Stop the aperture down to around f/11 and you'll have a much greater depth of field (of course you'd have to adjust the shutter speed and/or ISO accordingly.) The 50mm lens is acting as a short telephoto which at close range will have a fairly narrow depth of field. By using a wider angle lens, e...

getting all over sharpness?
Short lenses to a standard lens is generally prefered. Most Pro's who shoot food use a shift lense and wider apertures to isolate the food yet keep it all in focus. Using smaller format and not having the option of a tilt shift lens put you at a disadvantage. It's back to using the right tool for...

Wide aperture short tele, tripod, diffused light, multi-shot stack as required to get the whole plate (or whatever you require) in focus. Combine in software.

getting all over sharpness?
Believe me I have. If you change focal length and move in closer then the image will have changed so you're not comparing like with like plus I've suggested a way to the OP that will make his image more acceptable (albeit not all over sharp in focus) using exactly the same set up that he used in ...

getting all over sharpness?
As JAK has so elequently stated, changing the lens from the same view point does increase the depth of field, but cropping reduces it again. Focusing on the hyperfocal distance (see same website) will maximise the use of the depth, but may not still render the front or back items acceptable until...

that's why we would like a full frame sensor from Pentax. John A "full frame" (which is a misnomer, since APS-C is a full frame also) would give LESS depth of field with all parameters being EQUIVALENT. I already said that the only solution (in camera) is to use a smaller aperture. Otherwise,...

Catch in Focus/Focus Trap
I've been using my K-r with a 50mm 'M' lens plus tube for macro recently making a fair bit of use of the catch in focus mode. I was wondering if this mode can be used to trap an insect ie. leave the camera on a tripod focused on a spot and wait for something to fly in, triggering the shutter. Ac...

Catch in Focus/Focus Trap
The image has to be out of focus to start with. MF lens. AF on camera. Then, fully depress the shutter. When the green hexagon indicates focus is achieved, the shutter will release.

Catch in Focus/Focus Trap
Thanks John. I can do that as long as I keep the button depressed. It won't fully depress until focus is achieved. What I'm after, that others seem to be able to do, is a way to fully depress the shutter button, remove my finger, then have the camera fire when focus is achieved, so that I can...

To do that you'll need a locking cable release.

Catch in Focus/Focus Trap
I got mine to work with remote control on my K5. Once CIF is turned on, change "Autofocus when using remote control" to yes. The red light flashes, press the remote and it goes out, the CIF is then enabled without holding the shutter. Just tested with some terrible self portraits.

I will add that you only seem to get 10-12 seconds for something to come into focus....maybe this can be changed?

Best place to repair my pentax K-r?
I had a Pentax digital compact that needed a clean a couple of years back. I have a couple of friends that work at their Langley (Slough) office, and asked them to see what they could do. The best price they came back with was £80, which was obviously "uneconomical", so I got a quote for a replaceme...

Lens filters for K-x
What is the size for filters (polarising etc) on my K-x? I was told that it's 49mm, but I ordered some and they don't fit. Is it 52mm I should have bought? Thanks in advance for any help. K. Well as already advised it's 52mm for the kit lenses (18-55 and 50-200.) If it's a different lens, which ...
