Pentax 645n vs. Contax 645: Best Medium Format Film Cameras for Weddings in 2025

If you’re a wedding photographer hoping to capture the timeless beauty of film in 2025, chances are you’ve considered the Pentax 645n or the Contax 645. Both cameras emerged in the early 2000s, giving you modern features like autofocus and built-in light meters—handy upgrades compared to older, fully manual film bodies. While both are beloved by medium format fans, each has its own strengths that might sway your decision on a busy wedding day.

Size, Cost, and Build

One of the biggest draws of the Pentax 645n is its relatively compact size. You can often find a used body for around $1,000 or less, making it more approachable if you’re conscious of your budget or want a lighter setup. Despite its age, the camera’s build has stood the test of time, proving it can handle heavy use without a hiccup.

On the other hand, the Contax 645 typically fetches a higher price—around $3,000 or more. That extra cost is partly because of the Zeiss Planar lens system, known for delivering razor-sharp images and rich contrast. If you’re after top-tier optics, it may be worth the splurge.

Autofocus and Low-Light Performance

During weddings, you don’t get second chances when key moments happen. The Pentax 645n generally handles low-light autofocus well, making it easier to grab candid shots on the fly. Meanwhile, the Contax 645 performs better in good light but can sometimes hunt for focus in dim settings. As a result, many Contax shooters opt for manual focus when the lights go down.

Lens Options and Aperture

The Contax’s 80mm f/2 lens is famous for its dreamy, shallow depth of field—ideal for romantic portraits. By comparison, the Pentax 645n often pairs with a 75mm or 45mm f/2.8 lens, producing a classic look but with slightly less background blur. If you crave that extra stop of softness, Contax might be your best bet, but the Pentax still delivers stunning results.

Final Thoughts

Both cameras excel at delivering the nostalgic charm of medium format film. The Pentax 645n offers a friendlier price tag and solid autofocus, while the Contax 645 boasts premium Zeiss lenses and the coveted f/2 aperture. Your decision ultimately hinges on budget, shooting style, and whether you’re comfortable switching to manual focus when needed. Either way, both systems continue to win the hearts of wedding photographers seeking that classic film aesthetic in 2025.
