A thoroughly modern design that's optimized for select Canon EOS digital SLRs. Its angle of view is equivalent to a 96mm lens on a 35mm camera, with a floating optical system that can focus down to full life-size (1:1) magnification. Inner focusing, driven by a silent and powerful ring-type USM, means the lens' overall length never changes during focus. This lens is a wonderful multi-purpose lens that's equally at home shooting macro shots, portraits or available-light photos. Like all Canon EF-S Lenses, its use is restricted to the EOS 20D, EOS Digital Rebel and EOS Digital Rebel XT cameras.

The SVP Digital Camera Review

!±8± The SVP Digital Camera Review

By the age of digital imaging, almost no one (low water) to be involved divers with underwater photography. This review is a dress real camera for beginners. The Chinese, SVP Water Kit includes a digital camera system and waterproof case for less than $ 100. There are obvious limitations and we cover them in this report.

She does not expect professional results with the camera, but you'll be surprised with the versatility of this compact little to be fully satisfied. WithAll the features you would expect to find in the popular brand "point and shoot" cameras would be to fit this compact system easily in BCD pocket. The specifications are listed for our review comments. Because the factory provides the marketing brochures, we can not confirm or deny.

First of all, this camera before ... See instructions enclosed DVD that came with the camera. There are many functions and settings that you need to know this site before you on the waterUse the camera system. We have used many different brands and all settings seem to be some logical and some not-so-logical methods to do so. Like most "point and shoot" cameras, there is a delay between pressing the shutter button and the actual operation of the shutter. Once the operation of the camera and the features you are ready for the underwater part.

As every case, you need to keep your body clean and free of sand or gravel that might cause a loss. Since theMain seal is not really an O-ring, I was very careful to clean the surfaces with a cotton swab (qtip) and there are some O-ring grease on the surface as a thin film on the same estate. The seal is a kind of wedge shape, so it should provide a good pressure seal. The part is cleaner for all the little buttons you can change the camera settings underwater. We are in the best settings that we found when using the camera to get under the water.

If you say, theThe house is a good 15 meters or 33 meters, do not lie. Not that we were trying to flood the body or anything, but at 60 meters, the camera is not operational, because the pressure is to push the controls and the camera turns off. At 40 feet, you could get to work the camera, but do not change the settings. At 35 meters, the camera seems to work with all operating functions and settings well. For many divers, this is limiting, since most of the dives aredeeper than 35 meters. But keep in mind that in the end, red / yellow / orange spectrum is filtered over this depth.

The combination of camera and housing, well integrated and easy to use. With the clear plastic wrap, you can easily find the camera settings. Like most digital displays, certain angles are harder to see, but with the right angle and shading everything is visible on the screen by 2 inches. Although it is possible, the lens focal length from wideFor more corners, keep the wide-angle setting for diving in the whole process because of the water. Keep this in mind for all underwater photography, being close to the subject and use the widest angle possible, for best results.

To record still images, the camera was set to strobe, with each shot. This costs the batteries faster, but when the subject has more than 8 meters, it is better image and color. The best results were achieved our macro shots where we areCamera to 'close-up "and used the flash. When using the movie mode, you will be impressed with the sharpness of the images do not expect, however, that the high-quality audio. The case must be a large part of the sound as much of the underwater noise silencer to absorb. More than likely, you will be working with some background music in any case.

The color balance was a little 'off. We had the settings according to the instructions and the results that change the color balance a bit 'on the blue side for bestShots. This was not a problem for underwater shooting the greenish water has been removed. Most of the problems of color balance can be addressed in the editing phase.

The statement, 12.0 mega pixels is a bit 'tricky, because this is the "hardware interpolation," not the "resolution", which is 5.0 megapixels. All in all, we were not disappointed by the quality of the results of the best images. However, some of the shots were even with the built-in flash to shake.This means that the trigger to adjust the amount of light, so it is important to press the chamber and keep it as quiet as possible.

We have an 8 GB SD card, because we expected to take a lot of video and had plenty of space for two dives. We did not use the supplied USB cable, because we have a card reader to use our laptop and then again the memory of a portable hard drive. The power source operates on two AAA alkaline batteries, so there is a problem with the new batteries for eachdive. We did not use the "Voice Recorder" function, but from our experience of underwater video, would not be recommended in the underwater housing.

Now for the bottom line advice for this course: If you are going to take your underwater imaging seriously, save your money for a more complete system. This could be the perfect outfit for divers who want to share her experience diving with his friends and family. For less than $ 100 (prices range from $ 70-100), not including yourSD memory card or batteries, has a value. SVP cameras in some dive schools are marketed directly from importers and online interactive. The next "point and shoot 'clothing under water without an external flash will cost probably around $ 500. So, if you go on holiday and think with your own digital camera equipment for the flat water, which is the answer. Of course, for about $ 35 more than the dip, you can rent a camera with everything included. Sometimes theChoice is not easy, but there is much more to someone who has tested the SVP of white. This is a good camera and dress again for the video about the water and under water about 35 meters.

Autofocus vs. manual focus

!±8± Autofocus vs. manual focus

I asked this question many times by many people. What's better autofocus and manual focus?

And the answer is really simple and uncomplicated. The mode is the main focus is on a lot of external factors, especially in light conditions and the nature of the recordings. I will try to explain how these conditions affect the focus you choose.

Most DSLR is an exceptional six nine point auto focus feature and the results are quite good. But there is a driverHere. Autofocus works primarily seek to distinguish the differences. How about, for example, if the floor were dark back, then the focus to focus on any bright object in the foreground and back-ground. But what happens if there are any bright object in the ground limelight? The autofocus does not work in the situation. To work around this problem, many cameras use a system in which a small amount of light used to illuminate the terrain in the foreground when focus (you may have noticed himself, when shooting inlow light, the light in front of the camera usually illuminates the lens properly intermittent). This is not very effective and the auto focus may end up focusing on a point that is not your interest. In these circumstances it is better to perform a manual focus. I personally prefer manual focus in low light conditions.

Autofocus not good at extreme zoom. SO I prefer to use manual focus. Personally I prefer the manual anywhere, but autofocusworks well everywhere except the exceptions mentioned above. Therefore, the choice is yours, the focus is already mentioned with the drivers.

But there is a case in which I as mandatory auto focus. This is when you use continuous shooting mode. I use this mode for action photography such as sports photography. Continuous high-speed camera (some cameras can shoot at 16 frames per second) firing. So it's almost impossible to use the manual focus here. So I always use the setin these situations. But for all other conditions, which I personally prefer manual focus, because I think that gives me more control over the photos.

But the auto focus works well, except the above conditions, so that when you are with auto focus, deal with it, only the above mentioned guidelines in mind and keep your pictures will turn out well.
