♟️ Canon Ef 25 Extension Tube

Macro Lenses. Macro lenses are designed to let the photographer focus on a subject at a distance that allows it to be reproduced, in the image circle, at the same or slightly smaller size. If the lens can reproduce the image at life size, it is said to be a 1:1 macro lens. If it reproduces it at half-size, it is a 1:2 macro lens. What I did do is use two extension tubes with the RF 100mm and got over 2x magnificaiton (~2.3x if I recall correctly). I don't have a feel about how far away you can be with extension tubes and be at 1:1. And, if using an extension tube with an EF lens, is it best to do body to adapter to EF extension tube to lens? Extension tube sizes. Extension tubes come in different sizes, for examples Canon offers two sizes, 12mm and 25 mm in length. Other manufacturers offer different lengths, Kenko offers a set of three sizes 12 mm, 20 mm, and 36 mm. Fotodiox offers a set of three sizes 7 mm, 14 mm, and 28 mm. As the length of the tube increases the magnification Magnification with a 25mm extension tube mounted behind a 70-200mm f/2.8L IS II will range from 0.36x at 70mm to 0.14x at 200mm (extension tubes change the maximum magnification based on the ratio of the tube length to the focal length, so the longer the lens, the less effective the extension tube). Shot at f4 - 1/250 sec, ISO 200 from about 5 feet away, then cropped. The critter was a bout 1.5" long. I don't have the 70-200. I attached a photo of my rosemary bottle in the kitchen, taken with a Rebel, 50mm f1.8, and all 3 extension tubes from the Kenko set. I cropped slightly to lower the file size. Key Features. Well-suited for extreme close-up shooting, this Macro Bellows from Fotodiox is designed for Canon EF-mount cameras and lenses. This bellows has an adjustable 1.6-5.9" extension range, and is used to increase a lens's maximum magnification up to 8:1 for macro applications. A rack and pinion gear is used for smoothly adjusting the The Canon EF12 II Extension Tube is a simple accessory that moves the lens optics further away, thus increasing the magnification of the lens. It has electrical connectors so that communication between lens and camera is maintained, but no optical elements of its own. The Canon EF25 II Extension Tube does the same, but is longer and therefore Extension tubes transform any lens into a macro lens. Canon EF 135mm f/2L lens with stacked Canon EF 12mm and Canon EF 25mm extension tubes. Together, these tubes are 37mm which gives me a 37/ I use the Canon 12mm and 25mm extension tubes on my 100mm f/2.8 Macro and they do get a little closer and a little better then 1:1, but the only real way to get really close is to buy a Canon Macro Photo MP-E 65mm f/2.8 1-5x Manual Focus Lens for EOS.

This is accomplished by moving the lens 25mm farther away from the camera body's sensor/film plane by fitting between the camera body and the lens. The end result of focusing closer is a larger magnification.
