Which is the prime lens?

Between the 18-55 kit lens, the 18-135 DC and the 21 ltd. three shots off the tripod at within a short period of time all at as close to 21mm as I could get them and cropped. See if you can tell. Exif data is intact.

No, it's definitely #1. The voices in my head insist.

And the voices in Rio's head command him to use a dremel. I'd listen to him.

Darn, I had to find a way to figure it out. I'm going to be more careful with the file names next time. But I'm 99% sure it's picture #3 axl gets the imaginary cupi doll. #2 is kit lens, altogether not bad for $129/ I saw someone clearing them yesterday for $70.

with that kind of exposure, it's difficult for me to judge. it is more like playing pinata honestly speaking.

Slower shutter speed on #3 due to the smaller front element of the 21mm?

I would have gone for #3 but it's hellishly close. Compression limits are a great leveler and don't help matters much either.

I am going with #3 by judging the top left corner (tree branch is much sharper then the others) of each shot.

#3 is the DA 21 LtD

But of course we can't stop there.

This time the choices are 90 Tamron Prime, DA*60-250, DA 18-135 and, Sigma 70-300. A $ 300 lens, 2 $450-550 lenses and a $1600. You can either guess what was taken by the prime or try for the grand slam and try and guess all four. It's abit harder, even though the tripod didn't move, they didn't all focus on the same place , and the last one, the sun went down and had different light than the first three.

4,

Looking at the exif data is cheating.

The sun wasn't out earlier in the day. the next ones are better. And, if you saw the origianals before compression the differences are more pronounced. Colour wise, the DA 21 ltd defintiely gives the warmest most inviting colours. The next 4 originals are even more distinct, you should all come over to my house and we'll discuss this over a beer.... ok, ust kidding. I'll post again after you've all had your say. These are all pretty close to 1:1 crops.
