Stabilization None
Type Lens
Weight 0.7

The Lensbaby LM-10 ($69.95) is an add-on lens for smartphones that captures images with what's become known as the Lensbaby Effect—a sharp center area surrounded by extreme blur. It attaches to your phone with the help of magnets and an adhesive still disc and works with a free app that allows you to move the sweet spot around, adjust exposure, and record video. It's a lot of fun, and relatively inexpensive, but the magnetic system causes problems when used in conjunction with the iPhone 6 Plus. If you don't use a 6 Plus, and enjoy the look of Lensbaby images, it's a highly recommended add-on for your phone.

Design and Features

The LM-10 ( at Amazon)  itself is a small tube, roughly 1.5 inches in height and less than in inch in terms of diameter. It's light, just 0.8-ounce, and includes magnetic connections on both sides. Its symmetrical optical design means that you won't have to worry about which is the entrance pupil and which is the exit pupil; it can attach in either orientation. A lens cap, with elastic connecting the front and rear covers and a small string that makes it easy to attach the LM-10 to a keychain, is included in the package, as is an alcohol wipe for cleaning the surface of your phone around the lens, and a set of adhesive discs.

You'll need to place one of the discs around your smartphone's rear camera lens before getting started with the LM-10. The discs fit around the lens of most Android smartphones, as well as the iPhone 4S, 5, 5S, 5C, 6, and 6 Plus. Lensbaby also makes a removable mount for select iPhones; for $9.95 you can get one that's compatible with the iPhone 5/5S, 6, or 6 Plus. The mount is a good alternative to using the discs, as it's easily removable and its design ensures that it's perfectly centered around the lens.

I tested the LM-10 with one of these chips and the iPhone 6 Plus. As much as I love the look of the images and video that it's able to capture, I can't recommend the LM-10 if you're an iPhone 6 Plus owner. It includes an optical stabilization system that's absent from other iPhones, and magnets can seriously interfere with it. It didn't happen all the time, but there were several occasions where I mounted the LM-10 on the 6 Plus and the stabilization system simply went crazy, moving the sensor around erratically. I don't know if this is something that can do permanent damage to a phone, but it's not a risk I recommend taking. Nor does Apple; it released a support document that advises against using magnetic lens attachments with the iPhone 6 Plus.

Lensbaby LM-10 : Smartphone App

But if you've got almost any other modern smartphone, you've got no worries in regards to the magnets. The free Lensbaby app for iOS and Android (it requires Jelly Bean at a minimum) is required to make use of the LM-10. The app includes a number of controls, including a slider on the left that adjusts sharpness (available on iOS only), white balance lock, rule of thirds grid overlay toggle, spot metering toggle, contrast adjustment, and focus lock.

Lensbaby LM-10 : Sample Image

When shooting stills you have two options for an angle of view. The centered sweet spot covers a wide angle of coverage, but doesn't give you any control over where the area of sharpness is, other than moving the camera. Double tapping the screen switches to an adjustable sweet spot. The field of view is narrowed, but you're able to frame images with off-center compositions when using it in this way. There were times that I wanted to move the spot a little further to the edge of the frame but the app wouldn't let me; some cropping after capture is required in those situations. The app also supports video recording. You're locked into using a centered sweet spot when recording video.

The app is light on filters; it just includes Monochrome and Sepia. You can use any app on your smartphone if you want to give images a filtered look—I tend to use VSCO Cam for still images destined for Instagram, but stick to Instagram's built-in filters when posting a video clip. And, if you really want to, you can always copy images from your phone to your home computer and edit using Lightroom or another photo workflow application, but the LM-10 is more geared toward mobile photographers living in a smartphone ecosystem.

Conclusions

I'm a fan of the Lensbaby look when used for the right photo. The LM-10 delivers the same look as a Lensbaby SLR lens and optic pair, like the Composer Pro ($340.76 at Amazon) and Sweet 50 Optic ($119.95 at Amazon) , but it does it with your phone's camera and for a lot less money. You do lose some versatility—you can't narrow the aperture of the LM-10 to increase the size of the sweet spot as you can with an SLR Lensbaby—and a smartphone camera is no match for an SLR int terms of image quality.

Whether you're a smartphone photographer who has longed to capture images with the unique viewpoint that a Lensbaby provides, or a seasoned Lensbaby SLR shooter with a desire to get the same look from your smartphone, the LM-10 is an excellent add-on lens for your smartphone. I do recommend getting a mounting clip if you have an iPhone; it only adds $10 to the price and seems a bit more secure than the adhesive discs that ship with the LM-10. iPhone 6 Plus users should take a pass on the LM-10 due to the interference it can cause to the phone's optical image stabilization system. That's a downer, as the 6 Plus's big screen is great for photo editing. But if you've got any other compatible phone, I recommend the LM-10 highly.

My Experience

Images, and the devices that capture them, are my focus. I've covered cameras at PCMag for the past 14 years, which has given me a front row seat for the changeover from DSLRs to mirrorless cameras, the smartphone camera revolution, and the emergence of drones for aerial imaging. I have extensive experience with every major mirrorless and SLR system, and am also comfortable using point-and-shoot and action cameras. As a Part 107 Certified drone pilot, I’m licensed to fly unmanned aircraft systems (UAS) for commercial and editorial purposes, and am knowledgeable about federal rules and regulations regarding drones.

The Technology I Use

I use all of the major camera systems on a regular basis, swapping between Canon, Fujifilm, L-Mount, Micro Four Thirds, Nikon, and Sony systems. I still find time to use Leica M rangefinders and Pentax SLRs on occasion, too. I keep an iPhone 13 in my pocket for the rare occasions I'm not carrying a camera.

I'm not a brand-specific photographer. For product review photos, I swap between a Canon EOS R5 and a Sony a7R IV. I use Flashpoint and Godox TTL lights and Peak Design tripods, and I most often reach for a Think Tank or Peak Design backpack to carry equipment.

When it comes to computers, I'm an unapologetic Mac person and have been for the past 20 years. I write in Pages and use Numbers for spreadsheets. I currently swap between an Intel i9 MacBook Pro and an Apple Silicon Mac Studio for writing and use a calibrated BenQ 32.5-inch with the Studio for photo and video editing. I rely on a LaCie 6big RAID for media storage. I also keep a PC around for gaming, but please don't tell my Macs about it; they'll get jealous.

I split time between several different software apps depending on the type of editing I'm doing. For Raw image processing, Adobe Photoshop Lightroom Classic is my standard. I pair it with a LoupeDeck CT console to supplement my keyboard and trackpad, and I lean on RNI All Films 5 presets when I want to give an image a film look. I use Apple Final Cut Pro for video editing.

My first digital camera was the Canon PowerShot Elph S200, and my first DSLR was the Pentax *ist DL. I have a soft spot for antique film gear. I still use a 1950 vintage Rolleiflex Automat TLR and love trying mid-century Leica lenses on film and digital alike. I mainly use whatever's in front of me for review for digital snaps, but I pick up either my Leica M Typ 240 or Pentax K-3 III Monochrome when I want to step away from review work. In my downtime, I enjoy bird watching, reading, video games, and both good and bad movies, especially in the sci-fi and horror genres.
