Question 1

Is f/2.8 noticeably better than f/4 on a medium format lens?

Accepted Answer

Yes, and on medium format the difference is amplified. f/2.8 lets in twice as much light as f/4, which matters in low-light reception halls or shaded outdoor ceremonies. Beyond exposure, f/2.8 also tends to be sharper wide open than a comparable f/4 design when you need to shoot in challenging light without stopping down. The trade-off is a thinner depth of field — on a large medium format sensor, f/2.8 produces very shallow focus, so accurate autofocus matters more than it would on a crop-sensor camera.

Question 2

Does the Phase One Schneider 80mm f/2.8 AF work on both Phase One and Mamiya 645 bodies?

Accepted Answer

The lens uses the Phase One / Mamiya 645 mount, so it is mechanically and electronically compatible with bodies in that system. Autofocus and electronic communication function correctly on Phase One XF and DF bodies. On older Mamiya 645 bodies, performance can vary — autofocus typically works but some users report less consistent behaviour compared to newer Phase One bodies. If you are pairing it with an older Mamiya body, it is worth testing AF reliability before a critical shoot.

Question 3

What is the 80mm focal length equivalent to on a medium format sensor?

Accepted Answer

On a medium format 645-style sensor, 80mm sits roughly equivalent to a 50–55mm full-frame field of view — though this is an approximation, as the exact crop factor varies by digital back (IQ-series backs typically sit around 0.64×, giving roughly 51mm equivalent). That makes it a true 'standard' to slightly portrait-leaning lens — versatile for environmental portraits, group shots at weddings, and details. It is noticeably more immersive and less compressed than a 150mm, which is why

Question 4

How is the autofocus speed and accuracy on the Schneider 80mm f/2.8 AF?

Accepted Answer

Real-world users describe the AF on Schneider medium format lenses as fairly fast but noticeably noisy and aggressive in character — it is not the whisper-quiet, smooth AF you might expect from a modern mirrorless system. That said, it is accurate enough for professional portrait and wedding work where subjects are not in rapid erratic motion. For candid running-around shots of children or sports, a 35mm system with phase-detect AF would be a more practical choice. Going into a shoot knowing the AF sound and feel helps you set the right expectations.

Question 5

What is the difference between the Schneider 80mm f/2.8 AF and the Schneider 80mm LS Blue Ring version?

Accepted Answer

The Blue Ring variant is a later optically updated design that adds a leaf shutter (LS) for high-speed flash sync — it is also cited as the best-selling Phase One XF lens. The non-Blue-Ring 80mm f/2.8 AF, which is what this listing covers, lacks the leaf shutter but is still an optically capable, notably lightweight lens that professionals describe as insanely sharp. For photographers who do not need high-speed flash sync, the standard AF version is a cost-effective way into the same focal length.

Question 6

Is the Phase One Schneider 80mm f/2.8 a good lens for wedding photography?

Accepted Answer

It is a natural fit for wedding work on a medium format system. The f/2.8 aperture handles indoor ceremony light and evening receptions without forcing you to push ISO uncomfortably high. The 80mm focal length gives a flattering perspective for couple portraits and detail shots. Autofocus means you are not manually hunting focus during fast-moving moments. The main consideration is that medium format bodies are heavier than 35mm systems, so stamina during a full wedding day is a practical factor to think about.

Question 7

Is buying a used Phase One Schneider 80mm f/2.8 AF a safe choice?

Accepted Answer

Schneider-Kreuznach glass is built to professional standards and holds up well over time. A used copy that has been professionally inspected and individually photographed gives you a clear picture of its condition before you commit. On Camera-tweedehands.nl every second-hand lens comes with a minimum 12 months warranty, so you are not buying blind. The main thing to verify on any pre-owned medium format lens is the condition of the mount contacts and the glass elements — both are checked during inspection here.

Question 8

What other Phase One lenses pair well with the 80mm f/2.8 AF for a wedding or portrait kit?

Accepted Answer

A practical two-lens portrait and wedding kit on the Phase One / Mamiya 645 system would add the Phase One 35mm Blue Ring for wide environmental and venue shots, and the Phase One 150mm for tighter compressed portraits and ceremony candids from a respectful distance. If you need macro capability for ring and detail shots, the Phase One 120mm f/4 AF Macro covers that without needing a separate dedicated macro body. The Phase One 240mm is more specialist — useful for outdoor ceremonies where you are shooting from further back.
