Summary: If you value portability with easy-to-use touch controls, the Canon T7i is great. For rugged durability and tactile controls suited to fast-paced or extended shoots, the Nikon D300S still impresses.

Sensor and Image Quality: Technology and Resolution Differences

At the heart of any camera are the sensor and processor, which dictate image quality, noise performance, and dynamic range.

Sensor Size and Resolution

• Both cameras use an APS-C sensor, though Nikon’s sensor is slightly larger at 23.6x15.8mm compared to Canon’s 22.3x14.9mm.
• Canon T7i features a 24.2-megapixel sensor with the DIGIC 7 processor, promising higher resolution images (6000x4000 px) and improved noise handling.
• Nikon D300S houses a 12.3-megapixel sensor powered by the older Expeed processor, outputting images at 4288x2848 px.

I tested image sharpness, color fidelity, and ISO performance side-by-side. The T7i’s 24MP sensor resolves more detail in landscapes and portraits, with cleaner images at ISO 3200 and better color depth. The Nikon’s 12MP resolution is less forgiving for large prints or heavy cropping but retains excellent color rendering characteristic of Nikon’s CMOS sensors.

Dynamic Range and Low-Light Performance

• The Nikon documentation indicates a dynamic range around 12.2 EV (excellent for its era) but limited max native ISO at 3200, making it less suitable in very dim conditions.
• The Canon T7i’s newer sensor extends ISO up to 25600 natively, allowing cleaner performance in low light with less aggressive noise reduction than I expected on the Rebel series.

Image Formats and Flexibility

• Both cameras shoot RAW, essential for professional editing.
• The T7i supports multiple aspect ratios (1:1, 4:3, 3:2, 16:9), giving creative framing options in-camera, while the D300S sticks to 3:2.

In practice, I recommend the Canon T7i for photographers who prioritize resolution and dynamic range, especially for landscapes and portraits requiring detail fidelity. The Nikon holds ground for those who prioritize color consistency and detailed-to-mid-sized prints.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus is a key differentiator, particularly in action, wildlife, and sports photography.

• Canon T7i packs 45 autofocus points with all being cross-type, including face detection and continuous tracking in live view.
• Nikon D300S uses 51 focus points - tied to one of the top AF systems in its class at release - but only 15 are cross-type sensors.

Hands-on test: In daylight, both systems lock focus quickly for still subjects, but the Canon’s Dual Pixel CMOS AF in live view provides silky-smooth focusing and accurate eye detection for portraits - something the Nikon lacks.

For wildlife and sports, the Nikon is rock solid with faster max shutter speeds (1/8000s vs 1/4000s on Canon) and a slightly higher continuous shooting speed (7fps vs 6fps), offering an edge shooting fast-moving subjects. However, the T7i gives better subject-tracking performance due to face and eye AF.

Summary:

• Use the Canon T7i if you rely heavily on live view autofocus, portraiture with human subjects, and want beginner-friendly face/eye detection.
• Opt for the Nikon D300S if you prioritize phase-detection AF accuracy for fast-moving wildlife or sports, especially using the optical viewfinder.

Viewfinder and Display: Traditional Optics vs Modern Screens

• The Nikon D300S employs a bright, large pentaprism optical viewfinder with 100% coverage and 0.63x magnification. It delivers a clear, accurate framing experience beloved by traditionalists.
• Canon T7i offers a pentamirror optical viewfinder with 95% coverage and 0.51x magnification - not as bright or immersive but adequate for casual shooting.

The Canon counters this with a fully articulating touchscreen LCD boasting 1040k dots for sharp live view and menu control, boosting composition options and video shooting ease. Nikon’s fixed 920k dot LCD is excellent in clarity but less flexible.

My testing notes: I found the Nikon viewfinder better for manual focus, sports tracking, and battery conservation. The Canon screen excels for vlogging, macro, and awkward angles, particularly in bright scenes.

Burst Rates, Buffer, and Shutter Speeds for Action and Sports

Continuous shooting and shutter speed range are crucial for capturing sports, wildlife flights, and decisive moments.

• Nikon D300S shoots at 7fps with an 8000 max shutter speed, ideal for freezing fast motion and bursts of rapid frames.
• Canon T7i caps at 6fps and 4000 max shutter speed, sufficient for everyday action but less optimal in fast-paced pro environments.

The Nikon has a larger buffer and faster card access via dual slots (CF + SD), while Canon only uses a single SD card slot.

In my prolonged shooting tests at a local soccer game, the Nikon maintained faster sequences and more consistent AF tracking under stress. Canon’s buffer fills sooner, requiring brief cooldowns.

Video Capabilities: Moving Image Quality and Features

For hybrid shooters, video performance is a critical consideration.

• Canon T7i offers Full HD 1080p recording at up to 60fps with H.264 compression and microphone input. The DIGIC 7 processor allows for decent video autofocus and clear audio recordings.
• Nikon D300S provides only HD 720p video at 24fps with older Motion JPEG format and microphone input but lacks modern codecs or full HD capabilities.

Additionally, the Canon features better video usability with touchscreen autofocus during filming and a fully articulating screen, which is invaluable for vloggers or run-and-gun shooters.

In practice, for serious video, the Canon T7i is clearly better suited. Nikon’s video is functional for casual clips but dated by today’s standards.
