7 di3 vc vxd. It is for full frame cameras and it’s, also tamron’s. First long, telephoto, zoom lens specifically designed for mirrorless cameras. Its unique features are its impressively small size for a 500 millimeter lens enabling it to fit into your camera bag quite easily, as well as fast autofocus and an ability to shoot very closely to your subject. Oh and it’s supposed to be very sharp too well we’ll, be the judge of that in a minute. Its zoom range is long telephoto, all the way and its maximum aperture of f5 at the wide angle, end and f6.7, as you zoom in, is pretty dark, although that does contribute to the lenses more compact size. It is only for sony’s mirrorless e mount cameras. Its cost of fourteen hundred dollars in the us or thirteen hundred pounds in the uk is certainly pricey for a lens with a relatively dark maximum aperture let’s hope the quality is there, because this is not a budget lens option i’d, like to thank tamron’s uk distributor For loaning me this lens for testing for a couple of weeks, although, as usual, this is a totally independent review, as i’ve mentioned, it’s, surprisingly small for a lens of this kind, feeling more like a 400 millimeter lens, although it does feel a little heavy, weighing 1.7 Kilograms or just under 4 pounds it’s based on a metal lens mount with a weather ceiling, gasket and the rest of the body is made of plastic but feels very solid and tightly assembled.

It comes with a strong metallic tripod collar, which is easily adjustable and removable towards the rear comes a plastic focus ring. It turns averagely smoothly and works responsively with the focus motor and, as you can see here, there’s almost no discernible focus breathing for autofocus. The lens uses tamron’s vxd system or voice coil extreme torque drive, as you can see here, it works nice and quickly, confidently and accurately, without making any noise, which is great. The lens zoom ring is large and rubberized turning evenly and slightly stiffly. It can be locked at 150 millimeter for transport, or you can simply push the ring forward to lock it into any position. The lens features its own image, stabilization, which tamron always call vc. Here is some footage with it turned off and now turned on. As you can see, it works averagely well, but i have seen a better. It has a panning mode and a framing mode, neither of which seem to make much difference when shooting video the lens comes with a good quality plastic hood and its filter size is 82 millimeters. The front edge of the lens has a rubber seal for extra protection. In case you bump it into something overall, the lens has really rugged, build, quality, feeling tough and a little heavy, and while its image stabilization is not spectacular, its autofocus is very good now onto image quality i’ll start by testing it on a full frame camera. My 42 megapixel sony, a7r iii in camera, corrections are turned on at 150, millimeter and f5.

The lens is very sharp in the middle, with very good contrast. Although you can get a bit sharper than this over in the corners, the image is softer, but still not bad stop down to f8 and those corners sharpen up and image quality back in the middle is razor. Sharp now f11 looks just as good in the middle, but over in the corners we see another improvement in sharpness there at f16. The lens is beginning to get a bit softer due to the effect of diffraction let’s zoom in to 300 millimeter. Now the maximum aperture is f, 5.6 and in the middle of the image, sharpness is just good again. The corners are just a little softer at f 8. They get slightly sharper and the middle is very sharp. Now like at 150. Millimeter f11 is just as sharp in the middle, but the corners get a little better. Now, let’s zoom all the way into 500 millimeter. The maximum aperture has really darkened now down to f 6.7. The lens shows its impressive consistency by remaining quite sharp in the middle, with good contrast, corner image. Quality is a little sharper than it was at wider angles, though. Looking pretty good straight from the maximum aperture f8 looks about the same, but at f11 back in the middle. We see excellent resolution now so overall on a full frame camera. The tamron lens offers good contrast and consistently good, but not truly excellent, sharpness, it’s, a pretty good performance, and certainly anyone with a 24 megapixel camera will be delighted.

If you own a sony a7r4, though don’t expect to get 61 megapixel images out of it. The 42 megapixel center of my sony, a7r iii, is really pushing the limit of its capabilities. Well, let’s see how it performs on an aps c camera now here it is on my 24 megapixel sony, a5100 at 150, millimeter and f5. The picture is nice and sharp in the middle, but the corners do look a little softer. The image stays this sharp down to f11, where a little softness begins to creep in due to the effects of diffraction on a smaller aps c sensor, let’s zoom in to 300 millimeter and it’s. Basically, the same story here quite sharp in the middle and a bit softer in the corners and stopping down the lens to f8 or f11 brings some minuscule improvements and again at 500 millimeter. It really is the same story sharp in the middle at the maximum aperture and softer in the corners f. 8 looks about the same, but f 11 is a bit sharper in the corners. So generally, it is a boringly consistent performance here, but that is no bad thing on an aps c camera the lens is always sharp in the middle and the corners always need just a little stopping down for best results. All right, let’s see about distortion and vignetting on a full frame camera. These pictures are taken with, in camera, corrections turned off again it’s, another incredibly consistent performance, there’s, some pincushion distortion throughout the zoom range from 150 to 500 millimeter and at the brightest apertures the corners will always be noticeably dark, stop down to f8 and the corners will Brighten up again, so you should keep in camera.

Corrections turned on with this lens now onto close up image quality, whether you’re zoomed in or out. This lens can get you fantastically close to smaller subject, but zoom out to 150 millimeter for a slightly closer distance. So at 150, millimeter and f5, the close up image quality is excellent, although some purple fringing is visible on contrasting edges, stop down to f8 and that fringing goes away, let’s see how this lens works against bright lights. Now. The good news here is that flaring is not really a problem with this lens, whether you’re zoomed out or zoomed in. It maintains your contrast very well and finally bokker when it comes to autofocus backgrounds. There are no real issues here. Even difficult backgrounds are rendered quite nicely, as you can see, so i had a good time testing this new tamron lens it’s, relatively compact, considering its zoom range, its autofocus and image quality are all good and its close shooting capability is really enjoyable too. I think tamron are asking a bit too much money for it here. The lenses performance is consistently very good, but perhaps not quite fourteen hundred dollars. Good and its marketplace is getting increasingly crowded still for anyone looking for a nicely handling lens in the smallest size possible. With a good long reach, i can recommend it that’s it for now. I hope you found this review helpful. If ever you thought to yourself boy chris, just doesn’t put out enough content for me.
