Seems reasonable since it is on my way home. Thanks Lenny. Have you had dealings with him? The only thing is it would be a reasonable trip back to pick them up if I had to leave anything.

Seems reasonable since it is on my way home. Thanks Lenny. Have you had dealings with him? The only thing is it would be a reasonable trip back to pick them up if I had to leave anything. Yes, I've bought from him a few times - never sold to him, but give him a call and discuss what you have I th...

Focusing problem
I was out on Saturday photographing trains and I have two consecutive shots of different trains at the same location using the same focusing method: AF-S, Selective point, pre-focused on that point and waited for the train to come, then press the shutter release. The first image is not sharp anywher...

You say you "pre-focussed". But did you then turn off the AF ? Otherwise as soon as you press the shutter button when the train has arrived the camera will try and achieve focus again.

Yes, pre-focussing is a technique associated with manual focus mode usually. Of course, if you used Back Button Focus for the pre-focussing, then did not press that again, it would stay fixed, so that is the way to use it in conjunction with autofocus. Of course the shutter button has to be set t...

Focusing problem
I photograph a lot of trains and use back button AF all the time. Was SR on? I have had some instances where shots in the middle of a sequence are soft (overall soft rather than just mis-focussed) which I blame on the SR still moving the sensor

Make sure the Button Customization setting in menu 4 is set to AF2 to disable focussing with the shutter button. Otherwise all over blur is often simply camera shake. On which body? My K5 has "Enable AF/Off/Off (Live View only)" under the Shutter Button Half Press option. He says K3 so I checked o...

Focusing problem
Going back to what the OP said in the beginning, I am not convinced that once the focus has been set (either by shutter or AF button) that the camera will maintain that focus position. i.e. on my K5, I think the focus position will move. Stephen, can you confirm if you used the AF button to pre-foc...

You say you "pre-focussed". But did you then turn off the AF ? Otherwise as soon as you press the shutter button when the train has arrived the camera will try and achieve focus again. I didn't turn the AF off but once I had focused I kept the shutter release half down.

The first image of the single car unit is the second of two and both are unsharp across the frame. The second image is the first of five all of which are sharp. the focus point was just in front of the cab in both cases. These are the full size jpegs, I also shot in RAW. It isn't obvious that the ...

Focusing problem
Just had a look at the photos on Flikr and all those I saw don't look sharp at all. You need to try and identify the culprit. Is it the camera or a specific lens. Try taking the same shot of something with one lens on both the K-3 and K-5. If one camera's image is fine and the other not that woul...
