Also, the alignment must be impeccable, which is not easy, given the aforementioned small diameter and small numerical aperture of single-mode fibers. Another effect of their small numerical aperture is that single-mode fibers cannot be bent as much before losing the signal.

I only use the wireless connection as a remote trigger, combined with live view when trying to shoot insects on flowers and not scaring them away with my presence ( the insects not the flowers ) And just purely as a remote when I place my tripod in the water and don’t want to make ripples in the water with my movement.

Do you know if it’s transferring the RAW files or just tiny preview jpegs? I think for a long time it only did the later but maybe it’s better now.

If you’re concerned about battery usage while keeping Bluetooth active, activate the Airplane mode on your camera. This turns off all wireless connections at once, conserving battery life. The beauty of Bluetooth lies in its ability to re-establish the connection automatically once Airplane mode is deactivated.

For those whose cameras support wireless connections, I encourage you to explore this functionality. Establish connections, familiarize yourself with the setup, and learn how to make the use of them. At some point, you might find yourself in a situation where wireless connections prove remarkably advantageous or discover uses you hadn't considered before.

Transferring images to your smartphone might prove useful if you intend to share them on social media or perform post-processing on your smartphone. Yet, this method strikes me as labor-intensive. The process involves taking a photo with your camera, switching to your smartphone, opening the image in an app, applying post-processing, and finally sharing the photo. Why not simply take the picture using your smartphone in the first place? It's a more straightforward, time-saving, and often a user-friendly approach.

But, just like a guitar string can only vibrate in certain shapes because its ends are fixed, only certain specific energy distributions can propagate within the boundaries imposed by an optical fiber. These energy distributions are what we call the allowed light modes.

An important disadvantage of multi-mode fibers is that the different modes have different velocities. Since the different modes making up a signal don't travel at the same speed, the signal gets distorted as more and more distance is traveled.

While not all the available wireless connection options are equally beneficial, having these choices at your disposal is valuable. Even if you personally don't find them useful, others might find them indispensable. Ultimately, the presence of these options provides flexibility without imposing an obligation to use them.

With my Sonys if it doesn't connect on the first try it may take 10-15 attempts to connect. Then it will work unless something goes to sleep, the phone rings or a dog barks at a cat... It is a great idea but I can't use it on a job.

This means that for a given wavelength, single-mode fiber cores will typically have a small radius and numerical aperture.

Because they have a bigger core, and the max input angle is larger, it is easier to launch light into a multi-mode optical fiber.

Personally, I can’t see the benefit of transferring captured images directly to a smartphone. Storing raw or JPEG files on a limited smartphone memory doesn't make much sense. If you have valid reasons for doing so, I'd be interested to hear about them.

Enabling the shutter remotely via a wireless connection is a great option. This is particularly true when you want to include yourself in the frame. With this feature, you're no longer bound by the 10-second self-timer for positioning yourself. Additionally, the 2-second or 5-second self-timer options provide enough time to conceal the smartphone out of sight.

In my opinion, this functionality is genuinely useful. You need to keep the effective range between the smartphone and camera in mind, because there is a limit. If that becomes an issue, a wireless radio trigger serves as a more practical alternative. On top of that, it's easier to use, potentially quicker, and requires less attention to find the trigger button. Nevertheless, there are situations where the built-in wireless connection's convenience shines.

Thankfully, improvements in smartphone apps and camera software have made the process more streamlined than ever before. Even so, setting up a wireless connection can be challenging nevertheless.

Because there is only one mode, there can be no intermodal dispersion. This means that even over long distances, the signal of a single-mode fiber will remain clear.

If your camera supports Bluetooth, which is likely the case for most modern cameras, setting up both Bluetooth and Wi-Fi connections is advisable. The camera tends to connect more seamlessly through Bluetooth, and if greater bandwidth is required, it will automatically switch to Wi-Fi. This approach offers improved reliability and faster performance.

Optical fibers can be tweaked to accept more or less of these modes. Allowing more modes generally makes the fiber easier to work with, at the cost of output beam quality.

Initially, I was skeptical about the usefulness of wireless connections between smartphones and cameras. However, my perspective has shifted, particularly after extensively using them for remote live view photography. This functionality proved indispensable in such scenarios. There was, however, one challenge, establishing a stable Wi-Fi connection.

Laser specifications change over time for many reasons and it causes problems accross all industries. Learn about how laser output measurement solves numerous problems in YOUR industry. Download the guide below.

For those who've never used their camera's wireless connectivity before, the question of its benefits might arise. I myself had these doubts initially, but I've come to realize that it can indeed be quite useful, sometimes even essential. However, there are instances where alternative methods might be more convenient.

When I need GPS data for my photos, I prefer using an external GPS logger. This could be a smartphone app or a standalone GPS logger like the Columbus P10 Pro. It offers additional functionalities, and adding GPS data to your photos is a straightforward process in software like Lightroom Classic.

The wireless capabilities of contemporary cameras are becoming increasingly sophisticated with each new model release. Personally, I've observed significant improvements in the way these connections operate, at least in the context of my Canon cameras. However, I must admit that I haven't extensively tested this feature with all the other camera brands I've reviewed so far.

If you're interested in adding GPS coordinates to your photos, the wireless connection between your camera and smartphone enables the camera to gather GPS data, which is then automatically embedded in the image's metadata. Keep in mind that for this feature to work, your smartphone needs to remain continuously connected. Bluetooth is likely the best option, although a Wi-Fi connection could also suffice. While this could impact your battery life, the effect might be less significant compared to using a built-in GPS system.

I've used remote with my Nikon D7500 while taking sunsets and it worked well. It would be nice if video could be started and stopped as well

where  is the wavelength,  is the radius of the fiber core, and NA is the numerical aperture (quantifies the max angle of acceptance of input light).

Combining Bluetooth and Wi-Fi turned out to be a great solution, provided your camera supports both. Unfortunately, good documentation on wireless connection setup is often lacking, and discovering the most efficient and user-friendly way to connect your smartphone and camera requires some research.

Beams with more modes and lower beam quality can travel within multi-mode fibers. This opens the door to using more light sources, including sources of higher-power light, like diode stacks.

Feel free to share your experiences and uses of wireless connections between cameras and smartphones or other devices in the comments below. I'm eager to learn about your insights.

My experience with the Fujifilm X100T has been somewhat challenging. Establishing a connection between my smartphone and the camera via Wi-Fi often required a considerable amount of effort. Even when successful, there was no guarantee that the connection would work smoothly a second time around.

Transferring photos to your smartphone is another possibility. Both raw or JPEG files depending on the app, and some cameras even support FTP connections, enabling you to save images on a server, computer, or smart device. However, beyond studio environments, I struggle to see the benefits of wireless file transfer options. Even for studio photography, there might be more efficient alternatives for transferring images, like tethered shooting.

For optimal transmission, the incident laser light must have a high beam quality (M2 near 1) and be appropriately mode-matched with the fiber.

Being able to shoot and have the images jump straight to a phone (wireless tethering, so to speak) beats shooting with the phone itself if you prefer the image quality a camera offers, and lets you share to social or elsewhere without the step of later connecting to the camera, browsing the tiny thumbnails in a sluggish interface, and then downloading only those you think you want (but might be out of focus, hard to tell from the tiny thumbs). Lightroom for mobile is full featured and a lot of people prefer the editing interface on their phone anyway. Yes, storage is obviously the big limitation, but if you’re okay with that the camera and apps should facilitate it.

I used the app on my iPad when travelling to go through the images and select the images to be deleted. In the meantime my eyesight changed so I now use the backside screen of my cameras without glasses, because it's much simpler. As the Leica Q2 doesn't have an articulating screen for selfies I once used the app, but it's ... rather stupid, so I went back to using my smartphone.

This functionality proves beneficial for various photography styles, including macro photography or situations where the camera is positioned out of easy reach. For me personally, this is the most useful wireless connection feature.

In my experience with the Canon EOS 5D Mark IV, establishing a reliable Wi-Fi connection proved challenging at times. Particularly when a known Wi-Fi network was available, my smartphone seemed to prioritize that network over the camera's. However, when it did work, it worked flawlessly when I used the camera mounted on a pole.

Using wireless connections involves continuous communication between the camera and smartphone, which can drain the battery rapidly. This is a crucial consideration, and if you frequently use wireless connections, having a spare battery on hand might be wise.

I've gotten used to making connections to Sony cameras. Not as streamlined as these connections should be, but not bad after you have done it a few times. Olympus isn't too bad. My one Panasonic camera is a pain. I go through the steps and the app says it is connecting, but takes a long time, assuming it ever connects.

One step up from a simple remote trigger is remote live view. There are instances when I need to control the camera remotely, such as when it's mounted on a pole at a height of two to eight meters. This is when I find the remote live view function of the Canon app invaluable. It allows me to preview the shot and adjust exposure settings as needed.

I like Cascable app. I tried with cable to my iPhone. That’s my choice, and Capture One in studio, with cable. Both offer support wireless.

Fibers with a v-number below approximately 2.405 can support only the fundamental mode. For step-index fibers, the v-number is given by:

So far, all I get is a 1616 x 1080 jpeg when it automatically sends to phone. Sending to phone afterwards I get a 6000 x 4000 jpeg, but my phone might not be able to handle a RAW file transferred that way. The app does say it will send RAW or HEIF if the phone is capable.

You mentioned a good point. My cameras only take a single memory card. I knew that using the Sony app as remote would upload an image to the phone automatically. A little slow since the app pauses for the upload. Then I tried something different. I used the camera in the normal manner while connected to the app in remote control mode, and I found it still sent a copy of the file to the phone. Now my phone acts as backup storage.

I’ve heard similar complaints by photographers using Sony and Nikon cameras. While I'm more acquainted with connecting my smartphone to a Canon camera, I've encountered some peculiar issues with it as well.

Stability of the connection is another factor to keep in mind. I've noticed that something as simple as a sleep mode or standby setting can disrupt the connection, especially with Wi-Fi. Also, if your smartphone detects a known Wi-Fi signal that has more signal strength, it might switch over without warning. If this happens, it might prove a lot of effort to restore the connection.
