Phottix Bellows Macro Canon

Interesting little device that separates your lens from the sensor to change focal distances and magnification. Useful in lower settings, but it would seem to be nearly impossible to utilize when fully extended. Any lens aberrations worsen as the lens is moved away from the sensor. The aperture must be set manually before removing the lens from the body and installing the bellows as there is no electrical connection from the body to the lens through the bellows. The mechanism contains a large amount of backlash in the geared drive and there is no shaft to synchronize between the left and right supports, so the lens may not be exactly normal to the sensor if not tightened well before taking an image. The amount of light in the sensor focal plane is reduced as the lens is pulled away from the sensor. This makes your lens a lot slower and can make it difficult to manually focus the image. All in all, a cheap way to have an introduction into macro photography with the lenses you already own, but beware that their imperfections will be much more apparent when moving them out of their original focal plane.EDIT: Drop one star for being the same product as others at a higher cost, such as  Fotodiox macro bellows for Canon EOS Cameras, Fits Canon EOS 1d, 1ds, Mark II, III, IV 5D, 5D Mark II, 7D, 10D, 20D, 30D, 40D, 50D, 60D, Rebel xt, xti, xs, xsi, t1i, t2i, 300D, 350D, 400D, 450D, 500D, 550D, 1000D

De una calidad muy mala. Componentes plásticos muy endebles, pero sobre todo, conectores malísimos que dañan los lentes originales canon. Estoy arrepentido de comprar este artículo.
