Unlock the full potential of your camera. This lens is as sharp or sharper than my prime lenses. It has a professional quality build to go along with the unmatched sharpness. If you want to get serious about your photos then this lens covers you from 18-35mm (27-53mm). The only limitation (negative) is the limited focal length...but up until this point in time only prime lenses had the specs of this lens. Actually, this lens is in a category of its own; no other zoom lens has a constant 1.8f.
Pros: When it focuses where I want, the image is stunning. Good low light captures of still objects. Cons: It takes skill to use I use a T3 Summary: Build quality is good, the Lens quality is great, it certainly does what it says, just realize what you are getting. Autofocus takes a while, but there's a reson for it. Before I review the product, I always like to know the reviewer's perspective. I consider myself a seasoned novice photographers. I've takes my fair share of photos in many different settings on multiple continents. I even spent more than a couple hours trying to learn something about photgraphy. And I enjoy it and probably spend too much money on it. But I don't do this as a living and I don't get asked/nor will I ever be a primary photographer at a wedding (although, my realtives have used some of my shots from their wedding albumns) **Okay the review part** So the biggest thing about this lens is the apeture. I bought this lens because of the f/1.4. And it is great! I get butterry bokeh...if I can get relatively still compared to my subject. But I find that its actually quite difficult to. I should say that I typically take photos of my toddler in close quarters indoors. Its hard to get him to smile for the camera let alone stay still. Even when he is distracted and still, I find it hard to hold myself still enough (at f/1.4) to get his entire face in focus. The tip of nose might be in focus, but not his face, And I know what you might be thinking, "Well yeah, you have a very narrow depth of field at f/1.4. Duh!" Yeah, but I didn't realize just how picky it would be. And that's probably why it takes so long to autofocus or can't focus. Because you have to be very still relative to your subject. I will say, that if I get the focus, almost there, the autofocus is sometimes quick, but I think that might ruin the motor (manually adjusting the lens while in AF mode) so I don't recommend it. Anyways, If I had to do it over again, I would have gotten the f/1.8 because I'm not skilled enough to use the f/1.4. Shoot, for my kid's photos, I might need to stick with the f/4 of my standard lens. We'll see. But the build quality is good, the Lens quality is great, it certainly does what it says, just I didn't understand fully what I was getting.
I am very happy with this lens so far. I purchased it one month ago and have used it on a few occasions so far. The picture quality is my favorite feature of this lens. However, i feel the lens lacks in quality. As far as image quality goes, this lens is very sharp after F/2.0. This lens reproduces color very accurately, one of the best in the canon lineup. The colors, plus the great contrast and high resolution make this lens top notch in picture quality. As far as build quality goes, i feel that this lens could have been made better. The lens feels very sturdy when you hold it. However, the focus ring does not turn as smoothly as one would expect from a USM lens. This problem alone is what gives me the impression that the lens might not be built as well as it could be. If this lens was built like the 85 F/1.8 i would be 100% satisfied. However, this lens is a major step up in quality from the 50mm F/1.8 that i had.
