Canon 85 1.8 usm review năm 2024

As we mentioned in the introduction the test of the first specimen of the Canon 1.8/85, performed by us in 2006, was based on RAW files from the Canon 20D. It’s worth reminding here that in the case of tests on that body the decency level is placed at 30 lpmm and the best fixed-focal lenses could reach the values of 43-45 lpmm. The results, achieved by the Canon EF 85 mm f/1.8 USM, are presented below, in the form of a graph showing the performance in the centre and on the edge of the APS-C sensor.

As you see at the maximum relative aperture the image just brushes against full usefulness level. It’s enough you stop down the lens slightly and the image quality becomes flawless because by f/2.0 the MTF values got to almost 32 lpmm. On further stopping down the image quality improves, reaching its peak by f/5.6. The level of 40 lpmm can be hardly called record-breaking but it certainly allows to shot very sharp photos.

The difference between the image quality in the centre of the frame and on the edge of the APS-C sensor is not huge. If you want to enjoy fully acceptable sharpness you must remember about stopping down the lens to a bit above f/2.8.

The next test of the Canon 1.8/85 we conducted 4 years later and this time we used the full frame EOS 1Ds MkIII camera. It features exactly the same linear pixel density like the 20D. Its sensor is much newer, though, and with better software, so the results are by 1-2 lpmm higher than those achieved on the EOS 20D. You should remember this if you want to compare directly the results of different lenses.

The graph below shows the result the tested lens got in the frame centre and on the edge of full frame.

Even if you lowered the results, presented above, by 1-2 lpmm to compare them directly with those reached on the 20D, it is clear that the second specimen of the EF 85 mm f/1.8 lens that found its way to our editorial office is better. It is especially visible at the maximum relative aperture. When it comes to the MTF50 results the lens gets to the level of over 34 lpmm so it is able to provide fully useful images there. The highest image resolution we achieve by f/4.0-f/8.0 where the lens gets to 42 lpmm. “Prime” lenses, designed and produced nowadays, can reach the results of 46 lpmm on 1Ds MkIII (e.g. the expensive Canon 85L f/1.2 got 45.5 lpmm by f/4.0) so the Canon 1.8/85, tested here, lags a bit behind. The difference is so slight, though, that in the case of amateur uses it shouldn’t bother us at all.

The interesting thing is that when you buy this model you should check how a particular specimen of this lens fares by f/1.8. There are specimens which are just moderately useful there and also those which provide quite satisfactory images.

When it comes to the performance on the edge of full frame, the Canon EF 85 mm f/1.8 fares quite decently. It is full useful already from f/2.8 and on further stopping down it can provide really sharp images. The Canon performs significantly better here than the cheaper Samyang 1.4/85, faring a lot like the more expensive Sigma 1.4/85.

The Canon 85mm f1.8 lens is an absolute gem, and I can't help but give it a full five stars. Here's why this lens has become one of my all-time favorites: Stunning Image Quality: This lens delivers breathtaking image quality. The sharpness and clarity it produces are second to none. Whether I'm capturing portraits or shooting in low light conditions, the results are consistently outstanding. The wide f/1.8 aperture creates dreamy backgrounds with beautiful bokeh that make subjects pop. Versat ...

Fast short telephoto prime

Estimated reading time: 05 minutes.

October/2014 - The EF 85mm f/1.8 USM is a fixed short telephoto large aperture prime made for portraits. The dynamics change when you have to keep some distance from your subject, keeping facial expressions flattering. And with such a large aperture, the depth of field control is excellent, easily isolating your subject from the background, giving that very unique DSLR look to the images. It’s not large enough to became exotic, but that is a good thing: it’s compact, light, easy to use, with a price tag to match. It is adequate to most photographers looking for an easy to use equipment.

BUILD QUALITY

At 425g the 85mm f/1.8 USM is one of the nicest EF lens to work with. Not front heavy (it’s just 7cm long), it balances well on any DSLR, APS-C or full frame, and can be with you at all times. The design era is the same as the EF 50mm f/1.4 USM, but with a noticeable difference: the 85mm features a ring type USM, and nothing expands during focusing. So it’s more robust, reliable and silent; I wish every Canon EF lens worked as discretely as this one.

Its operation is simple like every USM lens: just a manual focusing ring (featuring full time manual) and the AF/MF switch. You can leave it at AF for the camera to control the focus, but at the same time you can compensate using the ring. The internal mechanism is precise and there’s no play between the ring and the focusing group. It is easy to nail focus, even with the short depth of field.

One of the main differences between the state of the art f/1.2L II USM and the basic f/1.8 USM lies on their autofocus. The f/1.2 uses a fly by wire ring that sends an electronic signal to the USM motor, moving the very heavy focusing group. But the f/1.8 is mechanically coupled, faster and with better feedback. That’s why the younger sister allows you to follow moving subjects, while the f/1.2 just can’t keep up. So it is better for action, sports, street photography, whereas the f/1.2 is better suited for portraits or whenever you don’t need to wildly change focusing distance.

“Bananeira” EOS 5D Mark II at f/1.8 1/200 ISO1600; f/1.8 AF performance allows candids like this.

At the rear, the metal mount is excellent for many mount/unmount cycles, with far less friction. At the front the ø58mm filters are small and inexpensive. The kit doesn’t include a lens hood, that must be purchased separately. It’s a good option as a backup lens for higher end kits, or to be with you at all times, be it on full frame or APS-C for portraiture work. And considering its results, it’s one of the best purchases on the entire Canon’s EF line. A complete IQ and operability package.

IMAGE QUALITY

“Girl on bike” at f/1.8 1/250 ISO1600.

With 9 elements in 7 groups, none with special form or glass, the 1992 EF 85mm f/1.8 USM was not made with the digital era in mind. It was from a simpler time, with no absurd demands from angry photographers about resolution and chromatic aberrations, when the images matter more than the manufacturer credentials: shallow depth of field, high contrast and balanced colours. And that’s what it delivers at any aperture, with a surprise: the resolution is spectacular with any digital camera, for large prints, be it from studios or a weekend with friends. Photos with 5D Mark II.

“re_Portrait” at f/1.8 1/4000 ISO100.

100% crop, some blooming wide open, but the resolution is very impressive.

Starting at f/1.8, the 85mm USM shows loads of light leaks around contrast areas, with some purple fringes around buildings, metallic objects or graphics. We have to stop it down to f/2.5 to eliminate it and the resolution gets uniform from edge to edge. It is good wide open, but it gets better stopped down. It’s not a lens for any aperture: remember to stop one or two EVs for maximum performance, especially under brightly lit scenes like during the day, under the sun shine.

“Doll” at f/1.8 1/400 ISO400.

100% crop, light blobs around highlights.

“Shot” at f/1.8 1/400 ISO100.

100% crop, a chaotic CA performance under too much light!

“Boy on bike” at f/1.8 1/160 ISO100.

100% crop, purple fringing around contrast edges.

But from f/2.8 and up we have very similar results to the L series, with details on clothes, portraits, street photography: anything that fits the depth of field, which remains short at 85mm. If you’re into short depths of field, get closer to your subject to really isolate it. The results are pictures with a single element in focus, good for close-ups, beauty shots, private compositions. It works even on APS-C cameras, as the 136mm equiv. makes it even easier to isolate the subject.

“Sartorialist” at f/2.8 1/200 ISO100.

100% crop, no signs of CAs.

“Jóia” at f/2.8 1/125 ISO100.

100% crop, lack of optical flaws.

“230 Super” at f/2.8 1/320 ISO100.

100% crop, chrome issues are gone at f/2.8.

Colours are balanced with the rest of Canon’s lineup, since the FD 50mm f/1.4. It’s a bit warmer than other brands and great for skin tones. It’s not yellow, ok? It’s just tuned for asian skin tones. The contrast overall is excellent from f/2.5 and the 85mm f/1.8 USM is very interesting to work together with the light, if it is part of your composition, appearing inside the frame.

“Hunter” at f/1.8 1/100 ISO160.

“w” at f/1.8 1/60 ISO1600.

“re_Portrait” at f/1.8 1/500 ISO100.

100% crop, some flaring at the short DoF.

The bokeh looks a bit complicated at longer focusing distances. There’re some repetitive lines, harsh edges on highlights and some axial CA on the background. It looks better in print, but if you’re outputting the images to the web, it is best to get closer to your subject; it gets smoother this way. Only top of the line L lenses get specific groups to enhance the out of focus appearance.

“Fiat” at f/1.8 1/800 ISO100.

100% crop, the details are impressive at f/1.8…

100% crop, but the bokeh gets complicated at longer focusing distances.

“XING” at f/1.8 1/320 ISO100.

100% crop, fuzzy background again.

“C2” at f/1.8 1/2000 ISO100.

VERDICT

A very flexible large aperture prime with a great distance for portraits, and perfect performance from f/2.5 and up. Considering its price and age, it can be a good choice if the focal length works for you. The 50mm f/1.8 II equivalency on APS-C is similar to the 85mm; so you can think about the EF 85mm on a future full frame upgrade. Try the 85mm on a zoom lens before you explore the shallow depth of field at f/1.8. Optically it is great. The results are on your hands. Nice shooting!

What is the Canon 85mm 1.8 good for?

With its wide aperture and fast focusing, the 85 f/1.8 works well for indoor Sports. This focal length is very good for portraits, and the Canon EF 85mm f/1.8 USM Lens makes a good portrait lens - excelling at head and head/shoulders portraits when mounted on a 1.3x or 1.6x FOVCF body.

Is A Canon 85mm 1.8 full frame?

Short-telephoto, portrait-length prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 136mm equivalent focal length.
