Ill be testing the living daylight out of the new tamron 28 75 millimeter, f, 2.8 di3 vxd g2 lens the follow up to their very popular and affordable original fast standard zoom lens for sonys full frame, mirrorless cameras, tamon claim that this g2 version of the lens Comes armed with a number of improvements, but its also a little more expensive than the original at 900 us dollars or 850 pounds here in the uk, id like to say a big. Thank you to tamrons, uk distributor for loaning me, one of the only review copies of the lens that they had for a week for testing purposes, although, as usual, this is a totally independent review. A fast standard, zoom lens with a maximum aperture of f 2.8, is one of the most popular options on any camera system. It provides a flexible compromise between having a workable zoom range and having a wider maximum aperture of f 2.8 useful for shooting in low light or getting noticeably out of focus backgrounds. They are particularly helpful lenses for wedding photography and photojournalism. Well, all kinds of uses. Really this one is designed from the ground up to work with sonys cameras, so in camera, corrections, eye, autofocus and all those other features all worked properly. In my testing its worth, noting, though, that this tamron lens does not feature image stabilization, which is getting more common to see on standard zoom lenses nowadays, that might be an issue for you if your camera does not have image stabilization built in its also worth noting That this lens zoom range starts at 28 millimeter, instead of the more traditional 24 millimeter heres, some video to show the difference.

I shot this bit of video using a different lens. This keeps the lenses size and weight and ultimately price down, but some people will miss having 24 millimeter available on such a lens and if youre, using an aps, c camera, then 28 millimeter really isnt. A wide angle at all anyway, lets look at the build quality. First, the lens is mostly made of plastic, but it feels much higher quality than its predecessor. It feels much more solid and smoother to touch it. Doesnt feel too heavy on your camera, either weighing just over half a kilogram or a little under two pounds. The metallic rear lens mount is surrounded by a weather ceiling, gasket also towards the rear, theres, a usbc port for firmware update, and that is followed by a plastic manual focus ring which turns very smoothly and cooperates with a focus motor very responsively. The lens does exhibit some focus breathing throughout its zoom range, as you can see here, however, its nothing too serious, ive, seen worse than this before the lenss autofocus motor is reasonably fast. Although on my copy of the lens, it was a little unsure of itself focus hunting a little bit occasionally, the focus ring is followed by a focus hold button and then a rubberized zoom ring that turns very smoothly with just a little stickiness. But if you turn the ring quickly, then it feels a little scratchy. The lens is not par focal. By the way, it changes focus a little as you zoom in and out, as i mentioned its currently only for sonys e mount mirrorless cameras, full frame or aps c.

Its filter thread size is 67 millimeters and it comes with a fairly small plastic lens hood. Overall, the lenses build quality is quite lovely and it looks the business too lets take a look at image. Quality now well start by mounting it onto a full frame camera. My 42 megapixel sony, a7r iii in camera. Corrections are turned on for this test at 28. Millimeter and f 2.8 image quality is absolutely fantastic in the middle razor sharp and the corners virtually as sharp. Actually, although just a little color fringing is visible on contrasting edges, impressive performance. Here, though, the lens stays this sharp down to f11, where a little softness begins to creep in due to the effect of diffraction all right lets zoom in about halfway to 45 millimeter again, we see perfect image quality in the middle straight from f 2.8. This time the corners look just a little softer than before, but a good amount of detail is definitely still being captured and any kind of chromatic aberration is gone. Stop down to f4 for a small improvement here, leading to excellent sharpness again, the lens tastes. This sharp down to f11 stop down any darker and the image will get noticeably soft lets. Zoom all the way into 75 millimeter now at f, 2.8 image quality is still excellent, but now its just a nice edge away from being razor sharp. The image corners now are looking noticeably softer, but still not bad stop down to f4 or 5.

6 for small improvements. But the corners will always lag behind the middle just a little at 75 millimeter, but overall the lenss sharpness on full frame is really impressive. Remember fast, standard zoom lenses are some of the most difficult for lens manufacturers to design its considerably sharper also than tamrons original 28. 75 millimeter. F. 2.8 lens. Okay. Well, this lens focal range means it wont, be the first choice of many aps c: camera shooters. After all, as i mentioned, 28 millimeter is not a wide angle to start with on an aps c camera, but just for your interest here are some aps c test results for my little a5100 camera with its 24 megapixel sensor at 28. Millimeter. The lens is razor sharp straight from f 2.8 in the middle and into the corners staying. This sharp down to f 11. zoom in to 45 millimeter and its the same story really razor sharpness in the middle and excellent sharpness in the corners straight from f2.8 and stopping down to f4 brings about just a tiny bit of extra sharpness, nice and finally, at 75 millimeter its virtually the same story, excellent image, quality in the middle straight from f 2.8, and only a little less sharpness in the corners stop down to f4 for excellent sharpness in those corners to make a return. So if you did want to use this lens on an aps c, camera youll be pretty delighted with the results as they are even sharper than those from the full frame.

Camera. Alright lets turn off in camera corrections and take a look at distortion and vignetting on a full frame: camera at 28 millimeter, the lens project, moderate barrel distortion and at f 2.8. We see rather a lot of vignetting right in the corners of the image stop down to f4 or f5.6 for that to begin to clear up zoom in to 32 millimeter and that distortion straightens out at 75 millimeter, it flips into heavy, pin, cushion distortion and again At f 2.8, the corners are quite dark. You need to stop down to f 5.6 for those corners to brighten up. So this is a lens where you really want to keep. Those corrections turned on now lets talk about close, focusing this lenses. Minimum focus distance when zoomed in is 40 centimeters, which gets you nice and close to your subject at f 2.8. Close up image quality when zoomed in is pretty soft, stop down to f4 or f 5.6 though, and it gets much sharper. If you want more dramatic pictures, though, then zoom out to 28 millimeter there, the lenses minimum focus distance is 18 centimeters and close up image. Quality straight from f 2.8 is much sharper so that minimum focus distance really introduces some nice versatility to this lens. Now lets see how well it works against bright lights. Here you can see that at 28 millimeter there really isnt very much flaring and contrast remains very good zoom in and the flaring increases, but its nothing too serious.

Now lets take a look at the quality of this lenses. Bokeh. A weakness of this lenss predecessor was its slightly ugly looking bokeh, particularly when the lens was zoomed in well. This g2 version sees a vast improvement and its autofocus backgrounds, always look lovely and smooth to me and finally, related to bokeh comes longitudinal chromatic aberration at f 2.8. We see somewhat strong color fringing on bokeh highlights here at f4 and f5.6. It goes away quite quickly. Overall, testing out this new tamon lens was a delightful experience. Its consistently high sharpness and beautiful bokeh, as well as its close focus distance, makes it a creative and versatile zoom lens that lets. You capture some beautiful images, its a very nice improvement over its predecessor in a number of different ways and at 900 us dollars its expensive, but still good value for money. So ive no hesitation at all in saying that this one comes highly recommended. I enjoyed making that review its lovely to see lens designers working hard to improve their products, even the more popular ones.
