Canon digital cameras can only use Canon Speedlite flash models with names ending in EX. If your Canon flash unit has a model name which ends with E or EZ or anything else then it will not work with any Canon digital EOS camera. for flash units manufactured by other makers, check its specifications to see if it supports “E-TTL flash metering.” If it does not, or only lists “Canon TTL flash metering” then it most likely will not work.

Before using any unfamiliar studio strobe or other non-dedicated flash unit with an EOS camera, we STRONGLY recommend that you determine its trigger circuit voltage. Excessive trigger circuit voltage can damage the shutter units and X-contacts of most modern 35mm SLR cameras. Please be aware of the following information: Trigger Circuit Voltage: The "trigger circuit" is the part of any electronic flash that detects the X-sync signal from the camera and then fires the flash.

The Sigma SD10 uses Sigma's exclusive SA lens mount, the same as used on Sigma's 35mm SLR cameras. There is a full array of lenses available, from 8mm Circular Fisheye to 800mm APO telephoto, including three 1:1 macro lenses; and zoom lenses from 10-20mm to 300-800mm. By the way the SD10 features a stainless steel camera mount , and all lenses for it feature metal lens mount.

You can’t. The sound you hear is the real thing. All Canon digital EOS cameras contain moving parts which click and clack when you take a photograph. They aren’t like mobile phones and consumer cameras which play simulated shutter release noises through tiny loudspeakers so that people know when the camera has taken a photo. There are two components which make up the characteristic sound of an SLR in operation.

Probably, but depending upon your camera's support for standard external flashes, it may require some persistence and some workarounds:

Very simply, it’s because it costs more to build a digital camera than a film camera given today’s technology. Technology is, however, changing at an incredible rate, and it’s just a matter of time before the two technologies are reversed when it comes to cost, just as CDs once cost considerably more than vinyl records. Canon have produced a number of digital cameras compatible with the EOS system over the years.

Recent Canon SLRs use a system called E-TTL to determine flash exposure. (Newer models use E-TTL II, which seems to be more robust.) E-TTL is praised by some for allowing very precise control over flash exposure when used properly, but it is slammed by others for being too sensitive to very small changes in the center of the image and requiring too much planning to get proper "automatic" exposure. There is probably some truth in both positions.

Any good still camera with S-Video will be okay. You will also need a video card with the S-Video / Composite input (for example Radeon 9200) or a USB adapter(for example Belkin F5U208).

Not really. In the years before introducing EOS autofocus cameras, Canon sold many manual-focus lenses for their SLR cameras. The majority of these lenses are of the FD type. Sadly, FD lenses cannot be used with EOS cameras. The lens mounts are of incompatible sizes and types. This is in contrast to Nikon - most Nikon manual-focus F-series lenses can be used with most Nikon autofocus cameras. Now it is possible to use adapter rings to attach FD lenses to EOS cameras.

There are two things that are important to keep in mind when shopping for lenses for an EOS digital camera, such as the EOS 10D, rather than an EOS film camera. First, EOS digitals are still not as cheap as film cameras, so don’t just try to find the cheapest lens you can. And if you’re going to be shelling out this much money for the camera body, buying the cheapest lens you can find is not merely false economy, it’s downright foolish, if you ask me.

This error condition is analogous to the “bC” error with film cameras. It’s most likely caused by using an incompatible lens or dirty lens contacts. Try a different lens and see if the camera works normally. Many older Sigma lenses in particular do not work with digital EOS cameras. Try also lightly cleaning the lens and camera metal contacts - this frequently clears up the condition.

You will need a female hot shoe to sub-mini phone accessory cord. The female hot shoe end is where the flash is placed. The sub-mini phone end plugs into the output of the MicroSync? receiver. This accessory cord is available from: Paramount Cords

Yes! Just so long as your camera records pictures in the "industry standard" .jpg (JPEG) file format. And even if your camera doesn't support .jpg (JPEG) image files, you can easily convert your pictures to the .jpg (JPEG) format using most any picture editing software and then print them with PrintSix?. But before ordering PrintSix? please double check to be sure your camera and/or photo editing software supports the .

Yes, but please note there is a limitation with Canon EF lenses. Because the aperture is electronic (instead of mechanical), the EF lenses do not allow you to close the aperture without being connected to a canon digital camera body. Despite this limitation, we've seen great footage coming out of EF lenses.

Many thanks to someone (sorry, I've lost the posting!) who passed on a tip about the Canon USA booklet, "Speedlite Reference Guide" (Chuck Westfall, 1991). This is an excellent little book and it contains some essential information which Canon have not bothered to tell the world in their instruction manuals. The booklet can be obtained from Canon USA, One Canon Plaza, Lake Success, NY 11042, USA; telephone +1-516-488 6700. They sent mine immediately and there was no charge.

Some cameras are designed for this, so you should check your manual. It's rare to find this feature in high quality digital cameras, but lower quality multifunction cameras with CMOS sensors sometimes offer this. See, for example, AipTek. If your camera doesn't already support some webcam features, you may still be able to do it if you have a video capture card (or USB device) of some kind, by connecting the video out from your camera to the video in on your PC.

The good news is, unless you are shooting close-up pictures of jewelry, you don't need an expensive camera to take good product shots. If you are shooting pictures for use on websites and not for print, you can get a good camera for less than $200. The quality of your images is going to depend much less on the sophistication of your camera and much more on your lighting and how well you operate the camera.

Unlike point and shoot digital cameras, Canon EOS digital cameras are SLRs, which means they use mirrors. The image sensor is situated behind the mirror, so no light reaches the image sensor normally but is instead deflected up into the viewfinder. When a picture is taken the mirror flips up out of the way, blacking out the viewfinder and letting light reach the image sensor.

The Digital Camera Poster Creator works with images from all digital cameras. It even works with scanned images or digital images from any other source.

Yes and no. Some older model flash units have discharge voltages in excess of 200 V DC across the camera's hot shoe. These units should not be used on the G cameras as they may damage the camera's circuitry. Check the voltage with a voltmeter before using it on your camera.

The answer depends on your personal needs and your budget. Memory cards are available in many sizes 8MB, 16MB, 32MB, 64MB, 128MB, 256MB and 512MB. The larger the card size, the more storage space and the greater the cost. One recommendation is to select a card that allows you to take images without having to worry about changing cards or downloading images very often (one of the advantages of digital photography). Among the most popular are those in 64MB, 128MB or 256MB sizes.

Several companies are offering point-and-shoot digital cameras with ring flashes and calling them digital dental cameras. These cameras do not function well because the camera has no way of controlling the amount of light the flash puts out. Every time you take a photograph, the amount of light necessary for a proper exposure is slightly different.

Most consumer grade ($300-$2000) digital cameras have either a fixed focal length wide angle lens, two times optical zoom (approximately 35-80mm lens, a three times zoom, up to five times or even 10 times zoom!) Some cameras in this class will use a Teleconverters, fish-eye converter, or wide angle converter lens to extend this range. A few cameras use a digital zoom, which electronically enhances the optical zoom.

Cause : You have modified the pictures or you have placed them in a folder other than the one the camera uses. Solution : If you have modified the pictures, most cameras will no longer be able to see the pictures. In the future do not modify the pictures if you need to see them again with the camera. If you placed them in the wrong folder, please put them in the folder you originally found them in. Most cameras will only use the folder they create to see the pictures.

Most external flashes have pivoting heads, which permit you to bounce the flash off the ceiling, further reducing the chance of red-eye and giving the scene a gentler, more natural illumination.

Probably not. The flash foot has to conform to the Contax contact pattern and TTL scheme. Your flash will work in manual mode. If it has an auto mode, it will also work on your G camera in that mode.

The lens is a 100 mm Macro (around $600) and the ring flash is a MR-14EX (around $499). You can also use a Sigma 105 mm Macro lens (around $359). Can't go wrong with Canon paper. I like Glossy. If I was sending a before and after to a referring doctor, I would print 8.5 x 11. I would arrange the images and text in Photoshop Elements and print in Landscape orientation.

Digital sensor technology is pretty complex. A lot goes on behind the scenes when we press that little button. This gives a good start in understanding how they work:

Yes, the Orbiculight has been tested with high-end digital systems. The Orbiculight is a flicker-free light source. You just be increase your exposure times rather than firing a strobe.
