Is Tamron planning on offering lenses for the Olympus four thirds system in future?
At the moment TAMRON has no lenses with an Olympus bayonet in their current line of lenses. Up to now there are no plans in this direction. Nevertheless, you can be assured that Tamron observes the market very carefully.
I lost the cap or lens hood. Can I order these accessories from Tamron?
Unfortunately, no. As a wholesaler we cannot supply end consumers directly. Accessories can be ordered from a retailer. The item numbers of these accessories are included in the product description of the respective lens on the website.
Can I use a tele-converter together with my 28-300mm?
Tele-converters in general, including Tamron brand converters, are mainly intended for use with fixed focal length lenses and lenses that have a fast f value, such as our AF 90 mm f/2.8 (model 272E) and AF 180 mm f/3.5 (model B01).
If additional lens elements are introduced into an optical system, as done with the use of a tele-converter, the image quality of the whole system is negatively affected. Less light enters the lens when using a tele-converter. In the case of a 1,4x converter you lose one stop and with a 2x converter two stops. To assure correct functioning of the camera, lenses with an f value of minimum 4.0 are necessary.
Can I use my 35mm conventional lens on my digital camera?
We do not recommend the use of conventional Tamron lenses on digital SLRs, as the resulting image quality does not meet the accustomed high quality standard that Tamron lenses deliver.
Generally, it is combinable but should be used in the central focusing field of the respective camera. Tamron has developed special lenses for the high requirements of digital cameras. These have a high resolution, coupled with the best possible correction of the most common aberrations, such as peripheral light fall off and chromatic aberration. Particular emphasis is placed on the lens coating in order to minimize the increased risk of ghosting and flare with digital cameras.
The following lenses are particularly optimized for digital SLR cameras:
Which Tamron lenses have a built-in motor for use with Nikon D40/D40x/D60?
Tamron has a total of 12 lenses with a built-in motor for Nikon (Nikon II mount) D40/D40x/D60 in its current line-up.
Are Tamron lenses compatible with digital SLRs?
The designation “Di” (Digitally Integrated Design) marks a generation of lenses, which have been specially adapted to the requirements of digital SLR cameras. Tamron’s Di-II lenses are designed exclusively for digital SLR cameras with APS-C size imagers (24x16mm or smaller).
The lens barrel of my AF 28-200mm zoom creeps when I carry the camera/lens unit around my neck. Is this normal?
This is perfectly normal on account of the moving parts inside the lens and due to the power of gravity. Tamron developed a convenient feature, included in many Tamron lenses called „Zoom Lock“to prevent undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap. This enhances responsiveness in the field and helps protect the lens.

When using the flash function of my camera together with my AF 28-200mm (or 28-300mm) vignetting occurs in the image. How can I avoid this?
The reason for the vignetting which becomes visible in the image is the short distance from the built-in flash and its angle of illumination on the optical axis of the lens.
At the same time, the illumination of the subject is affected by the relatively large dimensions of the lens. This is particularly noticeable in the wide-angle range and with short subject distances; nevertheless, it is caused by the compact design of the lens and all lenses of this type.
To take remedial action, please use an external flash, as its angle of illumination is further away from the optical axis of the lens (shoe-mount flash, grip-type flash). Please, follow the instructions in the user manual.
Can the depth of field of my lens be adjusted?
The depth of field is an optical characteristic of a lens and cannot be changed or adjusted.
It depends exclusively on the focal length, aperture, subject distance and the circle of confusion which in turn is dependent on the imager format.
