Full Frame GAS Attack: Should I Pull the Trigger on the Lumix S5 ?

Am I Going to Buy a New Full Frame Camera?

No… well, I’m not completely sure. There’s a reason for my hesitation, or perhaps it’s just GAS (Gear Acquisition Syndrome).

First off, I already own a full-frame camera, the Canon 5D Mark II. I originally bought it to experiment with and test vintage manual lenses. If there’s one thing that makes full-frame cameras worth considering—at least for myself—it’s exactly this: using and testing vintage Pentax, Olympus, Minolta or other classic lenses on a full-frame sensor, where they were originally intended to shine. These lenses perform much better on full frame than on a crop sensor, showing their true angle of view and giving a more authentic look.

However, my experience with the Canon 5D Mark II has been disappointing. It’s an old-school DSLR without modern features like focus peaking or magnification, both of which are crucial for manual focusing. To this day, I don’t understand why digital DSLRs don’t have split-image focusing screens, which were common in older cameras. Manual photography is still highly valued by many users, and features like these would make it much easier. In the past, I had focus confirmation on my Pentax, but it’s just not the same. So, it’s clear: the Canon 5D Mark II has to go.

Full Frame: Is It Worth It?

The primary reason I would get a new full-frame camera would still be for vintage lenses. But the question is, do I really need full frame? I already own several Micro Four Thirds (MFT) cameras, which are my main system, and more recently, I picked up a Leica T Type 701, which has a larger sensor than my MFT cameras. Is it really necessary to go all the way to full-frame when I’m already happy with what I have?

For my main photography interests—wildlife and bird photography—MFT is unbeatable. The system’s crop factor and extensive range of long lenses make it ideal for getting those distant, detailed shots of birds and wildlife. The lightweight setup also makes it easy to carry around for long hikes or extended periods outdoors. Full frame simply can’t compete with MFT in this area.

Another consideration is that working with too many different systems can become impractical. You lose the muscle memory and deep familiarity with each camera when constantly switching between systems.

Enter the Lumix S5

Despite my reservations about full-frame, there’s one camera that’s really caught my eye: the Panasonic Lumix S5. It’s a compact full-frame option, offering excellent features for both photography and videography, and it’s currently available at a significantly reduced price because it’s being replaced by the Lumix S5 II. At the moment, you can find the Lumix S5 for around €949 in Europe or £799-£850 in the UK, which is a fantastic deal for what it offers. Even in the US, prices are hovering around $1000, making it one of the most affordable full-frame options on the market right now.

I haven’t personally tested the Lumix S5, but from what I’ve seen in reviews and videos, it checks all the boxes for anyone looking for a high-quality full-frame camera. The 24.2MP full-frame sensor, dual native ISO, and 4K 60p video recording are all top-tier features at this price point. Plus, there was a recent firmware update in October 2024, keeping the camera fresh and up to date.

One of the key selling points for me is the L mount, which the Lumix S5 shares with my Leica T. This opens up a wide range of lens options, giving me more flexibility with my gear. It’s also a hybrid camera, ideal for someone like me who occasionally dabbles in videography. Features like 10-bit internal recording and dual native ISO make it a powerful tool for both photos and video, especially when paired with vintage lenses for unique creative looks.

Do I Really Need It?

That brings me back to my original question: do I really need another full-frame camera? While the Lumix S5 is incredibly tempting, I’m not sure it would ever replace my MFT system, which remains my go-to setup for wildlife photography. Full frame can’t compete with the portability and reach that MFT offers when I’m out in the field shooting birds or animals.

Still, the Lumix S5 could be a perfect complement to my existing gear rather than a replacement. It would serve a different purpose—mainly for testing vintage lenses and perhaps for the occasional portrait or landscape shoot where full-frame depth of field and dynamic range can really shine.

Conclusion

So, will I buy a new full-frame camera? I’m still undecided. But I know that if I do, the Panasonic Lumix S5 is a strong contender, especially at its current price. For less than €1000, you get a compact, full-frame camera with an excellent sensor, versatile lens mount, and modern video features. It’s a fantastic option for anyone looking to enter the full-frame world without breaking the bank.

For me, however, Micro Four Thirds will remain my main system—nothing beats it for wildlife photography. The Lumix S5 would be a luxury, not a necessity, but it’s definitely one I’m seriously considering.

  1. You need it… Buy it!!! 🤣🤣🤣

    Seriously though, even if you have a 300mm lens and crop, your bird and animal photographs will have so much more detail and be so much better than you have now. And you’ll never have to worry about noise in images again!

    1. Haha, I saw that coming! 🙂

      But Mark, you know that image quality depends more on the lens than the camera itself. A lens that outperforms my compact Leica 100-400mm would likely be heavy and probably expensive. That’s why I don’t think I’ll be leaving my Micro 4/3 system anytime soon.

      You do make a good point though—more detail and less noise are appealing. However, it will take more than that to convince me this time!

      1. I seen a huge jump in quality from my M43 and APSC cameras and lenses to the Nikon Z series. A HUGE jump. There’s so much more benefit (as you know). Even the cheapest S5 lenses will outperform the M43 lenses with the combination of sensor and modern design. Plus of course, just that clarity that modern full frame brings you.

        Buy it… That’s an order! 🤣

      2. Yep, I expected a reply from you about this 🙂

        You know, after the whole Pentax situation, and then all the hassle with Fujifilm—selling off the cameras and lenses—it took a while for everything to be gone. There are options, of course. You can take your gear to local camera stores, but they don’t offer much, even if the equipment is practically new. And then there’s MPB, but I don’t even want to start with that.

        I’ve invested so deeply into the Micro Four Thirds (m4/3) system that I have no intention of giving it up. I’m genuinely happy with it. I really mean that.

        If I ever make the switch, it would be as an additional system, mainly for landscape and architectural photography. I already have lenses for it, which is why it’s so tempting.

      3. Indeed, nothing wrong with having two systems.

        On that note… Today’s blog which I’ll put up later, I have bought a few “new” photography things to share, which I think you’ll be impressed with (including a vintage lens and new camera!)

  2. I ditched my full frame setup a couple of years ago, and switched to m43. The reason being that I can now fit two Olympus bodies and four Pro series lenses, plus filters, a drone and sandwiches in my bag. I couldn’t do that with full frame and I can still get razor sharp prints at 16″ x 20″ with little grain. In fact I can’t really tell the difference between full frame and m43. I am 70 and still a working photographer – I would have retired two years ago if I used full frame as they are just too heavy to lug around.

    1. Hello James!

      First of all, thank you so much for your response! It’s great to hear positive opinions about the Micro Four Thirds (m4/3) system, and I suspect you’re not the only one who feels this way.

      When I first switched from Fujifilm to Olympus, I must admit, I was a bit concerned about the image quality. However, those fears quickly turned out to be unfounded. One of the major advantages of the m4/3 system is its compactness, not to mention the significant difference in weight, which is a big plus.

      I have no intention of abandoning the m4/3 system—quite the opposite. For me, considering the Lumix S5 as an extra system would only be about using my old lenses (Pentax, OM Zuiko, etc.) on a sensor format they were originally designed for. And since the Lumix S5 is now being offered at such an affordable price, I wouldn’t have to put in much extra if I sold my old Canon 5D MKII and its lenses.

      In any case, thank you again for your thoughtful response!
      Marc.

  3. I guess one thought would be, what genre of photography would you use it for. I’m sure you already know (but in case you do not) it just has contrast detection focus which again depending on your use would be inconsequential. Just my 2 cents and it is probably only worth 1 cent.

    1. Hello Guy,
      Everyone has different needs when it comes to choosing a camera. But when you’re approaching 65, come from the analog era, and used to develop film yourself, your requirements may be a bit different.
      For example, in my bird and wildlife photography, the autofocus system is crucial. However, for landscapes, architecture, and any situation where you have time to compose your shot, contrast detection autofocus works just fine. And if needed, you can always switch to manual focus.
      This is often the case when you choose an older camera model. Sure, newer models may offer better performance, but can you get significant improvements at a reasonable price?
      I really appreciate your feedback; it keeps me motivated. So, thank you, and hopefully, we’ll talk again soon!
      Best regards,
      Marc

      1. Well being a 66 year old fart I can appreciate your desire for lighter equipment. I have an OM-1 MK II as well as a Pen-F. Everything has a compromise to it, you just have to figure which ones you are ok with. I’m quite happy with M43 and have no intention of dumping it even if OMS and Panny decided to quit the format.

      2. That is very good advice, Guy, and I completely agree with you. I have no intention of leaving the Micro Four Thirds system. It’s also encouraging to hear that many photographers remain loyal to the system. It only reaffirms that we made the right choice, even though there are others who criticize it.
        Best regards,

  4. Looks interesting.

    I am a bit older than you so my concern would be the size and weight of equivalent lenses for full frame. But it is worth consideration. Might also be worth a look at the latest and greatest from other companies. Fujifilm are making great strides with their x-trans processors and Sony appear to be shrinking the size of cameras as well.

    Having said that I am really wedded to the MFT format. It is much more compact than my APS-C camera and lens.

    1. Hey Bearfuzzy,

      The weight difference between the Lumix S5 and the new OM-1 MKII is just a little over 100 grams, so that won’t be a game-changer. However, the Micro Four Thirds (M4/3) system does have a 2x crop factor, which has a significant impact on lenses. Lenses for M4/3 become much more compact when compared to full-frame lenses with the same effective focal length. So yes, you will definitely feel a difference in terms of size and handling when using lenses on an M4/3 versus a full-frame system.

      That said, I would primarily use the S5 for shooting with vintage lenses. In that case, the weight difference doesn’t really matter—it’s just about those 100 extra grams on the camera body itself. For me, it’s the ability to use those older lenses that makes full-frame appealing.

      Like you, I would never trade in my Micro Four Thirds system for a full-frame setup. My decision to get the S5 was simply because I found it at a great price and could use it specifically with my vintage lenses. Because, let’s be honest, if you’re going to shoot with an old vintage OM Zuiko 28mm lens, you’re either going to do that on a full-frame digital or an old film camera, not on a Micro Four Thirds.

      As for other brands, I’ve had Fujifilm cameras but I sold them. And Sony, wel, great sensor but the build quality just doesn’t compare to a Lumix.

      Eventually, if I sell my Canon 5D MKII with lenses, I’ll probably need to add around €300 to €400 for the S5.
      And then the question arises—should I keep the money or invest in a full-frame S5 as an extra camera system ?
      Thanks for your input, Bearfuzzy, and I hope to see you back here.
      All the best!
      Marc.

      1. The Lumix sounds like the one to go with then.

        I think I already know what you will do.

        Be interesting to see how you go with your new camera.

      2. Well, you might be mistaken about that, normally, I don’t hesitate to go for it, but this time it’s different. It’s a tough decision, mainly because I know I probably wouldn’t use it often. In that case, it feels like a waste of money.

    1. Thanks for the comment! I just visited your website and was actually trying to find out what type of camera you use yourself—maybe a Lumix or Leica?—but I couldn’t find it.

      A full-frame camera that uses the same lenses as my Leica T would indeed be convenient. My issue is mainly that I already use two systems, and that makes me doubt whether three are manageable.

      We’re still figuring things out. But every idea and comment helps me move forward a bit—yours included.

      So thank you, and be sure to visit again; you’re always welcome!

      1. I use a Nikon Z 8 and a Nikon Z 6 ii. The auto focus isn’t as fast or intelligent as Canon, but the Nikkor lenses hold the edge. Sony has the largest family of mirrorless lenses, but users complain about the interface and machined like feel of the sharp edges and square corners. The Leica and Lumix system was my second choice. I went with Nikon because of my family’s long history with the brand, going back to the F4. The mirrorless is still a work in progress but it’s improving. Shooting in RAW helps in post. I just correct for user or camera errors. My photos don’t usually have a cinematic preset overlay.

        I look forward to your next advancement. I trust that it will be the right choice, and a natural leap for you! 😊

      2. Thank you for sharing insights into your camera gear. It’s always fascinating to see the equipment photographers use – especially in relation to their photos. But what’s even more interesting is understanding why they make those particular choices. Your explanations were clear and made perfect sense.

        Thanks again for sharing your thoughts.
        Wishing you all the best,
