I’ll be doing the Tamron 11-18 review here.
This is Tamron’s first ever wide angle lens for cropped sensor DSLR.
And it’s the worst Tamron lens ever made. Period.
I borrowed the Canon mount from Nick who got it from Amazon. The equally bad Nikon
mount of this lens is also available.
Everything is an issue with this lens. Chromatic aberration, distortion, vignetting, expensive, you name it. I don’t even know why Tamron bother making this lens at all.
Don’t waste your time reading this review, go straight to the Conclusion section to see what your alternatives are. However, if you are curious to know why this lens is so bad, then you’re welcome to read this review thoroughly.
Special message to Tamron: Whatever you guys do, don’t ever release this kind of lens again.

Tamron 11-18 Review – Sharpness
The center sharpness is very good in general. However, what really kill this lens is the border sharpness. It’s soft and noticeable to the naked eye, even at the maximum aperture of f/8.
See the result of this Tamron 11-18 review below.
Sharpness Scale (from Best to Worst):
(5) Excellent
(4) Great
(3) Good
(2) Fair
(1) Poor

| 14mm | n/a | Excellent | Excellent | Excellent |

| 11mm | Fair | Good | Good | Good |
| 14mm | n/a | Good | Good | Good |
| 18mm | n/a | Good | Great | Great |
Distortion
Distortion is also an issue on this lens. Throughout the zoom range, barrel distortion is very pronounced, especially at 11mm. To see what I mean, see the unconvincing grid distortion test below.
Vignetting
Vignetting is also an issue on this lens (see why I said this is the worst lens ever?). At any aperture and any focal length, vignetting is visible. See my vignetting test below for more details.
Chromatic Aberration
If you think distortion and vignetting is bad are not enough, the chromatic aberration level makes this lens the worst lens ever. The chromatic aberration is visible on any aperture at any focal length, especially on the corners.
Chromatic Aberration Scale (from Best to Worst):
(5) Negligible
(4) Very Low
(3) Low
(2) High
(1) Very High
Tamron 11-18mm f/4.5-5.6 Di-II Chromatic Aberration
| Focal Length / Aperture | f/4.5 | f/5.6 | f/8 | f/11 |
| 11mm | High | High | High | High |
| 14mm | n/a | Very Low | High | High |
| 18mm | n/a | High | High | High |
Build Quality
Back to: Menu • Introduction
Materials
High quality plastics. Made in Japan.
Zoom Ring
Zoom ring is pretty smooth.
Focusing
Focusing ring is also pretty smooth. However, the annoying thing is the focus ring rotates in autofocus mode.
The autofocus speed is pretty fast but a bit noisy.
Compatibility
The Di-II acronym means that this lens can only be used for cropped sensor DSLR. You cannot use this lens for a full frame DSLR (such as Nikon D3 or Canon 5D Mark II
) or 35mm film SLR camera.
Conclusions
Back to: Menu • Introduction
Well, you’ve read the introduction. I already said this is the worst lens Tamron ever made.
Everything is an issue with this lens.
To summarize, below are my conclusions:
Drawbacks
- Distortion is an issue
- Vignetting is an issue
- Chromatic aberration is an issue
- Expensive
- Need I say more?
Positives
- None (Well, its lightweight, but it doesn’t really help)
Good For
Nothing. Here’s your alternatives:
If you’re using Canon, get the Canon 10-22mm f/3.5-4.5 EF-S USM (Amazon, B&H Photo, Adorama, Calumet
).
If you’re using Nikon DSLR, get the Nikkor 10-24mm f/3.5-4.5 DX AF-S (Amazon, B&H Photo, Adorama).
Not So Good For
Everything. See the recommended alternatives above.
What Others Are Saying…

So-so performance from an (relatively) expensive lens. I’ve been playing with this lens attached to my EOS 400D for couple of weeks now and I’m affraid it’s not living up to my expectations, or it’s relatively high price. It’s way too soft…

On my Canon 30D, the lens is not quite as sharp as my kit lens (28-135mm). I also get some purple fringes on back-lit edges. There seems to be a lot of contrast, making it hard to get the right exposure – pictures tend to be very overexposed and underexposed in a single shot…

It's extremely fast and easy. Here's how - Start your online shopping by clicking any of these links: Amazon, B&H Photo Video or Adorama. Those are the sites that I personally use to buy almost everything for years. They are proven to be safe, secure and credible.
How will this help me? When you buy your lenses or anything else from them, I got a tiny fraction of the sales which I will use for paying the maintenance cost of this site. They will also lend me more lenses to review if I hit a certain sales target. The price you pay for any item from those sites is always the same whether you use the above links or not. The only difference when you use the links is that you help me keep this site fresh, alive and FREE for you and for all readers. So, it's a win-win situation for all of us. You, me, everyone.
Please note that I always put you, my readers, as a first priority. Although I sometimes those vendors lend me lenses to review, I am always unbiased in my review. "I will be brutally honest with every review. Don't expect me to always write good stuff about the lens." That's what I told my vendors. And thankfully, they're fine with it.
Finally, you're not planning to shop, but have some extra cash to give out, consider making a small, $5 donation by clicking the "Donate" button below. This can also help paying off the maintenance cost of this site.
I hope to keep serving and helping you with your photography needs.
Many thanks for your support and thank you for reading!
Cheers,
