I am looking at the Pentax DAL equivalent too. Appears to be going for cheap too.

I was reading that the sweet spot or the sharpest aperture is usually two F-stops from the lowest number? I.e if Lens if F/2.8 then sharpest aperture will be F/5.6 - F/8.
Is this applicable to the 18-55mm and 50-200mm kit lens that I have with the pentax kx?
Finally, any advice on the Tamron 70-300mm lens?

The Shake reduction was on, but I didn't pay attention to the Hexagon icon.
I have noted all you said, will give it a go when next am out. I suppose I should be doing these in the Av mode right?

Ok, well firstly you're one up on a lot of newbies - you've successfully uploaded some pictures
It appears that you were intending to get the foreground in focus, and the background out of focus.
If this is so, then you've pretty much achieved it (although the fencing isn't really sharp), apparently focusing on the closer parts of the subject, and using a relatively wide aperture to ensure that the distance range over which objects appear in focus, is short. Hence you've got an out-of-focus background.
But that's just my inference from how the photos appear, and from the EXIF data embedded in the images themselves.
So, over to you. What, in detail, were you trying to achieve, how did you go about it, and to what extent do you feel your objectives were met?
Yes, I was trying to do that. Thanks.
The camera was hand held, and the weather was cloudy, perhaps this could explain why it aint sharp? Or may be I just haven't mastered the art of getting the photo sharp
With the basketball fore-court, I was hoping to having people playing in the back ground, preferably, someone making a slam dunk while I take the shot. After waiting for a while and no one turning up, I opted to take it with just the Basketball net in the background.
What will you advise in order to get sharp photos next time please?
1st - nice use of DOF, but main object - grating is not sharp, picture is not in level as well.
2nd - leaf is too dark.

The lens in question is made by Tamron. I have been offered one for 100GBP.
By the way, I have been out today to play around with the camera in the Av mode. I have a couple of shots posted, nothing fancy but to familiarise myself with the DoF.
Pictures processed in lightroom. See here.

I used auto focus, and opted for a faster shutter speed as it was windy, so trying to keep all in focus and fine tuning it manually is something I still trying to master lol.
Just to make sure I get this right, a wider aperture is a lower F number right?
