    Comparing ALPHA to 20D/30D/Xti

    Has anyone been able to overcome the Sony's disavantage in higher ISO noises with diffrent lenses? The Alpha seems like a great camrea, but the Canon's lineup is just such a powerhouse of previously great inovations that its hard to get a good comparison.

    Personally...I couldn't use a 400D because of its size, but it is the closest in pricerange and features.

    Thoughts?

    Re-read your post and you're done with your research. You want to be in the Canon family, the XTi is physically too small for many people, unless you are buying used the 20D doesn't make sense as the 30D with rebates is cheaper.

    You can research till the cows come home and you are going to end up with the conclusion that with today's pricing and rebates, the best choice for someone without pre-existing lenses is easily the 30D.

    Been there, done that, my 30D came Fed-X this past Friday.

    Red face High-ISO noise

    IMHO, I think you guys are wasting your time worrying about high-ISO noise. If you are shooting properly and with decent equipment, your ISO should not be over 400 for 90% of your shots. I would concentrate IQ there... but not higher, unless it is just horrible.

    So sayeth me... LOL

    Get a SONY and just stick it to image sh-sh-shake.

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.

    That is a Cokin 13-image filter. It does in the real world with one shutter trip what folks struggle to acheive in Photoshop to acheive.

    I like using the multi-image filters when I already have the shot and just want to "spice it up" a little, with some S.E. They come in several flavors... 5, 13, & 25. I also have the "mirage" filter, which I rarely use.

    These filters were developed before digital and photo-chop became popular, but they still work with optics... and quite well, too.

    I agree.

    Pheller, also good to bare in mind that lenses are expensive. You will definately save with Sony's A100 built-in IS (Image Stabilisation) system, by a few hundred $$$ on every lense that you purchase.

    In all fairness, even Sony's line of lenses do not come cheap. As with Canon's.
    Therefore and to re-iterate, better equipment = no high ISO noise issues.

    Lightbulb Third-party glass for the SONY A100

    You do not necessarily need to use SONY lenses to get superior looking shots. TAmROn, Sigma and Tokina have made lenses for the Minolta-mount for years on end... and they work just fine on the SONY A100.

    That certainly is some good glass. You will really unnecessarily overspend, using the OEM glass first. I, personally, would only spend my money on glass that I simply could not get any other way.

    Sony A100

    Just bought the A100, looked at the xti, I like it as well but the deciding factor was the camera IS not lens based. As far as the high iso issue I think that is overstated.. (as stated how often do you shoot above 400 or 800) I have not seen any dslr in above 800 iso range that I would say is great.. So far this is a great camera..
