Following reasons why I took one star off:
- Horrible CA in certain situations.
- Barrel still too loose. I wish the lock was applied on all positions rather than just the transport.
Having said that, after about 2 months of use, I still have not gotten to the point where it slides on its own while tilting, but looking at the progress from the day I received it, how quickly it gotten loose, it might happen. Again, speculation based on extrapolation, may not be true. I will update the post in few months again.
Other than above 2 gripes, this is tremendous value lens. I can't boast enough about it. Combined with DXO Pro 9 software, this lens delivers no less than professional images. Look at some of the images I uploaded of my backyard wild life.
The hawk was sitting 14 feet from the lens (Once in a life time opportunity) on my deck!
First off, buy your Tamron lens from an authorized reseller to get the 6-year warranty coverage. Look for the shiny stamp on the box and it should say "... Authorized Dealer". I gave this 5 stars because it functions as advertised. This lens extends for zoom and it is a little bit stiff, maybe because it is brand new. VC works and is quiet. This lens is really good as it is touted -all-in-one lens. From macro, wide angle to zoom, the pictures are crisp and vibrant. Bokeh is fairly decent, too. One noticeable cons for this lens is the chromatic aberration or color fringing. The magenta tint is prominent especially on bright shots on all ranges. But this is easily fixed from your software. More effort is needed for indoor and night shots (3.5 - 6.3).
Note that this is not for your professional award-winning shots. This is best for travel or everyday photography. Please do not compare this to your expensive Canon L or prime lenses, enough of that. I have some, too. I bought this to enjoy taking pictures of people, places, things, animals, family and friends, and not pixel-peek nor dissect its technical aspects.
Cost-effective, sharp, VC, and excellent range - I say this is a keeper.
Lens Breathing and other lens phenomena
I’ll make some documented criticisms in this review. Before that I want to recognize that an 18.8:1 zoom makes the lens pretty amazing.
I find 3 issues with my copy of the Tamron 16-300mm lens.
There is some fairly noticeable chromic aberration (CA) at “300mm” in the off-center areas. It is possible to remove much of the CA in a photo editor. Please see 1st TAM photo for an example of green and magenta CA toward the edges of the frame. The actual CA is worse than shown in this crop. The CA is many pixels wide at this f6.3 (full open) aperture. Also note the somewhat softer lines away from the center. Lines sharpen as one closes the lens to f8.
I’ve discovered a more serious situation while testing this lens. The lens shows a significant amount of “focus breathing”. Amazon may block the actual URL. Goggle focus breathing + bobatkins for an excellent review of this phenomenon. Basically this refers to the fact that a 300mm (or any lens) has the stated FL only when focused at infinity. At closer distances, many lenses will behave as a shorter FL. This shortening will vary. He also offers a very readable explanation of the phenomenon.
I always test every lens and lens filter I purchase... I have a fine-line lithograph lens test chart and 4 floodlights. I can move back far enough to allow the chart image to just fill an APS-C sensor using 200 to 500mm lenses.
I bolted the Tamron to my Sony A77, placed the camera on a tripod and zoomed to 300mm. I’ve tested enough lenses to know about where the tripod should be for a 300mm-rated lens. My observation was that I had to move the tripod significantly closer to the target in order to have the target totally fill the sensor. I snapped the TAM56 photo at f6.3 (wide open) and observed the CA. I closed the lens down to f8 and observed less CA.
Next determine why I had to move the tripod so much closer to the target. I substituted a Sony 55-300mm. Not nearly the zoom range of the Tamron. But, it covers 300mm. That image, taken with the tripod in the same location is shown as SON58. Lens was wide open at f5.6. Center is very sharp, edges remain sharp. CA is minimal. The notable item is that only a part of the test chart fills the sensor. Either this lens is significantly greater than 300mm – or – the Tamron is significantly less than 300mm.
What is the actual difference? I backed the Sony to a lower zoom, until the target just filled the sensor (image size similar to image taken with the Tamron at 300mm). The EXIF data showed 160mm. See image [email protected]
To make comparisons easier, I’ve combined TAM 56 and SON58 in one frame.
The conclusion is that with the Tamron lens set to 300mm, at 8’ distance, the image size recorded is equivalent to the Sony set at 160mm. A “heavy breather”.
That’s a complete set of data. It, however, begs the question – what do other lenses do under these test conditions?
I next looked at a Minolta AF 75-300mm.
SEVERELY TRUNCATED TO FIT THE AMAZON GUIDELINES - ask questions
I was using various Tamron lenses since early 90’s and I don’t understand why the quality of their lenses decayed drastically during the last few years. Was it after Tamron moved manufacturing process to China? As shipping from Amazon delayed about 4 weeks, I picked another one locally. After the first one finally arrived, I’ve got a chance to test two samples of this lens. Therefore, I can rule out dealing with a bad sample.
The build quality is good and the focusing was fast and accurate at all ranges. Nevertheless, this superzoom lens has two main problems:
(1) While the focal length is somewhat correct at the wide range, it is not even close to 300mm at the maximum telephoto setting. I was comparing it to several lenses, including Canon EF 100-300mm, Canon EF-S 55-250mm, and older manual Tamron SP 60-300mm. The maximum zoom setting (300mm) in reality corresponds to 250mm at best.
(2) The IQ is very low at extreme zoom settings. I was comparing the 16mm with Tamron XR DiII SP 17-50mm which outperforms this superzoom at all apertures. At 300mm, it frames close to Canon EF-S 250mm, but the 5x times less expensive Cannon gives significantly sharper images at the same aperture settings. And the old Tamron SP is crispy sharp at 300mm! This superzoom is not even close.
Overall, this lens is physically is 17-250mm, but only useful at 50-100mm, this is it.
I really wanted to have this superzoom lens for traveling, but I really didn’t expect such low IQ at this premium price tag. I prefer rather to carry two lenses then compromise the quality of my shots. I would probably keep it for $100-200 range, but for $600+ one could expect much better.
This lens is only okay. I read multiple reviews and watched many videos on this lens and was really excited to hear how sharp the photo's are and how great of an all around lens this is. After taking it on a trip to California with me, I used it once, uploaded the photos, found that the photos are not sharp at all, especially at the full 300mm. I haven't used the lens since and plan on selling it. For the price it's a decent lens, especially if you aren't aiming for high quality sharp photo's. If you are looking for that sharp detail especially when you're zooming in, I wouldn't recommend this lens.
I own a couple Canon L lenses, and while they do produce a sharper image with less chromatic aberrations and greater contrast... this is the lens that sits on the camera most of the time. It produces a decent image and the versatility makes up for its shortcomings. So unless the situation calls for that last few percentages of image quality- this is my walking around lens.
I switched from the SAL(Tamron) 18-250mm to this 16-300mm lens for my Sony a77-M2 - and I was blown away by the better quality of this lens. It's exceeded my expectations. If you're looking for an all-in-one walk around lens I think you'll be more than happy. There is some chromatic aberration at some focal lengths (especially at 16mm) and some softness at the long focal lengths - but both are easily corrected in image processing. I've attached a few sample snaps (16mm and 300mm) and close up macros. The rock the barnacles are attached to is about 1.5" long.
Aún no lo he probado por falta de tiempo, sin embargo no tiene control de vibración por eso lo callifico con 4, por lo demás llegó en tiempo, es muy silencioso y enfoca rápido espero este fin de semana salir a probarlo con fotos a las distintas distancias focales
This lens may be the finest lens for both amateur and professional photographers as it incorporates macro, wide angle and focal length up to 300mm. Though a bit heavy, it compensates carrying a bag full of lenses and the bother of changing lenses. I love it.
Very good lens! Auto focus isn't loud and the stabilizer works great. The low light results are better than I thought they would be. The only issue for me is the f3.5-6.3, I shoot mainly video and have to be mindful when zooming in and out. All in all a great multitasking lens!
Bought this lense when the AF on my 18-270 gave trouble and focus became unreliable. Excellent lense. I use it on the Canon 7D and 7DII. I don't know why they build lenses without full time manual focus. My 18-270 did not but this one does as does the 28-300 for full frame. This lense is sharp and the AF can keep up with the 7DII in high burst mode (10 fps) while exposure bracketing. Me thinks that had something to do with the 18-270 giving trouble.
This is the best lens ever. I can take pictures close up or bring back items for a closer look. With a 16-300mm lens, I have no limits. The perfect lens!
Muy buen producto llego antes de lo esperado, es buen material de construcción, sin embargo tiene ciertas aberraciones de color en la imagen final, claro no son muy obvias pero llegan a notarse, en foto amateur considero que es bastante bueno este lente a parte de ser todo terreno.
This is a terrific all purpose lens. Has done thousands of pics and is great
So nice to be able to take pictures without having to switch lenses
Excellent lense. Well made and sharp.
Good optics. I love the focal length range.
Este lente produce fotos con distorsiòn en la apertura de 16mm. Es una pena que no supiera esto antes de comprarlo...
Very versatile, with just a small sacrifice in image quality but still very good!
