Bought this to pair my EOS D7 MII, love at first sight.� Both in combination gave such amazing shots both indoors and out doors.� Love it every bit, the size, the weight the features all so so good.

I bought this lens almost a year ago .. It's built solid (even though it's plastic) has a good feel, and takes amazing photo's. The auto focusing speed of the lens is truly amazing! It focuses almost as fast as your eyes! Very smooth when shooting video. I've compared the pictures to those taken with my 70-200 f/4 L IS, which in my opinion is one of the sharpest lenes out there .. and it holds it's own! Very little chromatic aberration vibrant colors and very sharp. The LCD screen provides useful information, but I don't use it much. I've never used the 100-400 L IS II and I wouldn't expect this lens to be of that caliber. It's not weather sealed and made of metal like the L lenses .. but I don't shoot in extreme weather anyway so that doesn't matter. It's a consumer lens, not a pro lens!! What you have here is a very good lens, that's not heavy, takes beautiful pictures, all at a great price point. I'm not a pro or anything .. but I think this lens is a steal at this price ... well worth the investment.

I finally had a chance to use this lens during a winter weekend in Yosemite. �I can see no difference in image quality between this lens and the more expensive Canon L lenses. �I also have a 100-400mm and a 70-200mm Canon lens.

When I am walking round in nature seeking a variety of images, this 70-300 lens in combination with the 24-105 lens covers almost all situations. �This 70-300 lens is significantly lighter than the 100-400mm L lens to carry.

I still love my 100-400 mm lens, but I use it only when I am stationary (like in a safari vehicle in Africa, or on a boat cruise when the wildlife is vary far away).

I am very pleased with this new 70-300mm lens, as long at it is not raining, and it is being used during daylight hours.

With Canon cameras for 8 years. Bought this lens 2 months ago. Got surprised with sharpness after microadjust focus in my 80D and 7D MII. Is tack sharp, very fast focus, much better than previous edition. Shooting birds in flight now is a pleasure.

The first time I used this lens it really surprised me, I used it with my Canon 80D and my Canon 6D, and it turned out to be very sharp across all focal lengths. Also use it with a 1.4x teleconverter, and the image is not degraded.
Fantastc lens for wildlife photography, and light weight. Fantastic for travel photography. I think I'm going to sell my Sigma 150-600mm

Replaced the 55250 mm basic kit lens one; happy with it overall. Will be looking to replace it with a 70200 L and a 100400 L in the future. Great stabilisation on it, the little screen is a nice add-ons: I use it to convert the mm when I'm using it with APS-C (7DMKII) sensor. Would buy it again. #canadianuserreview

This lens is super sharp and perfect most anyone not wanting the extra weight of the L equivalent. The focus is crazy fast and the image stabilizer is fantastic.

I picked this lens up as my first zoom lens for my 80d and have been extremely pleased with it. The focus is very fast and accurate and the image quality is execelent for a non L lens. With its Image Stabilzaion I am able to film animals hand held while at 300mm. Can’t go wrong with this lens!

If you are on a budget or just starting out, this lens is awesome. I have had this lens out in -2 degrees and it performed flawlessly. The autofocus is quick, the images are sharp, the image stabilization is quick and the weight feels like you are carrying a small prime lens. I use this lens on a Canon 7D Mark II and I highly recommend this lens. I shoot whatever I feel like at any given time - Landscapes, Nature, Architecture, Ice crystals, Rocks, you name it - I shoot it.

I have had great results with this lens. I always hand hold for out door shots. I would recommend this lens as a good step up for the money. I used to own a 100 to 400 & had to go lighter. This lens performs very well .
