I have had this lens for over a year and regularly shoot with it. Here is what you will want to know.
(+) denotes a pro, (-) denotes a con and (~) denotes ambivalent remarks.
(+) This lens will only work on a Canon crop sensor body (all the rebels, 20D, 40D, 60D etc all the way up to and including the excellent 7D which I use this lens with).
Why do I mark that a (+)?
Crop sensor bodies naturally look like zoomed in naturally because they only record the center of the image created by a full-frame lens. On the other hand, full-frame lenses need to have their full image quality (IQ) over the whole full frame sensor, while the crop sensor cameras just don't care about that extra picture.
I chalk it as a plus because Canon could create a really wide angle lens that only generates the picture that will be recorded by a crop sensor camera, solving the crop sensor / wide angle issue.
Unfortunately this means that if you could use the lens on a full frame, the image would not cover the whole sensor. Because of that it will not mount on full frame bodies and canon could not call it a L lens.
(+) This is a very wide angle lens - best for landscape, architecture (more on that below) and sports from up close but NOT FOR PROTRAIT and certainly not for getting the glitter in the eye of a raven half a mile away.
I shot a picture from above the corner of a rectangular table and I got both side appearing almost parallel to the frame sides. This means an angle of field of about 90 degrees. This might not seem impressive but this is HUGE when you think the lens is rectilinear (more on that below).
(++) Excellent (excellent!!) optic quality. Performances seem to me very comparable with the EF 16-35 L IS USM used on a full-frame sensor (6D and above). The 16-35 goes for $1700 and of course is f/2.8.
Most people agree that the IQ is fantastic and Canon all but admitted that they would have called it a L-series lens had it been compatible with full-frame bodies.
(+) The lens is reasonably fast: f/3.5 at 10mm and f/4.5 at 22mm. This might not sound very fast but the rule of thumb says you can shoot hand-held at 1s/focal distance, i.e. down to about 1s/15 at 10mm (counting in the crop sensor factor).
(~) No image Stabilizer (IS).
The reality is: at such wide angles you can hand-hold at such low speeds already that the IS would have to move the elements very far to compensate for very low frequency oscillations.
Event the $1700 16-35 has no IS and no-one thinks the worse for it.
At least you won't forget to switch the IS off when shooting from a tripod.
(~) The maximum aperture varies with the focal distance: f/3.5 when very wide angle, down to f/4.5 when merely wide angle. This means that you cannot set your camera in manual, measure your light and then shoot away.
This is most likely not going to be a major issue for most uses and even for most users. As soon as you use anything but the fully manual mode (or bulb) this is a non-problem.
(+) This is not a fisheye; it is a rectilinear lens, i.e. NO BARREL DISTORTION. This means that a straight line in the real world will appear as a straight line on the picture. This makes it a prima facie excellent choice for architecture work.
However beware: when shooting groups of people, the faces on the sides of the picture will appear elongated. This does not mean you can't use the lens for group shots (I do), but I find myself adding some barrel distortion in post-processing for the people on the side to look normal. Any reasonable software will do that (dark table, lightroom, photoshop elements, aperture etc.).
Again, for shooting architecture this is fan-tas-tic.
All in all
This is NOT a walk around lens.
If you don't do much landscape or architecture you might not need that lens but really this is you decision. If you don't know, try one in a store or better borrow or rent one for a day. Then you will know.
I bought it here on Amazon for about $760 and I would buy it again at that same price immediately if I lost it. At the current $600 sticker, I think it is really worth it.
The item was packaged well and delivered on time. It worked right out of the box. There are a ton of apps available both for fun and games or productivity. The tablet is fast and responsive. Many useful apps were provided by Samsung. Great product...would buy it again.
This...I....oh my god...This book is fanTASTIC! It's got a great plot line, and isn't all just sex. Yes, there is a LOT of sex written, but it's not cheesy or misplaced, and there is an actual plot line to this book! I'm very excited to read the rest of the Fifty Shades Trilogy.
Now, to figure out how to look at Seattle again without blushing...
This book was amazing! A guy friend of mine had given me some tips from it years ago and recommended I should read it. I finally got around to buying it a couple of months ago and finally sat down to read it. It offered great tips about communication and gender differences. I often found myself reading the sections geared towards men and thinking "Yes! That's exactly how I would like a guy to act!" So I have faith that the sections that are geared towards women are accurate in their suggestions. In fact, I have toyed around with some of the ideas she gives and they honestly worked. I'm sure it isn't the ONLY reason that the guy fell for me, but it certainly helped! I 100% recommend this book for girls AND guys. Even for those of you who are skeptical or not looking for love, it still brings to the table some really interesting sociologial studies and impressive facts! Happy Reading!!
