Just based on what you have posted, it seems the 18-135 lens is back focusing somewhat. (PhotoMe isn't reading the AF info from the Exif, so I'm guessing you used auto focus)

Yes I used autofocus.

Looking at both pictures in PSE 10 I think both lens photos need sharpening, more in the 18-135 than the 70. Maybe I should set the camera to sharpen a little.

I agree with Brian (VTphotog) that you'll probably get better results if you calibrate the lenses.

If you still want to know how I resize - I use a free photo editor called Irfanview. Very simple (too simple for effective post-processing, but great for resizing). Be sure you download both the Irfanview program and the plugins.

Here are the steps I use:
1. Open the file in Irfanview and choose resize/resample
2. Set the desired new size, and be sure that "sharpen after resample" and Lanczos resample filter are chosen
3. Choose "save for web (plugin)"
4. Click on "Compress to Size" and choose 240 or less
5. Click "File - save as" and save your new file with a different name, or at a different location, from the original.

Here are some screenshots of Irfanview "in action." Hope this helps!

I am also a big fan of Irfanview for resizing. You can just use the resize/resample and preserve the Exif info, while resizing to a given file size and dimensions.
The plugin used is also available as a stand alone tool called RIOT (radical image optimizer tool)
The reason I mentioned the back focus with your 18-135 lens, is that the mark on the wall behind mickey's ear appears to be more in focus than the text on the JD bottle in that shot, where, with the prime, the text is sharp, and the mark is soft. I believe the K5 can be adjusted on a per-lens basis, so you can calibrate the lenses individually.

Thanks

VTphotog and mole I will have to look at that program and look at how to adjust for that lens and how much to adjust by.

I have the 18-135 and get quite sharp results from it, I did have to calibrate it (AF adjustment) for use on my Kr and K30. Like VTphtotg said above yours seems to be back focusing and looks like it too could use some adjustment to achieve better focus. Adjusting AF can be a challenge to get correct. Like I said above try shooting 2 identical images one using Live View and the other using the finder, if the Live View image is sharper than your AF needs adjustment. The K5 will allow AF adjustment on a per lens basis.

Yes this is my next step. Hopefully I will get to do this tomorrow.

Ok

I tried a test using the 18-135 lens at about 12" away from target as wide open as the lens would go at the different focal lengths and on a tripod. Not sure if I did this right but the lens looks ok to me. For comparison shot 1 with same setup with the DA 35 2.4 lens. I also shot one at 50mm with the filter on.

What do you think does the lens look ok? did I set the test up right?

Let me add the target was at 45 degrees of the camera, auto focused on the line in the center, both target and camera at the same height.

Thanks
Mark

On Closer look it looks as if is back focusing fro 18mm to 35mm it gets better at longer focal lengths. although maybe I should redo it at the same f stop through the range. Like F5.6 since that is as open as I can get at 135mm.

Any thoughts?

I tried re-shooting the Mickey mouse doll since I'm not sure about the lens focusing. I used a 35mm prime lens and they look soft also so I added some sharpening I then sharpened even more in PSE. Maybe picked a bad subject to photograph.
