Canon EOS 90D

Pros

• Exceptional battery life that significantly outperforms mirrorless competitors
• Fast burst shooting speeds of 10-11 fps, suitable for action and wildlife
• Supports uncropped 4K video and 1080p at 120fps for slow motion
• High-resolution sensor provides great detail for photography and cropping
• Native compatibility with EF-S lenses without needing an adapter

Cons

• Heavy and bulky, especially when paired with high-quality glass
• High price point makes it difficult to justify against feature-rich mirrorless alternatives
• Incremental upgrade for users already owning an 80D
• Autofocus and tracking performance lag behind the latest mirrorless systems

Caveats

• The DSLR platform is increasingly seen as secondary to mirrorless (EOS R series) for future lens development
• Low-light performance is a noted concern for some users transitioning from other bodies
• Isolated reports of shutter malfunctions within a few years of use

Best for

• Photographers with an existing collection of EF-S lenses
• Users who need a rugged body with long-lasting battery for all-day shooting
• Action and sports photographers on a budget who prefer an optical viewfinder

Avoid if

• You prioritize a lightweight and portable camera kit
• You are building a new camera system from scratch (mirrorless is generally recommended)
• You require the most advanced AI-subject tracking and eye-autofocus
