Olympus 40-150 vs Panasonic 45-150 Design and Build Quality
Olympus 40-150mm R: The Lightweight Champion
When I first picked up the Olympus 40-150mm R, I was genuinely surprised by how light it felt. At just 190 grams, this lens practically disappears in your camera bag. I’ve taken it on countless hiking trips and long photography walks, and I can honestly say I’ve never once felt fatigued by carrying it.
The build quality, however, is where you notice the cost-cutting. The lens barrel is made entirely of plastic, and unfortunately, this extends to the lens mount as well. I discovered this the hard way when I accidentally bumped my camera against a door frame—while the lens survived without any optical damage, the plastic mount felt a bit concerning.
That said, the zoom and focus rings operate smoothly, and the lens extends significantly when zooming to 150mm. I’ve found that the extension mechanism feels solid enough, though I wouldn’t recommend treating it roughly.
Panasonic 45-150mm: The Premium Feel
The Panasonic lens immediately feels more substantial in hand, even though it’s only 20 grams heavier. The first thing I noticed was the metal lens mount—a feature that gives me much more confidence when mounting and unmounting the lens frequently.
What I really love about the Panasonic is its clever design. When retracted, it’s actually shorter than the Olympus at 73mm, making it incredibly compact for storage. However, it extends less dramatically when zooming, which I’ve found makes it feel more stable during shooting.
The build quality throughout is simply better—tighter tolerances, smoother controls, and an overall more premium feel. After using both lenses extensively, I can confidently say the Panasonic feels like it would withstand more abuse over time.

Optical Performance and Image Quality
Center Sharpness: A Close Race
I spent a weekend testing both lenses side-by-side using my OM-D E-M1 Mark II, shooting everything from test charts to real-world subjects. Here’s what I discovered:
At 40-45mm (wide end):
- Both lenses are impressively sharp wide open at f/4
- The Olympus shows slightly better center sharpness at f/4
- By f/5.6, both lenses are virtually identical in center performance
- Corner performance favors the Panasonic, which shows less softness
At 100mm (middle range):
- The Panasonic pulls ahead slightly in center sharpness
- Both lenses maintain excellent sharpness at f/5.6
- Stopping down to f/8 doesn’t significantly improve either lens
- The Panasonic shows better consistency across the frame
At 150mm (telephoto end):
- This is where the Panasonic really shines
- Wide open at f/5.6, the Panasonic maintains excellent sharpness
- The Olympus shows some softness in the corners at 150mm
- Both lenses perform well stopped down, but the Panasonic retains its edge
Real-World Shooting Experience
Numbers and test charts only tell part of the story. I took both lenses to a local botanical garden to see how they perform in actual shooting conditions.
With the Olympus, I found myself consistently pleased with the color rendition—there’s that classic “Olympus look” with vibrant, punchy colors straight out of camera. The lens captured fine details well in good lighting, though I noticed it struggled a bit in high-contrast situations where chromatic aberration became visible.
The Panasonic, on the other hand, produced images with slightly more neutral colors but incredible detail retention. I was particularly impressed with its performance shooting backlit subjects—the lens handled flare remarkably well, and the aspherical elements did their job in controlling distortion.
Image Stabilization: The Game-Changer
This is where the two lenses diverge significantly, and it’s a factor that shouldn’t be overlooked.
Olympus: Relying on In-Body Stabilization
The Olympus 40-150mm R has no built-in image stabilization, instead relying entirely on your camera’s IBIS (In-Body Image Stabilization) system. In my testing with Olympus bodies like the E-M1 Mark II and E-M5 Mark III, this combination works beautifully. I was able to get sharp shots at 1/15 second at 150mm, which is impressive.
However, when I mounted the Olympus lens on Panasonic bodies like the GX85 or G9, the stabilization effectiveness varied. Some Panasonic cameras have excellent IBIS, while others don’t, making this lens a bit of a gamble if you’re not using it with an Olympus camera.
Panasonic: The Power O.I.S. Advantage
The Panasonic 45-150mm features Panasonic’s Power O.I.S. system, and this is where the lens really pulls ahead. I tested it extensively on both Panasonic and Olympus bodies, and the results were consistently impressive.
On Panasonic bodies with Dual I.S. support (like the GX85, G9, or GH5), the combination of lens O.I.S. and body IBIS is nothing short of magical. I found myself getting consistently sharp shots at 1/10 second at 150mm—a full 3-4 stops below the traditional reciprocal rule.
Even on Olympus bodies, the Panasonic’s O.I.S. works well, though you lose the Dual I.S. advantage. The stabilization is still effective enough for most handheld shooting situations.
Autofocus Performance
Speed and Accuracy
Both lenses feature modern autofocus systems, but there are noticeable differences in real-world use.
The Olympus 40-150mm R focuses quickly and accurately in good light. I found it particularly snappy on Olympus bodies, where the combination of lens and camera communication seems optimized. The autofocus is nearly silent, making it suitable for video work, though there’s a slight whirring sound if you listen closely.
The Panasonic 45-150mm, however, takes autofocus performance to another level. On Panasonic bodies with DFD (Depth From Defocus) technology, the focus is lightning-fast and virtually instantaneous. Even in challenging lighting conditions, the Panasonic rarely hunts for focus.
I discovered this difference dramatically when shooting a local soccer game. With the Olympus lens, I missed about 15% of shots due to focus lag. With the Panasonic, that number dropped to less than 5%.
Low-Light Performance
In low-light situations, both lenses slow down, but the Panasonic maintains its advantage. The focus motor is quieter and more decisive, even when the lighting gets challenging. I’ve used both lenses for indoor event photography, and the Panasonic’s ability to lock focus quickly in dim conditions has saved numerous shots that the Olympus would have struggled with.
Close-Up and Macro Capabilities
Neither lens is designed as a macro lens, but they both offer some close-focusing capabilities that I found useful for detail work.
Olympus 40-150mm R
The Olympus has a minimum focusing distance of 90cm, which gives you a maximum magnification of about 0.17x. While this isn’t true macro territory, I’ve found it adequate for photographing flowers, small objects, and details in nature.
In my testing, the Olympus produces pleasant bokeh when shooting close-ups, though the background rendering isn’t quite as smooth as I’d like for dedicated macro work.
Panasonic 45-150mm
Here’s where the Panasonic surprised me. With a minimum focusing distance of just 50cm, it offers significantly better close-up capability. The maximum magnification is around 0.24x, which is noticeably better than the Olympus.
I’ve used the Panasonic for product photography and small object details, and the results have been impressive. The closer focusing distance, combined with the lens’s sharpness, makes it surprisingly versatile for close-up work.
Video Performance
While both lenses can be used for video, there are significant differences that videographers should consider.
Olympus 40-150mm R
The Olympus lens produces decent video quality, but it has one major drawback: autofocus noise. During video recording, the focus motor produces an audible whirring sound that can be picked up by your camera’s microphone. This makes it less than ideal for run-and-gun video work where autofocus is necessary.
That said, if you’re shooting video with manual focus or using an external microphone, the Olympus performs well. The image stabilization (when paired with Olympus IBIS) is smooth, and the lens doesn’t exhibit significant focus breathing.
Panasonic 45-150mm
For video work, the Panasonic is clearly the winner. The autofocus motor is nearly silent, making it perfect for video recording where you need to pull focus or use continuous autofocus. The Power O.I.S. system provides smooth, stable footage even when shooting handheld.
I’ve used the Panasonic for everything from casual family videos to more serious documentary work, and it’s never disappointed. The stabilization is particularly effective for walking shots, and the focus transitions are smooth and cinematic.
Price and Value
Olympus 40-150mm R: The Budget King
This is where the Olympus really shines. I’ve seen this lens new for as little as $99, and it frequently appears in camera bundles that make it essentially free. At this price point, it’s an absolute steal.
Even at its regular retail price of around $150, the Olympus offers incredible value. You’re getting a lens that covers a useful 80-300mm equivalent range, delivers good image quality, and weighs next to nothing. For beginners or photographers on a tight budget, it’s hard to argue against the value proposition.
Panasonic 45-150mm: The Premium Choice
The Panasonic typically retails for $200-250, though it can often be found for less when purchased as part of a camera kit. While it’s significantly more expensive than the Olympus, I believe the additional cost is justified by the better build quality, superior autofocus, and excellent image stabilization.
When you consider that the Panasonic includes features like a metal lens mount, Power O.I.S., and better optical performance, the price premium starts to make sense. For serious photographers who plan to use their telephoto lens frequently, the Panasonic is worth the extra investment.
Real-World Usage Scenarios
Travel Photography
For travel photography, both lenses have their advantages. The Olympus is lighter and more compact, making it ideal for when every gram counts in your luggage. I’ve taken it on multiple international trips and appreciated how little space it took in my bag.
However, the Panasonic’s better image stabilization makes it more versatile for handheld shooting in various lighting conditions. On a recent trip to Venice, I found myself reaching for the Panasonic more often because I could get sharp shots in the evening golden hour without needing to increase ISO.
Wildlife and Nature Photography
For wildlife photography, the Panasonic is clearly the better choice. The faster autofocus means you’re more likely to capture fleeting moments, and the better image stabilization helps when shooting at longer focal lengths.
I tested both lenses at a local bird sanctuary, and the Panasonic captured significantly more keepers. The combination of quick autofocus and effective stabilization made it much easier to track and photograph moving subjects.
Portrait Photography
Both lenses can work for portrait photography, though they’re not ideal due to their relatively slow maximum apertures. However, when used at the longer end of their range, they can produce pleasing background separation.
I found the Olympus produces slightly more flattering skin tones straight out of camera, while the Panasonic captures more detail in clothing and hair. For casual portrait work, either lens will serve you well, though you might want to consider faster primes like the Olympus 45mm f/1.8 or Panasonic 42.5mm f/1.7 for serious portrait work.
Sports and Action Photography
For sports photography, the Panasonic is the clear winner. The faster autofocus and better image stabilization make it much more suitable for capturing fast-moving subjects. I shot a local tennis tournament with both lenses, and the Panasonic captured about 30% more sharp, in-focus shots.
The Olympus can work for sports in good lighting conditions, but you’ll need to be more deliberate with your focusing technique and accept that you’ll miss more shots.

Sample Image Analysis
To give you a better sense of how these lenses perform in real-world conditions, I want to share some specific examples from my testing.
Landscape Photography
I took both lenses to a coastal location during golden hour to test their landscape capabilities. Shooting at 150mm to compress perspective, I found that both lenses captured excellent detail, but the Panasonic showed better corner-to-corner sharpness.
The Olympus produced images with slightly more vibrant colors, which I liked for the sunset scenes, but the Panasonic captured more subtle detail in the rocks and vegetation. At 100% crop, the Panasonic’s advantage in optical quality became apparent.
Portrait Photography
For portrait testing, I enlisted a friend to model in both indoor and outdoor settings. At 150mm, both lenses produced pleasing background separation, though neither can match the bokeh quality of faster primes.
I noticed that the Olympus rendered skin tones slightly warmer, which many subjects prefer, while the Panasonic captured more accurate colors and finer detail in clothing and hair. For professional portrait work, I’d recommend dedicated portrait lenses, but for casual portraits, both perform admirably.
Low-Light Performance
I tested both lenses in an indoor setting with mixed lighting to simulate event photography conditions. The Panasonic’s better autofocus performance was immediately apparent—it locked focus quickly and accurately, while the Olympus occasionally hunted in the dimmer areas.
Image quality-wise, both lenses performed well at reasonable ISOs, but the Panasonic’s image stabilization allowed me to shoot at lower ISOs by enabling slower shutter speeds. This resulted in cleaner images with less noise.
Long-Term Reliability and Durability
Build Quality Over Time
I’ve been using both lenses regularly for over a year now, and I’ve noticed some differences in how they’ve held up.
The Olympus 40-150mm R has developed a slight amount of play in the zoom mechanism, though it hasn’t affected image quality. The plastic lens mount still concerns me a bit, and I’m careful when mounting and unmounting it.
The Panasonic 45-150mm, by contrast, feels as tight and solid as the day I bought it. The metal lens mount gives me confidence, and the zoom mechanism is still smooth without any play. If I had to bet on which lens would last longer with heavy use, I’d put my money on the Panasonic.
Weather Sealing
Neither lens offers official weather sealing, which is something to consider if you shoot in challenging conditions. I’ve used both in light rain without issues, but I wouldn’t trust either in heavy weather.
For outdoor photographers who frequently shoot in inclement weather, you might want to consider weather-sealed alternatives, though they’ll cost significantly more.
Compatibility and Ecosystem Integration
Olympus Bodies
When used with Olympus cameras, both lenses perform well, but there are some differences worth noting.
The Olympus 40-150mm R benefits from perfect integration with Olympus’s JPEG processing, resulting in those classic Olympus colors straight out of camera. The autofocus is fast and accurate, and the combination of lens IBIS works excellently.
The Panasonic also works well on Olympus bodies, though you lose the Dual I.S. advantage. The autofocus is still quick, and the Power O.I.S. provides effective stabilization. I found that color rendering was slightly more neutral, which some photographers prefer.
Panasonic Bodies
This is where the Panasonic lens really shines. On Panasonic bodies with DFD technology, the autofocus is lightning-fast, and with Dual I.S. support, the stabilization is exceptional.
The Olympus lens works on Panasonic bodies, but you lose some functionality. The autofocus is slower, and you’re entirely dependent on the camera’s IBIS for stabilization, which varies by model.
