Need to replace my Sony W1

There are even faster lenses made at the 50mm focal length for 35mm cameras - and they are very expensive (or not very good). Zoom lenses rarely have large maximum apertures, likewise 'telephoto' lenses and wideangles. This one is $80 buck. It says it can see what my eyes can see. Sound pretty good. Will this work for letting more light to go in? Do you know the different from this lens to the one in my Sony? http://www.amazon.com/gp/product/B00...Fencoding=UTF8 That lens is certainly 'faster' than the lens in a Sony DCS-W1 - its maximum aperture is f/1.8 so it's about 2.5 times 'faster'. You won't be able to use it on your compact digital camera though; it is made for the Canon 35mm SLRs with an EF lens mount. Used on such a camera, it will be capable of performance far better than any digital compact can match - but it has a fixed focal length, it is not a 'zoom'. I suspect that "see what my eye can see" refers to the focal length; traditionally, a 50mm lens on the normal 35mm negative is considered to give a 'natural' or 'realisitic perspective effect' when you view a 10x8" print (or 12x8" with no 'cropping') at 'normal reading distance' - although in fact 50mm is 'a bit on the long side' if you apply the classical 'focal length = diagonal of negative' rule of thumb for deciding what is a 'standard' lens. You get the same angle of view (and 'perspective effect') at or near the 'wide' end of the zoom range on most digital compact cameras. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~ |
