What is the best Canon lens wedding?

Posted: 30 Jun 2011 01:20 PM PDT

Choosing the best wedding lens for Canon DSLR camera can be a rather arduous task, because there are quite a few different opinions to consider, and variables. However, there is not a difficult decision when you consider a few simple factors.

To select the best wedding lens is right for you, you need to decide if you are willing to pay more than $ 1,000 for a professional L-series Canon lens to spend.The best weddings are all Canon lenses over the $ 1,000 mark, but fortunately there are cheaper alternatives, such as the Canon EFS 17-85mm F4-5.6 IS zoom lens, which is only the Canon's APS-C, as was Rebel series. Just above the $ 1,000 mark, a brilliant series of lenses available, such as 24-70mm F2.8 L, which is the most popular wedding Canon lens at a distance.

AnotherFactor to consider is whether you want to use a single camera or multiple cameras for the wedding. Many photographers use cameras instead of two housing swap lenses all the time. Other photographers prefer one body and one lens for the entire wedding. For a single lens solution, the Canon 24-105mm F4 offers a wide-angle to mid-range zoom function, which most of the wedding photography should cover the focal range.Other photographers with two bodies (or two photographers) and prefers a combination of lenses. In this case, a combination of 24-70mm F2.8 and F2.8 70-200mm IS offers the perfect solution.

A few photographers prefer fixed lens solutions that provide better image quality, but limits the flexibility -. It therefore has an influence on the style of the photographer with a fixed focal length lens fans prefer the 24 mm F1.4 L, 50mm F1.2 L, 0.2 L F1 85 mm and 135 mm F2.0 L orany combination of these. These lenses are often professionals with years of experience, who developed a particular style of wedding photography.

The single objective lens that works well as a wedding-General is the Canon 24-70mm F2.8 L, with the new 24-105mm F4.0 L as a strongContender, but if you still are not sure to read reports on all the options before buying.

Revision of the wide-angle Canon – EF-S 10-22mm F 3.5-4.5 USM

Posted: 29 Jun 2011 01:00 PM PDT

Canon EF-S lens

I just got my new Canon EF-S 10-22 including ultra-wide angle lens. This is one of the most popular Canon lenses and is designed for the "sensor crop" DSLR series. More about what is a sensor picked up later. My first thought after a couple of frames, "Wow, it's really wide, wrapped around my block."

The question of the day is why I need a 10-22mm wide angle. I have an EF-S 18-55 zoom, the Canon came withX1i camera. So, what should I do with that width 8mm more to make a long shot. 8mm is like a football field, if I shoot a landscape in the distance (Well, maybe not quite a football field, but almost).

It 'a great need for those of us who photographed landscapes for a wide-angle lens. As you can see in my landscapes, I tend to get very large images of mountains and red rocks in the foreground and the horizon in the shooting distance. I have most of my shotsLandscapes in with my 18mm lens kit on T1i. This means that I shoot 28.8 mm in 35 mm film format. This is because T1i is a sensor camera with a 1.6x crop factor.

Now I have to explain things collection sensor. Suffice it to say that there are three sensors crop conditions in the range of Canon cameras, full-sensor, 1.3x, 1.6x and. This refers to the relationship between the sensor (the computer chip, which sees the image and translates it into digital). The entire sensor is the sameSize as the 35 mm camera in recent years. The other two reports, in fact, a subset of the entire sensor and 35 mm film format. For practical purposes this means that the sensor will complete the entire football field to see the 1.3x sensor inside the 20 yard lines would be seen and the 1.6 factor was recognized by 30 yard lines. Well, math majors out there for me not to keep the proportions correct, I'm just trying to illustrate the concept.

Here is a list showing what CanonCameras, sensors:

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 (1.6 x crop frame)
Canon EOS 20D, 30D, 40D, 50D, 7D (1.6 x crop frame)

Well, what he wants to do with me, need, lust after a 10-22mm wide angle? Now you know that this lens will fit my camera (phew, that took a long time). They also know that the 10mm, the widest of wide angle is really a 16mm compared to my camera as it looks on a full frame camera. That is still very good and is really starting to understand view of red rocks, I like Sun

What about the other properties of the lens? All the reviews I've read, show very high "glass". Quality Canon calls its top-of-the-line lenses with the letter "L" in the description. Although the> Do not carry EF-S 10-22 f/3.5-4.5 "L" is the use of three aspherical elements and an SD-element is a common feature of a high quality lens. My first shots with the lens I first has allowed the impression of how clear and crisp.

This has the quality of optical parts and is not a "low-end consumer-the type of objective." Some experts have suggested that if there is an EF-S was the kind, could have obtained the name " L ", butas is the case on a pro-SLR (EOS 5D, 1Ds series) in shape, Canon does not have it "professional" L-label. In fact, no EF-S lenses in the designation "L" to this day.

EF-S are, of course, only for use with APS-C designed (1.6) sensor Canon digital SLRs and is currently only physically Series Digital Rebel and EOS 20D mounted, 30D, 40D, 50D 7D . The EF-S design allows the rear element, then approaches the sensorEF lenses, which improve the image quality, especially at the minimum focal length. 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 angle shots and landscapes. Evaluations have shown that it is very strong and very fast when the auto focus. On the negative side, I'll do that if you have this lens, if you use a person close look as if they were standing in the circusShows the distorted mirror. And 'only for the recordings, which are designed as big as all outdoors.

Canon EF-S lens

Batteries are the lifeblood of the digital cameras. Without batteries, the camera is no longer a toy. If your camera's battery lasts long, it can be assumed that the camera for a longer period. As the objective, the batteries are another important accessory of the camera that have different types and each have different composition and longevity. You can choose from one of them depending on the needs and requirements. Apartthe purchase of batteries is longer, you can also take some precautions to help move the battery for long periods of time.

This digital camera accessories play an important role and helps in proper functioning of the camera.

If you opt for one of these packets are then saved in any case a good amount of money.

Based on the composition of the batteries are again divided into different types. After the materials used in them,divided into four types, namely, lithium batteries, nickel-metal hydride batteries, nickel-cadmium and alkaline batteries. These four types differ in composition and in their working hours. Lithium batteries are more expensive, but they are also the best among all. Compared to the other, lithium may have higher and better life in the cold.

Before you buy batteries, you must check the compatibilitywith the camera as a machine to support several different types of batteries.

Canon EF-S lens

Canon lens range can be a bit 'daunting for any new SLR or DSLR camera owners. The main reason is probably the fact that Canon offers more than 60 goals for its range of SLR cameras and DSLRs. This lens line-up includes Primes, zoom, tilt & shift, macro, wide angle, telephoto and telephoto lenses.

Canon introduces Although many types of lenses,EF line, is the most popular is because these lenses with EF bayonet fit all Canon SLRs and DSLRs. Besides this, Canon also makes the EF-S lens range, the distance you live in a consumer Canon APS-C CMOS like the Rebel series. The EF-S cameras can only APS-C used, but these cameras can also use regular EF lenses. Each Canon EF canclassified into the following classes:

Prime (fixed) lenses

Ultra Wide – Primes usually with a focal length of 20 mm or less like EF14mm f/2.8L II USM. Used primarily for landscape photography.
Wide – First between 20 and 50 mm 1.4 L USM EF35mm like. Used primarily for landscape photography.
Standard & Telephoto – Primes between 50 and 100mm, as the brilliant EF85mm F1.2L II USM. Ideal for portraits.

EF-S
Lenses with a special holder, with the only Canon's APS-C sensor cameras like the Rebel series can be used. The cameras with APS-C has a 1.6-foldMultiplier effect on the normal EF lens, hence the need for the lenses, such as the EF-S 10-22mm f/3.5-4.5 USM, which is useful for landscape photography with the Rebel series.

Macro Lenses
Lens to macro photography can be used as EF180mm f/3.5L Macro USM.

Essential information on Objectives

Posted: 26 Jun 2011 09:00 AM PDT

As we know, there is no camera that can perform in all types of shooting situations goes the same for targets. Each camera has its own individuality and compared with the individual components of other benefits and disadvantages. By understanding more about how the camera lens separated from each other, you get to know how to apply the right camera for the conditions and requirements.

The selection of Canon lenses for digital SLR can be verypleasant and stimulating. Canon offers an extensive collection of lenses for both the amateur and the specialist. The purchase of a lens is an important process and procedure, as it would be to implement a new order your kit photography, but you want to make sure that your purchase is intelligent.

Most 35mm SLR on the market have an "objective standard". Objective standards now refer to a lens with a focal length of 50mm and isthe format in which an enormous amount of respect people around what we usually see with my own eyes. As such, 50 mm lens is still very well liked by all the photographers. Normally 50mm lens has a maximum aperture of F1.8. There are also faster lens with the largest opening of F1.4 and F1.2 well. To establish these goals faster to wear for the function and quality.

To observe any other obsession, is to make all SLR / DSLR cameras are compatible goals. Move the lenses can be performed smoothly and is different for the installation of the camera. The warmest support for most cameras today is the bayonet. In general, to change the lens with a bayonet, for the completion of a lens to a desk near the landslide then simply rotate the lens of 45 degrees clockwise to the inclusion of another goal, simply set the objectively by brand camera and camcorder > Lens and turn the lens counter-clockwise 45 degrees.

The talent of different lenses SLR / DSLR is really one of the main reasons for the vision and ease of use compared to other cameras in the picture. Therefore, a camera with a conventional lens would not be able to use the camera to make you better. Typically, most people think photographers get or have got another two lenses in the class of wide-angle lens and tele> Lens.

Canon lenses have a ring of focus, the user can focus the lens itself, and a control that users want auto focus or manual focus, such as how to focus. Latest Canon lenses are optical image stabilization, which allows the photographer to the stabilizer on or off and pick up different ways to stabilize the different types of photography, one for normal use and one for panning. Similarly, the lensesfocal distance has a switch to limit the photographer's focal length, can help, auto-focus time.

Canon EF lenses, which stands for "Electro-Focus" are. were introduced in 1987 on Canon film lenses. They are well coordinated with all the latest versions of Canon Digital SRLs. Other types of lenses Canon EF-S. EF-S only a couple of CanonCameras. The S stands for "short back-focus" and means that a portion of the lens closer to the sensor. Full-frame SLR like the 5D does not work with EF-S lenses because the style is slightly different bracket.

L-series lenses of Canon professional series lenses. The lenses focus very quickly and are often characterized by a high aperture, usually up to 2.8, so that they work well in low light conditions. Canon introduces the L SeriesLenses in white instead of black, as they say, that these lenses reduces the heat of the sun. L-Series only with a bayonet EF, not EF-S mount.

Canon EF-S 10-22mm F/3.5-4.5 USM Ultra-Wide Angle Lens

Posted: 25 Jun 2011 08:40 AM PDT

Canon EF-S lens

The Canon EF-S 10-22mm f/3.5-4.5 USM ultra wide-angle focal length is the largest Canon may, in its current EF / EF-S series of lenses. Wide an understatement. A lens 10mm APS-C size sensor camera would be the same equivalent field of view would be a 16 mm lens when used on a 35mm SLR or full frame DSLR. The 10-22 is the camera is raised to a 1.6 x 16-35mm lens.

For someTime has a real wide angle lens and not by photographers with an APS-C size sensor of the Canon camera. The next target will be a 14mm prime, but probably not within the average user. The next most likely option would be the Canon 16-35mm or 17-55mm zoom. Even then the equivalent field of view would be only about 26mm. Insert the 10-22.

Wide-angle lensesin different niches photo of inestimable value. You have to really prove their value in landscape photography in particular. No other class has the ability of the lens, the magnificent view of Mother Nature in order to understand better. You can see from dawn to sunset. No other set of lenses makes the picture less "stuff" to grasp. They are also used in both architectural photography, which shine in the detection of internal and external. Real estate agent fall in love with theAbility to show all internal house in one shot. Wide-angle lenses can also be very useful for photographers seek out the creative side of the record. The natural distortion with the wide field of view involved in creating some very unusual changes of perspective in everyday objects.

First, note the Canon EF-S 10-22mm lens is very well done. It does not feel "cheap" which is sometimes found in some other Canon lenses.The attention and the removal of the controls work properly. The lens focuses reached fairly quickly, and also silent thanks to the use of a ring-type USM focus motor. You may also find that the lens does not rotate during focusing or an extension or when adjusting the focal length. This is important because you can use a circular polarizer with this objective, even if you can see a slight vignetting, if you do not use, choose a slim polarizer. In most cases this should not beProblem.

I was rather surprised by the overall image quality of the EF-S 10-22. For most images are sharp and clear on most of the zoom range. There is a remarkably small amount of blur to 11mm. Makes it clear, though not offensive to 10mm. Center sharpness remains constant during the filming open or locked down, although it is the least amount of blur in the corners at all focal length lensArea.

I also expected the distortion is a problem with this objective, as for many other wide-angle lenses, but was never really that clear. There is a small amount of barrel distortion at wide angle, usually 10mm. There are even less pincushion distortion at 22mm. 12mm-20mm, there is very little distortion of any kind, this is very unusual for a wide angle lens. Equally surprising, chromatic aberration was not a problem. There was a lackCA obvious to 22mm. At 10mm, which was the smallest amount that was found could easily be cleaned with Photoshop.

Flare can be a problem with wide-angle lenses, the physical structure of the lens. With a field of view that exceeds 107 degrees at 10mm, it is likely that a certain degree of flare from the sun or other light sources are. The EF-S 10-22 does a good job in controlling lens flare, but for best results ever, use the EW-83EHood, which includes, unfortunately, not only for their Glass Canon "L" quality.

Overall this is an impressive wide-angle lens. The EF-S 10-22mm would be consistent with most other Canon glass on top, and professional quality of the final optical performance. One of the drawbacks I can find is only apparent leakiness of the time, and perhaps also the lack of a hood and carrying case included. In all honesty, the Canon EF-SF/3.5-4.5 USM 10-22mm ultra wide-angle should be an "L". I recommend it for every request, wide-angle photography.
