Choosing Between the Hasselblad X1D II 50C and the YI M1: A Deep Dive from an Experienced Eye

In the crowded field of mirrorless cameras, two seemingly distant siblings - the high-end Hasselblad X1D II 50C and the budget-friendly YI M1 - invite a direct comparison that might surprise you. With nearly a $5,400 price gap and divergent target audiences, you might think such a matchup is apples to oranges. Truth be told, it’s more enlightening than you’d expect, especially if you’re weighing a serious investment or curious about what separates luxury medium format from accessible beginner gear.

Having extensively tested thousands of cameras over 15+ years, I find comparisons like these invaluable for stripping away the marketing fluff and getting to the core of what really matters in real-world photography. In this article, I’ll walk you through everything - from sensor technology to ergonomics, from autofocus chops to lens ecosystems - while keeping it friendly, practical, and directly relevant to your day-to-day shooting needs.

Let’s get to it.

First Impressions: Size, Design, and Handling Feel

Before you dive into specs and charts, how a camera feels in your hands often makes or breaks the entire experience.

Hasselblad X1D II 50C: This is a medium format camera, and it unmistakably carries that heft and presence. Measuring 150 x 98 x 71 mm and weighing 725g, the X1D II sits comfortably in the "not-quite-pocketable" range but remains surprisingly compact for a medium format body. Its rangefinder-style design aligns well with its heritage, giving it a clean, minimalist aesthetic that many pros appreciate. I find the grip to be deep enough to secure a solid hold, but don’t expect the bulky rubberized grips of typical DSLRs here - ergonomics favor elegance over brute force.

YI M1: On the opposite side of the spectrum, the YI M1 is outright petite: 114 x 64 x 34 mm at 350g. This makes it an increasingly rare breed of genuinely pocket-sized rangefinder mirrorless cameras, especially with interchangeable lenses. Light as a feather, it slips easily into a jacket pocket or small bag, and for street or travel photography enthusiasts prioritizing portability, this is a major win.

Verdict:

If size and handling are your numero uno criteria, the X1D II balances medium format weight with decent portability, while the YI M1 wins unequivocally on sheer compactness - perfect for photographers on the move or minimalists.

Sensor Size and Image Quality: The Heart of the Matter

At the core of any camera lies its sensor, and here is where our contenders diverge dramatically.

• Hasselblad X1D II 50C boasts a true medium format CMOS sensor measuring 44 x 33 mm, delivering 51 megapixels at a colossal 8272 x 6200 resolution. Medium format sensors like this have a sensor area of 1452 mm², dwarfing the 224.9 mm² of the YI’s Four Thirds sensor. The X1D’s 26.2-bit color depth, 14.8 stops dynamic range, and low-light ISO performance scoring 4489 (DxOMark scale) clearly mark it as a heavyweight champion of image quality.

• YI M1’s sensor is a 20MP Four Thirds CMOS, measuring 17.3 x 13 mm. Though much smaller, this sensor delivers respectable files in good light. The max resolution is 5184 x 3888 with native ISO up to 25600. However, its dynamic range and color depth lag behind more serious cameras, limiting its abilities in challenging lighting conditions.

Technical insights here indicate that the X1D II’s sensor size and processing allow for:

• Superior detail retention and greater cropping flexibility.
• Impeccable color fidelity typical of Hasselblad’s color science.
• Far better performance in shadows and highlights due to the extended dynamic range.
• Cleaner images at higher ISO levels - essential for low-light and studio photography.

The smaller sensor in the YI M1 means increased noise and less tonal nuance especially beyond ISO 1600-3200. That said, for standard daytime shooting and casual to enthusiast use, it punches above its weight class.

The Bodies and Control Layouts: Where Form Meets Function

A camera’s design isn’t just aesthetics - it affects speed, comfort, and your creative flow.

X1D II 50C: Controls are sparse but with a distinctly refined feel. The camera favors a minimalist approach - this is a clubs-for-thumbs kind of design where each button is well-placed but the camera invites you to use the rear touchscreen and menus for most settings. The electronic viewfinder (3670k resolution OLED) is sharp and immersive, covering 100% of the frame with a 0.87x magnification factor. The touchscreen is 3.6 inches with a 2360k dot resolution, responsive to touch, making navigation and AF point selection pleasantly intuitive.

YI M1: Controls are also minimal with a simplified button layout and no electronic viewfinder to speak of. You rely entirely on the rear 3.0-inch touchscreen (1040k dots) for framing and settings, which is perfectly fine for a budget mirrorless but does require careful handholding in bright sunlight. Having no EVF is a drawback for more serious shooters who need a real-time, eye-level view.

While the Hasselblad focuses on balanced professional ergonomics, the YI M1’s controls are clearly aimed at beginners or casual shooters wanting straightforward operation.

Autofocus and Performance Under Fire

Let’s talk about the technical guts where speed and accuracy really test the mettle in the field.

• X1D II 50C: Features a contrast-detection autofocus system with 117 focus points. It supports single AF, continuous AF, tracking, face detection, multi-area AF, and touch AF. Notably, it lacks phase detection autofocus and animal eye AF. Continuous shooting clocks in at a decidedly slow 2.7 fps, attributable to the large file sizes of medium format RAWs and the sensor readout speeds.

• YI M1: Uses contrast-detection AF as well with 81 focus points, but it does include face detection (unlike the Hasselblad). Continuous shooting is a more sprightly 5 fps, though buffering and write speeds are limited by the SD card and USB 2.0 interface.

From practical shooting experience:

• Hasselblad’s AF is precise, albeit slower. This slowness is a tradeoff for absolute accuracy with giant pixels and complex processing. It’s suited to slow-moving subjects, portraits, and studio work.

• YI M1’s faster burst and face detection make it more appropriate for casual portraits, street photography, and evolving scenes, though its AF struggles in low contrast and low light.

Picture this: trying to shoot wildlife or sports - both of these cameras are not designed for blazing fast autofocus or tracking like flagship DSLRs or sports-centric mirrorless systems. For wildlife photographers, the X1D II demands patience and the right lenses, while the YI M1 might frustrate with slower focus and lack of tracking.

Lens Ecosystems and Compatibility: The Glass Behind the Glamour

You can’t talk about cameras without acknowledging the lenses - arguably the most important creative tool.

• Hasselblad X1D II 50C: Uses the proprietary Hasselblad X-mount, designed for medium format lenses. There are currently 13 native lenses covering wide angle through telephoto, including several premium high-performance primes. The lenses are legendary for their optical quality - sharp, contrasty, and with gorgeous medium format bokeh and out-of-focus rendering.

• YI M1: Compatible with the vast Micro Four Thirds system, with access to over 100 lenses from Panasonic, Olympus, and other third parties. This opens up massive variety in focal length, aperture, and price points - from tiny pancake primes to more specialized options.

In short:

• The X1D II’s lens system is relatively compact but expensive. Getting the absolute best from that medium format sensor requires top-notch glass, and that comes at a price premium.

• The YI M1 offers the most expansive and versatile lens ecosystem in this comparison, with affordable and enthusiast-friendly glass to experiment with.

With limited budget? The Micro Four Thirds ecosystem is a clear winner. Need ultimate image quality with medium format? Hasselblad’s lenses deliver a rewarding but costly investment.

Display, Viewfinder, and Interface: Seeing and Interacting with Your Images

Your viewfinder and screen technology affect how accurately you can frame, focus, and review your shots.

• X1D II 50C: The 3.6-inch fixed touchscreen has higher resolution (2360k dots), which means crisper playback and menus. The EVF is best-in-class for medium format cameras, bright and detailed, which aids in precise manual focus and exposure preview.

• YI M1: Features a 3.0-inch touchscreen at 1040k dots, noticeably less sharp than the Hasselblad but perfectly functional. No EVF means you’re tethered to the rear screen, which can be disadvantageous in bright conditions or for handheld stability.

From countless sessions, a good EVF matters for professional work and outdoor shooting. The lack thereof on the YI M1 places it squarely in casual or enthusiast territory.

Durability and Weather Resistance: Should You Trust It in Harsh Conditions?

• Hasselblad X1D II 50C: Features weather sealing around buttons and joints, suitable for moderate resistance to dust and moisture - typical of a professional camera designed for outdoor shoots in varied environments.

• YI M1: No weather sealing or ruggedization. Treat it with care; it’s more vulnerable to environmental hazards.

Battery Life and Storage Flexibility: Made for Long Shoots or Quick Snaps?

• X1D II 50C: Has dual SD card slots supporting SD/SDHC/SDXC cards - a bonus for pro workflows looking for backup or overflow capacity. Battery life specifics are vague, but medium format cameras tend to drink power faster due to large sensors and EVFs. The solid build suggests reasonable stamina with a spare battery essential.

• YI M1: Single SD card slot with ample battery life (~450 shots per charge), impressive given its small size. Perfect for casual or travel users who prioritize weight savings and fewer accessories.

Video and Connectivity: How Do They Stack Up?

Video features often tip the scale for shooters who also want to dabble in filmmaking.

• X1D II 50C: Limited video capability: max resolution is 2720 x 1530 at 30p, with H.264 format. It includes microphone and headphone ports for audio monitoring - a thoughtful tool for serious video work, but the lack of 4K and any advanced video features makes it more of a stills-centric tool.

• YI M1: Impressively shoots 4K UHD (4096 x 2160) at 30p and supports time-lapse recording. Missing microphone or headphone jacks limits professional audio capture, but for casual 4K videos it meets expectations. Video codecs include MOV with H.264 compression.

Connectivity-wise:

• Hasselblad has built-in GPS and Wi-Fi (no Bluetooth), enabling geotagging and wireless transfer.

• YI M1 supports Wi-Fi and Bluetooth but lacks GPS.
