Top 20 Tamron Zoom Telephoto AF 70-300mm f/4.0-5.6 LD Macro Autofocus Lens for Canon EOS Questions & Answers

The most likely cause for this is stripped gears within the lens.This will require complete disassembly to repair and can be done fairly inexpensively. However, it's not really a user serviceable problem and should be done by a qualified service technician.

My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these. I'm semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.

Actually you are doing really well cause the Tamron specifications for that lens is 1.5m translated into real numbers that's 4.92 feet. If you want some serious macro let me suggest the Canon 100mm F2.5 Macro lens it's not all that bad for price unless you get the IS version then it's out of the park well sort of. Most of my macro work is done on a tripod anyway so the IS is a waist for me.

Here is a review on that lens.

Also is you are using the APS size sensor there is a focal factor of 1.6 so the 100mm lens just grew to 180mm and twice as fast as your Tamron. Cheers

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.

Set up focus point using autofocus, then set camera to manual focus before attaching filter, and be careful not to move focusing ring.

First, I'm not a TAMRON Tech. * Check your warranty and call for service. * Ah, Found this on you tube. (VERY Technical!) https://www.youtube.com/watch?v=o9dvQmVAhK0 * Strongly suggest you have this lens serviced. Aloha, ukeboy57

You'll need to send it to a lens repair service. Do not attempt to disassemble the lens yourself; you'll only make the problem worse and may damage the lens beyond repair.

Use the settings that will give you the best exposure / shutter speed / focus

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 ?

This is a bit off the wall, I know, but have you contemplated taking the drastic step of getting the lens mended ?

Go to the tamron site and find the nearest repair centre to you location

all of my Tamron lenses have the serial number on the barrel of the lens right next to the "Made in Japan" label. When the lens is in the camera the MIJ label is on the bottom side. I hope that helps with your lens

Did you switch the AF / MF switch to AF (Auto Focus)? It is on the lens.

Repair manuals can be bought by certified repair centres. Sometimes you get the manuals when you have done the repair course at the firm. Not sure Tamron does so. But they most of the time don't sell these manuals to normal people, to avoid they start opening a lens, because they never will be able to put it together as a working lens, without the tools, like a collimator.

Simple idea? Dont go to F32..just stay at F22 and increase the camera speed one stop. A little test will give you right calibration

No. The LA-DC58K only allows you to use the TC-DC58K teleconverter with your camera. The Tamron 28-200mm lens is intended for use with SLR (single-lens reflex) cameras, not with point&shoot cameras. As far as I know, there aren't any adapters which will allow you to use an SLR lens with the G10. A teleconverter is an add-on accessory that works with an existing lens. The 28-200 is a lens, which is intended to be used as-is. Using it on the G10 would basically require removing the built-in lens on the G10. As that lens can't be removed...

What mount do you have on the Tamron lens? (The built-in mount.) If it has a Nikon mount, you don't need an adapter at all. If it has the Adaptall mount then the adapter should fit onto the back of the lens, then the combo should fit onto your Nikon camera. If the lens has a different mount then nothing you can do will make it fit.Does the adapter fit onto the lens?

If you got a lens with a Nikon mount then you don't need anything else to fit it to a Nikon camera.
