Question about Tamron Cameras

1 Answer

My Tamron 1.4X tele-converter stopped autofocing.

I use this 1.4X on a canon 70-200mm f/4 lens.  It was working fine, and this just stopped allowing me to autofocus.  this occured while on the lens.  One moment everything was fine, then it stopped.  I tried it on another camera, and another lens (also f/4) with the same problems.  I cannot visually see anything wrong with the Tamron.  This is the lesser priced black version (Tamron-F AF Tele-Converter).  1.4X C-AF1 MC4  Made in Japan
Thanks for any help.

Tele convertors on their own do not focus - that is achieved by the lens. Are the lens contacts clean and correctly aligned with those in the camera ?

SOURCE: Pentax MZ-60

The camera does not operate when a lens with the following conditions attached:

1. When a lens, which does not have autofocus function is attached.
2. When an F or FA lens is attached with the aperture ring set other than the A position.
3. F or FA 85mm f/2.8 Soft lens and FA28mm f/2.8 Soft lens cannot be used because these lenses do not have the A position on the lens aperture ring.

SOURCE: Tele converter option for Tamron 28-75mm f2.8

This is a lens for Sony/Minolta cameras. It is not compatible with the Nikon D90. Hence a Teleconverter for Nikon will not work on this lens to mount it to a Nikon D90.

SOURCE: problem with digital concepts teleconverter

The SX1 has an amazing 20X optical zoom. The teleconverter will allow to get pictures if the camera zoom is not fully on 20X. It means that you can't get a full 40X zoom images, but a 30X maybe. I don't why canon has this problem.

You can order the Tamron 2x teleconverter here. Be aware that not all lenses are compatible with teleconverters, and you can actually damage some lenses by trying to use them with a teleconverter.

The adapter will work if it is for the Nikon cameras Be aware you loose two stops and it makes the lens twice as long, so you need lots of light, to shoot at F5.6 (full open) and 1/400 of a second. when zoomed in. Your lens does not have image stabilisation.

User Manual


I checked the Tamron website menu of manuals and one is not listed. This is a pass-thru device, so other than placing it between your lens and camera body, there should be no additional settings. Your camera focus and exposure is thru the lens so the camera should adjust seemlessly. Please tell us what the problem is, what lenses and body you are using.

I have a Tamron 70-300mm Tele-Macro lens that doesn't auto focus. It's like it is locked up. I have tried moving the normal/macro switch and that doesn't move either. Any ideas will be welcome.


If that is the only lens that you have for that camera, it could be the camera that is bad. There is a sensor in the camera that measures the focus and they do wear out.

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 tamron 70-300mm i had a canon 1000d and the lens worked pefectly fine with it but nw i hav purchased canon 550d and when i conect my tamron lens with it , it shows an error 01 please assist me


This is the kind of error which you always risk these days in buying lenses which are not from your camera manufacturer. Error 01 simply means that the camera cannot communicate with the lens. Canon's protocols are not open standards and third party manufacturers have to reverse engineer to produce something which works. As they're working in the dark, they cannot always arrive at a solution which makes all models suit all Canon bodies.

You have two possible solutions:-

Visually inspect the contacts on the lens and the camera body and if they're anything other than clean and bright then use a clean pencil eraser on them. Be very, very, careful not to let any of the rubber crumbs into the lens or the camera body.

If that fails, visit the Tamron website to see whether the lens can be returned to be updated for other bodies. if it can't then sell it and buy a later Tamron model or better still a Canon one. They may cost more, but the results are better and their resale value is much higher.

Some of the long tele's like that have some sort of locking mechanism on the side to prevent lens creep. Look for switches other than your aperature lock and auto focus/manual switch.

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.

Error 99 in my Canon 300D


You're probably right about the lens. Tamron lenses have a flexible circuit that drives the aperture blades. The aperture might need to be cleaned or the flex might be worn out. Either case needs a repair shop to correct.
