Comparaison 10-24 vs18-55-vs17-70

Following some advice and a lot of reading here and in some book

I decide to buy the K-X kit and some other lens

I have the Pentax DAL 18-55 who come with the canmera that I call a general purpose lens

I bought second hand the Sigma DC 17-70mm f2.8-4.5, that I could use for some portrait and a good all arounsd lens

And finaly following advice on Scottt Kelby bought a Super wide angle Tamrom SP10-24mm f 3.5-4.5 for landscape photo and to capture wide area for interior photo

I want to make a very simple test of comparing the widest opening for these 3 lens from the same position in auto mode without change or editing any of these photo.
The photo are not well focus but that was not the point
This is giving a good understanding of the difference between the 3

I am very happy in my purchase

The photo are not well focus but that was not the point. Automatic no adjustment at all

1) Pentax 18-55

2) Sigma 17-70

3)Tamron 10-24

What is your point?

It looks like the kit is as good as the Sigma so sell the Sigma :-P

The wide is obviously... wider
