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.

That depends. Many third party lensmakers - Tamron, Sigma and Tokina being the big three - manufacture lenses specifically designed to fit Canon EOS cameras. These lenses will, of course, work fine with EOS cameras. The main caveat is the compatibility with the electronics detailed above. However, if you have a third-party lens which does not physically fit onto your EOS camera then you can obviously assume that the lens will not work with EOS cameras.

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.

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.

Why is it so complicated to get the exposure right on my pictures? (Why doesn't the camera just capture what my eye sees?)

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.

In addition to the aforementioned L series lenses most other Canon EF lenses fall into a number of broad categories. Note, however, that these are not official Canon-named categories. As far as Canon is concerned, EF lenses come in two categories - L and all the rest. Nonetheless these informal categories are useful to keep in mind when lens shopping. the bottom of the consumer line are the cheapies - ultra-low cost, low-quality, slow lenses with plastic mounts and no distance scales.

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.

This is a common misconception and is false. While Zeiss never supplied lenses for a Polaroid camera, they did produce the view/rangefinder assembly found on a few models (i.e. the 250, 350, 360, 450 and 180), and this is probably how the confusion came about. [Personally, I tend to feel that getting Zeiss to supply the view/rangefinder for certain high-end models was really as much of a marketing point than anything else, but...]

There is a mount converter from EOS to FD, but it is a MACRO converter only! That is to say, it does not allow the fitted FD-mount lens to focus to infinity. In addition, it does not work with cameras that do not have interchangeable focusing screens, and certain FD lenses might not fit! Ask Canon for the list of incompatible lenses before investing in an FD-macro setup. Available from Canon Professional Services ONLY, there is a 1.26x teleconverter for certain 200mm+ lenses (and the FD50-300/4.

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.

For Canon EF series lenses used with the EF25 extension tube and close up filters, see the Canon Close-up System booklet mentioned in section 1.1. This has a complete set of tables for all the current Canon EF lenses.

Yes, as long as the frame is still in good shape. We would not want you to put expensive lenses into a frame that will break in a few months!

Real" lenses use helical grooves to rack focus; the resistance you feel when you focus such a lens is the natural friction of the rotating barrels sliding through the lightly-greased grooves. That smooth friction, alas, plays havoc with autofocus systems which all consumer cameras must have, so goes the conventional wisdom; strong and battery-draining motors are needed to spin such barrels, and they can't obtain the fast focus response that's so useful in optimizing autofocus algorithms.

Disable the autofocus control whenever it could be fooled into focusing on something other than your subject. For example, if your subject walks behind a foreground tree, the autofocus will re-focus on the tree, leaving the subject soft when he or she emerges on the other side. To prevent this, use autofocus to lock onto the subject; then disable it so that it ignores the tree.

Not directly. There are adapters and combined teleconverters/adapters to mount Minolta SR lenses on Minolta AF cameras. However, even the simple adapters contain optical elements to allow the lens to focus to infinity. These have a small teleconverter effect (ca. 1.1x) and also have a negative impact on image quality. Of course, they also will not convert your MF lens to a AF lens, and you have to use stop-down metering because the aperture is also manual.

The patented PhotoMed flash atachment is designed to balance the light from the camera's built-in flash and yield an evenly illuminated field, regardless of the type of view or subject. By using the built-in flash, we can allow the camera to control the exposure (the amount of light) and the attachment redirects the light from the flash and balances it across the field.

Yes. EDIUS NX Express will support capture from and output to JVC and Canon HD devices via the IEEE 1394 interface. This includes full editing support for progressive video, including 24p and 24F. EDIUS NX Express is responsible for processing video overlay to the PC monitor via DMA, and video and audio output to external monitors with realtime line scaling.

Advanced Network IP Cameras utilize CS-mount lenses, which can accommodate a variety of specialized lenses, such as wide-angle, fish-eye or telephoto lenses. Note that MegaPixel cameras need special MegaPixel lens to take true advantage of their quality

Yes! and this will save you some money in the short term. You need to buy either a web enabled capture card to go into a PC, one or more Video converters that will convert the analog video into IP or a stand-alone NVR / DVR. Doing this will remove a piece of obsolete hardware and extend the functionality of your system for a few hundred pounds.

The are no rechargeable 2CR5s at present. A NiCad of that size would not have enough power to operate the camera for much more than about 1 roll of film, not even that if you use flash. There are rechargeable Li cells on the market with much higher capacity than NiCad cells (3 or 4 times as much), but they are not yet available in a 2CR5 package. Only the EOS-1 has the capability of using AA cells, which are available in rechargeable form.

Traditional film and digital formats may be used to take pictures for an application. There are considerations with either option. Although disposable cameras are convenient, the lack of an autofocus causes some close-up pictures to be blurry. Additionally, digital cameras with low resolution often produce close-up pictures of poor quality. As a rule of thumb, film cameras should have an autofocus and digital cameras should be 3 mega pixel or greater.

No. Not all artists used lenses, nor did a given artist always use a lens for all their paintings, nor did a given artist use a lens for all aspects of a given painting. An artist who did use a lens would have used it as a tool when it made their work easier, but would not have used it when it didn't provide an advantage.

Two reasons mainly: 1. The Rebel weighs only 13 oz (368.54 grams) with film, batteries and 28-80 zoom lens. 2. The camera quality at this price point is astonishing. The lower the weight, the more control you have and the less movement. Other 35 mm cameras may be used as long as they have auto wind and electric shutter release. We can custom configure for other types of cameras. Canon has come out with a 6+ Digital Camera on the Rebel body. Both cameras can be used on the same aerial system.

Our cameras support any C-Mount based lens. You can also order cameras with either CS-Mount or microlens mount. In video mode you can use the Start Of Frame (SOF) signal that is generated by the camera to synchronize a strobe. This pulse is generated at the end of the previous frame prior to exposing the next frame. In snapshot mode you can use the strobe output of the camera.

It is customary for a manufacturer to include a recommended replacement schedule for its products in the product package inserts, fitting guide booklets, and in some cases on the packaging itself. Such recommendations provide a reference point for those eye care professionals who are looking for such information.

Wherever they happen to be, I guess. General amateur-level models can be found at yard sales, flea markets, thrift stores, and the like. Your local full-service camera store may have some around. Many professional Polaroid camera models are still in high demand, so many camera stores will try to make them available. Want to try mail-order? Pick up a copy of Shutterbug magazine and peruse the ads-- you'll find a few old Polaroids hidden here and there.
