Thypoch RF Simera 28mm f/1.4 Review

The Canon Thypoch Simera 28mm f/1.4 is a weird little lens. It's a fast, full-frame prime with a manual focus design and a vintage look, but it's made for modern Canon RF cameras. You're getting that classic f/1.4 light gathering in a surprisingly light package.

This isn't your typical autofocus workhorse. It's a deliberate, hands-on tool built for photographers who want to slow down and control every part of the shot. The silver finish and compact size give it serious character, but it comes with some big trade-offs.

The performance story is all about the aperture and bokeh. That f/1.4 max aperture lands in the 88th percentile, so it's seriously fast and great in low light. The bokeh quality is its superstar feature, sitting in the 98th percentile. The 14-blade diaphragm helps make backgrounds look creamy and smooth. But the optical performance is just okay at the 68th percentile, and the manual-only focus puts it in the bottom half for autofocus capability. You trade speed for control.

At $399, it's a niche product. You're paying for that specific f/1.4 character and manual feel. If you absolutely need autofocus or stabilization, this isn't worth it. But if you're a videographer who loves manual lenses, or a stills shooter who enjoys the process, the price is fair for the optical quality you get in the bokeh department.

Compared to the Viltrox 35mm f/1.7 or the Meike 55mm f/1.8, you're giving up autofocus for a wider angle and a faster aperture. The Thypoch is more specialized. The Viltrox and Meike options are better all-rounders if you need AF. Against something like the Yongnuo 35mm f/1.8 for Sony, the Thypoch wins on pure bokeh quality and build feel but loses hard on convenience. It's a lens for a specific mood, not for everyday versatility.

Buy this if you're a Canon RF shooter who loves manual lenses, values beautiful bokeh above all else, and doesn't mind giving up autofocus. It's perfect for portrait artists, certain videographers, and anyone who wants to add a tactile, vintage-inspired prime to their kit. Skip it if you need AF for fast-moving subjects, shoot in bad weather, or just want a do-it-all lens.
