Canon Portrait Lens On a Budget - How To Choose A Portrait Lens

!9# Canon Portrait Lens On a Budget - How To Choose A Portrait Lens

[if ]

Getting a good portrait lens is not difficult, but knowing which ones qualify is important. Before you go out and make a purchase, you should take a look into your camera bag to see if you may have a Canon portrait lens in there cleverly disguised as.. let's say a Macro lens or maybe a sports action lens.

The first issue is to determine what the qualifications of a good Canon portrait lens actually are. But in the process, keep in mind that you want to save money.

I hope this does not burst your bubble. I mean, photographers are kind of like fishermen and golfers. We are always under the impression that we need the next new camera or lens that comes out. Or, like my mother-in-law used to say, "If you don't have it, you need it." While the grass may be greener on the other side of the fence where your neighbor has a Canon EF 135mm f/2.0 portrait lens that she paid 00 for, it's possible that you can get by with something that you either already own or that costs just a tad bit less.

OK, real quick, the qualifications:

1. Image quality - this has to be really good. You do not want a lens that has poor image quality. After all, you will be shooting people, and most people are very vain about their appearance. It's not like taking a picture of a monkey or bear at the zoo. Those animals don't care what their picture looks like.

To find out whether the lens in question will qualify as a Canon portrait lens with respect to image quality, check some expert sites. But keep in mind that these guys are going to be very technical. You might just want to go to the Amazon or B & H Photo website and check user reviews. In that case, look for reviews from advanced amateurs or professionals. They will also be fairly reliable.

2. Focal length - Portraits can be taken with a lens that is as short as 50mm or as long as 300mm. Some of the pros use the extra long length to get the great bokeh, but normal portrait shooters use a lens of about 85mm to 135mm. The good news is that if you have an entry-level or mid-level digital SLR, you have what is known as a crop factor, which simply means that your camera multiplies the focal length of the lens by either 1.5 or 1.6 depending on the make of the camera. So if you have a 100mm lens, multiply it by the crop factor of, say 1.6, and you have an effective focal length of 160mm. And a 50mm lens becomes an effective focal length of 85mm. Of course, the shorter the focal length, the closer you will be to your subject. That's why a wide angle lens of 28mm will not be your best bet for a portrait lens.

3. Aperture - The aperture is really important. The wider the aperture, the better your chances for getting the nice blurry background that is desirable in this type of photography. You want a minimum of f/4.0 for longer length lenses, such as a 180mm lens, and at least an f/2.8 for the shorter lenses, such as 50mm. The larger the aperture, the better your background will be. But you also need a good sharp focus on the eyes because there is a very shallow depth of field with the wider apertures.

Generally, single focal length lenses are preferred for portraits, but that is not a hard and fast rule. Some photographers use their Canon 70-200 mm lens for this and are very happy with it.

OK, so there is a wide range of possibilities here. Going back to the first suggestion, look into your camera bag and see which, if any, of your current lenses fit the qualifications. If you still need to purchase a Canon portrait lens, proceed with patience. Getting a lens that can do two or three types of images is also a viable option.

One last thing. Third party lenses, like Sigma, Tamron, and Tokina are also great ways to save a few bucks. There are some excellent lenses made by these manufacturers, but make sure you check what the experts and others who have used them say in forums and online comment areas.

Canon D60 digital camera

!9# Canon D60 digital camera

Muskovac Nick, PPSA Palm Harbor, Florida wrote very interesting article about Canon `s D60 digital camera. His article was inspired by personal experience and observation.

Author is an active user of digital cameras by Canon. The first Canon D 30 was comparing the Canon D60, D30 with Mr. Muskovac place as the essential difference is that the D60 has many more pixels - 6.3 million pixels, which suggests the D30 with 3.25 million pixels.

He pointed out that the D60 is CMOS, whichconsumes less energy and allows the camera to take multiple pictures on a battery than most point-and-shoot cameras with no loss of image quality.

The most important technical data in Mr. Muskovacx `are:

Camera Body

Event Contact:

(1) Accessory shoe: X-sync contacts

(2) sync connector (threaded) on the bottom of the camera.

External Flash systemCompatibility: Compatible with E-TTL automatic synchronization.

In my opinion, the most important and functional specifications of the D60, which take all Canon EF (auto focus) lenses.

This was a very important aspect for me, since already Canon EOS EF lenses and the following equipment:

20 mm 2.8 28-135 IS 4.5/5.6

100 mm 2.8 macro 75-300 is 5.6

70-200mm2.8 1-400 is 5.6 2.8 300 mm

Using the camera in action, took a couple of shots andanalyzes the image quality. He used the Canon 100mm 2.8 macro lens. Then he says, "is the focal length of 160 mm mounted on the D60, an excellent macro lens. I use a twin macro flash, which I have for years with my EOS 1N. I shoot with manual mode, this flash with the Guide Number to measure the distance. The shutter speed is set the camera to 1 / 200 sec. I, f-stops vary depending on the distance from the plane of the butterfly imaginary film. The f-stop isF16 and F25 is generally between. If the distance from the subject over 1 1 / 2 feet, change the setting: ISO 100 to ISO 200 instead of opening the hood. In this way I could have a small opening and maintaining a good depth of field. With the D60 and 6.3 million pixels, I could make a very good print 10 x 15 cm with the largest storage mode of jpeg images. Figure 1 shows a Coolie Butterfly taken at ISO200, 1 / 200 sec, F22, and a distance of about 2Feet. "

When using the measurement on a green background of snow egrets, herons are overexposed. He then concludes that "the same applies, to a lesser extent, the use of measuring partial and center-weighted average center. To get the right exposure, the little egret, a stop exposure compensation -2 / 3 to -1 was used in evaluative metering modes to shoot. I have almost all my photos with evaluative metering. "

It pays attention to the numbering systems.We can choose: (1) continues. (2) Auto reset. In continuous mode, the numbering is continuous through the papers. Then he demonstrates that the Canon software assigns folder numbers. The photo with the next number in each folder related to the previous folder from the left, creating a continuous numbering of the images. The date / time is also permanently stored with each image. Convenient memory function allows images in folders in groups of 100, instead.

In the auto-resetNumber corresponds to 0001 every time a new card.

D60 file numbering only goes up to 9900 would have been nice to allow 100,000 images. Serious shooters more than 10,000 images a year.

Here's an example of how to work the numbers and the image folder:

Folder Range Image

IMG_0001 IMG_0100 CANON100 to

IMG_0101 IMG_0200 CANON101 to

IMG_0201 IMG_0300 CANON102 to

IMG_9801 IMG_9900 CANON198 to

CANON200IMG_0001 IMG_0100 by

IMG_0101 IMG_0200 CANON201 to

With pictures in different folders, duplicate image file names are identified and then be renamed.

The D60 is a beautiful 1.8-inch TFT color LCD, this allows us to review the images immediately.

Important to its comments regarding the battery life usually with 50% flash control mode is on, can usually result in 350-400 images on a fully charged battery. And he concludes: "The review ofImages do not use a significant amount of battery power. "

According to the author the following features of the D60, which I think are important:

1 D60, all Canon EF lenses.

2 Changing the ISO settings in mid-roll.

3 Check your image: immediately after exposure.

4 With a built-in 1.6x extender.

5 shoot 3 frames per second and up to eight consecutive images.

He is the D60 a good score. Above all, he is impressed with the imageQuality. According to him, "the camera has interchangeable electronic ability to focus long lenses and multiplies by a factor of 1.6 x. In general, it seems that the D60 is a camera
