with buying a camera there are a lot of things to consider, so this question really can’t be asked without asking many more questions first. Here are some of them:

If you can afford a digital SLR then I highly recomend you get one, if not, any second hand cheap film camera body, preferably Canon or Nikon will do just fine. I used to use an old Canon EOS 1000FN. Canon & Nikon are preferable because should you want to move forward in this area of photography you'll end up wanting to use more and better lenses. Canon & Nikon are the current clear leaders in high quality lenses and are the choice of the vast majority of professional photographers.

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.

Although it seems no new ones had been manufactured by anyone for some years, very recently one has come on the market with what the manufacturer says is a revised optical design. I don't have any experience with this particular one, but you can find information about it at www.camera-lucida.com/.

If you read the discussion in the section on Scientific and Technical Questions you will see that a camera obscura is something to make, not something to buy, since all that is needed is a lens (or concave mirror) and some cloth to minimize extraneous light. Several years ago my daughter Amelia Falco, now an architect in New York, designed a portable camera obscura that is small enough to travel as checked luggage.

You will need the CLA-4 Conversion Lens Adapter. It provides a 55mm mounting thread for a 55mm filter or conversion lens. This can be purchased through the Olympus Emporium or by phone at 1-800-201-7766.

Machine vision optics should be mounted firmly but should not be stressed by excessive force. Do not rely on the camera C-mount thread to support heavy lenses. Either mount the lens and let the camera be supported by the lens, or provide support for both. Avoid over-tightening lens mounting clamps.

Yes, you can. Our screw in filters ( except for the the WID types ), are double threaded and can be screwed together. Stacking filters can create different effects and bring out your creativity. The only caution is that as you put more filters on the lens you can create vignetting or the cutting off of the corners of your picture. This can happen more with wide angle lenses. We do not make every filter for this purpose.

The Canon D60 with a Canon 70 - 200 mm f/2.8L USM lens. The camera captures 6.3 megapixels and allows us to print poster size images. The lens is one of the best in its class and the quality shows through to the images.

Choosing a suitable lens for your security camera, you need first to determine how far you want to monitor the scene. A 4mm lens will give a 72 degree visual angle of view for a person's face detail in about 30 feet. This will be adequate for most home or small office surveillance system. Based on this calculation, a 8mm lens will give a 40 degree visual angle and zoom in 2 times of the view in the same distance.

No, sorry. I am not a photographer myself nor do I own a scanner. Please ask your fellow photographers on Airliners.net. Find a photographer whose photos you think are of high quality and use the "Contact" link beside each photo.

Shop around. I like using pricegrabber to get prices from a large number of retailers at once. Pay careful attention to the merchant ratings column! Also check reselleratings.com. FWIW, I've noticed that Canoga Camera tends to have very competitive prices on Canon lenses. B & H Photo seems to be well liked be camera by camera aficionados for their good prices and good return policies.

The features that make a good camera for product photography are not necessarily the features that are important for other types of photography like portraits or everyday family photos. That's not to say that the camera you choose for product photography won't work well for other uses, but you may weight the relative importance of the various features differently.

First of all, DO NOT use Q-tips or any other product similar. The fine strands of cotton can scratch the lens surface. It is recommended that you purchase a camera cleaning kit. It is a good investment to keep your camera looking and taking pictures like new. ednote: one of the best investments one can make is to get a skylight or uv filter (if possible), and just keep it on all the time. If you mess up the filter, you can always replace it.

From our experience with our past customers, we recommend a lens of 35mm. The larger the lens the wider the picture and the farther away your pictures will be. In addition, we do not recommend you bring a telephoto lens camera as it will not give you best scenic picture quality.

The strongest advantage of this tool is that canned files are not needed. You can calibrate any lens you own quite easily. It might though be a nice idea to collect calibration files. If the demand among our users is high – we will set up such a service based on a user community.

A1: Fixed lens cameras have a set field of view and cannot be manipulated to produce a wider or narrower angle. These are generally found as 3.6mm, 4.3mm, 8mm, 12mm, etc.. The higher the number of the focal length, the more telephoto the effect. *However- this has nothing to do with the actual size of the lens itself. You can obtain a 3.6mm lens which can range in physical size from 1mm (on a micro pinhole type camera) to the size of a soda can (for much larger security type cameras).

Yes, provided the lens is mechanically and optically matched to the output area of the image intensifier.

Yes, Siemens offers a variety of imaging units where the individual components are matched to each other providing optimum image quality. On request, special lenses for specific applications are available.

StockerYale understands the wide range of applications in which our light sources are used and provides an easy interface to as many microscopes and camera lenses as possible. We provide reference charts to cross our adapters to most standard microscopes. If what you are looking for is not listed, contact our Sales Department. They will be able to provide you with an appropriate solution.

We recommend a lens of around 35mm. This approximates the field of view of the human eye. As the lens becomes progressively wider the picture will appear further away. Conversely, a telephoto lens narrows field of view and is usually not what you want in your scenic, aerial photograph.

A typical highway lane is about 3m wide. To see the full width of a four lane highway you will want a viewing width of about 50 feet. For the distance behind you, you will want to see at least 10 car lenghts in order to make safe lane changes. If we use a car lenght of 3m for the calculation, you will want to see an area of 15m wide at 30m back. All camera angles will suffice for back-up or rear-view systems. The width at 2m back should be wider than the width of the vehicle.

The lens that the cameras come with as standard are 3.6mm. We have found that this lens is ideal for most applications. We do stock other lenses as accessories No the one housings doesit all. You are supplied with x1 clip lock industrial velcro in both the Xtreme and XtremePlus kits. You'll notice that you can purchase more clip lock individually from the products section

Cameras are permitted on board and recommended. We have found through guest comments that a 35mm with ASA 400 or higher with a wide-angle lens works good. Our tours offer some of the most unique photo-taking opportunities anywhere on the planet. We have disposable cameras for sale in our logo shop. Your pilot will create a video of your actual flight utilizing our five-camera system which includes a cabin camera, side and nose cameras and a unique tail camera.

If you want to see, touch, feel and physically pick up your camera, I strongly recommend an upscale camera store in your city. They are more likely to have what you need in stock, they are much more knowledgeable, and they give far better service than the consumer electronics giants. Surprisingly enough, I've found prices to be a bit lower than in the major consumer electronics chains.

All consumer 3D cameras are capable of taking excellent consumer 3D photographs. While a larger number of lens on a camera gives a lenticular print a wider angle of view of the 3D effect, as in all facets of photography, the quality of a 3D photograph is more determined by the skill of the photographer than the equipment used. It must be remembered that a 3D camera requires twice the amount of film as a regular camera in order to create a single 3D photograph.

The advantages of wireless camera are that (a) it is convenient to be installed in those locations where wiring is difficult, if not impossible; (b) it can be moved to different locations easily, as often as you like; (c) it can be hidden inside a moving object like inside your cloth, cap, briefcase or carrying bag etc. The disadvantages are: (a) video stream may be disturbed or influenced by other moving objects or other strong radio frequencies. A wired camera is more stable in this respect.
