Purchasing Your Next Lens


No matter how many lenses a photographer has, there’s always another one that we long for. There are so many options out there that choosing your next lens can be a confusing task. We're going to help you choose the best lens to fit your specific needs.

The first question you have to ask yourself is, “What do I need that my current lens doesn’t give me?” Your answer is most likely going to fall into one of two categories: speed or zoom. Let’s take a look at the speed problem first and figure out what lenses can solve it for you.        

Fast Prime Lenses

Most kit lenses have variable apertures that start at f/3.5 and close up to f/5.6 as you zoom in to the longer side of the lens. This is fine if you’re shooting outdoors on a sunny day, or indoors with a flash or bright lights, but not suitable for low-light situations. For that, you’re going to need a fast lens.

So, what is a “fast” lens? Fast lenses generally have an aperture of f/2.8 or larger. The larger the aperture, the more light the lens allows in, so fast lenses are great for low-light conditions. A prime lens is a fixed focal length lens, so the lens doesn’t do the zooming, your legs do. Prime lenses often offer larger apertures than zoom lenses, and are ideal for shooting video with a DSLR camera.

One of the most common second-lens choices that photographers make is the 50mm f/1.8. It’s a relatively inexpensive lens that can be wide enough to shoot a group of people in a room and also long enough to shoot headshots. The larger aperture means shorter depth of field, which gives your photos nice bokeh (that blurred-out background look that isolates your subject and looks great).

50mm on a crop-sensor camera (with a 1.5x crop factor, such as APS-C) is equivalent to 75mm on a full-frame camera, so if you think 50mm might not be quite wide enough for your camera, a 35mm lens might be a better option. It’s a little wider, making it better for group portraits in tight spaces without the distortion of even wider lenses. There are also other fast lenses that are even wider, like the 28mm and 24mm f/1.8 lenses. 

On the other hand, if you want a fast lens that is longer, for portraits or shooting objects farther away, the 85mm f/1.8 lenses might be for you. Longer lenses are great for portraits because they offer less distortion and allow you to be farther from your subject.

Telephoto Zoom Lenses

Telephoto lenses are great for photographing birds, sports, theater, or any other subject that is far from your camera. If you find that you’re missing out on shots because you can’t zoom in close enough to your subject, you should probably choose a telephoto lens as your next lens. Maybe you have a kit lens that reaches 200mm, but at f/5.6 your shutter speed is too slow to freeze the movement of your subject. In this case, you need a faster telephoto lens. The most common telephoto zoom lenses are the 70-200mm f/2.8 lenses. They are fast enough to stop action and give you nice bokeh, while keeping your subject sharp. If you have a crop-sensor camera, this will provide about a 105-300mm equivalent on a full-frame camera.

If you don’t need the speed that the f/2.8 lenses offer, some other great choices would be a 70-200mm f/4 or if you need the extra zoom, the 18-300mm or 70-300mm variable-aperture lenses might be your answer.

Another thing to consider, with telephoto lenses especially, is whether or not you need a built-in image stabilizing system. Nikon calls this VR (vibration reduction), Canon calls it IS (image stabilization), Tamron has VC (vibration compensation), and Sigma calls theirs OS (optical stabilization). Whatever you call it, the benefit of having a lens with image stabilization is that you can effectively use a longer shutter speed when shooting without a tripod, giving you sharper images, and making the lens more effective in low-light situations.

Wide Zoom Lenses

If your answer to the “What do I need that my current lens doesn’t give me?” question is that you need to squeeze more people into your frame, or you need to capture more of a landscape in your photos, then a wide lens should be your next choice. 

We've briefly mentioned the 28mm and 24mm focal lengths, which are solid prime lenses, but often times with a second lens you might want more versatility, such as that found in wide zoom lenses. There are many different zoom lengths available, not only from the main manufacturers, but from Sigma, Tokina, and Tamron as well.  One thing that most photographers will tell you is that when shooting with a zoom lens, most of their shots are at one of the extremes, either the widest or the longest end of the zoom. While I think the Tokina 11-16mm f/2.8 is one of the sharpest super-wide lenses, it doesn’t offer as much of a range as the 12-24mm, 16-35mm, 17-50mm or 24-70mm zooms. This is where you have to decide exactly why you will need this lens. If you’re not exactly sure, the 24-70mm is a good choice, as it will let you shoot both full-length body and headshots. If you don’t need that much of a range, and just want a very wide lens, then the 11-16mm might be your best option.

Macro Lenses

Perhaps you’ve seen some really close-up photos of insects or flowers, and you’ve tried to take them yourself with your kit lens but found that it couldn’t focus. This is because you need a special type of lens that has a very small minimum focus distance, usually called a macro and sometimes a micro lens. These lenses usually focus at a foot or less all the way to infinity, so you can use them for shooting macro photography as well as everyday shots of people, landscapes, or other subjects at any distance. The same choices apply here, whether you need a fast lens or not, and whether you need a wider-angle or telephoto lens.

There are a couple of important things to consider when choosing a macro lens. First, the wider your lens, the closer you’ll need to get to your subject. If you’re shooting flowers, and you want to focus on one flower but also want to get other flowers out of focus in the background, then a wider lens like a 40 or 50mm would work best for you. On the other hand, if you’re trying to shoot moving insects like bumble bees or butterflies, chances are you won’t be able to get close enough to them with a wide lens, so something like an 85mm or longer would be better for you. Also, when you’re shooting with your camera and lens very close to your subject you often cast a shadow, meaning less light, and requiring a faster lens or special ring lights for your camera. If you don’t want to worry about shadows or purchasing flashes, consider a longer macro lens for your camera.

So, we’ve generally covered a lot of ground here. We’ve discussed choosing the lens based on what focal length you need, whether you want a prime lens or a zoom lens, and whether you need a fast lens with a constant aperture or can deal with a slower variable aperture.

Once you figure out exactly what will satisfy your photographic requirements that are as yet unfulfilled, you should be able to make an informed decision confidently, to ensure that your next lens purchase will be the right one for you.

I have a 24-70 mm f2.8 lens and a 300 mm f2.8 lens. At some point, I need a 70-200 mm lens. I seldom need very wide or specialty function like a TS lens.

Great article. Except that you forgot one thing: how to hide your lens purchase from your wife (or significant other).

Lots of options:

1.    Order from B&H and ship to your (trustworthy) neighbor. SO's usually don't pay close attention; you can integrate it into your lens collection.

2.    Order from B&H and ship to you and be upfront; you can't help yourself. SO will melt realizing you can't help yourself.

3.    Order from B&H and ship to you and suffer the consequences if the SO intercepts the shipment. Best option; life is too short!  

Jeb....One other excellent option here: Order the lens you want from B & H and ship it to me. I'll gladly put it to good use and your SO will never know!

Love B&H. I won't buy from any other retailer. Want a real horror story, ask me about ordering a D70 a few yrs back from Adorama and it going to a house across town. Now about ordering that lens. 

Hello! I am going to buy the Canon 70D and appreciate this overview. My trouble in going through with the purchase is deciding which lens/lens kit to get.
Would you please help me understand the package with the EF-S 18-135mm f/3.5-5.6 IS STM Zoom Lens and the Canon EF 70-300mm f/4-5.6 IS USM lens? I thought these two lenses may be a good combo, but now reading the above it sounds like these lenses may actually be very similar. Would you suggest getting one lens or another to start? Would one of these lenses plus another of a lower aperture or prime lens be a better start? Thanks so much!

I have a 5D Mark III from B&H and use the Canon 24-105mm,
35mm, and 85mm lenses on a regular basis. I have had an
Issue where the 24-105mm lens has fallen off the 5D body
and it has happened twice (This has not occurred with either
fixed lens).
Have you heard of others having the 24-105 lens pop off
the camera body? I am very careful whenever I have this lens
on however I am almost afraid to use this zoom now for
fear it will fall off again.
Any help you can provide is appreciated.

I currently have a Canon 6D. I will be going to Africa where I will be shooting wildlife from a distance. What telephoto lens and converter would you recommend? I will also be shooting Victoria Falls which is expected to put off a lot of mist.

We shoot with a Canon 7D and are researching macro lenses. We will primarily be shooting high quality highly detailed food images for our website and product labels. What is the best Canon macro lens for vibrant high detail food photography.

I have a Canon 60D, and my current favorite lens is a f/3.5-5.6 18-200mm zoom. I am a high level amateur, and I have high schoolers involved in band, choir and theater, plus the traveling that we do. I am finding that I need a faster lens to get those concert shots, night-time games and parades, and theater events.
I prefer this lens (with the zoom) because I can be further away and sneak pictures of my kids with the zoom, but so many pics are not coming out well b/c the shutter speed has to be too slow.
Any recommendations, without spending TOO much? and if I do have to save for a while, what would be the best thing?
(and what is with the lenses that have what looks like a bracket on the bottom - are they heavy and need support?)

I have a Canon 5D. I have a Canon EF 50mm f/1.8 II Lens that I love. Only problem, is that I can not take certain photos unless I take a few steps back. Such as taking a pic of someone while only a couple of feet away from them.

What lens would you recommend that I use?

Thank you.

I am amateur and new in photography. Most of my pictures are for family and travel. My camera a Nikon 3100 which consider nice. Comes with kit lens 18-55 and 55-200. I am looking other choices of lens. Maybe a wider lens and versatility. People recommend 18-200 from nikkor. Is a good choice? Which one you recommend?

Hi, I currently have a Nikon D90 with a 18-200 3.5f lens. I am now looking for lens that will allow me to shoot indoors and possibly night pictures without the need of a flash (if possible). Would you be able to go into some detail about a 50mm 1.8f vs 1.4f lens in terms of how much light is needed or how fast of an image would be captured on each?


I have a Canon T1i with a 28-135 mm lens which is good for most situations except for taking pictures at indoor sports events mainly track events,the light situation indoors is not great, would a ef 50 mm 1.8f work if not any sugestions, i can get very close to the track so distance is not an issue.Thanks.

What would be your lens recommendation for indoor sporting events? I need something relatively fast without a huge zoom.

Thanks for the info. I am considering a long zoom with fixed speed at either f/4.0 or f/2.8 for my Nikons D200 & D300. I have the Nikon zoom 85mm - 300mm that works great with ample light. I also have a very old Tamron prime 300mm that, altho all manual, still takes great images, but too is rather slow & have to use a tripod always.
I was also interested in using a tele-extender (2x) with the new lens. What would you recommend for the two Nikons? I looked at the Sigma 200-500mm, but it has variable f-speeds.

Also, if you would, I had no problem using the 300mm Tamron that I originally bought for my first Nikon F on the D200/300s, but I tried to use the 50mm, f/1.4 prime that came with it on my D's, and it wouldn't attach. Any thoughts. Thanks very much.

Hi Eric, I'm just a beginner, but really love photography. I've learnt a lot from you. I'm about to purchase Canon EF 70-200mm f/2.8L USM lens for shooting landscape and other close objects for my school projects. I believe this lens does not have built-in Image Stabilizer. I would ask you the good way to minimize vibration when shooting distant objects. By the way, does this lens fit my Canon 60D? Thank you.

Great information. My question concerns long lenses. I Like shooting nature and wildlife and need a longer lense. I shoot with an 18-270 zoom which is not enough. I know I should buy longer but money is an issue. I was thinking of also getting a tel-extender. What combination would work best for a limited budget?

Very informative. I am a beginner and this will help me decide what lens I would like next. Thank you so much for this article.

This great for someone like me that does not know what to look for, but now I have a better knowledge.

As always good information from B&H. I have a Sigma 18-200 that works fairly well. I do find that at the long end the images are a little soft. I also have a Nikon prime 50mm 1.8 that's great. Yet i am still looking for another lens any suggestions.

This was very good information for a beginner like me

Very informative,
Thankyou very much

A nice article, covering the more typical photographic situations. I was hoping for a discussion of lenses for night photography. I am an amateur with pro-ish aspirations who loves night photography, but I struggle with pixelized photos.

Thanks for the concise summary. I recently went in the opposite direction of an additional lens, to one lens for everything. I am disabled and the additional weight of additional lenses in the bag tires me out. I settled on the EFS 18-200 from Canon, and so far I am quite happy with it.
