35mm find that prime.

I should mention, I had changing light conditions, partly overcast to sunny, changing colour, don't try to judge by colour cast.

First from the picture reduced to 1080

I say #2? I almost voted for #6 but something about the color rendition tells me that's the Tammy 17-50?

All images taken at ƒ 5.6, sadly the Tamron 17-50 is front focussed +10, it's now set to zero and works perfectly, but, I'm not reshooting the test. Maybe later with the 21 ltd.
Also, each image was shot with different AF settings, I set the AF to closest focus or infinity and made the camera focus the lens from scratch. Every lens had at least 2 missed focuses and one clear winner. Only the 18-55 gave me two roughly equal best images. Once readjusted the Tamron 17-50 gave me 3 out of 5 sharp images. On some lenses differences in AF were noticeable even on the distance scale on the barrel of the lens. (With totally explains why I've learned to take at least 5 images of every static image.) The focus point selected was the blue squiggly lines on the shield.

Tess, just told me to quiet down, she is afraid I might be bothering the neighbours.

Having 7 to choose from really cuts down on the odds of guessing right.

See I just knew it...

You just listen to the "Lovely Tess", she knows what she's about. But worryingly I thought all your neighbours were miles away.

A grumpy park Warden named Leona, and her ex -Ontario Provincial Police husband live down the hill from us, but they both claim to be "anti-social" and we don't see them much. The dogs do bark when they get home and close their car doors. Leona has one of the funniest, driest sense of humours you'll ever meet. We share a common right of way. so most of time when I see her we are out diverting the flood waters threatening to wash out our road. Then there's some bozos who own a 20x20 foot cabin on a 30x30 foot parcel of land between us and the road. It's a small cabin, but they make a heck of a lot of noise when they're up from the south. We generally try and be camping when they are here.
SO we do have our issues from time to time. Not to mention that a winter skidoo/ summer ATV trails goes just down the hill, so we get noisy smelly machines going by from time to time. But I can still safely walk naked in the yard. (I know you want to turn your imagination off right now, but, I also know that won't work. Gotcha.)

Wow, 432 views, 26 guesses.... 5 distinct contributors to the thread, I have to assume people are finding this pretty tough.

What I get from your tests is that I do not need all the lenses I have because they will give me the same results most of the time

I think people will be really surprised when I release the results. But that's probably a week away. It's too bad, I don't have any of the 3 amigos or other top notch Pentax lenses.
