  • dwRK's Sigma 19mm f2.8 EX DN for m43 Short Impression

    I have both 19mm and 30mm for two weeks now. This "review" is for 19mm.

    First up...pictures or it didn't happen...

    All pictures are JPG straight out of camera. Only processing done is resize.

    It is amazingly sharp in the center...a little less in the corners...but still sharp sharp sharp...good enough for big prints.

    CA is present...very minor not annoying...easy enough to remove if required.

    Colour is neutral as far as I can tell.

    The most amazing is flare and ghost control...great contrasts to boot...see for yourself!!! Simply amazing...

    Night...handheld...

    ...handheld...here you can see what the designers are doing...

    Bokeh in a wide angle? Absolutely! Front and rear defocus nicely...neutral nice round evenly lit discs...indication of smooth bokeh...

    This lens takes about 1 second to start up...not a problem for me but still annoying.

    Focusing elements move and rattle without power. It is normal. Once powered up...its held in place/focus. Focusing is almost silent...you need to strain to hear it in a silent room. Focusing speed is quite fast...just a tad slower than MSC lenses.

    38mm FOV is fine by me, used to it on my CP4500. I use this as a "wide normal".

    This lens is just about perfect. Optically I'd say approaches Leica...a real bargain for the asking price!!!

    Edit: Added Bokeh, rattling, iso and f details, updated some text.


    Additional tests...

    Star bursts...

    P4150632 by dwRK, on Flickr, f2.8

    I've set up my cam for AF+MF and magnified view during MF...the focus ring while looking nice is a bit too big/tall IMHO as I frequently move it during normal handling and LCD jump to magnified view...annoying.

    Great short review! Heard a lot of good things about this lens from overseas but it's good to hear one from here. Is it available already in Malaysia and what's the price like?

        Thanks.

        Visiting the US at the moment...bought it for USD199. Not sure how much in Malaysia, I checked few weeks ago no one selling yet.

        Will try to take some star burst when weather permits...a weather front is moving through and has been cloudy these few days...not too high hopes for spectacular star burst as blades are well rounded with just a minor "point" between blades.

        All taken with E-PL1 optimized for JPEG printing...bought the kit at USD300. Body now selling at USD150...I might get another.

          just read this today...
          http://www.lensrentals.com/blog/2012...ion-comparison

          comparison with a legend...leica summilux 50mm f1.4...and a modern great...sony zeiss 24mm f1.8...

          also LL had compared the sony with summilux 24mm, and in some areas the sony is better...

          fyi...the sigma for m43 and nex is essentially the same lens/optics...just different mount and electronics...

          summary...

          ...at f2.8...centre loses out a bit to both...corners better than both (average mtf50 is higher)...
          ...at f4...centre and corner lose out a bit to both...

          like i have found...the 19mm has great optics and great value...

          but guess what...sigma 30mm sharper than both at f2.8 and f4...only loses out marginally to the summilux at the corner at f4!

          anyway i'm not delusional...if you need f1.4, sharpest across, at all apperture...the summilux is perhaps the best there is...too bad they don't have the hyperprime for comparison...

          also the sigma sharpness peaks early...f2.8 to f5.6...this may be a problem for some people...

          cheers.
