Question: Just upgraded my EOS body to the 70D.  Is this lens compatible with it?
Document: If quality, reliability, flexibility, stability and speed are your game and you take your photography seriously, then this lens is for you. After all, you can buy another body but a lens you keep for a life time.
It has the added advantage that it keeps the camera/lens close to your body when hiking rather than swing out and hit something that the neck strap is prone to do.If you are looking for a one lens solution look no further. It is the L lens to get...
one suffered that fate. To tell the truth, even indoors might as well be considered the "field" here. The first thing I noticed after I attached it to my T1i body was the great amounts of air whistling in and out of the cracks in the camera body and viewfinder, when you slid the lens through it's zoom range.
I was salivating for this lens for four months and finally bought one a few weeks ago from the Amazon. I was very excited and couldn't wait to put this glass on my 20D.First impression I got was that this lens is not that heavy as 3.7 pounds may seem, but boy I was wrong about that. It feels solidly built and looks not that huge on the body.
This is the best One-For-All-lens for your Canon body--as long as it is a 1.3xFOV body like that is 1DMkII, 1DMkIIN or 1DMkIII. For my liking it's too long on the wide end for a 1.6xFOV body. Versatility and quality are as outstanding as color and contrast. You can get pictures that you otherwise would not get without this one lens. The IS makes it perfect for almost all situations.
If you are on the full size sensor professional EOS cameras, it gives you that wide angle versatility.It is heavier and a little larger then some lens, but for the quality of glass you are getting, I do not mind.The only thing I do not like about this lens is that there are no lock outs on the auto focus and  lens function buttons.
makes it into a "Lens Camera". Carrying this lens with the camera attached is also very easy, whole set up less than 10 inches long, only the grip side of camera is slightly wider than lens.I have no reservations on lugging this lens around with this set up.So if you are hesitant about getting this lens because of weight, pair it up with the EOS-M ! !
This thing is a two handed broadsword and it's not for everyone. The one thing you're going to want to get is a good camera backpack, at least that's what I did after running around with this shooting for a couple of hours. I picked up a Lowepro Slingshot 200 camera bag and was immediately relieved of the immense weight, plus I was able to fit the camera, lens attached with the back of the camera body facing the side flap for easy extraction at a moments notice.
I purchased the EF28-300mm f/3.5-5.6L IS USM lens for my EOS 40D after grueling over it for months. It's a lot of money but after using it, it worth every dime. I had been using the 28-135mm lens and always found myself short in focal length for some shots. The 135mm just isn't enough for many shots.
I bought this lens because the 28-135 mm kit lens for my Canon EOS 7D was simply not long enough for taking wildlife shots. This lens also compliments my EF-S 10 -22mm ultrawide (my favorite lens). The quality of this long lens is top notch, however, it takes getting used to it's weight and that it's a push-pull zoom.
Answer: Yes, compatible with full frame and crop sensors.
