    I've done a comparison between the Olympus m.Zuiko 14-150mm zoom and the Panasonic 20mm and 45mm primes on a Panasonic GH2.

    This is not a scientific lens review and not meant to be, but a test for me to see if there were significant differences in sharpness between the zoom and the primes, when used in situations I would typically encounter.

    There are some full-size samples if you click through to flickr and select "View all sizes"

    If there are differences there, they aren't the kind I'd ever notice. I can't really see 'em at full size, let alone normal viewing sizes. Part of what makes the 14-150 such a wonderful travel lens, combined with its small size and weight and useful range.

    As your tests show, in bright sunlight the superzoomlens produces pictures full of colour, contrast and sharpness - just like the two primes.
    ...just like the kit 14-45 zoom too I'll bet.

    I'd like to see a three-picture composite overlaying the three lenses on the body instead of the first picture on your blog, that'd be useful.

    I'd also like to see some low-light handheld shots at middling ISO where each lens is using it's MAX aperture, and what that does to shutterspeed ... and the results. Stabilisation may or may not bring the superzoomlens up to the prime's qualities in that situation : would be interesting.

    As I said, a test for my own uses. Testing is not something I enjoy particularly and I had to force myself to do this one!!

    Hmm... May, yes, if the scene remains static. Stab compensates your shakies (so does giving up beer), not the wind in the grass, not the motion of the ocean: speed calls for speed.

    There's no stabilisation with the lens on a GH2 anyway.

    Yup, looks like a good all round lens if you don't need extremely shallow depth of field and/or low light performance. As Ulfric said, the same can be said of the Panny 14-45 (though, over a narrower range.) If that fits most of your shots, then it's a great choice. The :43: system has produced some very sharp, though not necessarily fast, zoom lenses. However, it is important to note that it does not cover much of the advantages of those primes (e.g., several stops faster, macro capability on PL45.)

    Agreed, but a lens like this can be a fine central part of a travel kit. Just taking a 14-150 and 9-18 to cover a huge focal range in decent light, and something like the 20 f1.7 for those low light situations allows you to cover a LOT of ground with a minimal amount of lens swapping. I'd even bring a second body to have the 14-150 and 9-18 ready to go at all times and just swap out the 20 in the evening or when I go indoors somewhere.

    I so rarely use the 14-150 around my home territory that it sometimes seems like its not worth having. But on the road, there's nothing like it.

    Indeed, and thats all I was testing it for. For low light, macro etc. I would use the specialist primes.

    Agreed. I'm about to go off on several stock shooting trips, mostly landscape in (hopefully) good light. I wanted to test two things. Firstly did I do the right thing in selling my 4/3 PanLeica 14-150mm? and the answer to that was yes. Since the Olympus is only marginally less sharp and much more convenient. Secondly would I have to be using the primes all the time to insure optimum results? and the answer to that was no.

    I did feel both of these things from using it beforehand but I'd never actually confirmed it which is what I was doing here.

    As Ray says I will be using that on one camera and a 7-14mm on another & that will cover the majority of my outdoor needs. In a pretty light package. Since I'm making my living without a DSLR these days, its important to me to be sure that I'm not going to be disappointed with what I produce, and the 14-150mm Olympus is a very decent lens and strikes me as easily on a par with equivalent DSLR lenses.

    When I want to travel extremely light (i.e. one lens) then the M. Zuiko 14-150ED is the one that gets bolted on to me E-PL2 :smile:

    I do however, own the Leica/Panasonic 45mm ƒ2.8

    I wouldn't have expected that. The PL45 does seem a bit sharper at 5.6, but by 8.0, there's no difference at all.

    I have a new respect for my little "travel lens" and will have to keep this in mind for the future. I still find the lens soft at the long end, though. I know that wasn't your test, but I am curious if you had any feel for this lens at the long end vs. the PL 14-140? Just out of curiosity mainly.

    Very well done!
    I love using the 14-150 on my e-pl1 with th e vf-2; makes a superb carry kit.

    Ok home now and able to view on much bigger screen than my Dell Tablet! The Original size on flickr are informative; at F8 I see no real differences.
    What impressed me with Olympus and m4/3 in general, is that I have yet to see a bad lens!
    Even the 14-42mm mk I kit lens is really quite good.
    My e410/510 and now the m4/3 has turned around my opinions on zooms.
    At least those by Olympus ;)

    Thanks for these useful shots. I've just ordered a used 14-150 for my GH2 as a "carry-all" when I don't want to keep swapping lenses. I settled on the Olympus non-stabilised lens instead of its stabilised brother Panasonic so as to save myself a couple of hundred pounds! I figured that with the better high-ISO performance of the GH2 I could simply up the ISO rating and pretend I was back in the olden days without stabilisation.
