Camera Balance: An Often Overlooked But Important Feature
While the broad strokes of what is wanted on a camera usually revolve around the imaging fundamentals -- resolution, ISO performance, AF, et cetera -- there are some functions of camera design that have a significant impact on creating that often can be overlooked. The aspect that I want to discuss today is that of balance.
By balance, I am talking about how the chassis works together with the lens in a way that makes creating more fluid for the photographer. To be honest, this was an issue that hadn’t been on my mind all that much over the years, as I mostly shot camera bodies that had a built-in vertical grip or were medium format and were therefore larger. However, with the emerging dominance of mirrorless bodies, size and weight have come under so much scrutiny, and that has been at a cost of balance.
While not something that would generally impact a hobbyist photographer, for a professional on set with a camera it is like trying to run a race with a sprained ankle. While it is still possible to do a photoshoot successfully, the effort needed to create a photo is increased, and in economies of scale, a few seconds per image can add up by the end of the production.
For a long time, I hadn’t a clue what was the cause of such disruption to my workflow. That is until the day that I got the Canon RF 28-70 f/2L. By most comparisons to other zooms in the same range, this lens is a beast. However, the optical formula makes the balance tradeoff worth it. With such large elements, the burliness of the lens was causing me to dip the Canon EOS R I was using it with, as I didn’t have a vertical grip on it.
With the smaller chassis of the EOS R, the heavy front weight allowed the bottom part of the camera to swing back into my palm. To compensate for this, I had to take up the extra weight with my left hand, which I usually use for focusing (I still manual focus a lot of images). If you add to this the Control Ring at the front of the RF lenses, I was trying to support the weight of the camera, focus, zoom, and adjust ISO with my non-primary hand.
The image above was some with the Canon EOS R, RF 28-70 f/2L, and no grip. It was taken over multiple days and was during a period of learning how balance in the mirrorless world worked.
After a couple of weeks of testing the EOS R platform with Canon, I called and discussed a bit of what I was experiencing. The company immediately sent out a Canon EOS 1DX Mark III with some lenses for me to figure out if the muscle memory problems I was battling were because of my gravitation towards built-in vertical grips.
Sure enough, it was like I was using a camera that locked onto a target whenever I held it to my eye. What was funny was that I had grown fond of the approach of shooting mirrorless, and so I picked up an LCD viewfinder adapter and started shooting with the camera as if it were a mirrorless body with a built-in vertical grip. The image below was created with the EOS 1DX Mark III and a 35mm f/1.4L II.
This brings us to a bit of a conundrum when it comes to gear selection. Obviously, the idea of how one sets up their system is completely subjective. Even between specific photoshoots, this approach might change for a photographer.
However, the way to go about addressing this issue can be done in two ways: Lighter lenses, or heavier or larger camera bodies.
With my first request to Canon after being named an Explorer or Light, I asked them if I could try the EOS R6 with a RF 24-70 f/2.8 L lens in an effort to see if I drew the camera to my eye like I would with a gripped camera like the Canon EOS R3. In many ways it was a nice reduction of weight versus the RF 28-70 f/2 L, but still had a slight issue of pressing the bottom of the camera body into my palm. While it wasn’t anywhere near what I eventually referred to as the “crab fingers” issue that I had with another platform, it was still something that my personal preference gravitated again towards a vertical grip for support. In one of the only outings I had with this combo due to being under the weather, I shot one train (the image below) and called it a day.
For me, the solution was a vertically gripped Canon EOS R5 (and maybe another body with a built-in grip in the future). While the lenses and their weight matter, the torquing of the camera chassis forward at the top, therefore loading my left hand was the determining factor towards modern mirrorless camera weight distribution.
Something I encourage every photographer to try is taking a couple of lenses on their camera and walking around, paying close attention to how the feel and hold dynamics change from lens to lens. If you want to get a rough idea of how a grip might impact your holding of a camera, attach a tripod head alone to the camera and see if it levels of the lens when you bring it to your eye. With a little experimenting, you may find that the camera’s balance becomes an afterthought that allows you to focus (no pun intended) more on creating.

If there’s one annoying aspect of cameras, particularly mirrorless cameras that are constantly powering an LCD or EVF the whole time they’re turned on, it’s battery life. There are grips you can get for some cameras to let you take advantage of multiple batteries or you can go with external power, but not all cameras. […]
Engineer Builds a DIY Hot-Swappable Battery Grip for His Canon EOS M
An electronics engineer has created a do-it-yourself hot-swappable battery solution for photographers who want to keep their cameras going through shoots without stopping or losing any footage.
Needing to hastily swap a battery during a shoot so as not to miss anything is likely a familiar scenario to most, if not all, photographers and videographers. Sometimes, that swap needs to be timed perfectly at the risk of missing an important shot, especially if a photographer is tasked with documenting moments that cannot be repeated, like weddings, sports, events, or really any live coverage. However, camera batteries die: it is inevitable, and it is an inconvenience that can disrupt the flow of any shoot.
In an attempt to remedy this problem, U.K.-based electronics engineer and self-described embedded software artist, Olly Funkster, has successfully created a DIY response to this issue, which was first shared by Hackaday. The hack is based around a 18650 lithium-ion battery, which, as explained by Battery Junction, is often used in high-drain devices, such as laptops, due to its superior capacity and discharge rates. It is slightly larger than the familiar AA battery.
Funkster created a fully customized battery grip for his Canon EOS M, not just to deal with the battery run-time issue but also because when in use on a tripod, the battery cannot be replaced unless the camera is taken off the tripod to access the slot -- another situation that is likely painfully familiar to photographers.
The project began with a 3D-printed battery grip with a boost converter and two slots that fit one 18650 battery each. This means that the camera is constantly powered using one of the inserted batteries, while the other is kept in reserve. The cells are monitored by an STM32 microcontroller, which, as explained by an electronics engineer Sanskar Biswal , is applied to many areas in electronics, from printers to complex circuit boards in vehicles.
The STM32 microcontroller enables a seamless switch between the batteries if one has been fully drained or is removed, meaning the camera remains turned on and the capture of footage is not interrupted. Funkster's battery grip even has an OLED display which shows which slot has a battery inserted and how much charge is left in each.
While not a recommended action for those who are not confident in their DIY skills, Funkster used a drill to allow the battery grip -- which is tightly wrapped around the camera -- to connect directly "via pin headers that pass through a hole drilled in the camera’s case." This is a permanent modification to the camera, but it allows Funkster to easily access the SD card slot without having to remove the DIY battery grip.
Funkster has shared his 3D pattern, however, because this grip requires custom electronics installed, it is primarily meant to serve as a reference for anyone who wants to attempt creating something similar for their own camera.

A Hot-Swappable Battery Grip Keeps The Camera Rolling
There's nothing worse than being in the middle of an important shot, only to have the camera's batteries die on you. The losses can be very real, so it's best to avoid them entirely. In an effort to do so, [funkster] built himself a battery grip for his Canon EOS M.
The hack is based around the venerable 18650 battery, packing 3.6V of lithium-ion goodness into a compact metal can. [funkster]'s build has slots for two of these cells, powering the camera off of one and keeping the other in reserve. The cells are monitored by a STM32 microcontroller, which switches from one battery to another as they run out or are removed. This allows batteries to be swapped while the camera is on - a highly useful feature. There's even an OLED display to keep an eye on the state of charge of each cell.
The manner in which power is connected to the camera is rather amusing. An original Canon battery that slides inside the camera was gutted and turned into a simple adapter for the battery port. The battery grip, which wraps around the camera body, connects to this via pin headers that pass through a hole drilled in the camera's case. It's a permanent mod, but one [funkster] is happy with for the added usability - especially as doing it this way still provides easy access to the SD card slot.
Keeping a camera juiced on the go can be a headache without the right gear. [funkster] demonstrates that if you can't buy it, you can always build it yourself. If your problem isn't battery power, but your camera is overheating, you can of course fix that too. Video after the break.
