Default Sigma DC 3.5 to 5.6 / 18-125mm

This was the first lense I bought when I bought the K7 body only, but as I quickly acquired others this has remained in the bag for too long perhaps. So this afternoon I thought I'd run it through it's paces to see what it could do ........ I was surprised, despite having a very useful range it also offers 'macro' from 0.34 metres (about 13") and shots came out reasonably sharp with very little CA / Purple fringing in high contrast areas. Colours seem really good too. It is also light and compact. I really should use this more - it could be an excellent street lense !

I have applied absolutely zero PP, except for cropping, on these shots.

#1 - full size
#2 - 100% crop
#3 - full size
#4 - 100% crop
#5 - full size

I would really like to hear your opinions and if you have spotted any issues.

More below.

Like you said they look good enough and I guess it would make a great walk around lens. For that reason I got me a tamron 18-200 a while back and never have regretted it. I allways take it with me, even when it makes no sens.

Cheers

Ronny

Looks good!

Not sure if you were using manual or auto focus, but the point of focus seems a little soft in some of the images. Without checking the EXIF for each image, can't tell what focal length each one was in, so not sure if this is just a result of the extreme long/short side of the lens.

Thanks Ronny, I think you are right, I'll have to carry this around more.

Thanks Ash. - I'm sure it was me since I think all were in MF except for the tennis ball and the last 3 shots. My eyes are just not that great I'm afraid and I seem to front focus - I'm looking at focusing screens to help me with that particular problem.

That might be it then, but I was only being hyper critical, the full size shots look fine.
