Re: canon

It really depends on what kind of photography you want to do.
I own both of those bodies, and the 5D is great for landscapes, portraits, and other artsy stuff.
However, the 3 frames per second doesnt compare to the 5FPS of the 30D, so if you're shooting sports, the 5D will do better.
Also, 5D is better for wide angle shots.

If you do decide on the 30D, again, lens choice really depends on what kind of shooting you plan on doing.

How to mount 67mm thread lens to t4i body only canon

One side of the reverse adapter has a 67mm thread, the other side has a lens mount. Mount it to the camera body as if it were a lens. Bear in mind that it's intended to screw onto the front of a lens and then mounted onto a camera to put the lens onto the camera in a "backward" position.

Will this lens work with a Canon 5d mkii?

Quantaray makes their lenses with a variety of camera mounts. A lens with a Nikon mount, for example, will not work on a Canon body. As long as you get the lens with a Canon mount, it will work with the 5D MKII.

Why does the camera say error 99 when i put lense on? camera works fine with other lense. we have a cannon 30d.

The Quantaray lens is not compatible electronic wise with your Canon. It is indeed made to fit Canon, but the lens is a bit outdated compared to the relatively new Canon.

Quantaray lenses were sold by Ritz Camera (also Wolf Camera). You would want to take it in to the and see if it can be sent out and re-chiped, which will allow it to work with the newer Canon cameras.

Not all lenses can be re-chiped. You may just have to purchase a new lens.

I have my Canon 30D set to manual but cannot change the f stop to anything below f/4.0. This lens should go to f/2.8.

Your camera body probably needs a firmware update to enable it to recognise the lens properly. The latest 1.0.6 firmware adds EXIF data for a number of lenses including yours to the camera. At the very least, you'll need to ensure that you have the latest firmware in order to eliminate it as a potential cause of your fault.

Will this Lens fit the Canon DSLR 1000D

Yes, it will fit Canon 1000D.
But I'll recommend you to try lens in a shop before buying - picture quality can be low.

I want a nature camera

First, to answer your lens question, 400mm is unlikely to be adequate. On a digital camera this is going to give only 6x magnification. Some nature subjects will require much more than that.

Also, do not need a fully featured 'pro' camera. These have features which you may not want. Look at lenses first, and let that dictate the camera.

It rather depends on your intended subject matter, but in general for nature photography (I presume you are thinking of vertebrate animals, rather than plants or insects.) you require very long focal length lenses. This is because wild animals are very difficult to approach, and many are comparatively small as well. As an example, you may only be able to get within 30ft of a heron however well you are hidden, and for a bird that size at that distance a 400mm lens will just be big enough. Just.

As a rule you want to fill the frame. So to work out what focal length you need you need to work out the size of the image in the camera. This is not difficult to work out, as the magnification is only the ratio of the subject to lens distance to the (Thoeretical) film/sensor to lens distance. (Most long lenses are physically shorter than their theoretical focal length. That's the true origin of the word 'telephoto', the lens is optically 'telescoped' into a shorter package.)

In reality this varies a little as the lens moves in and out to focus it, but in practice you just use the focal length of the lens. So for out Heron which is about 10,000mm away with a 400mm lens the magnification is 400/10,000 = 4/100 =.04. A heron is about .5m tall (18inches roughly), and 500mm x 0.05 = 20mm. The hieght of a digital sensor is about 16mm, so that's full height, but a heron is a tall bird, so portrait mode might be better, and that will be closer to 24mm.

So in our example, a 400mm lens will do but only for an animal half a meter in size, if you can get thirty feet away. And that's pushing your luck. (The nearest I ever got to a heron without sitting all day in a hide hoping for it to show was twice that distance!)

Most subjects will be smaller, or further away. Getting within 150ft of a deer in clear view is quite a challenge even for an expert stalker. At 1.5m tall with a 400mm lens, the image will be 12mm high. If the subject is a grizzly bear, then I doubt you would want to be that close.

Of course if you are wanting to photograph smaller animals, then the problem is compounded. Especially if they are easily spooked.

In essence you want as long a lens as you can manage, so you can photograph from a comfortable (for the amimal) and safe (grizzly bear) distance. However, as in many instances you won't be able to control that, and the range of animals you want to photograph will vary in size, you really want either more than one lens, or a really good zoom.

Really good zooms of long focal length are very expensive, so two lenses might be a better option, or a long lens with a factory matched multiplier would be almost as good. (Zoom lenses cannot perform at optimum over all the focal lengths available, so really good ones are difficult to design and make.)

So you first need to decide what focal lengths you need.

Then you have to consider camera shake. As a rule of thumb you need an absolute minumum shutter speed of 1/(focal length in mm) for hand-held shots. As you will be using long lenses, with small apertures, you won't be able to take shots hand held.

One (partial) solution is to use an image stabilized or shake reduced system.

Image stabilization is built into the lens, and works by moving optical elements to compensate for vibrations. This makes the lenses much more expensive, and will eat batteries. This has the advantage that it is always optimal for the lens.

Shake reduction moves the sensor in the camera, to achieve the same effect. It makes the camera a little more expensive, but the lenses are a lot cheaper, and that's where most of your money will go!

(Note, that digital image shake compensation is not the same thing, and reduces the image sharpness.)

Of course the traditional solution is a really sturdy tripod. Most tripods are simply not up to the job, so you need to check out as many reviews as you can. But be aware a really good tripod will not be cheap.

The camera mount must be really rigid if the camera is not to move during exposure (A camera with a mirror-up function can help. The mirror is the Major source of vibration in a camera, this allows the mirror to flip well before the shutter fires allowing time for vibration to die away.) and the tripod itself must not flex or twist.

A tripod with the means of suspending a weight underneath is useful, extra weight will make sure the tripod feet are firmly placed and help pre-stress the tripod so any residual 'slack' is taken up. (A simple hook that you can hang a kit-bag on will suffice!)

A good tripod and head could cost £200 or more alone!

As for selecting the lenses....

Canon do some very long focal length lenses but they are also very expensive (£2000+) These include a zoom with image stabilization, and a dedicated multiplier to double the range. A good used example will cost over £1000.

However, you should be aware that Canon are generally quite expensive, and other manufacturers produce similar systems, at various prices. I would look at Nikon, and Pentax, these brands are still well regarded.

500mm lens will not function with my Canon digital Rebel XT.

This lens will work with Canon cameras. I use one on my Canon 30D. It is a fixed F8 you can not use auto or green box because there are not any contacts on the lens to talk to the camera. Its back to the basics manual adjust shutter and ISO to the get a correct exposer. DEFINITLY NOT A POINT AND SHOOT LENS.

Conveting SLR lenses to Canon Digital

Canon makes several digital bodies which are "compatible" with those lenses. There are some obvious problems: 1. autofocus may be an issue; 2. the light meter may have to be programmed manually; 3. some of the digital features from the body side will not work if the lens cannot do what is asked of the computer. That all aside please consider the conversion factor as well. Digital sensors are not all the same format as 35mm sensors. So some bodies will be out and other you may have to compensate (ex. 1:1.3; 1:1.6). What this really means is that for instance on a 40d body, the 500mm lens will really be 800mm (500 x 1.6 = 800). Go to the website and look at the specification for the lens mount. If there is none there (as in the 1ds MKIII and 5d) there is no conversion factor as the sensor is full frame. Otherwise the 1.6 is the convertion factor. I would also stay away from the rebels as they are really built for the newer line of digital only lenses from Canon and will not be truly compatible with your lenses. Not that they won't take great pictures they just are designed differently. My recommendation is the 5d for many reasons: construction, full frame sensor and balance between features and price. Good luck.
