| p.1 #20 · Thinking of swapping my Panny 7-14 for an Oly 9-18. |
Haven't had a chance to formally test them thoroughly against each other yet, but here are my early conclusions:
Wide open, the 7-14 is clearly superior in sharpness when both are at 9mm. Center sharpness is similar, but the 7-14 is much better on the edges. At f/5.6-f/8, the differences equalize a fair bit. Close up, they are very close, while at further distances, the Panny takes a slightly larger lead in the corners. However, they're not that far apart from what I can see. The 9-18 has much more lateral CA, but it can be 100% corrected with Lightroom's CA tool in one click. The 7-14 has much more purple fringing, and this is harder to correct. The 7-14 at 9mm has less distortion than the 9-18, which shows visible barrel distortion.
This is a quick crop comparison of a flat subject up close (a poster at my desk). Crops from center, edge and corner, both lenses at 9mm and f/5.6. You can see they are very close to the edge, with the 7-14 being sharper in the corner, though the residual PF is visible a little (this is CA corrected on both).
I plan on taking some outdoor comparison shots this afternoon. I'm still very torn on which one to keep. The 7-14 is the better lens optically, at least with regards to sharpness and distortion...and it goes MUCH wider than the 9-18. However, it's also MUCH larger, and I won't bring it as much as the 9-18...and the 9-18 isn't too far off optically, and performs better against high contrast edges and flare, plus avoids the purple blobs issue on the OM-D.

Hey Jordan. I did a head-to-head on these two lenses a couple months ago, though it's probably not up to your rigorous standards. I'm writing for a more general audience.
I actually had read your comparison before doing this. I think you did an excellent job. My final comparison won't be a whole lot different from how you did it, though I'll probably include a few different distances.
