Choosing Lenses

Choosing lenses can be confusing with so many things to take into consideration... Focal length, maximum aperture, weight, price, prime vs. zoom, etc. I'm going to try and break things down as best I can and hopefully give you a better understanding of all this so you can make a more informed decision on what to purchase.

What Do All Those Numbers Mean?
When looking at lenses, you’re going to see lots of different numbers. The first ones are going to be followed by mm. So, 24-70mm or 70-200mm or 16-35mm or whatever. This is the focal length. The smaller the number, the “wider” the lens, so these are called wide angle lenses. The bigger the number, the “longer” the lens, and these are called telephoto lenses once they're 70mm or more. After these numbers, you’ll see some that start with f/. So, f/2.8, f/4, f/3.5-5.6, etc. This is the maximum f-stop or aperture (the terms are relatively interchangeable). The lower the number, the “faster” the lens, aka glass. The bigger the number, the “slower” the lens/glass. Let’s dig into these two sets of numbers a little deeper…

Zoom vs. Prime Lenses
If you see two numbers, like 24-70mm, on a lens, that means it’s a zoom lens. These lenses let you get closer to or further away from your subject without physically moving yourself to do so. If there’s only one number, like 35mm, this means it’s a fixed focal length, or “prime," lens. So if you want to get closer or further away from your subject, you have to “zoom with your feet,” as Joe McNally says.

Fixed vs. Variable Aperture
If you see one number, like f/2.8, on a lens, that means it’s a fixed aperture lens. All prime lenses are fixed aperture, as well as some zoom lenses. This means that no matter what focal length the lens is at, your maximum aperture will remain the same. If you see two numbers, like f/3.5-5.6, then it’s a variable aperture lens. This means that as you zoom the lens in or back out, the maximum aperture is going to change. If I’m using an 18-135mm f/3.5-5.6 lens, the maximum aperture will change from f/3.5 when I’m at 18mm and then incrementally increase to f/5.6 as I zoom to 135mm.

Putting It All Together
While zoom lenses can be fast, prime lenses tend to be faster. For example, the Canon 24-70mm f/2.8 is around $1750 currently. But if I wanted a faster fixed lens, I have lots of options at different price points. I can get a 35mm f/2 lens for around $600 or the original f/1.4 version for around $1000 (there’s a new version that is priced around $1800). Lots of 35mm options for Nikon shooters as well. Or I can look at the Canon 50mm lineup and go anywhere from $110 for the f/1.8 version to $350 for the f/1.4 version  or even tack on an extra grand and spend $1350 for the f/1.2 version. Again, Nikon also has various 50mm options.

But, you have to take into account what kinds of shooting situations you find yourself in most often. Can you zoom with your feet? If so, then prime lenses might be the best for you. If not and you’re in situations with limited space (say, a photo pit at a concert), then zoom lenses might be best. And what camera are you shooting with? Does it handle high ISO situations pretty well? If so, you might prefer shooting at a higher ISO with a slower lens to spending more money on a faster lens.

The "Standard" Pro Setup
A lot of working pros have what is referred to as the "trinity" of lenses. For Canon shooters, that's the 11-24mm f/4 or 16-35mm f/2.8, 24-70mm f/2.8, and 70-200mm f/2.8. For Nikon shooters, it's the 14-24mm f/2.8, 24-70mm f/2.8, and 70-200mm f/2.8. Why these lenses? They're going to cover you really well in most situations all the way from super wide to telephoto, and they're all pretty fast lenses so they're helpful if you're shooting in low light situations. These are also high end lenses, so they're going to put a dent in your wallet. Worth it if you need it, but...

Saving Money
Do you really need to spring for the most expensive options? Unless you’re shooting in low light situations, you probably don’t. For example, my buddy Peter Hurley does the vast majority of his work in the studio where he’s controlling the light, so he uses the Canon 70-200mm f/4 lens instead of the 70-200mm f/2.8. What’s the difference? About $1350, a stop of light, and nearly half the weight.

So, for Peter the f/4 version makes more sense because if he needs more light, he’s in his studio and can adjust the power. And he never shoots at f/2.8, so why spend all that extra money and add twice the weight to what he’s holding and carrying around in his gear bag? Nikon makes 70-200mm f/4 and 70-200mm f/2.8 lenses as well. The price difference isn’t as big as Canon’s, but $600 is still a lot of money!

But for someone like me who does concert and behind the scenes work, I need that extra stop of light that the f/2.8 version gives me. Could I get by with the f/4? A lot of the time, yes. But if I’m in a small venue with bad lighting trying to shoot a high-energy artist that doesn’t allow flash, I’m going to be hard pressed to get a single shot that isn’t blurry, even at 25,600 ISO. My wallet may be thinner and my shoulders may be a bit more sore at the end of the night, but at least the images are sharp!

Full Frame vs. Crop Frame
One last thing to consider is whether you're shooting on a full frame or a crop sensor camera. Most of the lower-end DSLRs are crop sensors, meaning they are smaller than full frame sensors. Some lenses are made to only cover the size of the crop sensor, so if you use them on a full frame camera, your image will be cropped and you'll lose some of your resolution, as you see below on the right.

However, if you purchase full frame lenses, you can use them on any camera without a loss of image resolution. If you do use them on a crop sensor camera, then they effectively become a "longer" lens because of the smaller sensor size. So what was a 70-200mm lens becomes an approximately 105-300mm lens, depending on the exact size of the crop sensor.

So which should you buy? If you never plan on upgrading to a full-frame camera and alway sticking with a crop sensor camera, then you can save some money and only buy crop lenses. But if you think you might make the jump to a full frame camera, it's up to you if you want to save in the short term then buy new lenses when you make the jump, or go ahead and invest now to save yourself the hassle later.

On Canon, crop lenses are indicated by the letters EF-S (full frame lenses are just EF), and Nikon indicates their crop lenses with the letters DX (full frame lenses are FX). And to find out if your camera body is full frame or crop sensor, just look up the specs online and it should be one of the first things listed. Canon crop sensors will say APS-C sensor (full frame will just say full frame), and Nikon crop sensors will say DX-Format while full frame will say FX-Format.

Conclusion
I hope this helps you when choosing which lenses to buy. When in doubt, you can always rent lenses (and other gear) from places like LensProToGoBorrow Lenses, or Lens Rentals to try them before you buy them.

The Rebirth of Underoath, Pt. 3 - Tech Rehearsals

Tech rehearsals are when artists go to a rehearsal space (sometimes a space dedicated to just this purpose, sometimes a smaller venue that happens to be available for the time they need to dial everything in), so they can set up their full production (video screens, lights, and all the other things that go into a show) and run through their set to work out any kinks or technical difficulties before they play in front of an audience.

So for the two days between the "secret show" and their first official show of the tour, that's what they did. The first day was mostly getting everything set up and plugged in and wired and rigged up correctly. Just enough for the band to run through and make sure all their gear is synced up properly.

Since the lights and video screens were still in the process of being fully set up, I decided to treat the first day's shoot as behind the scenes, and thus converted these image to black and white.

When I arrived at day two of tech rehearsal, the full production was up and running, so it was kind of like my own private preview of the concert! With the band allowing me access to cover these days, I was able to get some shots that would just be darn near impossible to get during the actual concert.

They're not going to put up with a photographer running around the stage the entire time they're trying to perform, no matter how good of a friend they may be. But that's basically what I was able to do here.

Well, it wasn't really my own private preview... Some of the band members' wives and kids were on hand to see their husbands/dads at work too ;-)

Not your typical "bring your kids to work day," right?!

And now that tech rehearsals are over, it's time to play the gig.

The Rebirth of Underoath, Pt. 2 - Secret Show

While many of the band's shows on the tour are already sold out, including their first show tonight at an approximately 2,000-person capacity venue, they announced a "secret show" at a 400-person capacity venue in Tampa on Sunday night. This show was $10 at the door on a first come, first serve basis; and once it was full, it was full.

The venues they normally play at have big stages and a barricade/photo pit between the crowd and the band. Not so at this one, as you can see in the video below:

This time I was armed with the same Canon 1DX bodies and 70-200mm f/2.8, but this time I had the 11-24mm f/4 and 24-70mm f/2.8 lenses as well. The latter two ended up being the only ones I used during Underoath's set since it was such a small venue. I started off right in front of the stage in the crowd during the opening bands and was fine. But once Underoath took the stage, I only lasted for two songs before I escaped the flying bodies and pummeling from the fans to try to catch my breath and make my torso cease feeling pain.

As my friend Andrew described seeing me upon my escape, "I wish I would have snapped a photo of you when you came up off the floor at the beginning. It looked like a cartoon version of someone that had just been caught in a tornado, it was great! I'll have that image burned into my head for ever, I was sooo worried for a second and then processed what happened and just immediately burst out laughing."

From then on, I shot from the side and back of the stage where the rest of the friends and family of the band were standing. But they weren't standing there for long. Most of them wound up diving into the crowd from the stage before the show was over! This vantage point allowed me to get shots of the band up close and personal that aren't usually possible at a larger venue. Plus, just due to the nature of the show, I was actually able to get out on the stage and shoot a few short bursts then get out of the way again.

To say it was a crazy night would be an understatement, but it was an absolute blast and one to remember for sure.

This show allowed the band to perform in front of a crowd for the first time since their last tour three years ago and allowed them to get back into that groove again. Now that they've got the playing and energy parts down, time for "tech rehearsals..."

The Rebirth of Underoath, Pt. 1 - Practice

A few years ago, the band Underoath played what was then to be their final tour ever as a band. They did their farewell tour, made a documentary about the whole thing, and then each of the members moved on to the next phase in their lives, but they all remained friends after this.

Fast forward to late last year, and they're all on a group text joking about what it would be like to tour again. Then the joking turned serious and, after much discussion and figuring out logistics, they decided to reunite to tour once again and play their two most popular albums, They're Only Chasing Safety and Define The Great Line, back to back on the Underoath Rebirth Tour.

The first official show of the tour was in St. Petersburg, Florida at Jannus Live, the same venue where they played the final show of their last tour. And the band has allowed me to document some behind the scenes images of the events leading up to this show.

Before that, they invited me to come out to their practice space and document one of their final practices before taking the stage once again. The space is a storage unit, lit solely by one fluorescent light inside, and some typical parking lot lights outside. Thankfully, I had two Canon 1DX bodies at my side, coupled with the 70-200mm f/2.8 and 16-35mm f/2.8 lenses, to handle the high ISO situation.

As the band practiced, I tried to cover them from every angle I could think of while staying out of their way as best as possible. During this time, they're focused on making sure they remember how to play the songs and are all on the same page with everything rather than performing. So while they're into it, it's definitely a lower energy situation than a live performance.

For post processing, I prefer converting behind the scenes/documentary images to black and white. I just think it gives them a more timeless feel, and helps differentiate the images from my live concert work. In this particular case, I used Macphun's Tonality Pro plug-in to do the black and white conversions. I started with the software's Bold Contrast preset, then tweaked it to best fit these images and created my own preset. Once I had that in place, I did a batch process of the images and ran my preset at 50% so the images didn't look over-processed. This gave the shots a nice but gritty look that almost made them feel like they were shot on film.

Next up, a secret show that was pure craziness...
