I haven't paddled a sea lion but I see them pop up every so often for sale. Way back when I had a perception catalina and then a perception avatar - the latter was a great playboat in the surf & I probably shouldn't have sold it on
Now I tend towards low volume british built boats (I'm a fairly destructive force on a kayak).
I need to kayak in Australia, apparently.
The 18-135's doing a bit better. I think turning off highlight correction made a huge difference on noise.
I did this the other night while out on the water with the 18-135:
That's not bad with how much movement there was with the kayak & how dark it was.
Unfortunately, with trying not to use picasa, it's taking me forever to process images. Pentax photo browser hates me for some reason, when I try to modify a photo with it, it just turns the photo all black and won't show me the changes I made. so now I'm going through comparing what adobe lightroom shows vs. what picasa shows... For the most part, things look pretty similar, although in one shot I took of the moon, picasa brightened up & took out all details of the moon from the shot, while in adobe, i can see all the shadows, etc. on the moons surface. So I'm still experimenting with lightroom and learning all the controls.
I think the focus/sharpness is still soft when zoomed all the way out on landscapes, but I'm going to take the camera out in an hour or two and try to do some more diligent tests comparing it to the 16-45. I guess it's just mean comparing it to the 21 mm limited.
