    I recently picked up a GM1 with 12-32mm kit lens. Since i have the Panasonic 14mm f2.5 I decided to do a quick n dirty IQ test at 14mm. I'm very surprised that the lenses are about on par at 3.5 (14mm) and 3.7mm (12-32mm) and at f5.6 (for both). For my test I focused on the dragons eye.

    Here's the original with the 14mm at f3.5. For pixel peepers all the images can be seen here:

    Other than bokeh and low light performance the 12-32mm looks as good as the 14mm (to my eye). The 12-32mm at 14mm does appear a bit wider than the 14mm. Focus speed on both (with GM1) are on par also. Since I have a Panasonic 20mm f1.7, i thinki i may sell the 14mm.

    looks good enough to me. I returned the Oly 9-18mm since it didn´t convince me so I´ll probably end up with the 12-32 and defish my Rokinon 7.5 fisheye or stitching for anything wider for the time being. Thanks for the comparison

    Great to see this comparison. Just got into the MFT wagon and purchased one of this lens. Wasn't sure of lens IQ, but the compact size is what sold me.

    I'm not surprised by the results.
    I have both and I think the IQ quality is just the same (= quite good).

    I'm not going to sell my 14 mm because:
    - it's a prime lens, so more fun to use - this is very subjective ;)
    - it's faster (f/2.5 vs. f/3.7 can make a difference)
    - it has manual focus
    - it's a real pancake (the 12-32 is not, when in use)
    - it's very cheap (used) so I didn't pay much for it, and I wouldn't get much selling it

    The 12-32 is a fantastic little lens, so there's no question of selling it;)

    comparing at the edges and corners is where you are more likely to see more difference in sharpness between lenses.

    Thanks for your test -- it matches what I've seen others say here, which is that the 12-32mm is a good kit lens and that the 14mm is a nice lens, but besides size and speed is not a lot better optically than the kit lenses.

    I recently bought the 12-32mm and sold the 14mm. I liked the 14mm lens, but I don't actually want the 14mm focal length often -- usually I just keep the 20mm lens on there. In essence, the 14mm was being carried along just in case I needed something wider. For that purpose, I'd rather have the 12-32mm in my bag, since it has added flexibility.

    Now, if 14mm were a preferred length of mine (and I know it is for some people on here) and I were regularly using the lens, I might very well have kept the 14mm, since it is faster and is very low profile when in use.

    Maybe it's my viewing device (smartphone) but the 12-32mm looks better in the f5.6 sample. Which doesn't surprise me.

    Def sharper at 5.6. I am enjoying using this lens on the GM1.
