OMD+7-14mm outresolves A900+12-24mm

I've never been too happy with the Sigma 12-24mm (version 1) since I bought my A900 and sold the Tamron 11-18mm I had been using previously on my a580, partially due to no longer having live view on the A900 (I love live view for UWAs) and partially because it didn't seem to be a particularly sharp lens.

Well I just flew out to Baltimore for a week trip and at the last second decided I would take my OMD kit instead of the fullframe kit, bit the bullet and bought the 7-14mm to go along with my 20/1.7 and 45/1.8, which turned out to be a perfect travel kit (I'll probably add one of the tele zooms soon as well, was the only thing I missed).

I had a chance to test the 7-14mm vs the 12-24mm and found some very interesting results. The 7-14mm noticeably out resolves the 12-24mm, even with the lower resolution 16mp sensor of the OMD, vs the 24mp sensor of the A900. Even when I upscale the OMD/7-14mm output to the same framing the 7-14mm is noticeably sharper.

Looks like the OMD/7-14mm combo is my new go to UWA solution, and I can get rid of the Sigma 12-24mm. Another added benifit, the OMD + 7-14mm weighs about as much as the Sigma 12-24mm lens alone!

7-14mm shots at 5.6, 12-24mm at 5.6 and F11 for equivalent DOF, the 12-24mm sharpens up a bit by F11 but is still outperformed by the 7-14mm.
