Lens parameters:

Compared with the previous generation, the mirror body is longer in length and less in appearance than the previous generation, and basically the front and back diameters are relatively close. The width of the focusing ring of the new design is increased, and the damping feeling maintains the comfort of the red circle lens, , Feel and handling is very good.

Canon EF 85mm f / 1.4L IS USM lens diameter of 77mm, 72mm larger than the previous generation, which is also because the shape becomes more straight tube, the heaviest part of the previous generation diameter larger than this, but the diameter of the filter aperture contraction 77mm caliber filter with more convenient, of course, the filter price is more expensive.

Canon EF 85mm f / 1.4L IS USM lens with a waterproof drop dust structure, the lens mount, the focus ring and the switch, etc. were sealed, which can effectively reduce the dust and other invasive body, thereby enhancing the reliability of the lens Sex, but also to meet the needs of professional photographers shooting in harsh environments.

Lens before and after the lens used ASC antifouling fluoride coating, which can effectively inhibit the ghosting and glare caused by light reflection, not easy to attach dust and stains and easy to wipe.Of course, such a expensive lens, usually or with a protective mirror is better.

Because joined the anti-shake function, the fixed focus lens on a single lever, now also added a shake lever, anti-shake compensation effect of about 4 shutter speed, because the focus is close-up use, anti-shake is no different Mode setting.

Canon EF 85mm f / 1.4L IS USM lens with focal length ruler window, the closest focusing distance of 0.85m, with full-time manual function, you can manually fine-tuning in autofocus mode.

Lens tail bayonet has a circle of rubber seals, two lenses before and after the lens is fixed, there is the use of the inner focus of the design, this fully enclosed mirror body, to avoid gray mold into question.

Canon EF 85mm f / 1.4L IS USM lens hood with a new family design style, the same plastic material, the outer surface of the sandblasting, anti-glare inside the design, to prevent reflection of the inner wall, but inside the front of the hood The flocking design, the new hood is replaced by thread wall, the texture is relatively weak.New shade support lock button, can effectively prevent accidental release.

In simple terms, Canon EF 85mm f / 1.4L IS USM and 5D Mark IV fuselage with a coordinated, no top-heavy feeling. With anti-shake and USM focus module can be controlled in this size, very rare, of course, the price Naturally high-end price. The new generation of Canon EF 85mm f / 1.4L IS USM fixed focus portrait lens, the aperture full resolution is sharp? The test machine for the Canon 5D Mark IV, off all the machine optimization, the use of tripod , Turn off the anti-shake, shooting the highest resolution JPG format, from a different aperture center edge sharpness, purple edge dispersion, vignetting and background blur effect to test the lens quality.

Second, the Canon EF 85mm f / 1.4L IS USM lens sharpness evaluation

Test the resolution of the Canon EF 85mm f / 1.4L IS USM with outdoor real-world shooting, the center of the cut and the edges. The test results are as follows:

The center position, in the case of full aperture, the picture quality sharpness performed well, the maximum aperture sharpness is quite good, with the aperture contraction, the lens sharpness to further enhance the peak at the f / 4 state, at f / 11 began to appear after the sharpness and sharpness reduction edge position, the same as the center position, f / 1.4 has a very good sharpness performance, f / 2.8 and image quality and sharpness to achieve the best performance , Until f / 11, picture quality and sharpness decreased significantly, this is inevitable.

In general, with the anti-shake technology, fixed-focus lens can use such a high quality imaging quality is indeed quite outstanding, even at the f / 22 minimum aperture, the edge of the picture quality is good, can have high resolution Thanks to its best antifouling fluorine coating and its superior optical technology, this new, high-pixel body like the Canon 5D Mark IV and Canon 5DS R Canon EF 85mm f / 1.4L IS USM lens can highlight the high sharpness of high-pixel performance advantages.

Third, the Canon EF 85mm f / 1.4L IS USM lens purple edge evaluation

As we all know, the large aperture in high contrast environment, highlight the location is very prone to purple fringe dispersion phenomenon.New generation of Canon EF 85mm f / 1.4L IS USM fixed focus portrait lens, purple fringing performance will be like? By shooting Strong sunlight under the metal shell, and interception of high light areas, the test results are as follows:

From the aperture of the screenshot view, the Canon EF 85mm f / 1.4L IS USM lens purple suppression control is very good, in the large aperture lens has been very rare, especially compared with the previous generation of products. The maximum aperture f / 1.4 under the purple edge still exists, but it has been very slight.Aperture contraction to f / 2.8, the dispersion significantly improved, shrink to f / 8.0, the dispersion disappears completely.In fact, the basic body and repair software Dispersion can be eliminated, large-aperture lens in the high contrast environment to bring the dispersion problem completely do not worry, so this lens high contrast shooting can be said to be assured.

Fourth, Canon EF 85mm f / 1.4L IS USM lens vignetting distortion assessment

Canon EF 85mm f / 1.4L IS USM lens vignetting distortion Evaluation
f/1.4	f/2.0
f/2.8	f/4.0
f/5.6	f/8.0
f/11	f/16
	-
f/22

Generally speaking, the distortion of the telephoto fixed focus lens will not be serious problems, Canon EF 85mm f / 1.4L IS USM lens in the case of the overall optimization of the body, there is a slight pincushion distortion, but does not affect the actual use , The fuselage is optimized to open can be amended.While vignetting.About the optimization of the fuselage in the case, we can see that the Canon EF 85mm f / 1.4L IS USM lens at f / 1.4 is still very obvious, Shrink to f / 4 after completely disappear.Open the fuselage optimization can be amended.In fact, in the digital age, vignetting distortion can be through the body optimization and post-processing to solve, we do not have to worry about these problems.Another point is, In portraits, a particular scene to add a little dark corner will make the portrait more prominent, more flavor.

Fifth, Canon EF 85mm f / 1.4L IS USM lens bokeh effect evaluation

For a fixed-focus portrait lens, the issue of coke imaging is also very noteworthy, the new generation of Canon EF 85mm f / 1.4L IS USM fixed focus portrait lens, the appearance of the coke? By shooting test The result is as follows:

Canon EF 85mm f / 1.4L IS USM lens vignetting distortion Evaluation
f/1.4	f/2.0
f/2.8	f/4.0
f/5.6	f/8.0
f/11	f/16
	-
f/22

From the real proofs can be seen in the f / 1.4 maximum aperture blur effect, can be said to be very beautiful, because the Canon EF 85mm f / 1.4L IS USM built-9 circular aperture blades, and f / 4 The blurring effect is still to force the performance of the new lens is still very outstanding natural soft coke, the transition can be said to be very comfortable, you can prove the high level of lens grinding.Overall, this is a can not be the future Less like a new choice for photographers.
