Macro
Hi ... If the specs for ANY digital camera show macro capabilities and manual focusing, does it always mean the macro can be manually focused. I'm not sure that some may default to AF.Zene..

Well, I'd have to be wary about a question that asked if something *always* applies to *any* camera. Perhaps it might be possible to answer a question relating to two or three specific cameras in which you are interested..

Still, broadly speaking with macro it can be a good idea to focus by moving the entire camera towards or away from the subject. Even if the camera has AF it would be possible to half-press the shutter button to lock focus, and *then* move the camera as required. That's assuming you can see in the viewfinder when the subject is in focus.Regards,Peter..

Thanks Peter ... What I'm looking for are cameras that have manual macro where I do not move the camera. I will be taking several pics of one scene from very close to as deep as the scene goes using the manual focus and pick different spots. Be very hard to ask here about all the cameras I find, new and used. I thought there should be something in the specs that would address my concerns. New isn't quite as bad as I can ask the salesman, but ones I see online makes it more difficult.Zene..

I'm assuming you are referring to non-DSLRs, because with a DSLR you can always manually focus. So I'm confining what I say to non-DSLR..

Macro is quite difficult at the best of times. You may be making it more difficult..

Manually focusing on a P&S is quite difficult and not very accurate. In macro depth of field is tiny, so it's really quite hard to get focus trying to use manual. A couple of exceptions would be those cameras with manual ( or at least pseudo manual ) focus rings..

Some macro modes focus at a fixed distance, so you focus by moving the camera in those cases..

Macro modes change the lens configuration to allow more accurate close focusing..

Depends on the camera..

An example from a non-DSLR, the Olympus C5050.

Image control:Zoom outZoom 100%Zoom inExpand AllOpen in new window.

The point is here I used manual focus which is done via a magnified section on the LCD screen and pushing buttons. The intention was to focus on the letter "D" in Duracell. It seemed I did not succeed, the dust and fluff on the surface of the battery suggest I missed the intended focus point..

One thing about this camera in "super macro" mode, the zoom function is disabled, for normal photography the camera has a 3x zoom but this cannot be used here. There is still the choice of auto or manual focus, auto is good if it chooses the required point of the subject. But manual is not really much fun as the magnified image displayed is blocky and never looks sharp. Out of interest, this camera was one of the better, more advanced models of it's day, though a few years old now.Regards,Peter..

Here's an example I shot yesterday ( for kicks ) using the Canon A710..

While I was experimenting with odd ideas I did this..

This is the bulb of a small flower, the bulb is around half as wide again as the width of my index finger. It was captured with a Canon A710 hand held using the flash ( dull day ) hence the slightly odd lighting. Lots of bugs present..

I use the CHDK hack ( many thanks to those people ) and so this is a raw file processed a little in RAwTherapee ( more thanks )..

Thanks guys ... I was refereeing to non-DSLR. I guess I'd better explain what I want to do. The reason for not moving camera during macro shots is that I want to play with Helicon Focus http://www.heliconsoft.com/heliconfocus.html.

If you haven't seen it a quick download, click on RUN and it will be immediately clear what it does. My main interest will be photo shots of my model railroad and all will be macros except for some full layout shots. However, I still want to be able to do good basic rail fan and scenery shots. If there is an inexpensive way to get into DSLR macro I would be interested. Am I correct that the cheaper DSLR's will be better than the best P&S's?Zene..
