    For those of you that have used both:

    How does the Sigma 19mm f2.8 compare with the Lumix 20mm f1.7 in terms of image quality and sharpness?

    They're quite close, but the 20mm is 1.5 F-stops faster, and also smaller and lighter.

    The 19mm I tried had faster AF speed than my 20mm (so does my 30mm Sigma for that matter).

    How does either of those prime lenses compare to the kit 14-42 in terms of sharpness and image quality?

    It own the 20mm but neither of the sigma lenses. From what I have seen and heard across the Net; the sigma 19mm has image quality that is very close to the 20mm. I don't think there is much doubt that the sigmas lenses have better IQ than the 14-42mm kit lenses.

    Sigma 19mm Pros:
    - Cheaper
    - Fast Auto Focus

    Pana 20mm Pros:
    - Much smaller
    - Faster/Larger Aperture (meaning both shallower depth of field and better low light results are possible)

    In the UK the sigmas are priced at £180 ish compared to the original 20mm at £250 ish. In this comparison I find it hard to recommend the sigma unless super fast AF is something you really need. However the older versions of the sigma lenses (exactly the same lens, just looks different) can be found occasionally for £100 ish. This makes the value of the sigma far greater.

    Panasonic 20mm is:
    -slightly sharper and more contrast
    -no AFC, slower focusing
    -cooler colors
    -has bad CA that Panasonic cameras fix well in JPEG, but fixing it in RAW is more work and sometimes the results don't match in camera fixes

    Sigma 19mm is:
    -Nice warm colors
    -Does AFC and focus a bit faster
    -not as bright

    Both are great lenses, but IMO the Sigma is better except for the size factor.

    In my experience the image quality is better and sharper with both. And they will both do better in low light.

    In the U.S. we typically see used copies of the 20mm Panny selling for $250-300, while both Sigmas tend to sell for $100-130 second hand, so the Sigmas can be a very nice budget alternative at those prices.

    I had the 20 and it was very good. I've not had the 19 and never will because the 20 isn't that much more expensive. I do have the 30, however, and I think it's amazing!

    I like Sigma lenses, they give great value for dollars. The 20mm, however, is an even better value. It's small, sharp and has excellent IQ. For the small price difference I would take the 20mm every time. :cool:

    So would I, if it focused faster and didn't band at high ISOs on Olympus bodies like my E-PL5

    I guess if you are comparing retail prices. However on the used market the 20 goes for $250-300 while the 19 goes for $100-130.

    I picked up the Sigma a couple months back at Henry's (in Canada) when they were blowing out the ver.1 of the lens. It was $119 brand new and a bit of a no brainer. I've certainly had no complaints with it. Here is a shot from a walk with the dogs...

    Well, since the price difference is about $125, and image quality is pretty comparable between the two lenses, I think I'll consider the Sigma first to see how I like it on my OMD. thanks for the information.
