    Default Extension design zoom/focus lenses: Does it matter to you?

    Seeing the release of the Olympus E1 system, and its range of lenses, from what I've noticed, at least the 14-54mm and the 50mm macro lenses are designed with lens extension focus/zoom systems - so the quinessential question is - does the fact that a lens that extends/retracts bother/affect you in choosing whether to buy it or not?

    I'm asking this because of my personal concerns when shooting in sports/outdoor situations - what I believe is that extending lens designs are much more susceptible to dust infiltration.

    Pardon my ignorance but aren't most zoom lens of the extension/retractable kind? At least mine are.... maybe that's bec I am using the non-pro lines.......

    It does not matter if there is tiny dust in the lens, as long as there is no fog elements or fungus in it, it ok.My Minolta 24-85 got a strand of hair in it and it still gives me wonderful pictures! sometimes I wonder why people is so particular with these minor issues. the product is meant to be use, unless that person is a collector who don't take pictures and leave the lens in a clean room.

    Well I suppose we all spend a lot of money on our lenses and if some dirt or grit gets in to screw up the mechanical parts, it's going to be a real heartache... and not to mention costly clean-up or rebuild by pros...... but I hardly actually clean my lenses..... just use tissue to clean the filter only.......

    If it's the mechanical problem like cannot focus, cannot zoom then it all right to send the lens for servicing, repairing. but a tiny dot on the lens and they say it'll affect the pic quality!! "making a mountian out of a molehill". but then the money is theirs, they can spend it anyhow they want. sometimes small dots cannot be clean off, and they risk the chance that more will get in when the lens is open up.

    extension design design..yes

    the classic example ---i see it as a contradiction:

    canon EF 28-70/f2.8L . everything about this lens is good except for the fact that it extends out as u zoom towards the wide end. go to www.photozone.de--there the main guy klause also has the same opinion.

    for the sake of completeness, i personally wouldnt use that lens ever again coz it just simply feels so ironic.

    then again that issue of extension may not bother u at all...so its really up to u

    exactly. i thought that the 24-70 was ironic - one thing being a L lens yet it extends for the wide end...
