TOKINA ATX-i 100mm Macro F2.8 for Nikon F Mount

Gran calidad

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!:)

Tengo una Nikon D7500 y este lente le funciona muy bien , excelente para fotografías macro

Having had the lens for only 48 hours and shot about 100 images I think it's safe to say this is a very sharp lens. The image is uncropped, unedited shot hand held in very light breeze with Nikon D500, f25, 1/1000, ISO 3200.Pros- light weight so it will be in the backpack all the time; auto focus/manual focus clutch is fast to activate and easy to use, compact size; focus index is clear and easy to read; good build quality; focus ring movement is smooth and not to fast or too slow to move elements.Cons- will not work with D5X00 or D3X00 cameras due to lack of camera internal motor; no pouch for when it is not on the camera. (I know, waaaaaa)Like I said, I've only had it for 48 hours but I'm impressed with the build quality and images. Manual focus is easy as the ring has a smooth throw...roughly 245 degrees from infinity to 0.3 M (11.75 inches).For $350 I think you would be hard pressed to find a better value.

I love this lens. It’s great for clinical photography at a good price. I highly recommend it if you are a health professional student in need of a macro lens.The price to performance is great. I couldn’t afford a more expensive macro lens. And having compared it with friends that have more expensive lens, there are minimal differences.I love how smooth the manual focus adjustment is. I love that you can manually adjust the aperture. All in all. Fabulous lens.Just note that the AF does not work with adapters for mirrorless Nikon cameras. Or at least the one that I have.

I wanted a good macro lens to help take better photos of insects, flowers, etc. at closer range. Took it out today for a couple of hours at a nature sanctuary and had great success. Taking pictures of small bugs on leaves can be quite challenging, but I'm very happy with the quality of the photos with this lens..

Exceeding quality picture

Didn’t like the quality, so I returned it 6 weeks ago. I am still waiting for my refund! What a poor service!
