Ống kính tamron 85mm vc đánh giá năm 2024

Just as a painter instinctively reaches for the right brush, a portrait artist reaches for an 85mm lens. The focal length is ideal for producing a pleasing image with true-to-life facial features in accurate proportion. While a wide-angle lens makes close objects appear larger than they are, and longer telephotos compress and flatten features, the 85mm medium telephoto is just right. Plus the working distance between you and your subject is perfect for making the personal connection that’s often missing when using a zoom.

The Tamron SP 85mm F/1.8 is the world’s first* 85mm fast-aperture lens with image stabilization. Its unique design allows us to include our VC (Vibration Compensation) system—without the lens becoming too large or heavy. What’s more, our SP 85mm F/1.8 delivers edge-to-edge viewfinder brightness for ease of composition and superior low-light performance. The fast aperture of the F/1.8 also offers the perfect balance of subject sharpness and bokeh, that dreamy blur which separates your portrait subject from the background.

Chromatic aberration appears as magenta or green color fringing along edges and contours in images, especially against bright backgrounds. It happens, in part, when the optic fails to focus all colors of light on precisely the same point, and is more conspicuous in cameras with high resolution and high pixel densities. The SP 85mm F/1.8 uses LD (Low Dispersion) and XLD (Extra Low Dispersion) glass elements in the optical design to minimize color fringing and to achieve sharp and clear image quality with high color fidelity. In addition, by thoroughly reducing comatic aberrations (distortion of off-axis point source) and astigmatism, subjects that appear as a distinct point source will be captured as a distinct point source even at the edges and corners of the frame.

The SP 85mm F/1.8 is designed to provide tack-sharpness of the subject for stunning clarity and flawless image quality. At the same time, Tamron’s design philosophy embraces the notion that photographers—particularly portrait photographers—use background blur, bokeh, as a creative element to concentrate emphasis on the subject. Through numerous simulations conducted for wide-ranging blur effects, such as a gentle, melting transition from the focused to the out-of-focus areas, Tamron has created a soft, natural blur effect that achieves perfect harmony with the inescapable sharpness.

The SP 85mm F/1.8 is the world’s first* lens with a fixed focal length of 85mm and a fast aperture of F/1.8 that’s equipped with the VC system. Camera movement—often too minute to be perceptible to the photographer—is the leading cause of unpleasant photographs. In addition, newer DSLR cameras with higher pixel densities are more susceptible to subtle camera shake.

This technology makes it possible to take photographs handheld in dim light and to make optimal use of slower shutter speeds and increased depth-of-field without extreme increase of the camera’s sensor sensitivity (ISO equivalent). This is especially important in portraiture because lighting is often low and the photographer needs the spontaneity of not using a tripod or disruptive flash units.

Areas of possible ingress surrounding switches and the boundary between the focus ring and the lens barrel are protected by special seals. This provides deterrence against the intrusion of water droplets. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

The superior technology inside the Tamron 85mm is matched by advanced external ergonomic features under a design philosophy called “Human Touch.” Improvements include altering the geometric shape and resistance of the AF/MF and VC switches to deliver comfort with secured operational feedback, and enlarging the distance scale window to maximize visibility and legibility. Even the font style has been newly developed to enhance legibility as part of the overall product design.

When Tamron announced their new initiative to make major improvements to their lenses, the quality of the products was rather mixed–and so that made me a bit scared about the new Tamron 85mm f1.8 Di VC USD. But they’ve taken some time, improved things even more and with that said, they’ve created a lens that could arguably be called the absolute best value 85mm lens for DSLR cameras.

The lens features 9 aperture blades, 13 elements in 9 groups, weather sealing, an actual metal barrel, and a very overall light weight of approximately 23 oz to 25 oz. At $749, you’re getting what looking on paper to be one hell of lens.

And in all honesty, I actually want to buy one.

Ergonomics

Before you start, this video shows you how the images were shot.

Consider that Tamron has always been very much about being simple with their lenses and you’ve got some of the understanding behind how they created the 85mm f1.8 Di VC USD. It’s got a slightly textured metal body; though some may want a tad more texture for better grip.

Looking straight down at it, what you’ll see is the distance scale for focusing. Above this you’ll find the rubber focusing ring–which is quite textured for better grip.

Looking at the front of the lens, you’ll find the 67mm front filter thread. Tamron keeps all markings off of here.

Note that without the lens hood, the lens package overall is quite small.

On the side, you’ll find all the controls. Here you can set the lens to manual focus or autofocus and you can also activate the vibration compensation.

Build Quality

This lens is weather sealed; but they’re calling it moisture resistance. You can feel it at certain parts like at the lens mount. Though I didn’t give the lens a whole lot of abuse it was in camera bags being tossed around on the NYC Subway during heavy commutes and it also survived a rainfall.

You can tell that this is one of Tamron’s new SP lenses because it has the brass white ring towards the back.

Here’s the weather sealing diagram; the blue is where sealing is placed.

Autofocus

Jenna Black

The image above was shot with a flash placed into the pizza box and it’s for a personal series that I’m working on. In the very dim 9pm light in Madison Square Park, I was able to still get sharp focusing on Jenna’s face without AF assist. Granted, I needed to use the center focusing point with the Canon 6D–but that camera also doesn’t have the best AF to begin with it in some situations.

The focusing from this lens is just as fast as Canon’s own 85mm f1.8 lens; which is quite a feat for it to be capable of.

Ease of Use

Slap the lens on the camera, point, shoot and enjoy. That’s really how simple it is to use this lens. During my tests, taking the camera and lens in and out of a bag didn’t make the AF and VC switches move at all. That’s just great design in effect!

Image Quality

ALL IMAGES HAVE EXIF DATA IN TACT. CHECK THE FILE NAMES OR CLICK ON THE IMAGE AND FIND IT IN THE URL.

So here’s the section that you’re going to care about the most. For years now, I’ve been a Sigma 85mm f1.4 lens owner. Despite the fact that it’s starting to show it’s age in terms of sharpness when looking very closely, I’m still not at all dissatisfied with it. The lens is highly capable and still helps me create beautiful images in the same way that all the super antiquated Canon glass does but that people still drool over.

For what it’s worth, the Tamron 85mm f1.8 Di VC USD wipes the floor with everyone else’s lenses except for the newest offerings from Zeiss. It doesn’t have micro contrast but instead it has a couple of things that have made me change my editing workflow. I generally don’t need to do anywhere as much of a clarity increase and instead what I tend to do when working with this lens is work with the shadows and the individual color channels.

Bokeh

This is a photo that was shot at pretty much the closest focusing distance. As you can see in not only this image but loads of others in this review, you’ll see that the bokeh is beautiful. It’s about on part with what Sigma can do (though a bit better) and in my opinion isn’t as nice as what Zeiss can do. However, what Tamron and Zeiss do is much different in the way it looks.

Color Fringing

Straight out of the camera, I couldn’t find very much color fringing. However, it came out when I bumped up the contrast a bit in some images when developing in Lightroom. Overall though, it isn’t so terrible to the point where it will bother you when looking at the image as a whole. You’ll only see it when pixel peeping–and to be honest your clients are going to pixel peep your images; so you can relax and stop freaking out.

Color Rendering

The color rendering as it is from the Tamron 85mm tends to be very true to life with a tad of saturation. It doesn’t have as much contrast as Sigma and Zeiss offer out of the camera or as much saturation. But at the same time, the saturation and contrast aren’t exactly what I’d call muted. I’d say that Tamron instead took a little less liberal of an approach here.

Sharpness

The best sharpness from this lens comes when using a flash with the lens stopped down between f5.6 and f11. The best balance of bokeh and sharpness comes at f4. For the most part though, I almost had very little reasons to stop down below f8.

It’s sharper than the Rokinon and Sigma 85mm offerings; but not sharper than what Zeiss offers.

Conclusions

Likes

• Build quality
• Fantastic overall image quality that is very unique in some ways
• Fast autofocus
• Weather sealing
• Fairly affordable for what you’re getting.

Dislikes

• A bit more texture on the metal body might be nicer for grips; but even so it isn’t that terrible.

The Tamron 85mm f1.8 Di VC USD is very, very great. It’s under $1,000 and you get a load of awesome things in this small package. This lens has sharp image quality, fast autofocusing, great bokeh, a unique look to its contrast and saturation and best of all you’ll get weather sealing. It’s lightweight and can do well in the hands of amateurs, enthusiasts, semi-professionals and professionals alike.

To wit, it will also do very well on high megapixel camera bodies. Though on that thought process, it just makes sense to move up to Zeiss at that point.

The Tamron 85mm f1.8 Di VC USD receives the Phoblographer’s Editor’s Choice award and 5 out of 5 stars. Want one? They’re available for $749 on Amazon.
