I checked that before I linked the photo

Indeed both are top of the class lenses, no doubt about that.
The left one is focussed a bit closer that's why it has deeper DOF.

As for the score, most know what the Pentax is

Is this law through already?

From what I understand you should be able to select it just like record, playback, set-up, custom menu will be the fourth one.
The problem most likely is that you've the camera on green mode simply set it to another mode and you can select it.

In case you didn't know, because the lens does not have an auto-aperture you can only use Av or Manual mode.

They are both good

As for everything can be fixed with the computer that's not true, of course you can fix things but that means destroying information/pixels that aren't good so you're lowering the quality of your photo.
Than something like bokeh, try making that into a good looking one

Ah yes, but you've shot the photo you're showing on F/2.8 for other reasons that has nothing to do with sharpness and I don't need to tell you which.

Don't get a TN, they have the worse colours, try looking for PVA or ISP.
For budget CRT is the best, still using mine

You need to allow use of the aperture ring, it's #37, it's on page/tab 6 of the custom menu.

The review seem to say it's a good monitor link
I don't think you should discard a model because it has one bad review

This from Wiki and it answer your question I believe

Standard-SD cards (non-SDHC) with greater than 1 GB capacity

The SD Card Association's current specifications define how a standard SD (non-SDHC) card with more than 1 GB and up to 2 GB capacity should be designed. These cards should be readable in any SD 1.01 devices that take the block length data into account. Any 1 GB or lesser card should always work (so the key question is how one's reader handles block length).

According to the specification, the maximum capacity of a standard SD card is defined by (BLOCKNR x BLOCK_LEN), where BLOCKNR may be (4096 x 512) and BLOCK_LEN may be up to 2048. This allows a capacity of 2 GB. The main problem is that some of the card readers support only a block (aka. sector) size of 512 bytes, so greater than 1 GB non-SDHC cards may cause compatibility difficulties for users of such devices.

SD and SDHC compatibility issues

The SDHC specification was completed in June 2006, but by that time, non-standard high-capacity (>1GB) SD cards (based on the older 1.x specification) were already on the market. The two types of storage cards were not interchangeable, creating some confusion among customers. SD and SDHC cards and devices have these compatibility issues :
- Devices that do not specifically support SDHC do not recognize SDHC memory cards. Some devices can support SDHC through a firmware upgrade.
- SDHC devices are backward compatible with SD memory cards.
- Some manufacturers have produced 4 GB SD cards that conform to neither the SD2.0/SDHC spec nor existing SD devices

Bought mine cheaper before the price hike, so I'm happy I did that

At least that's the basics behind it Glover, if a Tammy user concur with your findings then that's most probably the cause and not the lens or the AF sensor.
