This review of the Moment Tele 58mm cellphone lens is long overdue. When I started developing the RitchieCam iPhone camera app about a year ago, I figured it would be a good idea to get some external lenses for my iPhone 11, which would come in handy when needing to capture the example pictures. While there are a number of companies that offer lenses that can be attached to your cellphone, the Moment offerings stood out to me as the “better” option, so that’s what I chose.

To use Moment’s lenses, you must also use their phone case, because that’s how the lenses mount to your phone. They have a case for many phone makes and models, so there’s a good chance there’s one available for your device. The case is good quality, and has survived nearly a year of heavy use and abuse. I cannot tell you how many times that I’ve dropped my phone and thought it was done for, yet it survived unscathed, without even a scratch! While I’m sure there are cases that offer more protection, I’m pretty darn impressed with how good the Moment case has been.

One cool thing about the Moment case is that it has the “MagSafe” stuff built-in. I have this tripod-mount accessory that attaches to the case (via magnetism), which has come in handy a number of times. It’s a really good method to mount your cellphone to a tripod, if that’s something you do. There are a number of other accessories that you can buy that also use magnets to attach to your case, but the only one that I personally have used is that tripod accessory.

I had never used an external lens before with a cellphone, so I was definitely a novice when I started—I didn’t really realize how it all worked. On my iPhone 11 case, the lens mounts only over the main camera. The iPhone 11 has two rear facing cameras: 1x (26mm full-frame-equivalent) and 0.5x (13mm full-frame-equivalent). The Moment lenses cannot mount over the 13mm lens, only over the 26mm lens.

I have two Moment lenses: 18mm and 58mm. The Moment lenses are actually “conversion” lenses, and the millimeter numbers don’t actually mean anything. The 18mm is a 0.5x wide conversion lens, and the 58mm is a 2x tele conversion lens. Using the 18mm lens on the 26mm camera actually makes it 13mm, which is the same focal length of the second camera. In other words, the 18mm lens is pointless for the iPhone 11; however, I’m sure it makes sense for other cellphones. The 58mm lens makes the main camera 52mm, which is a very useful focal-length. The focal-length that these lenses will be on your cellphone depends on the focal-length of the cameras on your cellphone (either times by .5 for the 18mm lens or times by 2 for the 58mm lens). Clear as mud? I think if Moment had simply called the one lens 2x teleconverter and the other .5x wide-converter (instead of using millimeter numbers) it would save a lot of confusion. As you can imagine, the Moment Tele 58mm lens is the one that I used by far the most.

Initially I was disappointed by these lenses. I think my expectations were significantly askew. I figured that I’d be impressed by the image quality when using these lenses vs. not using them; however, the image quality will never be greater than that of the lens permanently attached to your cellphone. These lenses won’t improve on what the manufacturer installed on your device. Instead, what you get is either a longer or more wide-angle focal length without a loss in image quality. It’s much better to use the 58mm lens than “zoom by cropping” (a.k.a. digital zoom). The image quality produced by these lenses is determined mostly by the image quality produced by your phone.

The reason to use the Moment Tele 58mm lens is to double the reach of your built-in cellphone lens without degrading the image quality (or, if it does degrade the image quality, it’s extraordinarily minimal and not really noticeable). That’s what this lens does, and it does it well. It doesn’t do much else, so keep your expectations in check.

When I carry the 58mm lens with me, I get three focal-length options on my iPhone 11: 13mm (using the 0.5x camera), 26mm (using the 1x camera without the Moment lens), and 52mm (using the 1x camera with the 58mm lens). Those are all excellent focal-lengths to have available. While I prefer to use my Fujifilm cameras over my cellphone, as Chase Jarvis coined, the best camera is the one you have with you, which is sometimes my cellphone. When I do use my cellphone for photography, I appreciate having the Moment Tele 58mm lens, because it affords me additional flexibility.

I said two paragraphs ago that this lens “doesn’t do much else” which isn’t completely true. There’s a small amount of pincushion distortion, which, when combined with the distortion in the iPhone 11 camera, can do some weird things to straight lines when photographing brick walls. The solution: don’t photograph brick walls. There’s also some interesting lens flare that shows up sometimes (see picture below), which I personally like, but maybe you won’t, depending on how you feel about lens flare. The Moment lens is also softer in the corners than the 1x iPhone camera.

The build quality of the Moment Tele 58mm lens is excellent, made of metal and glass. It has six elements in four groups, and the glass has multi-layered anti-reflective coating. It comes with a lens cap and carrying bag. The lens is small enough that you can easily take it with you, although when attached to the phone, it’s unlikely that the phone will fit into your pocket (unless you have particularly large pockets).

I have used the Moment Tele 58mm lens for nearly a year now. It’s not an essential cellphone accessory, but it’s certainly nice to have around. I found the lens and the Moment case (that you are required to have in order to use the lens)—plus the tripod-mount accessory—to be useful to me. If you do a lot of cellphone photography, you might want to take a closer look at these Moment products, and consider if they might be useful to you, too. Like a lot of things in the photography world, these products are not cheap, but if you think you’ll use them regularly, they might very well be worth the cost. The best place to find these products is on Moment’s website.
