Regarding Magnification: The focal length is distance lens to sensor (film) when imaging an object at infinity (as far as the eye can see ∞). This measurement will be elongated if the object is closer than infinity. Suppose you photograph flagpole 10 feet tall from a distance of 20 feet using a camera with 50mm lens. How tall will the image of flagpole be ...

This Article ( http://www.dpreview.com/articles/6519974919/macro-photography-understanding-magnification ) may give you enough information or assist you to refine your question, specifically this sentence may be important: "If we shoot a 1cm fly and its projection on the sensor measures 1cm as well, the magnification is 1:1.". If you want an object that is ...

What lens would work for a canon 6D to take up close photos of birds far away in the trees? It comes down to three questions: How up close do you want to get? How far away are the trees? How big are the birds? In landscape orientation, your 400mm lens takes in 3.4 degrees over the height of the sensor and 5.2 degrees across the width. That means ...

The Canon 6D sports a full size image sensor measuring about 24mm height by 36mm length. We fit lenses to cameras based on the diagonal measure of the imaging area. In this case the diagonal measure is about 45mm. By tradition, we round this value up to 50mm. If a 50mm lens is mounted, and angle of view is delivered is label as “normal”. Mount a 100mm lens ...

I know what you mean about the big lens still not getting close enough. Tips though include: Set up an area if you can with a bird feeding station. Manage the type of food offered and the overall placement against a nice background. Although the 6D is your A camera, ideally your B camera could be placed on a tripod next to a feeder ready to be remote ...

You either need a longer lens (>400mm) or a telephoto extender. Telephoto extenders are a less expensive way to get additional "zoom" from your lens, but the image quality will not be as good.

In traditional miniature format photography (35mm... which equals an image dimension of 24 x 36mm) a 35mm lens was regarded as a moderate wide-angle lens. A 50mm lens was regarded as a 'standard' lens. The standard lens had an angle of view of around 46 degrees which approximated to that of normal human vision. That meant that when a photographer used a ...

The technical points basically boil down to three points Angular Resolution Distortion Perspective Since you need to get closer to the object using the 35mm lens, you are at least theoretically able to see more details. However, this is (a) only a small difference and (b) may be limited by by other factors like the sensor of the camera. 35mm lenses ...

The proof is in the pudding – the focal lengths are not exactly the same as yours, but the differences are obvious...

Thanks to my schwifty skills in Inkscape, the rotation here is slightly off but the following shows exactly what you're comparing. These are the fields of view of a Nikon 35mm (inner) and a Nikon 50mm (outer). So even when you're getting approximately the same stuff in the frame, the 35mm is much wider, focal distances are slightly different too. If ...

Do you have a selection of lenses (or a zoom lens) now? Shoot a table-top test with different focal lengths, repositining the camera to get tye same view of the foreground object. Then look carefully at the photos to see for yourself. If you're one of those peopke where this doesn't just scream at you, it's good to develop your eye to seeing the ...

If you shoot from the same position with both lenses, then taking the 35mm lens and cropping it to the same angle of view of the 50mm lens will give you pretty much the same picture, other than the differences in optical quality between the two lenses and the resolution lost to cropping. But even if you were to shoot with the same lens, shooting from a ...
