For some reason, the Canon version of the Tokina lens doesn't have an aperture ring and doesn't need the same set-up process. This is the case with all older lens with aperture rings mounted to Nikons. In order for the exposure meter on the camera to meter and control aperture, the lens has to be set to the smallest aperture setting (f/32 here). The Nikon version still has an aperture ring. The Tokina is an old design (2007 vintage). (I haven't looked at the branded Nikon, so I don't know about that.) Apparently, that's not the case for these Sigma and Tokina lenses. What's going on?Īnd one last thing - My Canon 100mm macro comes with a tripod collar. I don't have to mess around with aperture. What in the world does that mean? With my Canon, I just mount the lens, set the lens barrel switch to MF and go. Note: When set on other than the minimum aperture value (f/32), the "FEE" error message flashes and the shutter cannot be released. When setting the aperture value to f/32 and then changing it by the dial on the camera, the aperture value displayed in the viewfinder will be other than f/32.Īt this time, the diaphragm blades do not move but will operate according to the aperture value displayed when shuttering. To prevent accidental movements of the aperture ring from the minimum aperture value the ring can be locked in place with the small slide switch adjacent to the ring (to release the lock, slide the lever to the opposite side). When using with a Nikon DSLR camera or a film camera with CPU system, it is necessary to set the aperture ring to the minimum aperture value (f/32). Tokina AT-X M100 AF PRO D for Nikon mount conforms to the specifications of "Ai AF-D" Nikon lenses. I did see something on the Tokina website that, as a Canon shooter, I totally do not understand: She's currently running a D7200, so autofocus should be no problem. So if you're not sure or you want the benefit of image stabilization, choose the Sigma. The current Sigma 105mm OS should be compatible with all Nikon dSLR's. If she has a D3x00 or D5x00, the Tokina won't allow autofocus operation. Opinions and recommendations would be appreciated.ĭo you know which camera your girlfriend owns? Unfortunately, compatibility in the Nikon system is not as simple as it is with Canon. Given that the genuine Nikon 105mm macro is a budget buster, the choice comes down to the Sigma 105mm or the Tokina 100mm. But, my girlfriend is a Nikon shooter with a birthday approaching. My copy does not disappoint and is very sharp already at f2.5.Dumb Canon user here. The Tokina has a well-deserved reputation for excellent sharpness. From 0.7 m to the minimum focus distance of 0.39 m, it's a further 180° which is great for achieving accurate focus when shooting macro. The focus throw is a quick 90° between infinity and 0.7 m which is nice for quick focusing but not great for fine tuning the accuracy. Of course, once it's fully extended it is a bit unwieldily. The Tokina is heavy but is actually fairly compact and isn't a bad fit for the Sony. The focus ring is wide and rubberized and works pretty smoothly on my copy, but the aperture ring is a little bit loose-feeling. The lens is a dense and hefty chunk of metal and glass that appears to be well put together. Aperture - 8 blades, f2.5 to f4, f4 to f22 in half stops, f22 to f32īuild quality/Handling (Very good/decent).Length - 83 mm (105 mm with adapter, 145mm fully extended).Tokina AT-X Macro 90 f2.5 specs (for FD breech mount): Actually, the lens isn't a true 1:1 macro without the Tokina Macro Extender, which adds quite a bit to the price and size of the lens. It was also nice to finally add a macro lens to my vintage collection and get out there and shoot some bugs and flowers and other small things. After reading this great review of the lens, I decided to pick one up for an upcoming trip around Japan.
