Alrighty, sorry about the harsh light, that's what I get for shooting at two in the afternoon. All these shots were either the Tokina 11-16mm or the Nikon 18-55:
The first six shots were all processed with the same white balance so you can see the difference between the Nikon and the Tokina (the Tokina is often referred to as a "cooler" lens)
Just for fun, I'll narrate in the second person, and pretend you somehow keep misplacing one of your lenses:
Let's begin with the Tokina on the camera, you frame something that looks cool, and gets some good perspective going on:
And you zoom in to 16mm, seems like some of the perspective's gone - also, seems half a stop brighter, not sure why...
So then you realize that you don't have a Tokina, and you put the 18mm on, but you can't quite find the same perspective. By now you're thinking "yeah, but that's totally not fair cause I framed all the cool stuff in the first one near the edges"
So to be fair, we move again and shoot some benches with the buildings in the background:
And then we zoom in to 16mm, because you're curious about this overexposing thing, and sure enough, it gets brighter again! (So naturally you drop the exposure by 1/2 stop in post, and then it looks like the rest of the series)
Well that was strange, that Tokina disappeared again, oh well, back to 18mm:
But that's not the same set of subjects, so you zoom with your feet til you fit the church on the left and the benches on the right. You go from 3ft away from the first bench to 30ft away from the first bench just to make it all fit, technically you should have gone further, but there was a street behind you and getting hit by cars wasn't high on your list of priorities:
And then you find the Tokina again, quite improbably in your back pocket. Clearly you wear cargo jeans... Fashion aside, you think "well now that I'm back here, how would this wide lens look?"
That's just dandy, you get some of the sidewalk in, and it pushes the perspective a little, but because the composition is totally whack and you've cut off the building, you flip it to portrait!
Alright, so you got a cool shot, with the sidewalk pushing the foreground, and the building stretching up to the sky. But you totally could have done that with the 18mm lens right? Wrong... and this time you definitely can't zoom with your feet, since the camera is angled up, and only 6" off the ground in the first place, there's totally a lot of earth in the way:
So by now, you're sick of shooting with a tripod in the middle of the day just to keep the center points of your shots the same as you repeatedly switch lenses. Not to mention, you're sick of switching lenses. You stick your tripod in the bag and run around with the Tokina for a little while shooting ultra-wide just for fun, and here's what you capture:
