f/4 300mm lenses are astronomical. You don't want to see the prices for f/4 at 400mm. Or f/2.8. Think five figures. You may not have a choice of going with f/5.6 or even f/6.3 with third-party lenses for this. But because wildlife tends to be active in the golden hours, and because the longer focal lengths require faster shutter speeds to mitigate camera shake blur, a larger maximum aperture will help widen the possibilities. The 1/focal_length rule of thumb doesn't really restrict you much at 50mm, but at 500mm, it's something completely different.

  • Autofocus speed. No point in having a great, sharp supertelephoto to shoot flitting birds if it can't autofocus fast enough to grab the shot before the bird flies off. However, given that you have a D3000--you're going to have to get an AF-S lens anyway just to have autofocus. But pay attention to this in reviews.

  • Stabilization. If you plan to handhold while you stalk critters (once you go past 400mm, chances are good you have to shoot with a monopod or tripod, simply from the weight), stabilization can help a lot with the shutter speed restrictions the longer focal length will impose upon you. VR, for longer lenses, is worth it.

  • Focus lock. Some of the longer lenses also have a "focus lock" that allows you to tell the lens to ignore a certain portion of the autofocus range in order to speed up focus locking. This can be invaluable if you tend to shoot things that move fast and are always beyond your reach (i.e., birds in flight).

  • Size/Weight. The longer or faster the lens, the bigger and heavier it gets. Some folks claim they can handhold a Sigma 150-500 OS, some folks cannot. But handholding telephotos and supertelephotos does require a certain amount of technique and care that shorter lenses do not. There are special holds you can use (e.g., the machine gun hold, where you place your left hand on your right shoulder, and rest the lens on your left elbow), as well as a plethora of other ways (beanbags, monopods, tripods, resting on fence rails, your knee), etc. to help with stabilization.

There are a number of guides to selecting lenses on the web -- you should read one or more to familiarize yourself with lens terminology. One you could start with is this one from gizmag.com.

Briefly, like many engineering endeavors, designing a lens (and choosing which to buy) is a matter of tradeoffs. You want to build (or buy) the best product possible, but that means weighing factors like optical quality and light gathering ability against practical matters like cost, size, and weight.

Factors you'll probably want to look at include:

  • sharpness: How sharp, or focussed, is the image at given focal length?
  • speed: What is the maximum aperture (i.e. lowest f-number)? Larger apertures allow more light through the lens, which lets you use shorter shutter speeds. That helps minimize blurring due to camera shake or subject movement.
  • cost: Everyone has a budget to live with.
  • size/weight: A large, heavy lens can be impractical on a long hike, for example.

Other factors that are also important include chromatic aberration, distortion, build quality, image stabilization, special coatings that help to keep the front and back elements clean or to reduce internal reflections, and whether the lens itself can be mounted to a tripod.

To @Caleb's answer I would add:

  • the accuracy and speed of the focussing mechanism.

  • How quiet the focussing mechanism is.

Most lenses are accurate and focus precisely, but they do it at varying speeds. For example, the Nikon 55-300mm AF-S f/4.5-f/5.6 was a nice lens for portraiture and relatively slow moving objects but not animals because: 1) the focussing mechanism was slow, and 2) at the telephoto end it would sometimes not be able to focus at all until zoomed out.

The Nikon 70-300mm is a bit more money, but is probably better suited to animal photography because the focussing mechanism is both fast and quiet.
