    Wow, this lens is very sharp...



    CA are bad in certain areas. I took a pix in the living room with sun coming through the windows. Sun refected off of some items on the table and the edges had bad purple fringing.

    If pix is not troublesome lighting, then CA's seem to be fine.

    This sample is much sharper in person, before reduction and photo hosting.

    has weird swirly bokeh balls too, and not in a good way. Hard to go past that sharpness tho, especially considering the price and size.

    And the colours!

    I too see purple fringing around bright features when shooting this lens wide open or at f/2. Stopping down alleviates it and when you're shooting raw and use Lightroom 4.1 you can correct for it. Most fast lenses do this, I saw an example of the Panny 25/1.4 recently and the Panny 45-200mm even has purple fringing at f/8.

    If you were shooting on a Panasonic Body, or shooting raw, CA wouldn't be an issue. The 20mm is very clearly a lens that was designed to be corrected in post. It has pretty dreadful distortion for a prime too. No matter because it's so bloody sharp in the centre.

    Is that the issue? It is made for the Pan and the Oly does not correct for the CA?

    From what I understand the Panny bodies correct for the CA and the oly ones don't.

    My understanding is that Panasonic bodies will correct some types of CA, but not purple fringing(?).

    I never noticed much CA or PF with the 20/1.7 on my Olympus bodies. On my PL25, on the other hand, I see a lot of PF... anytime when I am wide open (larger than f2.8) and there are high contrast areas, like sunlight filtering through the leaves of a tree (even at times approaching dusk), it is pretty much guaranteed.
     
  8. I've had some really horrible examples of purple fringing on the 20mm mostly in areas of extreme contrast around the edges of the frame. However as Ad says, Lightroom 4.1 is just brilliant at removing it. When I get home I might try to dig up some uncorrected examples.

    I take it you saw more on the 20 than on the PL25?

    The more I think about it, I don't think I was trying to push the DoF as hard when I used the 20... mostly kept it around F4.
     
  10. Definitely. If you look very hard you can find a tiny bit on the PL25 (and O45 for that matter) but that is very minor. On the other hand, I think that the P20 is better controlled in the centre of the frame than the PL25 when shot wide-open. My PL25 seems to get a "glow" at f/1.4 but is mostly gone at f/1.6.

    both Pana lenses ive got, have terrible CA (P20mm and P14mm, used on my olympus bodies), which you got to fix in PP. no problem, i dont like the edges, specially on the P14mm, P20mm is better for that matter, I just wish Olympus would have better pancakes for the 17mm/20mm fov. im just waiting for photokina and see if they come up with that 25mm pancake. fingers crossed. i wish they have a better version of the 17mm or a better version of the P20mm, i just love the 35/40mm EFOV.

    When is photokina? I set my 12-50 zoom to 25, 20, 17 and 14 to see where I liked it for a street lens and I almost liked the 14 best! I thought I'd be more comfy at 17/20 as I loved the 35 on my film camera. I'd love some new primes, but I don't want to wait. I'd rather be able to shoot now. But if it'll only be a few months I can hold off and buy used for now so I don't lose a lot of money if I upgrade.

    What is this a picture of? I dont understand why the top two-thirds look like wood, but the bottom third looks like a cutout from another photo with blur? Am I missing something?

    Separately, I agree this is a sharpppppp lens. :)

    Sounds like you might be a good candidate for the Panasonic 14mm prime then! Nice and cheap so if you don't love it, you won't be spending big bucks either.

    Well, got just to try out each lens to see how it works for us. I thought I'd like the 20 for undercover work, but found the 12mm best for walking around and shooting at the hip without looking. Very fast focus and I need the extra area the 12mm takes in if I am not framing.
