A fantastic Lens if you're a photographer missing a wide field of view in your photography. I've been using it extensively in the field for a month now in the Northern Ontario region. I've had it in the middle of rivers on a tripod, in front of waterfalls and it really seems to hold up. As big a lens as this is, it's actually very light in weight than what it looks, believe me, but I'm the type of photographer where size isn't an issue. The things I love most about this lens is it's 2.8 aperture and image stabilization. If you're into astro-photography this lens is for you. The only downside about this lens is you can't use traditional len's filters. BUT, there's aftermarket brands already selling filter systems for this camera (a little pricey though). I was shopping around for similar len's and nearly all of canon's ultra-wide angle lens's are around $2k or more. This lens easily goes toe to toe with canon's 16-35 2.8 II so I strongly recommend this lens as an alternative. Read more

The reason why I am giving 1 star is because both copy of lens I received from Amazon.ca are grey market lens. For those who buy this lens, I suggest you verify your copy with Tamron Canada for 6 years Canadian warranty. I bought my copy from Amazon.ca (Ship/sold by Amazon.ca) and expecting it shall have legit 6 Years Tamron Canada warranty as Amazon.ca is listed as an Authorized Dealer from Tamron Canada website. Took less than 2 days to received my lens, Amazon did a great job on fast delivery. Took some shots in different focal range, no focus issue and image quality are sharp across the picture. After verified I got a good copy of lens, I email the company who handle Tamron Canada Warranty service (Amplis Foto) to register and verify my lens has legit 6 years Tamron Canada warranty, the gentleman in the email confirmed that my copy of lens from Amazon.ca is a grey market lens, which will not have any Tamron Canada warranty nor they will fix it if something wrong with it. Fine, so I contact Amazon.ca for replacement and the rep ensure me I will get a copy with legit 6 Years Tamron Canada warranty. Two days later, I received my replacement copy in the mail and I contact Amplis Foto to verify right away for warranty verification. Unfortunately, rep at Amplis told me this replacement copy I got does not have 6 years Tamron Canada warranty either. Contact Amazon.ca again and they said they will have to refund me the money and do an investigation on this matter. Therefore, I end up bought the lens locally from another Tamron Canada authorized dealer and confirmed the lens I bought has 6 years Tamron Canada Warranty. The lens is well build, even tho it's mostly plastic outside but it doesn't feel cheap. Image quality on this lens is amazingly sharp and outperformed Nikon 14-24 F/2.8 by a bit based on most of the online review/comparison. Pro: - Very good image quality and very sharp corner to corner. - Well constructed and build - Half of the price compare with Nikon 14-24 F/2.8 - Very fast focus on my Canon 6D Con: - HEAVY!, this lens is 100g heavier than Nikon 14-24 F/2.8 and it's almost double the weight of Canon 16-35L F/2.8 II or Canon 16-35L F/4. - No cheap solution for lens filter. Overall, I am very pleased with the lens. Read more

I was looking for a ultra wide angle lens for my canon 6D for low light and astrophotography. I did a lot of research and my conclusion was this Tamron 15-30 mm f2.8 lens. For low light and astrophotography, this lens did the job very well. Before I was using an art series 20 mm sigma f1.4 but the coma was very noticeable. The sigma lens was sharp and let in an amazing amount of light but if it wasn't for the coma, that would be my go to lens. The Tamron I do have to set the ISO and shutter speed a little higher / longer but a huge improvement with the reduced coma. Overall for landscapes and cityscapes, the sharpness is amazing. It is at the same level and the canon L series 16-35 mm and the Nikkon 14-24 mm but more cost effective. The autofocus is fast and accurate. The Vibration control is solid. This is now my go to lens for wide angle, astro and low light photography. With all the reviews I've come across on-line, the one comment is the weight of the lens. Yes it is a heavy for a lens but I've hiked with this with a few other of my lens and relatively speaking, it isn't as heavy as people make it out to be. They make it sound like you're carrying a brick. Amazon is he cheapest for this lens as well... I highly recommend it!!! No regrets what so ever... Read more
