Originally posted by Marktax The only comparison shots I've had a moment for were at a scientific reception last night in a dimly lit museum lobby. Identical K-S2 camera settings, 20-40mm Ltd and the K-S2 Kit lens, both at 34mm zoom. Tungsten WB. These are straight OOC jpegs, "Bright" Custom Image setting with factory defaults, except that I had set sharpness to fine sharp. The full frame images were downsized for posting. A couple of 100% crops follow. No PP changes to the files other than raising exposure for the center crops. 2sec timer with camera sitting on a balustrade, steadied by hand (which I hope introduced no movement). 18-50 kit lens first, 20-40 second; the 18-50 is slightly darker in spite of the same settings. I would much rather have had a better-lit scene but weather and work have not been conducive to photography.[
That is pretty disappointing results. I guess it's not so disappointing when you consider that it's just a relatively inexpensive kit lens compared to a much more expensive lens, but it takes away my interest in it. It does make the 20-40 lens look more attractive, especially in silver. I know myself enough that I wouldn't be satisfied with the kit lens, I'd leave it at home. If I really want a small zoom, I can always get the limited.
Thanks for posting these, I found them very helpful! And the sensor looks like a nice one (but I expected that, I like the K-S1's sensor). Now I just need to win the lottery or something.
