Can Tamron 2 X converter C-AF 1 BBAR MC-7 mounted with Canon 100-400mm? Tks


As you can read in the Dpreview link the Tamron converter can work perfectly with the Canon cameras. Question is, will AF still work, because you have to multiply the aperture twice. So if your lens has f/1:5,6 that will become f/1:8. Most camera's can't auto focus anymore on F 8

I have a nikon d60... is the tamron 70-300 zoom lens compatible ?


Tamron makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit a Nikon. Assuming the lens has a Nikon mount then yes, it is compatible with the D60. However, the D60 lacks an autofocus motor, relying on the lens to have one. Some Tamron lenses have such a motor, some do not. Such lenses will not autofocus with the D60, but everything else still works, including manual focus.

Error 99 with a Canon 300D (original rebel) and Tamron XR Di II 18 to 200 mm lens. Occurs when lens is zoomed out. Does not happen with other lenses (Canon 18-55 kit, Canon 75-300). Cleaning contacts on...


Welcome to Fixya
Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.

Thank you for using Fixya!

Wil the Tamron AF 80-210mm 1:4.5-5.6 fit on my Nikon D3000 and if so how does it perform?


Assuming the lens has a Nikon mount, it will fit on the D3000. Tamron makes their lenses with a variety of mounts, so that one with a Canon mount, for example, won't fit onto a Nikon body.

This lens lacks an autofocus motor so you'll have to focus manually. Other than that, it will work fine. It's not the sharpest lens available, but it's also not the most expensive.

Since dropping my Tamron 70-200 lense, it continues to work, but the autofocus is just off. The camera will focus on the subject and take the photo, but when reviewing the photograph it is out of focus....


Hum, something doesn't sit right with what you just described. If the camera in focus green dot comes on solid then the camera is saying the image is in focus. Did you just drop the lens or was the camera attached to the lens and the whole assembly hit the ground. Lets back up some more what is it you are trying to focus on, meaning the camera will be confused solid colour, no contrast, glass, water, chrome. Or trying to focus on something to close for the lens optics yes I know you said Macro but even macro but even this lens has a minimum focus distance. Check your specification sheet that came with the lens. Okay another thing and this is a biggy if you are trying to focus on something at F2.8 close in the camera may catch focus but the DOF is so shallow you can't actually see the focus point and everything appears out of focus. Okay another thing, lets say you have this lens mounted on a tripod at a setting of F11 and a shutter speed down into the 1/50 or even a bit slower, your think you are okay because it's on a tripod right, nope just by you tripping the shutter you have moved the camera and the pictures will be blurry under close examination. In this case you need to do one of two things or both. You can use a 2 second shutter delay and or mirror lock up. I use both when available. I've even gone to using an electronic release in some cases. So if the camera in focus light in the lower right corner of the viewfinder comes on solid then the camera has focus. If the lens was off a bit the in focus light wouldn't come on or if it did it would flicker and if it's not got focus the shutter couldn't be released. So sorry I think it's one of the other problems I mentioned. Hope I helped and not confused you to here is a sample picture a center crop of a much larger picture the scene was 3/4 mile away.

It's pretty crisp but the sizing took a bit the original you can count the brick on the building.

What nikon camera will this mount to


Tamron is a third party lens manufacturer and make lenses to fit all popular makes of cameras both film and digital. I'm sure the top two would be Canon and Nikon. So if the lens you have there is a Nikon Mount it will fit Nikon Auto Focus cameras both film and digital

Tamron lens for Xti?


if it is an auto focus lens that works on one eos camera, it should work on almost all of them. the only known exception is that some high end extenders will not fit the eos1dmarkII as it protrudes into the opening too far.
but a good rule is that if it fits without any obstruction issues, it should work. try cleaning contacts on the lens and camera body. if that doesn't fix it, talk to Tamron. you can use it manually, but will not be as easy and you would get less predictable results.

my suggestion is to always go with lens from camera maker.

sounds like there is an issue with the tamron lens. not the camera.
good luck

AF 70-300 causes error 99 in my Canon 300D


This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.
