Tamron's Di lenses featuring optical systems for use with both digital and film cameras have been highly evaluated by users around the world since the introduction of the first Di lens, SP AF28-75mm F/2.8 (Model A09), in 2003.
Many users strongly suggested that Tamron make the existing non-SP high power and compact 28-300mm lens they are using with their film cameras available in the Di design in order to realize the same convenience and quality images with digital cameras.
Tamron has redesigned the conventional AF28-300mm zoom (A06) to feature the Di design in order to meet the demand of those photographers.
High Image Quality by Virtue of Di (Digitally Integrated) Design:
• The "Di" design is achieved by first improving our BBAR coatings to a new multi-coating that encompasses all of the benefits of the original but now further reduces the ghosting and flare caused by aberrations, and secondly by further enhancing our already stringent quality control system.
The new AF28-300mm Di is redesigned as a high power zoom lens now ideal for use with interchangeable-lens digital cameras as well as film cameras.
1. Improved Coating:
• Newly developed Multi-coating ideal for digital imaging to reduce ghosting and flare caused by aberrations and to increase contrast
2. Enhanced Quality Control:
• Ensure mechanical and and optical meet new standard
3. Exterior design:
• Di logo on zoom rings
Same Convenience and Compactness:
• The amazing changes in angles of view of a 10.7X zoom lens are now available foryour digital SLR camera. This opens up a completely new horizon when combined with the fundamental attraction of digital SLR cameras; the possibility of confirming the quality or composition of captured images on the spot and the capability to allow the manipulation of images with a computer.
The new AF28-300mm Di enables photographers to enjoy the convenience of the high power zoom lens with digital SLR cameras, while offering the same compactness as that of the previous model designed primarily for film cameras.
Ideal for Use with Conventional Film Cameras As Well:
• The new AF28-300mm Di can be used with both digital SLR cameras and conventional35mm AF-SLR film cameras. It provides an impressive angle of view equivalent to that of approx. 465mm ultra telephoto when used with a digital camera and enables you to enjoy creative composition of images at the 28mm wideangle setting when used with a 35mm film camera.
I like this lens. I got tired of the weight of taking multiple lenses on trips and having 2 bodies or having to do lens changes with 1. This is no L lens, but I got lots of great pictures with it on my Canon 6D. I did have to fix chromatic aberrations form high contrast situations, but fortunately, that is pretty easily done in Lightroom.
I have the 28-300 Canon L. I am a amateur so build quality is not of huge importance even though the tamrons is good. Image quality is very close to the same as far as I can tell. Weight and size are a huge advantage. This is a fun lens to use. I can now carry it everywhere without embarrassing my family with the huge white lens. I will probably be selling the Canon. I use it on a Canon 6D.
I use this lens with a Canon 6D. It is very well built, not like a L but really nice, while small and light. The lens looks just the right fit when mounted on the Canon 6D! Weakest focal length is 28mm: hazy at F3.5 then F5.6 much better, but you need F8 for sharp borders (F11 for corners). Then coverage improves with focal length, and around 70mm good image on all the field from F8, then the lens stays very sharp at 200mm near F8 as well. At 300mm you get a really huge amount of radial chromatic aberration which can be annoying on high contrast subjects, though once corrected in Lightroom or ACR final results are surprisingly good if not very good; images at F300mm F6.3 are somewhat usable but F8 is really where you want to be. Close focus is a really nice feature though focal length are much shorter then, unlike infinity where the field of view is what you expect. My sample seems to be very well centered on all the range, the extension happens without any play. Zoom ring is on the firm side and precise, focus ring is smooth to rotate... perfect. Stabilization works well but you have to get used to the image jumping down a tiny bit when you activate the lens. Also I had to enter AFMA corrections to get good focus results. I plotted in Excel all the AFMA corrections for all focal length and I could align data between 28 value and then 100-300 region, the 35 to 70 range had to be left a bit more front focus. In practice, I find the lens a pleasure to use despite both rings are inverted for a Canon user. Having a 10X+ zoom on a full-frame is really an exhilarating experience. I would recommend the lens to someone who will control focus (set AFMA and use LV for critical images), also control aperture to get best sharpness. Using RAW files is a must because some corrections will be needed. Distortion is a bit high at 28mm then after is less a problem, some corner vignette but Canon lenses can be worse. Colors are fine. Obtained images in real life can be surprisingly good. The lens works well for casual shot, focus speed is OK for my modest needs. For travel, I'll use it in combination with a 16-35mm L F4 IS and the 8-15mm fisheye. My 70-300 L will probably stay home because while it is a much better lens optically (obviously) post-processing magic will do with the Tamron. In conclusion I give 4 stars but realistically it is difficult to fault Tamron on that one. Yes the lens won't replace a Canon 24-70 L lens for image quality (no way) but this Tamron is a very challenging optical design to built which may explain the high cost! Used properly results can be very good.
At least for the Canon 6D, this is the highest rated superzoom, higher even than the $2800 Canon superzoom. It's not super super sharp like the Canon EF 70-200 f2.8 II, which is the sharpest zoom I've ever seen, and one of the best lens I've ever used, period. But that lens required you to take along another zoom to get the full range, and if you are sight-seeing, you're wasting time, and eventually gonna drop a lens... :(( So, this is the best super zoom currently rated for the Canon 6D full frame. For crop sensor walking around, I'd rate the Sigma 18-250 as slightly better IQ, less vignette and warmer color.
I use this one on hikes in the rugged hills north of home. One lens covers from relatively wide angle to telephoto. I use this on a full frame Canon and have not been disappointed yet. Would like image stabilization but get by with cranking up the ISO.
I love that I don't have to change lenses all the time when I am out hiking. This is a great substitute for the 24-85 and 70-300mm lenses that came with my camera.
I got this for my nikon d600 thinking it would be a full frame lens and was very dissappointed that it was not. Also found the pictures to be very soft.
I bought this lens for a trip to Africa. Great lens for shooting wildlife. Great range from 28 mm.to 300mm. No need to change lens in dusty conditions. Great lens for the money.
I needed an all purpose lens for my full-frame camera. I have been pleased with my other Tamron lenses, so I had no qualms with purchasing this lens. I used this lens for the first time when on our recent vacation & was pleased with it.
I use it with my Canon 5D Mark II to take images in available light at church for its newsletter, with great results. Also, I use this combination for landscape and some macro photography, again with great results. The images are tact sharp across the photo. The lens is a great walk about lens, which gives me great flexibility.
