Yeah it is rabies

Heres some aperture comparrissons to shop the sharpness of the lens at F/4.5, F/8, and F/32 at 17mm (the minumum, maximum, and optimum apertures). The crops are at 100%



As you can see it is pretty much sharp throughout, with the lens perfoming exceptionally wide open. A drop in contrast and a softer image, though with boosted colours is produced by the small aperture, F/32.

And heres a 25% size of the full image taken, lit by the light in my room (no flash). Same picture as previous F/8 crop.



Oh, and heres a tree from the beach
