Overview of the OM SYSTEM Olympus OM-3 and Sony Alpha 6700
The OM SYSTEM Olympus OM-3 is priced at $1,699.99, while the Sony Alpha 6700 is more budget-friendly at $1,498.00, making it about 17% cheaper. Both cameras are designed to cater to photographers seeking high-quality results, but they target slightly different audiences and use cases. The OM-3 focuses on weather-sealed durability and creative features ideal for adventurous photography, whereas the Alpha 6700 leverages advanced AI technology for superior image quality and subject tracking.
Design and Build Quality
The OM SYSTEM Olympus OM-3 boasts a vintage-styled, premium metal body that not only provides aesthetic appeal but also durability against the elements. With an IP53 rating, it is dustproof, splashproof, and freezeproof, making it a great choice for outdoor adventures. On the other hand, the Sony Alpha 6700 features a compact and lightweight design, ideal for photographers on the go. However, it lacks the same level of weather protection as its Olympus counterpart, which may limit its usability in harsh conditions.
Image Sensor and Processing
In terms of image capture, the OM SYSTEM Olympus OM-3 features a 20 MP Stacked BSI Live MOS sensor, paired with the TruePic X Processor to deliver impressive performance. Conversely, the Sony Alpha 6700 steps up the game with a 26 MP APS-C format Exmor R back-illuminated CMOS sensor, which offers enhanced detail and low-light performance. The Alpha 6700's BIONZ XR processing power further enhances image quality, making it an excellent option for those who prioritize clarity and depth in their photos.
Video Capabilities
When it comes to video recording, the Sony Alpha 6700 excels with its capability to shoot 4K at 60p and high frame rate 4K at 120p, providing filmmakers with versatile options for shooting high-quality content. It can also record in 6K oversampled 4:2:2 10-bit, which is a significant advantage for serious videographers. The OM SYSTEM Olympus OM-3, while capable of video shooting, does not match the versatility and quality offered by the Alpha 6700, making it less suitable for those whose primary focus is video.
Creative Features
The OM SYSTEM Olympus OM-3 stands out with its range of computational photography features, including Live ND, Live Composite, and Focus Stacking. These features allow photographers to experiment creatively and achieve unique effects that enhance their storytelling. Additionally, the Creative Dial provides various control options for color profiles and art filters. In contrast, the Sony Alpha 6700 focuses on high-performance technology, emphasizing AI subject recognition and tracking rather than extensive creative features. This makes the OM-3 a better choice for those who enjoy creative experimentation in their photography.
Performance in Low Light
The OM SYSTEM Olympus OM-3's 20 MP sensor, while effective, may struggle slightly compared to the Sony Alpha 6700 in low-light situations. The Alpha 6700's 26 MP sensor is designed for better low-light performance thanks to its back-illuminated design, which allows more light to hit the sensor. This advantage is crucial for photographers who often shoot in dimly lit environments or during evening hours, making the Alpha 6700 a more reliable choice in such conditions.
Target Audience
The OM SYSTEM Olympus OM-3 is tailored for adventure and travel photographers who need a reliable, weather-sealed camera that can withstand the elements while offering creative features. Its robust design and creative capabilities make it appealing for outdoor enthusiasts and those who enjoy experimenting with different photography techniques. On the other hand, the Sony Alpha 6700 is designed for photographers and videographers who value advanced technology, particularly in AI and high-resolution imaging. Its lightweight design and video capabilities make it particularly appealing for those who need a portable yet powerful camera.
Which should you buy?
Choosing between the OM SYSTEM Olympus OM-3 and the Sony Alpha 6700 ultimately comes down to your specific needs as a photographer. If you prioritize a rugged design and creative features for outdoor photography, the OM-3 is the way to go. However, if your focus is on superior image quality, advanced video capabilities, and a lightweight body, the Sony Alpha 6700 is likely the better choice. With a price difference of about $201, you should weigh the features against how you plan to use the camera.
