قابل رقابت با 24-70 نیکون می باشد.

قيمتش كه وسوسه كننده هست ، من به شخصه خيلي دنبال قيمتش بودم ولي چيزي گير نياوردم ، M.Mobin دستتون درد نكنه ، منتظر ريويو ها هستيم ، اگر در حد 17-50 تامرون باشه ، يكي از اولين خريدار ها هستم

ریویوی سایت ephotozine از این لنز منتشر شد.
شارپنس بسیار خوب در دیافراگم های میانی و کیفیت بسیار بد بوکه در این لنز مشهوده.
انتخابی مناسب برای عکاسی لندسکیپ و انتخابی نه چندان مناسب برای عکاسی پرتره و عکاسی خیابانی.

Tamron SP 24-70mm f/2.8 VC USD Lens Review

Tamron 24-70mm f/2.8 Di VC USD Lens Image Quality

[merdax]

ISO 12233 resolution chart results have been added to the Tamron 24-70mm f/2.8 Di VC USD Lens Review page.

I have two of these lenses right now. Unfortunately, the first lens I received needs to go back.

After spending 10 hours or so completing testing the lens on the ISO chart, it became clear that the lens was not working properly at the longer focal lengths. Image quality was unacceptable at 70mm. Tamron confirmed that the results were not as they expected.

The second lens performs much better optically. These are the results now presented on the 24-70 VC review page.

Before making your purchase decision, I encourage you to wait for me to spend more time evaluating the Tamron 24-70mm f/2.8 Di VC USD Lens' AF performance. Neither of the two lenses I have autofocus accurately on the test chart using a Canon-calibrated EOS 1Ds Mark III. I will minimally test the second lens behind a second calibrated 1Ds III and a 5D III.

Stay tuned for more information.

ظاهرا اینطور که بوش میاد کار قوی ای در نیومده

از اين بابت اونايي كه دنبال يه لنز 1000يوروي بودند بايد ناراحت بشند ، چون اينجور كه بوش مياد تامرون براي فروش بايد قيمت را كاهش بده (داستانVC 17-50 ) و اين براي كسايي كه دنبال يه لنز 600يورويي بودند ، خبر خوبيه

نمي دانم ،ولي در يك فروم فرنگي شخصي كه اين لنز را خريده بود ، 24-70 ورژن1 را داشت و به قدري از تامرون راضي بود كه قصد فروش كنون را داشت !
