Re: My ratings of six lenses' IQ after doing research...

This research is obviously unscientific. It is meant only to help me choose a mostly landscape lens out of the following six alternatives. These ratings are for image quality only. The ratings were formulated after looking at 25-30 landscape shots on flickr for each lens, usually at 100% view. The ratings are out of 5 points, and a 2.5 would be an average rating, meaning it was just satisfactory.

Sony 24-70 2.8 GM ..... (4.5/5.0)

Sigma 24-70 2.8 Art .... (4.0/5.0)

Sony 24-105 4 G........... (3.5/5.0)

Sony 24-240 3.5/6.3 .... (3.0/5.0)

Tamron 24-70 2.8 ......... (2.5/5.0)

Tamron 28-200 2.8/5.6 ..(2.0/5.0)

If someone has compared more than one of these lenses please let me know what your findings have been relative to these ratings. I would also love to hear why you disagree with these ratings. In fact, if you want to re-order, please do (based on IQ). I might revisit my conclusions. I hope I haven't insulted anyone who owns these last couple of lenses.


Lenses have character and you should purchase one that appeals to you.

I experiences this when I took a picture of a rainbow with my 24-105mm G.  I just did not like the result as the colors were just Muted or not well defined. So I put on my 20mm F1.8 Sony and even though I had to crop the difference was dramatic in that particular case.  Thing like CA, contrast, etc. make a difference.

So I think you have your ranking and should go with it.
