Tokina AT-X M35 Pro DX 35mm F/2.8 - The Sturdy Lens

A lens acts as the eye for your camera determining how your camera ߵseesߴ the subject and how that information is transmitted to the cameraߴs sensor. This can greatly enhance your efforts to capture great moments. However if you are going to purchase one, you need to be sure if it is compatible with your digital camera. The Tokina AT-X M35 Pro DX 35 mm F/2.8 is designed for Digital cameras with APS-C sized CMOS and CCD sensors, those with Full Frame sensors. Itߴs quite similar to the Pentax SMC DA 35 mm F/2.8. Despite having a short focal length, these lenses are meant for macro photography. It has a reproduction scale of 1:1 with a minimum focusing distance of 14 centimeters. This makes it appropriate for shooting stationary objects. It has a small APS-C/DX sensor, which makes it almost equivalent to a classic 50mm lens.

The lens has a maximum and minimum aperture of f/2.8 and f/22 respectively and has no aperture blades. Its optical construction places nine elements in eight groups. The front element of the AT-X M35 PRO DX lens has a “Water Repellent" optical coating on the glass which makes cleaning of marks such as spots left by water or finger-prints much easier to clean than standard multi-coating. However, the lens itself is not water proof or water resistant.

The lens weighs about 340g and measures about 60.4 mm in length and 73.2mm in width. This makes it a bit big and heavy when compared to other similar lenses. This is due to its sturdy build of solid metal and a metal mount. The big and comfortable manual operated focus ring is also a contributing factor. This lens is designed to shoot at life size. It is equipped with a group of lenses placed in a narrow tube, which extends to reach the minimum working distance, pushing the overall dimensions of the lens to 9 centimeters. All these factors are instrumental in determining the size of the lens.

So far, I have experienced only one problem with this lens. Switching from auto focus to manual focus mode is achieved by moving the focus ring all the way to the mount of the lens. This makes the ring rotate in auto focus mode. The auto focus mode has presets that cannot be adjusted manually therefore, some scenes have to be taken using manual focus reducing the degree of sharpness created by auto focus. This feature however eliminates the need to change the AF-MF switch on Nikon cameras. The lens does not auto focus when used on Nikon D40 SLR body.
