Question about Tamron 70-300mm f/4-5.6 Di Zoom Lens for Canon AF Cameras

1 Answer

Lens will not change range. Something came loose inside

The lens is in perfect shape, I used it for about 6 months and then the zoom would not adjust with the turn of the barrel. I have had no luck finding a repair manual. Anyone know of one or an illistrated parts breakdown. Cheaper to buy a new one that have Tamron fix.

Thanks

I bought Canon EF 75-300mm III Zoom Lens, but the len is very loose, is it problem


Long and short of it...if the photos are close to "decent", dont worry bout it :) It aint no L Lens but can still throw out a good pic every now n then. Tip it from one end to the other whilst holding it...if you hear something go \'ring-a-chicka-chink-chink-clunk\', then youve got problems, otherwise grin and bear the looseness - mine lasted 6 years of hard yacker before i dropped it in the drink!

Lens unable to auto focus


try cleaning the lens.

Also set the focus range in the camera to average both vertically and horizontally. That is when you press the shutter button thos red squares in the look through a;; ;light up rather than just the centre square.

I suspect it is getting feedback from something on the lens that it reads and tries to focus on that is closer than the object you want to photograph. Make sure there is no mold growth inside lens as that will do it too

I need a manual for AF 35-70mm f2.8 D zoom nikkor - no idea how to use this lens.


i was not able to find a manual - this review may help http://www.kenrockwell.com/nikon/3570.htm
The lens consists of
  1. Zoom
  2. Focus
  3. Aperture
  4. Macro
1) Zoom - this is by push pull - so you push the lens out to wide angle 2) To switch to manual focus - will need to be done on the camera and then you can use the front control ring to focus - 4) also you can use the button to switch to macro mode - BUT only with the Zoom at 35mm - lens fully extended 3) You have an aperture range of 2.8 - 22 this varies the amount of light allowed into the lens - 2.8 is the most light - F4 to F5.6 to F8 - each change halfs the light allowed in - so changing from F4 to F5.6 half the light

What magnification is a 75-300mm lens (10_20_30 times ???)


This lens has a zoom ratio of 4 :1 or 4 times.

Basically 75mm x 2 = 150mm
150mm x 2 = 300mm
I hope that helps,

There is a small black tube like piece that has come loose inside my lense and I need instructions on how to disassemble. It has something to do with the zoom I think?? Nikkor 18-55 ED


The small black tube piece is a sliding light baffle which has come loose. Zoom lenses are very complicated to disassemble, and you have to have both the knowledge, experience, and the right tools to disassemble a zoom lens.

The tube should never have come loose in the first place, so I would classify this as a product defect. Contact Nikon, fully describe the problem, and insist that they repair the lens at no charge (although you will have to pay to ship the lens to their repair center).

70-300 DL Sigma Macro Zoom lens element loosened, and then reset


amaizin, That's not really normal, because you might only normally hear a tiny noise if you shake a lens not mounted on the camera, but not loose glass sound, everything is fixed and solidly set for alignment when focusing if any element is loose it could never be able to get a clear focus and the element would be so scratched there would be all kinds of distortions even if it went "back into" place. You'll hear loose glass after you drop a lens on to the sidewalk or hard surface and an element is dislodged. Inspect the lens body for an impact mark a lightened portion in a ring shape where the metal or plastic has been stressed or the telltale signs of an abrasion from something like a hard rough surface such as concrete (a little group of pin **** on a corner). The lens should be inspected by a reputable shop to determine if it needs to be repaired or replaced. I take it that you were selling it to upgrade to another lens or other equipment. randy320sgi

Cant adjust below f/5.6 on a eos 40d


You are correct in thinking that it should be possible to set the aperture wider than f/5.6 at the wide end of the zoom range.  My best guess is that the lens is defective.  I'd suggest returning it for a replacement.

Quantaray 28-200mm Aspherical IF


If I read this right, your lens is a 28 to 200mm zoom lens with aperture of f:3.5 - f:5.6. What this means is that at 28mm it has a maximum aperture of f:3.5. When you zoom out to 200mm, the maximum aperture is now f:5.6. This is perfectly normal for a zoom lens of this type.

Typical situation in Shutter preferred mode. I have the shutter set at 1/125 of a second and the f:stop is f:3.5. When I zoom out to 200mm, the shutter speed is still 1/125 of a second, but the f:stop is now f:5.6 and I have decreased exposure (darkened the picture) by almost 2 full f: stops.

Realizing this, I think that "turning off the camera" really isn't a fix. The problem is realizing that the aperture will change as the focal length of the lens changes (as you ZOOM in or out on your subject). Try the aperture preferred mode and you should note that the shutter speed will change as you zoom in and out.

Most important, pay attention to shutter and f:stop info in your viewfinder. FYI : Zoom lenses that hold aperture at all ranges cost several thousand dollars, and canon makes them - they weigh a ton.
