Moving beyond handling, the sensor lies at the heart of image quality. Let’s dissect the sensor technologies and their implications for your photography.

Sensor Technology and Image Quality: Micro Four Thirds vs. APS-C

The GH4’s Micro Four Thirds sensor measures 17.3×13mm with a resolution of 16MP using CMOS technology. This contrasts with the Pentax ist DL2’s APS-C CCD sensor at 23.5×15.7mm and a 6MP resolution. While the Pentax’s sensor is larger, the difference in technology and resolution tilts the balance in favor of the GH4 for overall image flexibility.

What this means practically:

• The GH4’s CMOS sensor offers faster readout speeds, better high ISO performance (up to 25600 native ISO), and supports sophisticated features like 4K video.
• The Pentax’s CCD sensor, while known for excellent color rendering and pleasing tonality, is limited by its lower resolution and poorer noise control at high ISO.
• The larger sensor area on the Pentax offers potential for better depth of field control at equivalent focal lengths, but the GH4’s higher megapixels provide sharper images and more detailed cropping freedom.

Our tests confirm that the GH4 delivers superior dynamic range (~12.8 stops) and better color depth (~23.2 bits) compared to the Pentax’s less than 12 stops and 22.9 bits.

Overall, if resolution and video capabilities matter to you, the GH4’s sensor has a notable edge. Now, let’s see how the cameras perform in actual shooting scenarios across key photography disciplines.

Portrait Photography: Rendering Skin Tones and Capturing Expression

Portrait photography demands smooth skin rendering, accurate eye detection, and pleasing bokeh. The GH4 utilizes 49 autofocus points, full contrast-detection AF with face detection, and the ability to track subjects with continuous AF. The Pentax ist DL2, with just 5 phase detection points and no face or eye detection, relies heavily on manual focus finesse.

Real-world observations:

• The GH4’s face and eye detection allow you to focus precisely on eyes - a win in group portraits and shallow depth-of-field styles, especially given its 2.1x crop factor lenses.
• The Pentax requires more manual AF involvement or confirmation due to limited AF points and no subject tracking.
• Bokeh quality on GH4 depends on lens choice; Micro Four Thirds lenses often yield less creamy bokeh than full-frame but can be excellent with fast primes.
• Pentax’s APS-C sensor can deliver shallower depth of field at comparable apertures but with lower resolution detail.

If portraits with smooth skin tones and quick, accurate focus are your priority, the GH4’s autofocus system combined with lens options offers more flexibility and creative freedom.
