SOURCE: tamron 28-300mm lens disassembly help

Both, But start at the rear to remove the electronics and the outer barrels. Remove any rubber grip to expose 'hidden screws'. I would mark everything or document with pictures during disassembly.

SOURCE: I need a manual for Tamron Camera Lens 28-200/3.8-5.6

You didn't supply what kind of Tamron lens it is. I'm gonna go ahead and give it my best shot on a guess: Tamron 28-75mm f/2.8 XR Di LD Aspherical (IF).
If I'm correct, you can download the manual here: http://www.tamron.com/assets/pdfs/A09.pdf
Hope this helps!

SOURCE: Tamron 200-500mm lens on Canon 40D ... when I put

Try gently cleaning the electronic contacts on the lens's mount with an eraser. This will remove any mild oxidation on the contacts. If this doesn't resolve the problem, then contact Tamron and ask if there are any issues using this particular lens with a Canon 40D.

SOURCE: dirt inside back lens element

The dirt has gotten onto the front element of the rear lens group. You do not want to try partially disassembling the lens to clean it. Either Tamron or a good camera lens repair technician should be able to perform what is called a partial internal CLA (cleaning, lubrication and adjustment) of just rear portions of the lens for fairly cheap. Alternatively you may be able to pick up a used Tamron 28-200 in excellent condition for less than the repair cost of your current lens. If successful, then you could turn around and sell your 28-200 for parts or sell it to someone who knows how to service it.

Tamron AF 18-200MM XR Di II LD dust inside; how do I clean?


Dust and other small debris is drawn into the lens due to the vacuum created when zooming in. You can reduce the chances of drawing in dust and debris by slowly zooming in as opposed to rapidly zooming in.

Now that you how it gets in and how to help prevent it from getting in again, comes the bad news. There's really no way to disassemble the lens to clean it up at home. These are precision optics with many small moving parts that really need to be serviced in a dust free environment. You best bet it to contact Tamron (or authorized servicer) to learn how much it will cost to be cleaned by them. This will keep the warranty (if any) intact, too.

Good luck!

Test chart tamrom


Front and back focus tests are good to run. You need to do it for each prime lens (fixed focal length) you have, and at your favorite focal lengths for wide angle zoom lenses too. That means on this 17-50, you would pick wide 17mm and zoomed in 50mm, and several others between. If you pick 25mm and 35mm to test, you would end up with 4 potentially different adjustments. These would apply only at 17, 25, 35 & 50mm. If you shoot at say 20mm focal length, and assume it's the same as 17 or even 25mm, you may be wrong. Too much back or forward focusing is a problem with the camera body usually - not the lens.

I'd pay attention to the lens. Look for cloudiness on the edges of the glass, scratches and fungus on glass, wetness or oil on the aperture blades, specs of dust inside the lens, etc. All of these things take away value from the lens, as they can adversely affect the image or shorten the useful life of the lens. You check these things by looking directly through the lens (not on the camera) and look at a dark background - then a light colored background to help show dirt and dust inside.

The only other thing is to look at actual images taken with the lens. Enlarge the pictures to 100% or more. Look for fuzzy edges, purple fringe edges, colors. You will see all of these issues the more you zoom in. You have to decide what it acceptable to you and what is not. Expensive lenses capture great color, are very sharp and have minimal purple fringing on hard edges (high contrast areas) in pictures.

Good luck!

I have dust particles inside my Tamron 17-55 LD XR DiII SP Nikon mount lens. Is there an easy way to remove them?


No. There is no easy way to remove them, to do so requires an expensive strip down and overhaul in a clean dust-free environment.

Unless you have the dust equivalent of boulders in there, then they are highly unlikely to show on your images and you can ignore them. Even if they do show occasionally you can usually easily correct the faults using commonly available processing software.

What should i do?...my tamron 17-50 began to have a fungus.


Well, that's a great lens and most definitely worth the cleaning/service. I don't know where in the world you are but fungus growing inside a lens is only heard of in high humidity environments and can happen fairly quickly. Are you sure this is a fungus on the inside and not just a clouded smear on the front element? If the lens is having a problem then the camera won't be to far behind. To answer your question more directly "what should I do" my suggestion is to send the lens to a authorized Tamron service/repair center/depot for cleaning. After which get a few of those little moisture absorbing packets and place them in with your photo gear to help reduce the moisture.

Zoom does not work since I dropped my lens


not worth the effort - these are very complicated internal workings and even if you managed to disassemble the glass it would be difficult to know what is damaged without a 1:1 drawing of the internals of that specific piece of glass - plus you do not have a clean room - not trying to comment on your housekeeping but a dedicated clean room with a laminar flow work bench to keep out the FM you would add just by opening up said glass in a normal room - Pay the money if you love the glass - if not they make interesting and fun paperweights...

Clean dust inside the lenz


Don't. Unless there are some really big specks of dirt inside the lens then they will have no effect at all on picture taking. To prevent the problem getting worse always store your lens with it's front and rear caps on and inside a lens bag. Also make sure that your camera bag is clean and isn't shedding fibres from the inner linings.

Dismantling your lens to clean it is really a job best left to a professional who will then additionally check and clean/lubricate the moving parts inside the lens.

I broke the top lens on my Tamron AF 70-200mm f/2.8 Di LD IF Macro Lens. I dropped it. Does anyone know how to order just the lens? I can replace it myself. Everything else on the lens is fine.


Contact Tamron USA via their web site or a phone call to get a price quote for the front lens assembly. However, I would strongly suggest that instead you allow Tamron to repair your lens since more than likely the internal roller glides have been compressed due to the impact. This would allow the front lens group to wobble a bit while focusing and zooming, and this would seriously affect the image quality.
