I have just obtained my new Canon EF-S ten-22 ultra-vast angle lens. This is 1 of Canon's most well-liked lens and is developed for the "crop sensor" series of DSLR. A lot more on what randy jackson recent a crop sensor is later. My very first thought following a few of frames is "Wow, this is genuinely extensive, it wraps around my block."

The question of the day is why do I need a 10-22mm wide angle lens. I by now have a EF-S eighteen-fifty five zoom that arrived with Canon X1i camera. So what am I likely 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 (properly maybe not very a football area, but close).

There is a fantastic require for those of us that shoot landscapes for a broad angle lens. As you may well notice in my landscapes I tend to shoot quite extensive 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 signifies that I am shooting at 28.8mm in movie 35mm size. This is due to the fact the T1i is a crop sensor camera with a aspect one.6x.

Now I have to clarify 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 laptop or computer chip that sees the image and translates it to electronic). The entire sensor is the identical measurement as the 35mm camera of many years prior. The two other ratios are, in result, a subset of the entire sensor and the 35mm film size. For useful reasons this means that the total sensor would see the total soccer discipline, the 1.3x sensor would see within the 20 lawn lines and the one.6 factor would capture inside of the 30 yard lines. Now, you math majors out there do not hold me to the precise proportions, I am just making an attempt to illustrate the idea.

Right here is a list demonstrating what Canon cameras have which sensor:

Canon EOS 1Ds, Mark II and II (Total Frame)
Canon EOS 5D and 5D, Mark II (Complete Body)
Canon EOS 1D, Mark III,IV (1.3x Crop Frame)
Canon Electronic Rebel, T1i,XSi,XS (one.6x Crop Frame)
Canon EOS 20D,30D,40D,50D,7D (one.6x Crop Frame)

Now what does all this have to do with me wanting, needing, lusting right after a ten-22mm vast angle? Now you know that this lens will fit on my camera (whew, that took a lengthy time). You will also know that the 10mm, the widest of the wide angle, is truly a 16mm on my digicam compared to how it appears on a complete body digicam. That is still really good and will seize genuinely ranging views of those red rocks that I am so fond of.

What about the other traits of the lens? All the critiques I have read demonstrate it to be a quite substantial high quality "glass." Canon designates their prime-of-the-line lenses with the letter "L" in the description. Despite the fact that the EF-S ten-22 f/three.5-4.five does not carry the "L" designation, the use of 3 aspheric factors and a single SD aspect is a frequent characteristic of a high quality lens. My very first first shots with the lens left me with the impression of how obvious and sharp it is.

This has good quality optical areas and is not a "very low-end, customer kind lens". Some pundits have proposed that if it had not been an EF-S sort lens, it may well have received the "L" designation, but given that it will not match on a professional amount DSLR (EOS 5D,1Ds sequence), Canon did not give it a "professional" L designation. In simple fact, no EF-S lenses have the "L" designation to date.

EF-S lenses, of program, are intended for use only with APS-C (1.6x) sensor Canon DSLRs and will at the moment only physically mount on the Electronic Rebel series, and EOS 20D,30D,40D,50D 7D. The EF-S design and style allows the rear factor to be nearer to the sensor then with EF lenses, bettering image top quality, especially at the shortest focal lengths. The "S" in EF-S implies "short back focus" and now you know why.

There are many technical factors that this lens is excellent for vast shots and landscapes. The reviews have proven that it is really sharp and really fast when auto concentrating. On the adverse aspect I will be aware that, if you use this lens when searching at a man or woman up shut it will make them seem like they are standing in the circus exhibit with the distorted mirrors. It is evidently intended for people pictures that are as vast as all outdoors.
