300mm

Comparing the Tamron 28-300/3/5-5.6 with the Canon 75-300/4-5.6 IS

Well, there’s no contest here for the best images. Those from the Canon EF300/4L are
clearly superior, with excellent edge and center sharpness and no chromatic aberration. Of
course that’s just what you’d expect from an $800 prime lens. Of the two zooms, the Canon
75-300 is slightly better both in the center and at the edge. Both zooms display chromatic
aberration, the Tamron 28-300 showing slightly more than the Canon 75-300. You may also
notice that the image from the Tamron 28-300 is slightly smaller than that from either
Canon lens. By my calculations it looks like the Tamron is around 5% shorter in focal
length as I mentioned earlier in this review.

«Macro»

At the 300mm setting the 28-300/3.5-6.3 can focus on an object about
10″ in front of the lens (about 19″ from the sensor or film plane), for a
magnification of 2.9:1 (Tamron specs). Here’s an example:

As you can see, distortion is very low. Like all close focusing lenses (as
opposed to true macro corrected lenses), sharpness does drop off at close focusing
distances. Some chromatic aberration is also visible at the frame edges. When operating
under these conditions, sharpness is usually maximized by stopping down to f11 or smaller.
The above shot was taken at f16 using the built in flash on the EOS 20D. Despite the
length of the lens, the flash on the 20D was high enough above the optical axis that the
lens barrel did not shade the image

Conclusions

In answer to the original question «Does the Tamron 28-300 deserve respect»,
I’d have to answer that it does. While I think you could probably do better with two
zooms, one covering something like 28-100mm and one covering 100-300mm, not everyone wants
to use two lenses. For those who don’t, the Tamron 28-300 may be an appropriate choice.

For example, the Tamron 28-75/2.8 (which I recently
reviewed) is a much sharper lens than the Tamron 28-300/3.5-6.3 (and it’s obviously faster
too). Both lenses cost about the same (just under $400) and are very close in size and
weight. For coverage of 28-75mm it’s pretty much a no-brainer as to which lens is the better buy (the Tamron 28-75/2.8, just in case it wasn’t obvious…). However, whether the additional 75-300 range is worth
the compromises in lens speed and image quality is an individual decision to make. For some people it is, for others it
isn’t.

The bottom line is that if you hate swapping lenses, need one fairly small, light, lens to do
everything, and you’re prepared to accept some compromises, the Tamron SP AF28-300/3.5-6.3
XR Di LD Aspherical (IF) Macro isn’t a bad choice. It also comes with Tamron’s standard 6
year warranty too, which is a nice plus.

Если начать с внешнего вида, достаточно хороший конструктив, удобен в использовании, единственный минус это легко выезжаемость так сказать, так что камеру держать либо горизонтально, либо ставить на защёлку! Резкость наводится опять же, достаточно быстро, не промахивается!
Качество картинки: основной минус это резкость, достаточно хорошая до 150мм далее слабовато, снимать желательно от F5.6! Из плюсов, цветопередача отлично, контрастность очень хорошо, лёгкий, дешёвый, фокусное расстояние, красивое боке, ИХМО! Дисторсия на отлично, хроматические абберации и виньетирование не наблюдал!

Focusing

In general AF was quite good. In bright light there was little «hunting» and
AF lock was generally positive. The lens isn’t silent but focus noise is certainly
acceptable. Focus speed was similar to the Canon 75-300IS.

However in low light situations at 300mm AF can get a bit «iffy». For example
at a light level needing 1s at f6.3 and ISO 100 (EV5), AF with a Canon EF300/4L was fast
and positive. With a Canon 75-300IS it was slower and a lot less positive, sometimes
failing to get AF lock. With the Tamron SP AF28-300/3.5-6.3 XR Di LD Aspherical (IF) Macro
there were times when I couldn’t get a focus lock at all, particularly when starting from
a point well away from focus. At higher light levels (e.g. EV8, or 1/8s at f6.3 and ISO
100), AF was fine.

At shorter focal lengths (e.g. 75mm), AF was OK even at the lower (EV5) light levels,
though there was sometimes a little more «hunting» than the Canon 75-300 zoom
showed.

Image Samples

In the next section of this review I’ve compared images from the Tamron SP
AF28-300/3.5-6.3 XR Di LD Aspherical (IF) Macro with those from the Canon EF 300/4L, the
Canon EF75-300/4-5.6 IS,  the Canon EF28-105/3.5-4.5 and the Canon EF50/1.8.
 Again, I chose these lenses because they were available to me at the time of
testing, and because they represent lenses that might be considered as alternatives to the
28-300 (at least they are in the same price range). All testing was done with the lenses
mounted on a Canon EOS 20D body. All test images were saved as High Quality JPEGs with the
camera set to parameter set 2 (sharpening, contrast, saturation all set to «0»).
The camera was mounted on a Bogen 3051 tripod with an Arc-Swiss B1 ball head. Mirror
lockup was used for all shots.

The EOS 20D is an APS-C format camera which means a frame size
of approximately 15x22mm. The Tamron SP AF28-300/3.5-6.3 XR Di LD Aspherical (IF) Macro
has full frame 35mm coverage. It would be expected that  performance at the edges of
the full 24x36mm frame would be worse than those seen at the edges of a 15x22mm frame, but
center performance would be unchanged.

NOTE: All these crops are shown at 200% in order to accentuate any problems and better show differences. Remember that a 200% crop is like looking at a section of a very large print. Just how large depends on your monitor resolution and size. For example if you’re using a monitor which gives you a 12″ wide image (typical 17″ monitor) and you’re viewing at 1024 x 768 pixels, a 200% crop represents a section of  what would be an 82″ x 54″ image! So if the images look a little «fuzzy», that’s the reason why! At normal print sizes (say 8×10), many (in fact most) of these crops would look pretty sharp.

Introduction

The Tamron 28-300mm f/3.5-6.3 Di VC PZD is a wide-angle to telephoto zoom lens designed for 35mm full-frame sensor DSLRs. Boasting a new splash-proof design and features such as a Piezo Drive focusing motor, VC (Vibration Compensation) technology to combat motion blur, moisture resistant construction and a 49cm minimum focus distance and a maximum reproduction ratio of 1:3.5, the Tamron 28-300mm f/3.5-6.3 Di VC PZD costs around £619 / $849 and is available in Canon, Nikon and Sony fit. The Sony model comes without the VC image stabiliser because Sony cameras already have it built into the camera body.

100mm

Comparing the Tamron 28-300/3/5-5.6 with the Canon 75-300/4-5.6 IS

At 100m and looking at the center of the image, the 75-300IS is sharpest at f8,
followed by the 28-300 and the 28-105. At f5.6 things are pretty similar. Wide open, the
28-105 ( f4.5) loses some contrast and sharpness, while the 28-300 (f5) holds contrast and
sharpness well.

At 100mm and looking at the edge of the frame it’s clear that the Canon 75-300IS is the
sharper lens at all tested apertures. The Tamron 28-300 and Canon 28-105 are pretty
similar at f5.6, but I’d give the 28-105 the edge at f8. The 28-105 does show a little
more chromatic aberration than the 28-300 though.

Overall I’d say that the best performer at 100mm is the Canon 75-300 IS, with the
28-300 and 28-105 being pretty similar at equal apertures.

Aperture and Focal Length

It’s evident that Tamron struggled quite hard to get to 300mm and f6.3 with such a
small and light zoom lens. My measurements show that the true maximum focal length is
about 5% less than a Canon 300/4L. I’ve previously measured the EF 300/4L at 295mm, which
suggests that the maximum focal length of the Tamron 28-300 is closer to 280mm than 300mm.
Normal industry tolerance on focal length is +/- 5%, so at 280mm it’s close (actually
about 6% short). I also noticed that the indicated shutter speed (EOS 20D, Av, evaluative
metering) with the Tamron lens set to 300mm and f6.3 was always 1/3 stop slower  than
with either the Canon 300/4L or the Canon 75-300 IS at 300mm set to f6.3. This suggests
that the effective wide open speed of the Tamron 28-300 at 300mm may be closer to f7.1

I should point out that falling slightly short of specifications isn’t all that
unusual, especially for zoom lenses. For example Popular Photography found that a well
known camera manufacturer’s 75-300/4-5.6 zoom was actually 282mm and f6.0 wide open and
zoomed out fully. Shortfalls in either aperture or focal length are certainly not
desirable, but they are common.

Автор реплики: Газаров Артур

После долгого и мучительного выбора, бесчисленного просмотра ужатых Жипегов и затяжной головной боли, наконец, решился и купил этот Тамрон.
Сигма 18-200 отпала сразу: интересует больше «длинный конец», в дальнейшем планируется переход на 5D, плюс не исключен вариант покупки пленочной тушки.
24-200 Токина хоть и хороший «линз», но большой и тяжелый. Сигма 28-300 вызывает неприятные ощущения.
Кэнон 28-300 неприлично дорогой, белый и тяжелый. Хотя может когда-то на него и заработаю.
А универсальный объектив нужен для отпуска, репортажа и т.д., когда нет возможности менять 2 объектива. Искался объектив чисто для съемки на улице днем, больше в солнечную погоду.
Также нужно, чтобы обращали как можно меньше внимания.
Купил на Горбушке. Что интересно, те, кто торгует исключительно Сигмами и Кэноном во всю поливают грязью Тамрон.
Типа часто ломается, много возврата, весь Тамрон левый, народ ругается. Поэтому и не продаем.
Ну не знаю, насколько это так: на коробке написано For USA or Canada use only. Левый не левый – год гарантии Fotomarketа.
Внешне симпатичный, приятный на ощупь, тугой ход. Весь пластмассовый – посмотрим, что будет дальше. Байонет тоже пластмассовый, хотя там типа спец наполнитель компаунд с добавками для прочности. Бленда, конечно, паршивейшая – кусок игрушечной пластмассы. Есть замок зума, хотя и так под своим весом не выезжает. Что интересно везде пишут вес -420 г. В его же спецификации – 430 г. Может «леваки» на 10 гр. Тяжелее оригинала
Конечно, это не проф техника и я полагаю, что через год он у меня будет люфтить, забъется пылью и вообще сдохнет…
Фокусируется довольно уверенно. В условиях плохого освещения немного «нервничает». Моторчик тихо жужжит…
Фокусировкой я доволен. С 20-кой цепко. Кэноновские стекла получше будут в плане фокусировки. Но разница не сильная.
Картинка приятная: не мыльная, ну и не супер-пупер, конечно не «никоновская» резкость. Так — вполне нормально…
А вот цветопередача отличная, приятная и правильная. Нравится!!!!! Это не сигмовский рисунок, который виден даже на цветной ксерокопии снятой с распечатки….
Похоже, Сигма использует то стекло из к-го делают зеленые бутылки – шутка, конечно. Но ее цветопередача в целом не нравится…
Объектив размывает фон приятно. «Бубликов» я пока не заметил. На 300 мм ведет себя прилично, этого я даже не ожидал. Считал, что будет сильно мылить – все в пределах нормы.
Понравилась картинка на 300. Есть фиолетовые ореолы на контрастных границах, но не смертельно…
Здесь вопрос в другом. Объектив очень легкий и этой пушинкой трудно избежать шевеленки на длинном конце.
В этом плане большие и тяжелые телевики преимущество. Придется купить легкий штативчик.
В целом впечатление приятное. Для той цели, для которой покупался вполне годится – естественно не на все случаи жизни.
Повторюсь, съемка в поездках, репортаж – только на улице, днем. Объектив больше понравился, чем не понравился.
Дороговато, конечно – 12990 рублей. Его красная цена — за эту пластмассовую игрушку 300 баксов.
Искал б/у, но так и не наткнулся на соответствующее объявление. Ну и решился, а там посмотрю…

Следует расшифровать все обозначения по порядку:

• AF — автофокусный объектив
• 28-300 мм — фокусное расстояние (для 35 мм камер)
• XR — high refractive — объективы отличаются не только укороченной габаритной длиной, но и уменьшенным диаметром при сохранении оптической мощности и светосилы на прежнем уровне. Это удалось реализовать благодаря применению линз из специального стекла с повышенным коэффициентом преломления (XRGlas). Результатом стали объективы с очень маленькими погрешностями изображения, и при этом с уменьшенными габаритами
• Di — объектив разработан как для цифровых зеркальных камер, так и для пленочных камер. Подходит для полноформатных камер и для камер формата APC
• VC — Vibration Compensation —
  система подавления вибраций, подобные системы называют также стабилизатором изображения. Эта система применяется для подавления вибрации рук фотографа, вибрации от нажатия кнопки спуска затвора. Эта система особенно важна, если приходится часто снимать с рук, в темное время суток или на больших фокусных расстояниях. Система подавления вибраций может быть отключена при необходимости
• LD — low dispersion —
  Элементы LD изготавливаются из специального стекла, обладающего чрезвычайно низким коэффициентом цветового рассеяния (этот параметр указывает способность стекла расщеплять луч света на составляющие цветового спектра).
  В результате обеспечивается эффективная компенсация хроматической аберрации, т.е. проблемы, особенно актуальной в телескопических объективах с большим фокусным расстоянием. Хроматическая аберрация – это форма оптического шума, который уменьшает резкость изображения.
• AD —
  Стекло с аномальным рассеянием – это специальный вариант оптического стекла, обладающего аномально большим соотношением частичного рассеяния (величиной рассеяния в определенном диапазоне длины волны в пределах видимой части светового спектра) относительно специфической длины волны. Комбинирование элементов из стекла AD с обычным оптическим стеклом, обладающим различными характеристиками рассеяния, позволяет контролировать коэффициент рассеяния волн специфической длины. Это ведет к эффективной компенсации осевой хроматической аберрации у телескопических объективов, а также боковой хроматической аберрации у широкоугольных объективов традиционной конструкции
• IF —
  Система внутренней фокусировки объективов Tamron улучшает оптические характеристики за счет минимизации виньетирования и подавления аберраций, обусловленных фокусировкой. Кроме того, сокращение предельного расстояния, с которого возможна наводка на резкость, позволяет выполнять макросъемку в диапазоне Megazoom (28-300 мм = 1:2,9)

Tamron AF 28-300mm f3.5-6.3 XR LD features Rotary (extending) zoom method where the length of the lens changes as you zoom in or out. This makes it possible to design the lens with a smaller minimum length ( generally when it is zoomed out) compared to internal zoom lenses. The disadvantages of this design are being harder to seal against dust and moisture, weight balance shifting while zooming and zoom creep in certain lenses.

Zoom Lock

Tamron AF 28-300mm f3.5-6.3 XR LD has a Zoom lock feature which eliminates Zoom creep where focal length of the lens changes with gravity when it’s held downwards or upwards.

Where to buy?

Caveat Emptor

I’d recommend shopping with Amazon.com, they not only sell directly, but a few reputable stores like Adorama and J&R sell through them too. I’ve been buying most of my gear through Amazon for the last couple of years and I’ve had zero problems so far.

The Tamron 28-300/3.5-6.3 Di XR is available from Amazon.com, with free shipping and a 30-day return policy. Note: If you purchase from Amazon (rather than a 3rd party selling via Amazon) between January 3rd and January 16th 2005, you get a$30 promotional certificate from Amazon which gives you $30 off most products sold by Amazon [See Amazon website for full details].
