    If you look at the background some of it is in sharper focus indicating that the spider is slightly out of focus.

    There is also slight signs of a bridge camera problem if this happens to be a rather small crop from a full frame with no size reduction. In other words when the image you post is just a small crop from a much larger image. The way to judge that is to say view the final image at 2x and see if the detail is still reasonably sharp. It's down to small sensors. In this case it might be down to slight subject or camera shake.

    No sure what a shutter speed of 5 means on your camera but if it's 5 secs it's way too slow even if your main lighting was via flash. Some cameras will come up with settings like that. One way round it is to set aperture and speed manually plus flash exposure. The method varies from camera to camera. If no flash was used then ISO needs to be much much higher, probably problematically so in this case due to noise. Only way to find out is to try it.

    When people shoot macro they often focus manually and trim the focusing up by changing the lens to subject distance. If the camera has numerous AF confirm indicators this method can be used to make sure the one on the subject lights up.

    It was a serious crop and i shall see if i an get a size reduction in my software.

    It certainly was not a five second exposure so i am also unsure but will look into it.

    i have no idea (newbee) what your last paragraph means but i don't think my camera knows either.

    Hi Brian,

    The Exif data for this shot is; f8, 1/30s, ISO100, Manual Exposure, No flash.

    The 1/30s is too slow really for these mini critters and with that and the cropping no helpful. I see you were using Autofocus again, try the half press of the shutter to lock the focus and then move your body in and out and press when the critters the sharpest in the viewfinder.

    These wee spiders make great subjects.

    I right clicked - properties on here for the exif info.

    I'm probably being a bit severe suggesting a sharp 2x magnification. Safest is a big image of what ever it is and some reduction if possible..

    I think Grahame has explained the last paragraph. The limited depth of field on macro also means that some care has to be taken after the shutter is half pressed. If the camera moves the focus point will too as it's locked. So the focus can also be trimmed up via careful changes in the distance from the insect to the camera. Some cameras have a magnified view which can be useful for checking the focus but this might also make it difficult to keep the insect where you want it in the frame. Electronic views need a lot of magnification to make them really effective.
