chronicle of the Canon Wide Angle Lens - The Ef-S 10-22mm F 3.5-4.5 Usm

I have just received my new Canon Ef-S 10-22 ultra-wide angle lens. This is one of Canon's most favorite lens and is designed for the "crop sensor" series of Dslr. More on what a crop sensor is later. My first conception after a join of frames is "Wow, this is for real wide, it wraps colse to my block."

The request of the day is why do I need a 10-22mm wide angle lens. I already have a Ef-S 18-55 zoom that came with Canon X1i camera. So what am I going to do with that extra 8mm of width for a wide angle shot. That 8mm is like a football field when I am shooting a landscape in the distance (well maybe not quite a football field, but close).

Canon Ef Lens

There is a great need for those of us that shoot landscapes for a wide angle lens. As you might observation in my landscapes I tend to shoot very wide shots with mountains or red rocks in the foreground and the horizon in the distance. I have been shooting most of my landscapes at 18mm with my kit lens on the T1i. That means that I am shooting at 28.8mm in film 35mm size. This is because the T1i is a crop sensor camera with a factor 1.6x.

Now I have to illustrate the crop sensor stuff. Suffice to say that there are three ratios of crop sensors in the Canon line of cameras; full sensor, 1.3x, and 1.6x. This refers to the ratio of the sensor (the computer chip that sees the image and translates it to digital). The full sensor is the same size as the 35mm camera of years past. The two other ratios are, in effect, a subset of the full sensor and the 35mm film size. For practical purposes this means that the full sensor would see the whole football field, the 1.3x sensor would see inside the 20 yard lines and the 1.6 factor would capture inside the 30 yard lines. Now, you math majors out there do not hold me to the exact proportions, I am just trying to illustrate the concept.

Here is a list showing what Canon cameras have which sensor:

• Canon Eos 1Ds, Mark Ii and Ii (Full Frame)
• Canon Eos 5D and 5D, Mark Ii (Full Frame)
• Canon Eos 1D, Mark Iii,Iv (1.3x Crop Frame)
• Canon Digital Rebel, T1i,Xsi,Xs (1.6x Crop Frame)
• Canon Eos 20D,30D,40D,50D,7D (1.6x Crop Frame)

Now what does all this have to do with me wanting, needing, lusting after a 10-22mm wide angle? Now you know that this lens will fit on my camera (whew, that took a long time). You will also know that the 10mm, the widest of the wide angle, is for real a 16mm on my camera compared to how it looks on a full frame camera. That is still very good and will capture for real ranging views of those red rocks that I am so fond of.

What about the other characteristics of the lens? All the reviews I have read show it to be a very high potential "glass." Canon designates their top-of-the-line lenses with the letter "L" in the description. Although the Ef-S 10-22 f/3.5-4.5 does not carry the "L" designation, the use of three aspheric elements and one Sd element is a base characteristic of a potential lens. My first first shots with the lens left me with the impression of how clear and sharp it is.

This has potential visual parts and is not a "low-end, consumer type lens". Some pundits have suggested that if it had not been an Ef-S type lens, it might have received the "L" designation, but since it will not fit on a pro level Dslr (Eos 5D,1Ds series), Canon did not give it a "professional" L designation. In fact, no Ef-S lenses have the "L" designation to date.

Ef-S lenses, of course, are designed for use only with Aps-C (1.6x) sensor Canon Dslrs and will currently only physically mount on the Digital Rebel series, and Eos 20D,30D,40D,50D 7D. The Ef-S fabricate allows the rear element to be closer to the sensor then with Ef lenses, enhancing image quality, especially at the shortest focal lengths. The "S" in Ef-S means "short back focus" and now you know why.

There are many technical reasons that this lens is good for wide shots and landscapes. The reviews have shown that it is very sharp and very fast when auto focusing. On the negative side I will note that, if you use this lens when finding at a someone up close it will make them look like they are standing in the circus exhibit with the distorted mirrors. It is clearly designed for those shots that are as wide as all outdoors.

Canon 35mm f1.4 vs Sigma 30mm f1.4 arch to arch - DSLR FILM NOOB

Canon 35mm f1.4 vs Sigma 30mm f1.4 arch to arch - DSLR FILM NOOB Tube. 5.12 Mins.

www.dslrfilmnoob.com I often recommend the Sigma 30mm f1.4 as a good crop sensor camera lens for people on a budget. But how does it stack up against the Canon 35mm f1.4 lens. At around 00 to 00 new, the Canon 35mm f1.4 lens is a big investment, so much so, that I often recommend saving that money and buying 3 mid range primes instead. The Sigma 30mm f1.4 on the other hand runs about a 3rd the price at around 0. So is the price difference worth it? I think that depends on your mind set. The Canon 35mm f1.4 looked better (to me) in many of the shots as far as over all sharpness is concerned and the sigma 30mm f1.4 did have some slight vignetting in a few of the shots. But I guess the question remains, is the Canon 35mm f1.4 0 better then the sigma 30mm f1.4? I think you will probably have to vote with your dollar.

Canon's 50 mm f1.8 Ii is preponderant for legendary sharpness including ultra fast f1.8 optics. If whatever wants to have both the lightest and cheapest Ef lens, it will be obtainable from canon. It seems as it is made from cheap plastic as well as its lens mount. The lens make you feel as you have a cheap toy in your hand.

It is the lighted and shortest lens brought to you by canon. Many of you like me will be sure that the plastic lens mount is adequate for strength. In this lens, no length window exists. A micro motor drives the auto focus. It will be fine in good light and is useful for gently intelligent subject.

If you have both mark I and Mark Ii you can see where the contrast is. The sharpness of the 50mm f1.8 is dissimilar from zoom lens I used before and well I don't find any match in comparison with it. The lens 50 should not be flexible for zooming. On the other hand, it will be very useful when you will move by your feet. It is a fact that Dslr is equivalent of 80mm lens. With this lens you will be able to shoot any party or group because the joint weight of the rig is like a point.

When it is your only lens, it will not be recommended from me to hold the nifty 50mm. But, as beginner, you can start with this. If you want to allocation for purchasing it, I will advise you to buy as it does not make you feel any weight at the time of carrying. And you get it very useful when you will work with it. You can shoot indoors with this lens comfortably. You can shoot with it in low light location where flash is needless for the photograph. It will be convenient for a photographer who works in adverse condition. It is a prospective chance for the users who want to get a close to disposable lens. It starts experimenting as it has fast lens.

You shouldn't be worried of its build quality. The only fact, the optics are well fantastic. I don't think that it will break easily. You can throw it away if it breaks after a combine of years. You can replace it without feeling sorry.
