Canon RF 85mm f/1.2L USM: The Bokeh King
When Canon announced the RF 85mm f/1.2L USM, the photography world collectively gasped. This wasn’t just an update to their existing 85mm lineup—it was a reimagining of what an 85mm lens could be. After shooting with it for countless sessions, I can confidently say it lives up to the hype.
Build Quality and Design
The first thing you’ll notice about the f/1.2 is its substantial presence. This is a lens that means business, weighing in at nearly 2.6 pounds. The all-metal construction feels premium in every way, with the kind of build quality that assures you this lens will withstand years of professional use.
I’ve shot with this lens in everything from studio environments to dusty outdoor locations, and its weather sealing has never let me down. The dust and moisture resistance give me confidence when shooting in less-than-ideal conditions—a must-have for working professionals.
The control ring is smooth and responsive, perfect for making manual adjustments while keeping your eye on the viewfinder. I particularly appreciate the customizable control ring, which I’ve set to adjust ISO in my shooting profile.
Optical Performance
Where the f/1.2 truly shines is in its optical performance. The wide f/1.2 aperture isn’t just a marketing gimmick—it delivers incredibly beautiful, dreamlike bokeh that I’ve found impossible to replicate with any other lens.
During a recent portrait session, I shot the same subject with both lenses, switching back and forth to compare. The f/1.2 produced a background separation that was noticeably more pronounced, with that creamy, ethereal quality that makes portraits truly pop.
Sharpness is exceptional, even when shooting wide open. I’ve printed large format portraits from files shot at f/1.2, and the detail in the eyes is breathtaking. While some lenses need to be stopped down to achieve optimal sharpness, the f/1.2 delivers stunning results from f/1.2 onward.
Autofocus Performance
One of my initial concerns with such a wide aperture was autofocus performance. Moving those massive glass elements quickly and accurately is no small feat. I’m happy to report that Canon’s Dual Pixel CMOS AF system handles this lens beautifully.
In my portrait sessions, the autofocus is fast and decisive, locking onto eyes with remarkable precision. Even in challenging lighting conditions, I’ve found the hunting to be minimal. That said, it’s not quite as snappy as the f/1.4, which we’ll discuss in more detail later.
Low Light Capabilities
This is where the f/1.2 truly separates itself from the pack. The extra light-gathering ability makes a significant difference in low-light situations. I’ve shot indoor events where the f/1.2 allowed me to capture clean images at lower ISOs than would have been possible with the f/1.4.
During a recent sunset portrait session, I was able to keep shooting well after other photographers had packed up, simply because the f/1.2 was gathering so much more light. The resulting images had a magical quality that perfectly captured the twilight mood.
Special Features: The DS Version
Canon also offers a DS (Defocus Smoothing) version of this lens, which I’ve had the opportunity to test. The DS version uses a special coating to further smooth the bokeh, creating even more dreamlike out-of-focus areas. While it’s an impressive technical achievement, I found it to be a bit too specialized for my general portrait work, though it could be perfect for photographers with a very specific aesthetic.
Pros and Cons of the f/1.2
Pros:
- Unmatched background separation and bokeh quality
- Exceptional sharpness even at f/1.2
- Superior low-light performance
- Premium build quality and weather sealing
- Unique optical character that’s hard to replicate
Cons:
- Significantly heavier and bulkier
- No image stabilization
- Higher price point
- Slightly slower autofocus than the f/1.4
- Can be overkill for some photographers’ needs
Canon RF 85mm f/1.4L IS USM: The Versatile Performer
When Canon released the RF 85mm f/1.4L IS USM, many photographers wondered where it fit in the lineup. After extensive shooting with this lens, I can tell you it’s not just a compromise—it’s a brilliantly engineered lens that stands on its own merits.
Build Quality and Design
The f/1.4 is noticeably smaller and lighter than its f/1.2 sibling, making it a more practical choice for long shooting days. At 950g, it’s still a substantial lens, but it’s much more manageable for handheld work and travel.
The build quality is excellent, with the same weather sealing as the f/1.2. I’ve used this lens in light rain without any issues, and it feels durable enough for professional use. The control ring is well-damped and customizable, just like on the f/1.2.
One design aspect I particularly appreciate is the smaller 77mm filter thread, which makes filters more affordable and easier to handle than the 95mm filters required by the f/1.2.
Optical Performance
While it doesn’t quite match the f/1.2 in terms of pure bokeh quality, the f/1.4 still produces beautiful background separation. The difference is noticeable in side-by-side comparisons, but in isolation, the f/1.4’s bokeh is still gorgeous by any standard.
Sharpness is excellent across the frame, even when shooting wide open. I’ve found that by f/2.8, it’s virtually indistinguishable from the f/1.2 in terms of sharpness. For most portrait work, this is more than adequate.
One area where the f/1.4 actually outperforms its bigger sibling is in chromatic aberration control. I’ve noticed less purple fringing in high-contrast situations with the f/1.4, which can save time in post-processing.
Autofocus Performance
This is where the f/1.4 really shines. The autofocus is noticeably faster and more decisive than the f/1.2, making it ideal for situations where speed is critical. I’ve used this lens for event photography and even some sports work, and it never missed a beat.
The autofocus is also quieter, which can be important in certain shooting situations like ceremonies or quiet environments. For photographers who shoot a mix of portraits and action, the f/1.4’s autofocus performance might be the deciding factor.
Image Stabilization
Perhaps the most significant advantage of the f/1.4 is its built-in image stabilization, rated for up to 5 stops of compensation. This feature alone makes it a more versatile lens, allowing for sharp handheld shots at slower shutter speeds.
I’ve tested this extensively, and I can consistently get sharp images at shutter speeds as low as 1/15s—something that’s nearly impossible with the f/1.2 without a tripod. This makes the f/1.4 a better choice for environmental portraits, travel photography, and any situation where you might be shooting handheld in less-than-ideal light.
Low Light Capabilities
While it can’t match the f/1.2 in pure light-gathering ability, the f/1.4 is still an excellent low-light performer. Combined with the image stabilization, it’s actually more versatile in many low-light situations because you can use slower shutter speeds hand-held.
During a recent indoor event, I found myself reaching for the f/1.4 over the f/1.2 because the combination of f/1.4 aperture and image stabilization gave me more flexibility in my exposure choices.
Pros and Cons of the f/1.4
Pros:
- Excellent balance of performance and portability
- Faster and quieter autofocus
- Built-in image stabilization (5 stops)
- More affordable price point
- Smaller filter size (77mm vs 95mm)
- Better chromatic aberration control
Cons:
- Slightly less impressive bokeh than the f/1.2
- Not as bright in extremely low light
- Still relatively heavy for an 85mm lens
- Lacks the “special quality” of the f/1.2

Head-to-Head Comparison: Real-World Performance
Numbers and specifications only tell part of the story. To truly understand the differences between these two exceptional lenses, I put them through their paces in real-world shooting scenarios. Here’s what I discovered:
Portrait Sessions
For traditional portrait sessions, both lenses excel, but with different strengths. The f/1.2 produces that magical quality that makes portraits truly stand out, with subject separation that’s simply unmatched. When I’m shooting portraits where the background is an important element of the composition, I find myself reaching for the f/1.2.
However, for longer portrait sessions, the lighter weight of the f/1.4 makes a significant difference. During a recent four-hour portrait marathon, I found myself much less fatigued when using the f/1.4, which allowed me to maintain my creativity and energy throughout the session.
Wedding Photography
Wedding photography is where the differences between these lenses become most apparent. I’ve shot several weddings with both lenses, and here’s my takeaway:
The f/1.2 is unbeatable for those special moments during the reception when you want to create magical, ethereal images. The way it renders out-of-focus background elements adds a dreamlike quality to wedding photos that couples absolutely love.
However, the f/1.4 is the more practical choice for most of a wedding day. The image stabilization is invaluable for dimly lit ceremonies, and the faster autofocus is crucial for capturing fleeting moments. During a recent wedding, I found myself using the f/1.4 for about 80% of the day, switching to the f/1.2 only for specific portraits during the golden hour.
Event Photography
For event photography, the f/1.4 is the clear winner in my experience. The combination of image stabilization and faster autofocus makes it much more versatile in the unpredictable environment of events. I’ve shot corporate events, concerts, and parties with both lenses, and the f/1.4 consistently delivered more keepers.
The lighter weight is also a significant factor during long events where you’re carrying the camera for hours on end. After shooting a 6-hour charity event with the f/1.2, my arms were noticeably more tired than when using the f/1.4.
