Sony RX10IV : A Love Letter

There's a camera in my bag that I didn't expect to love. I also didn't expect to occasionally want to throw it into the Seine River or an Amsterdam canal. But here we are.

After years of carrying it on layovers across the world, I believe the Sony RX10 IV deserves a proper retrospective. Not a spec or pixel peeping breakdown, that's not my jam and has been done to death anyway. This is more of an honest reckoning with a camera that has surprised me, frustrated me, and produced some of my favorite images in equal measure.

Taking a break in Paris with the Sony RX10IV

The Snob Problem
I'll be upfront, I sort of needed to get over myself before I could really appreciate this camera.

As someone who has long used pro level cameras as my main kit, the idea of carrying a bridge camera felt like a step backward. Bridge cameras carry a certain reputation, fairly or not, as the domain of beginners or cruise ship tourists maxed out at full zoom on a dolphin. My inner street photography snob and Fujifilm fanboy had opinions.

As it turns out, those opinions were wrong.

What It Actually Is
Sony, Nikon, and Panasonic have all produced bridge cameras over the years. The category is defined by a lens that's fixed in place with an extended zoom range. For instance, the Nikon P1100 stretches to a dizzying 3000mm focal length on the extreme end. A bit crazy, but shows what these cameras can cover. The RX10 IV covers 24 to 600mm optically (1200mm digital) and is paired with a Zeiss f/2.4 to 4.0 lens and a 1 inch sensor. On paper that's a compelling combination. In practice it's genuinely impressive.

The Cameras Before It
The RX10 IV certainly didn't arrive in a vacuum. Over the years I've cycled through a handful of compact travel cameras in search of something that could complement or occasionally replace my main kit: the Sigma DP1x with its remarkable Foveon sensor, the Nikon P7000, the Fujifilm X100T (still a go to), and the Panasonic LX10. Each had something going for it. None quite hit the mark as a genuine everyday carry for the kind of shooting I typically do on layovers.

The RX10 certainly isn't pocketable, which immediately disqualifies it from one version of the travel camera dream. But its form factor is reasonable when the camera is off, and what it gives you in return for that size is substantial.

Real World: One Lens to Rule Them All
The single biggest practical advantage of the RX10 IV is also the most obvious one, you leave the house with one camera and one lens and you're genuinely covered. No swapping glass on a cobblestone street in the rain. No deciding between the wide angle and the telephoto for a day that might go either way. No missed moment because the right lens was in the bag instead of on the body. For a pilot on a layover in a city I may not return to for months, that simplicity matters. I'm not setting up a studio. Rather, I'm on the move and the RX10 keeps up without demanding much in return.

The reach at the long end is genuinely impressive and occasionally outright fun. Street scenes compressed from a distance, cats lounging on balconies, a moment happening across a plaza that you'd never get to in time on foot. The 600mm end certainly is not optically perfect and I'll get to that, but it opens up creative possibilities that simply don't exist with a prime or a standard zoom.

Battery life is typically a pleasant non issue. I rarely find myself rationing shots on a full day out, which is not something I can say about every camera I've owned. Though I do keep a spare battery with me at all times and have occasionally needed it, mainly when I have failed to top off charge.

Image Quality
In good light the RX10 produces images that have genuinely impressed me. In fact some of those images are my favorite from any camera I've used. The 1 inch sensor and Zeiss glass are a solid combination and at sensible focal lengths in decent conditions the results are sharp, nicely rendered, and truly satisfying to look at.

The caveats are real though. Low light is where the relationship goes south. I've missed shots that mattered because the RX10 simply couldn't hold it together. When you're somewhere maybe once and the light is doing something interesting in a dark alley or rainy street and the camera is fighting you, it stings. It's not a camera I'd choose for that kind of shooting if I had options. That's the price of the 1 inch sensor and the zoom range, and it's worth knowing before you commit.

At about 400mm and beyond, the image quality drops noticeably. It's usable but you're asking a lot of the optics at that extreme, and the results reflect it. Think of the long end as a creative tool rather than a precision instrument and you'll be fine. There are gimmicks onboard such as Clear Image Zoom (digital) which goes beyond the 600mm mark, but if I need that much zoom it isn't a worthwhile shot to me.

The RX10 IV also lacks image stabilization, so one does need to shoot with a steady hand in low light or keep a tripod handy. I carry a small Manfrotto travel tripod that's come in handy many times and especially for use with my 10 stop Urth ND filter that's always on hand as well. Long exposures are one of my favorite styles to work with so a necessity to have a steady base.

Build Quality
For a camera that is not technically weather sealed, it has held up to years of genuine abuse. I don't let rain or snow keep me indoors and I've pushed the RX10 through some serious weather slogs. Along with the inevitable drops and knocks of life on the road, it has remained functional and solid. I also keep it on a Peak Design Cuff which has saved it from worse fates on more than one occasion.

The Loathing
I said love letter, and I meant it, but honesty requires acknowledging the rough edges.

As mentioned above, low light performance is the most consequential flaw in real world use. When a moment is happening in bad light, the RX10 IV will sometimes just fail to capture it in any meaningful way, and there's nothing to be done about it. That's a sensor size limitation more than anything else, but it surfaces at the worst times and no amount of cranking up the ISO will save the shot.

Startup time can also be annoying. If the camera is off and something happens in front of you, you will perhaps miss it. You learn to keep it on in situations where things are dynamic, which helps, but it shouldn't be necessary. The other day I was waiting for a cyclist to come by a scene in Amsterdam and I just kept tapping the shutter button to keep it from turning off so I didn't miss the shot. Sure, you're burning battery but a worthy trick to not miss the shot.

The lockups are the most maddening issue. Occasionally and with no obvious pattern, the camera simply freezes mid session. A restart fixes it but the moment is gone. It hasn't happened often enough to be a dealbreaker but it has happened enough to remember. Occasionally you'll need to pop the battery out and reinsert it to reset the camera but thankfully that's rare.

An RX10 VI Wish List
RX10 what you say? My original draft of this post assumed the RX10 line was dead along with much of the industry, as it had been nearly a decade since the IV was launched. So naturally right before I'm ready to publish, Sony finally announced the long awaited RX10V! You could imagine my surprise and excitement, but alas, it isn't the case. The new successor seems like a wasted opportunity.

The new RX10V comes with the exact same lens (not the worst thing) and sensor, and the rear screen still only tilts rather than fully articulating. The EVF did get a real bump though, bigger and sharper, borrowed from the A7 V line, so credit where it's due. Beyond that it's mostly a body redesign and a processor bump wrapped around the same core imaging hardware from 2017. The enhanced video options and AI additions do nothing for me.

That's a shame, because a more capable successor would have been pretty amazing. If anyone at Sony is reading, squeezing in a larger APS-C sensor would be transformative for this concept along with a slightly wider and brighter lens. I'd certainly trade a slight reduction in focal length for image quality. A modernized processor, yes, but please spare us the overbearing AI processing gimmicks. Sony did actually add dust and moisture resistant construction this time around, so that one's checked off. Give me a fully articulating screen, another customizable button, and closer focus capability and I'll give you my money all day long.

Sadly, I'll be skipping the "upgrade" to the V and maybe in another 10 years I'll buy the RX10 VI. Maybe.

Where It Sits Now
Since switching from a messenger bag to a backpack on my work trips, I've been bringing my Fujifilm X Series kit more often and the RX10 has been staying home a bit more than it used to. But I'm not abandoning it. There are trips and occasions where one capable camera and no lens decisions is exactly the right answer, and for those days the RX10 IV remains the best option I've found.

It won't do everything, but it does most things well enough and that's usually enough for me. For a bridge camera from 2017, that's a legacy worth celebrating.
