Warp my world

5 exp handheld HDR

In case you haven't notice... the above image is way wilder than usual. What happened? Make a lucky guess =D

Hmm... isn't that hard to guess eh? I gave in and bought myself yet another lens - the Tokina 10-17 FE. It's a fisheye zoom... first of its kind for DX sized sensors, and can be used on FX from 15mm onwards. (talk about future proofing)

INTRO TO FISHEYE

This lens is a SPECIALITY lens. Which means it is only useful in a few situations. Used too often, viewers will develop vertigo, and it might just turn them off. But when used the right way, it is able to get you ASS-KICKING perspectives no other lenses can.

Fisheyes have geometric instead of volumetric distortions. That is to say, objects retain the same area in the picture no matter where it is placed. Rectilinear lenses, say the 12-24, have volumetric distortions, stretching objects placed at the edges, making faces and bodies look wider than they are supposed to be. However, fisheyes curve any lines that doesn't pass through the center, so there are subjects that you shouldn't shoot with a fisheye under normal circumstances (ie buildings/landscapes).

COMPOSING WITH FISHEYES

What i love about this particular lens is the wide-ness. It's sick. You get the full 180 degrees FOV, meaning that EVERYTHING in front of you will be in the picture. That includes part of your feet or maybe your shoulder, but more commonly, your shadow. The widest rectilinear lens at the moment is the sigma 12-24, but that is only about 120 deg FOV. Imagine how much wider this is! The extreme wideness and unique distortion means I have to learn to compose in a very different way.

To get use to this new persective, I stuck the camera to my eye as i walked around the park. With the distortion, I have the ability to "bend" objects, warping them to aid my composition. This also means that how I frame my picture will be more important than before. You can't simply crop the image in post.

HANDLING & BUILT

The 10-17 is a very compact and light lens. Despite its solid metallic body, it only weighs 350g. (the 12-24 weights 750g). It is only slightly larger than a 50mm prime, making it an ideal walkabout UWA, provided you can accept the loss of corner detail when pictures are de-fished.

PERFORMANCE

Wide open, this lens is not very sharp. Purple fringing is evident, even after the Expeed processing. But stopped down to f8 and sharpness is much more acceptable, although still not as sharp as any other lens I own.

Edit: I made a serious mistake on leaving AF Fine Tune ON. (Apparently D300 doesn't allow fine tuning of different 3rd party lenses) With it off, I get much better results. This lens is surprisingly sharp all the way to the edges from f5.6 and above!

It is surprisingly resilient to flare though, and the 6 aperture blades give me very nice sunbursts. This is important as the lens is so wide you almost always get the sun in your picture.

Matrix metering will go wild outdoors, due to the super high contrast of the scene. Use center weighted, manual, or if possible, HDR like what i've did. (it helps if you can rattle off at 8fps hehe)

IN CONCLUSION this is a very unique yet versatile lens. Lightweight and compact, I believe it will be with me for the non-important social gatherings, or walkabouts more often than the 12-24.
