Tokina Atx-I 100mm F2.8 FF Macro Lens Nikon Mount

Lo primero es decir que hay un error en el nombre que aparece en la descripción del producto. Dice "Canon EF", pero este modelo en particular tiene montura para Nikon F. (Claro que también existe para Canon, pero no es éste) Es un objetivo de gran calidad con una nitidez brutal, por la mitad de precio que algo similar de Nikon o Canon. Excelente reproducción de color y prácticamente nulas aberraciones. Muy buena construcción. El autofoco es rápido y el enfoque manual es suave y preciso. Además de para macro, también sirve como teleobjetivo de uso general y para retrato (aunque produce un bokeh un poco nervioso, pero es de esperar). Execelente relación calidad-precio.

Ottimo qualità elevata consiglio ha tutti.

This review is more of a general heads up for those looking into a first "real" macro lens. They work a little differently than most of your other lenses because they get much higher magnification than other lenses. Basically, this is my attempt at a physics lesson that doesn't hurt. So, here goes. A common complaint with nearly all macro lenses capable of 1:1 or greater magnification that also focus to infinity is that they, "won't change the aperture to the f-stop on the box", and as you get closer to the maximum magnification, the closest the lens will focus, the aperture number gets even further away from the one on the box. Sorry, this explanation will be a bit long, so if you don't want to read all the way down the simple answer is: "This is working the way it should and is not broken, and is not a trick by Tokina. All macro lenses do this when magnification increases. It's the laws of physics. Relax and let it happen". The whole explanation is this. All macro lenses listed with a maximum aperture will operate at that maximum aperture from infinity focus to approximately 1:10 magnification (1/10th size projected onto the sensor). This should start happening just further away than arms length on longer lenses, and closer on wider angle macro lenses. It is around this point that the macro compensation for aperture will start telling your camera that the aperture maximum is less than printed on the body. This is because the lens is physically extending away from the sensor, like a built in macro tube / bellows, and causes the light to travel further to hit the sensor. Because it has to travel further it becoames dimmer (inverse square law - look it up on the internet). The further out the lense goes the higher the magnification and the dimmer the image. The physical aperture is still the same f/2.8 (or whatever your macro lense lists), but, to pass the camera body the correct compensation for exposure the sensors in the lens will start reporting smaller and smaller apertures, like f/3 or f/4.5, and up to f/5.6 or smaller on some macro lenses. This is to make your life easier so you don't have to mess with magnification compensation tables like we used to have to in the pre-computerized photography days. So, yes, the reported aperture of the lens will always be a smaller aperture as you focus closer and closer until reaching the maximum magnification of the lens. This is the correct behavior of the lens. This is what you want the lens to do automatically. All the macro lenses capable of near life size to larger than life do it. Enjoy the lens and don't let this worry you. It's a fantastic piece of glass and engneering! (get a tripod and cable release for sharpest images, really!) Good shooting, and, thank you for hanging in with me during this lesson in the physics of light! It's amazing stuff! :)

OK, so first of all... this is a great lens! - Very good image quality (Very sharp / Nice colors) - Very good build quality - Nice "touch and feel" But... - One-Touch Focus Clutch Mechanism is a bit "odd" - It doesntt have image stabilization - For the price, you may want to consider other options Verdict: While I like the image quality, sharpness and color reproduction of the Tokina lens (and think that the price is "fair" for what you get), I would nevertheless consider the following alternatives and compare before buying: - Laowa 100mm (like the Tokina, it doesn't have image stabilization... BUT it allows magnification up to 2:1) which is quite handy! I own this lense as well and while the image quality of the Tokina lens may be slightly better the 2:1 factor adds some nice creative possibilities. Both lenses are great, for different uses! - Tamron SP AF 90mm (like the Tokina it only allows 1:1 reproduction... BUT it has image stabilization - and apparently the image quality is good too). I cannot judge about this lens because I have never used it but critics are pretty positive and I have seen some nice sample images.

Really superb lens. Light weight with a good built quality. You can we very sharp pics. Focussing is little slow. Good for both macro and portraits. Worth buying.
