20 Most Recent Tamron 28-75 F2.8 XR AF Lens Questions & Answers


This lens is probably ruined anyway, before you began your DIY attempts. Take it to a repair facility, but be prepared for a hefty bill, even if they will countenance attempting to repair it.

A Canon EF mount film lens will work on a digital camera. What you need to know is what you want to capture, subject, distance, field of view you are wanting to provide. Without that knowledge nobody can provide you an appropriate answer.

it should have some problem in your aperture model.

You didn't state whether you are using it on an APS-C or a full-frame SLR, but that lens is known to be very soft and unsharp especially at the edges until you stop it down below f4. It also exhibits strong vignetting until you stop it down.

The effects are far more noticeable when using a full frame sensor.

Some production examples will be worse than others, and some users will notice the unsharpness more than others. You clearly find the performance to be unacceptable, but it is mentioned in almost every review of that lens. Your lens is not unique in the weaknesses it exhibits as most lenses perform worst at wide open apertures.

You have discovered one major reason why some lenses are cheaper than others, and why lenses designed especially for low lighting levels are hugely expensive..

Your only real fix is to try and avoid shooting at apertures of f4 and larger. If that's unacceptable to you and you need a lens which performs well in low lighting conditions then you can only return the lens for a refund (much easier if you live in the UK due to the Sale of Goods Act). If you cannot get a refund then I suggest you sell the lens and buy a better quality replacement, or better still replace the zoom lens with fixed focal length prime lenses.

Zoom lenses are always an optical compromise, particularly so with zooms covering the wide to short telephoto range, and now that many dSLR's can produce low noise results at very high ISO settings there's less demand from customers for manufacturers to make lenses which have outstanding performance at wide apertures at higher cost.

I Have a problem qith the Tamron 28-75Aspherical Lens XR Di for Canon mount. Just make a strange sound like to power on the iris motor when you insert the lens to the camera body. I just disarmed totally it, but the problmes seems to be with the electronics parts.

If you are interested I will sell the lens to you or you can sell your broken lens to me. For contact please write to partgio @ hotmail . com or to partgio @ yahoo. com or partgio @ gmail.com

Thanks in advance, all the best

Hi,

You should turn the aperture ring on the lens toits smallest setting (largest f/number). If the ring has a lock, lock it inplace. You control the aperture from the camera body, just as you would on alens with no aperture ring.

Let me know if you need more information


Thanks
