This size differential is more than cosmetic. The FP1’s ultra-thin profile favors ultra-light carry and discreet street photography, but sacrifices substantial grip and physical controls. Its slender body offers limited tactile feedback, relying heavily on digital interface navigation. Conversely, the RX100 IV’s increased depth affords a more substantial grip and physically distinct control dials, enhancing in-hand stability and operational confidence during extended shooting sessions.
Panasonic's FP1 lacks an electronic or optical viewfinder, necessitating sole reliance on its fixed 2.7-inch LCD, which can complicate bright-light framing. The RX100 IV integrates a high-resolution (2.36M dots) pop-up electronic viewfinder with 100% coverage and 0.59x magnification, significantly improving composition precision and shielding from ambient light. This difference is pivotal for landscape, wildlife, and professional work where composition accuracy is paramount.
Sensor Technology and Image Quality Fundamentals
Sensor selection heavily influences photographic output, dictating resolution, low-light performance, and dynamic range. The FP1 employs a 1/2.3-inch CCD sensor measuring 6.08 x 4.56 mm, covering a 27.72 mm² area and capturing 12 megapixels. The smaller sensor inherently confines light-gathering ability and dynamic range, limiting high-ISO usability and producing more noise in challenging lighting.
Conversely, the RX100 IV features a much larger 1-inch BSI-CMOS sensor, 13.2 x 8.8 mm (116.16 mm² area) with 20 megapixels. The backside illumination architecture significantly improves sensitivity and noise handling. DXOMark benchmarks - while not available for the FP1 - confirm the RX100 IV’s 70 overall score, with 22.9 bits color depth and 12.6 EV dynamic range at base ISO, verifying excellent image fidelity for a compact.
Practically, the FP1’s sensor tends to limit output to daylight or well-lit indoor conditions with base ISO 80–200 for optimal quality. The RX100 IV accommodates ISO up to 12,800 natively (and boosts to 25,600), maintaining usable image quality through computational noise reduction, making it suitable for low light, event, and night photography.
Autofocus Systems: Precision, Speed, and Reliability
Autofocus performance is critical across disciplines from wildlife tracking to macro focusing. The FP1 uses a contrast-detection system with 9 focus points and live view AF, but notably lacks face detection, continuous autofocus, or subject tracking features.
The RX100 IV advances with a hybrid AF system combining contrast-detection and phase detection elements (albeit without many cross-type points), offering 25 AF points, face detection, continuous AF, AF tracking, and selective AF area modes. Real-world tests underline the RX100 IV’s superior AF speed and accuracy, especially in continuous shooting and video autofocus.
The lack of manual focus on the FP1 further constrains creative control and precision in challenging focus scenarios. The RX100 IV offers manual focus options, facilitating macro and landscape photographers who require deliberate focus adjustments.
