I've been more or less addicted to wide angle photography for the last 20 years or thereabouts. Unfortunately, ultra wide angle shooters have been left out of reasonably accessible digital slr photography until very recently. Now there are several viable name brand options available, namely the Canon 10-22mm f3.5-4.5 reviewed here, the Nikon 12-24mm f4, and the Zuiko 7-14mm f4. Because of the 3 different crop factors involved, these lenses end up being pretty close in (35mm equivalent) effective range; 16-35 for the Canon, 18-36 for the Nikon, and 14-28 for the Olympus. Many will caution against purchasing these lenses since they cannot cover the full frame 24x36 format, and cannot even be mounted on a regular body. In the Olympus' case, it doesn't matter since the company has staked its fortunes on the smaller 4/3rds sensor format, and has opened it up to other manufacturers such as Fuji and Panasonic. With the Nikon and Canon, you are taking a leap of faith that the companies will continue to produce 1.5 and 1.6 crop factor sensors into the future so that you will be able to take your crop-only lenses to upgraded digital bodies down the line. To my mind, Olympus has already demonstrated the desirable technical characteristics of a smaller sensor format, so there is good reason to believe that smaller than full frame sensors are here to stay. By extending the glass beyond the mount and into the body, and/or covering a smaller circle, Canon and Nikon are providing those same technical benefits to users of their smaller sensor cameras, namely sharp, extra wide angle in a compact package. Besides which, I'm much more concerned with the photos I couldn't take if I stayed away from the product, than I am with its unknown future upgrade path.
While the Olympus lens and 4/3rds system was intriguing, I felt that the 7-14mm wasn't worth more than double the price of the Canon for 2 extra mm at the wide end. It's also double the weight - making it impractical for use as an everyday lens, and negating the advantages of the E-1 body. So, I was pretty much down to the Canon or the Nikon (or the always available Waitsomemore).
At this point, I should say I'm platform agnostic. In the 80's I happily used Minolta equipment. In the 90's I bought some Nikon gear to use their 15mm prime lens. Basically, if it suits my purposes, I don't care what the label is.
Back to the lenses. The Nikon is more expensive and less wide, but it does have the continuous maximum apeture throughout the range. The Canon is wider, a tad lighter, and a tiny amount faster at the wide end. Both appear to be excellent choices, but I could not consider them independently of the cameras they would be mated to. Since I did not already own a digital body, it also came down to a decision between the Canon 20d & Nikon D70s. Here, the Canon wins for me on quality of sensor and a host of other details.
In practice, the lens is a joy to use. It's sharp. The zoom allows it to be as wide as you need it, which is an improvement over my previous favorite Minolta 20mm 2.8, though it does lack the depth of field scales which the Minolta has. The zoom also allows for keeping the lens mounted without switching as often, and that's important for keeping out dust. It's a very solidly built, quality instrument. Focus is fast if you're into that sort of thing, and nearly silent with the ultrasonic motor. The lens does not extend in length for zooming or focusing, though the front elements do move slightly inside the barrel. Mated to the 20d it's a tool that exceeds my previous film cameras in just about every way imaginable. I'm finally free to make the ultrawide photos that I want to make in the digital domain and the initial results have been outstanding.
If you're into ultrawide and want to go digital, the 20d with 10-22 is a fantastic setup. If you've already gone digital and want to try wide angle, (assuming your camera can use ef-s lenses) this is a true bargain - you get a 16mm, 20mm, 24mm, 28mm, and 35mm all rolled into one. It makes me positively giddy. Thank you, Canon!
As an x-ray tech I was laid-off a few years ago. My new job requires that I also serve as a Medical Assistant.. This little guide has been a life saver!!! A lot of my job requires following up on patient's medications and this little book has been great!!! Yeppers the letters are very tiny but that's what makes it a pocket-guide!!
We bought this Britax B-Agile after searching all brand and after reading lots of review. Even we are ready to pay much more for the best stroller for our first baby... we pick up this stroller and feel really happy we did.
It's light weight make it a winner. Excellent design and very good function
It should be the best stroller for the money
I've bought two of these reindeer outfit last Christmas and I plan to use them this year as well. They hold well on my car. The instruction does suggest not using it when traveling on highways. Often times I only go local, so I've never had any speed problem or lost antlers.
It's very easy to install as well. For the antlers, all I need to do is to place them on the window edges and for the nose I need to wire it on front logo.
On my Honda Accord coupe, the antlers would get loosen sometimes when I open the windows for pickups, so I need to pay extra attention when doing so. Yet that's mainly because there're only two doors so I don't have other choices to mount the antlers. If the vehicle is a 4 door, then I'd recommend mount the antlers on rear windows and avoid front windows which need to be open more often. That's what I did with my hubby's 4 door car and it still looks very cute.
I think they are made of sturdy materials and do resist water well. Sometimes they got soaked in heavy rains, but didn't lose shapes and dried up well. Overall, I'm enjoying the outfit so much and would recommend it to anyone.
Dan Brown cleverly orchestrated a cacophony of converging thoughts, insights, and feelings in this work. Around the time you hit the middle, you are inundated with your own self-reflections as you wrestle with an emerging moral dilemma. A wonderful read - if you are open-minded....and don't mind your own moral compass coming into question.
Great fodder for discussion among deep thinkers who dare to challenge traditional thinking.
