I'd really apreciate that too, I compared those two in shop and it didn't seem to me as such big difference, but would love to see propper wide angle comparison shot on some landscape or so....
do you have any? pleeeeeeeeeeaaaaaaaaaaaaase....
Regarding the wide angle shots, I'll do my best, Axl.

They will be done properly, i.e.:

1.) Camera on a tripod.
2.) Same aperture
3.) Taken moments apart

something out of focus in the scene? to compare bokeh?

Well, I'm off to do some lens tests.

I don't know how much I'll get done, but there should be photos of:

1.) Fighter planes
2.) Cameras
3.) Candy
4.) Musical instruments
5.) Monsters (don't be scared)

More later.

You did crop the 16mm shot, right? Do you mind posting a comparison between the wide angles on both lenses?
OK, this is for ricardobeat, and axl, and anyone else that's interested.

A comparison between the 18-55 and the 16-45. Both lenses at their widest angle of view.

Camera on a tripod in the same location, shots taken seconds apart at dusk, ISO 400 for all.

18-55 @ 18mm @ f4.0, 1/125 sec

16-45 @16mm @ f4.0, 1/125 sec


I also have f5.6 and f8.0, but to save space, I'll just post f8.0 unless someone really wants to see f5.6

Now, we'll go inside.

This is a room which is approximately 30 feet wide by 50 feet long. The camera is on a tripod about 10 feet inside the entrance.
18-55 @ 18mm @ f8.0 .5 sec

16-45 @ 16mm @ f8.0 .5sec

Here's an odd shot.
18-55 @ 18mm @ f8.0 .3 sec

16-45 @ 16mm @ f8.0 .3 sec


That's it for tonight; more tomorrow.

So, what do you guys & gals think of the two lenses?

Many thanx Mike,
finaly I can see it as I wanted it. Really big thank you...
And I have to say that I didn't think that there'll be such a difference, maybe I'll have to reconsider my next purchase

You're very welcome, axl.

I'm glad to have been able to help.

Plus, doing this test gave me something to do, and I learned a little about these two lenses.

Now, about the monsters I mentioned.

So, I'm minding my own business, doing some lens tests with my 6x7 as the subject...



When suddenly I hear this roaring.

IT'S THE EV MONSTERS!

They'll bother any photographer they can, because they stink at taking pictures themselves!


HEY! STOP STOPPING-DOWN MY LENS!


WHAT DO YOU KNOW ABOUT MIRROR LOCKUP? GET OUT OF THERE!


Long story short, it cost me $20 to get rid of them!


But I did get some good close-ups.

I'll post them later.

Mike
All the above photos taken with the 16-45.

Here are some close-ups.
16-45 @ 45mm @ f4.0 1/125 sec ISO 400 for all.

16-45 @ 45mm @ f8.0 1/20 sec

16-45 @ 45mm @ f16 1/6 sec


I also have f5.6 and f11, but I think everyone gets the idea.

I have to agree with all those who said that this is a sharp lens. I think this is pretty good for a zoom lens.

Mike

Enough green!

Now let's see how it handles warm colors.
16-45 @ 45mm @ f11 1/5 sec

16-45 @ 45mm @ f4.0 1/125 sec


Even though the top photo @ f11 is sharper, I think this lens has pretty good color reproduction wide open @ f4.0.

Forgive me for not rotating these two photos, but they seem to lose something when rotated.

One more wide shot of the hall from the entrance.
16-45 @ 16mm @ f11 .7 sec
