Excerpt: In the early summer of 2013, Pentax expanded its commitment to the compact Q-mount Camera System by announcing the brand new Q7. Available now through Pentax's Color to Order™ system, you can configure your personal Q7 with 120 different color combinations. Features include a 12.4 megapixel BSI CMOS image sensor, their Q-mount interchangeable lens system, Full 1080p HD Video Recording, 5 frames per second High-Speed Burst Shooting, an ISO sensitivity up to ISO 12800, 19...
Summary: Throughout this review we have taken a very close look at the Pentax Q7's features and capabilities. Now it's time to take a step back and look at the big picture. We've shown that the Q7 has been much improved compared to the original Q, but now we must determine how it fares on its own, and when compared to other cameras currently on the market.
Pros: Very light and compact, Good image quality for its size, Low noise through ISO 800, Ability to adapt DSLR lenses, Full manual video controls, On-demand video autofocus, Very fast autofocus, Feature-packed user interface, Many DSLR-like customization options, Fast overall performance, Marked improvement over the Pentax Q/Q10, Comfortable grip, Buttons relatively easy to press, Built-in mechanical Shake Reduction, Sensor dust removal, DNG RAW support, Customizable in 12...
Cons: Small lens selection (1 quality prime, 2 quality zooms), Not available in a kit with the 01 prime lens, Requires 2 hands to operate, Kit zoom lens suffers from distortion, flare, and fringing, Images still not detailed enough for cropping, Tendency to overexpose / blow highlights, JPEG files over-sharpened by default, Poor video image quality, Poor video sound, Not pocketable with zoom lens, No electronic viewfinder option, No dedicated optical viewfinder, Low-resolut...
Summary: Conclusion The Pentax Q7 is in a precarious predicament. Should it be compared to other ILCs due to its interchangeable lens system or to point and shoots due to its sensor size? My initial reaction is to compare it to other ILCs. In that case, I believe it rests pretty close to the middle of the group. I tend to prefer the fast AF of the Olympus Pen cameras over the Q7.
Pros: Good image quality, although not consistent, Small and compact, Easily transportable, Very expandable especially when used with Q-mount adaptors
Cons: Slow AF speeds, High ISOs lead to soft images, Good image quality, although not consistent
Summary: The Pentax Q7, and by extension the whole of the Q system, is a difficult thing to summarise. On the one hand you have a surprisingly capable little camera with a good range of features, excellent build quality, performance and handling, and image quality that compares well to most high-end compacts.
Summary: The Pentax Q7 does well in everyday shooting, delivering image quality that's generally as good as the best enthusiast compacts. However, it under delivers for the entry-level ILC class in terms of resolution and high-ISO performance. Though we had few serious complaints about its performance, it's hard to recommend among so many excellent fixed and interchangeable-lens cameras that cost about the same.
Conclusion: If you're after a cute compact system camera which takes reasonable pictures in good light, then the Q7 is a good choice. Unfortunately, for Pentax, there are plenty of better options currently on the market. The best, if you're in the market for a very small, but still well performing camera, is the Panasonic GM1 which manages to fit a very large (by comparison) sensor in a body which isn't too much bigger than even the Q7's diminutive stature.
