Recently, professional nature photographer, guide, and writer Keenan Hursh embarked on an extensive wildlife photography workshop in India, an expedition that served as an ideal real-world testbed for the latest innovations. As a trip leader for Backcountry Journeys, Hursh frequently navigates some of the planet’s most iconic natural landscapes, guiding small groups of photographers. His recent "Tiger Safari" workshop, exploring Bandhavgarh and Kanha National Parks in Madhya Pradesh—regions renowned globally for their Bengal tiger populations—presented a unique opportunity to conduct a direct, side-by-side comparison of two significant Canon mirrorless camera bodies: the Canon EOS R5 Mark II and its acclaimed predecessor, the original Canon EOS R5. This intensive field comparison aimed to evaluate how these "iconic and beloved cameras stack up against one another" under the challenging and unpredictable conditions of wildlife photography.
The India Expedition: A Testbed for Innovation
For many wildlife enthusiasts, a journey to photograph tigers in their natural habitat represents the pinnacle of photographic ambition. Keenan Hursh’s recent workshop fulfilled this aspiration, commencing in Delhi where participants converged before embarking on a rigorous 10-day itinerary. The expedition involved daily safari drives through two of India’s premier tiger reserves, Bandhavgarh and Kanha National Parks, situated in the central Indian state of Madhya Pradesh. These parks, while sharing a common abundance of tigers, each possess distinct ecosystems and offer varied photographic opportunities. Bandhavgarh, known for its high tiger density and rugged terrain, contrasts with Kanha’s sprawling meadows and dense sal forests.
Throughout the workshop, participants were fortunate to encounter a remarkable total of 15 individual tigers, exceeding initial expectations and providing numerous intimate photographic moments in both parks. Beyond the elusive big cats, the diverse Indian wilderness yielded a plethora of other mammalian and avian subjects, contributing to an exceptionally productive and enjoyable experience. Hursh reported encountering over 25 new species within the first day alone, highlighting the rich biodiversity of these regions. Such expeditions are not merely about capturing images but also about immersing oneself in true wilderness, observing animals in their natural state, and fostering a deeper appreciation for conservation. The demanding nature of these environments, characterized by varying light conditions, rapid animal movements, and sometimes challenging vantage points, made it an ideal scenario to rigorously test advanced camera equipment.
Strategic Gear Selection: The Tools of the Trade
Effective wildlife photography necessitates meticulous preparation and the selection of appropriate gear tailored to potential scenarios. For his India trip, Hursh ensured he was equipped with a comprehensive arsenal, balancing capability with the practical constraints of international travel and domestic flight weight restrictions. This included selecting camera bodies offering the required performance, lenses providing optimal focal lengths for diverse compositions, and essential accessories to maximize success.
Hursh’s primary photography gear for the trip included his two personal Canon EOS R5 bodies, augmented by a Canon EOS R5 Mark II rented from Lensrentals.com. This rental decision stemmed from a prolonged interest in the R5 Mark II, following its release. Having extensively utilized the original R5 bodies for several years, Hursh lauded them as a "phenomenal camera" and an "exponential upgrade" from his previous DSLR setup. Initially, Hursh had opted against upgrading to the Mark II, perceiving the performance increases as minimal relative to the cost, especially considering the requirement for new battery types. However, positive feedback from peers reignited his curiosity, prompting the decision to undertake a direct field comparison. This hands-on evaluation in the crucible of a tiger safari offered invaluable insights into the practical differences between the two generations of Canon’s high-performance mirrorless cameras.
Deep Dive: The Canon EOS R5 – A Benchmark Performer
The original Canon EOS R5, launched approximately six years ago, quickly established itself as a flagship mirrorless camera, setting new benchmarks for professional use. Hursh’s long-term experience with two R5 bodies across diverse environments—from fast-paced wildlife encounters to extended astrophotography exposures, and in extreme temperatures ranging from over 100°F to below -30°F, across deserts and wet coastlines—attests to its robust performance and reliability. For wildlife photography, a discipline that heavily taxes camera and lens capabilities, the R5 has consistently delivered high-quality results.
Key attributes that make the Canon R5 a formidable tool for wildlife photography include its sophisticated AI-assisted autofocus (AF) capabilities, offering capable and accurate subject and eye detection. It boasts a respectable maximum burst rate of 20 frames per second (fps) when utilizing the electronic shutter, coupled with a high-resolution 45-megapixel (MP) full-frame sensor. The camera’s low-light performance is solid, handling higher ISO values effectively, and it incorporates excellent in-body image stabilization (IBIS). These features collectively have enabled Hursh to capture a vast array of high-quality images over the years. Even with the introduction of its successor, the R5 continues to hold its own, demonstrating remarkable longevity in a rapidly evolving market.
Despite its many strengths, Hursh’s extensive field use revealed a few minor areas for potential improvement. One functional annoyance noted was the cumbersome default method of switching between photo and video modes, which, in critical wildlife moments, could lead to missed opportunities. While customizable, the out-of-the-box experience was less than ideal. Another observation related to shooting with the electronic shutter: the absence of auditory feedback made it challenging to ascertain if images were being captured, compounded by intermittent blackouts in the electronic viewfinder (EVF), disrupting continuous visual tracking of subjects. While not deal-breakers, these aspects impacted the fluidity of the shooting experience. Furthermore, while the R5’s AF system is highly capable, it occasionally exhibited a "jumpy" behavior or failed to consistently identify subjects or eyes, leaving room for enhancement in reliability and smoothness. These, Hursh emphasizes, are minor complaints but significant enough to be noted after prolonged professional application, moving beyond common, often mitigated issues like overheating.
Introducing the Next Generation: Canon EOS R5 Mark II – Elevating the Standard
The Canon EOS R5 Mark II represents the natural evolution of its predecessor, and Hursh’s week-long field test in India positioned it as "great plus," arguably exceptional, particularly for wildlife photography. While the original R5 was a strong foundation, the Mark II delivered a superior overall experience, with improvements that, while not always "stark as night and day," were immediately noticeable and significantly enhanced the shooting process.
The R5 Mark II retains the core strengths of the original, including the same resolution, excellent IBIS, identical EVF and LCD resolution and quality, and a robust magnesium alloy body with quality weather sealing. The most impactful enhancements, however, are found in its performance and user interface.
Foremost among these improvements is the significantly upgraded autofocus system. The R5 Mark II’s AF capabilities were deemed "second-to-none" and "absolutely stellar" for wildlife photography. It demonstrated faster acquisition, enhanced accuracy, superior reliability, and smoother tracking compared to the R5. The camera proved far more adept at identifying and maintaining focus on subjects, even allowing seamless switching between multiple identified targets, with a noticeable reduction in erratic "jumping." For photographers where AF performance is a critical differentiator, the Mark II unequivocally takes the lead.
Another lauded feature is the introduction of pre-capture functionality. Initially underestimated, this proved to be a "game-changer" for specific scenarios, enabling the capture of moments previously deemed impossible. Hursh cited instances of successfully photographing small birds taking flight from perches, an achievement that would have been unfeasible with the R5. Pre-capture dramatically increases the probability of securing critical action shots involving fast-moving or unpredictable wildlife.
The redesigned user interface, specifically a dedicated photo/video switch, was also highly appreciated. Even for photographers primarily focused on stills, this thoughtful design improvement streamlines workflow and prevents missed shots that could occur with the R5’s more convoluted switching mechanism.
Perhaps the most significant technological upgrade in the R5 Mark II is its new stacked sensor. While maintaining the same 45MP resolution, this sensor unlocks several key advantages. It elevates the electronic shutter’s burst rate from 20 fps to a remarkable 30 fps, a substantial increase that can significantly impact the capture of high-speed action. Crucially, when using the electronic shutter, images are no longer compressed to 12-bit RAW files but retain their full 14-bit data, offering greater post-processing flexibility. Furthermore, the stacked sensor eliminates the blackouts in the EVF during continuous shooting, providing a "blackout-free, more natural and enjoyable experience" by allowing photographers to continuously track subjects without interruption. A minor yet appreciated ergonomic improvement is the option to enable an audible shutter noise for the electronic shutter, addressing a previous complaint about the R5’s silent operation.
