My first bug ...
Jan 17, 2013 22:26:47 #
This little guy was kind of beat up, but I need the practice and bugs are kinda scarce ... Photo was taken with a tripod and wireless remote, and built-in flash. Didn't have my tabletop studio lights with me.
Lens: 50mm all 3 Kenko extension tubes.
Settings: f/4.00, ISO 800, Exp. 1/6
Question: How can I improve depth of field and focus?

1/6-sec is a long exposure for insect photography, f/4 provides a very narrow DoF, and ISO 800 is quite high. This is why most macro-photographers use speedlight illumination. Average speedlight exposure at ISO 400 is 1/200-sec at f/16 or f/22.
It is difficult to provide proper critique on an image that cannot be enlarged. I think the focus is fine, but am not sure. If you checked the box labeled "(store original)", then the photo is cropped too much to enlarge.

Sorry about that! Speedlite's are a completely new to me. I need to learn more about them. Any suggestions as to what I should look for and where I can do some online learning about them?
If I understand you correctly, a speedlite will improve lighting AND depth of field?

Also, a speedlight allows a shutter duration of 1/200-sec, which will reduce any lens movement, and/or insect movement (not evident).
Your focus is fine, but note how narrow your DoF at f/4.
Maybe a millimeter or so DoF on floor mat

I won't be as much help, then. I use an SB400 (Nikon). It's a small unit, but it's sufficient for macro. The feature I would look for is the ability to control the flash output in fractional amounts. My point is this: some speedlites control this function and some cameras control it. Nikon has a system known a CLS (Creative Lighting System) that allows you to adjust flash output through the camera menu. This is important to me because my SB400 has no built-in controls to do this. The shorter flash durations allow you to freeze moving subjects, resulting in sharper images..I'm using a Canon T3.

430EX II = http://www.usa.canon.com/cusa/consumer/products/cameras/speedlite_flash_lineup/speedlite_430ex_ii
580EX II = http://www.usa.canon.com/cusa/support/professional/professional_cameras/flashes/speedlite_580ex_ii
New 600EX = http://www.usa.canon.com/cusa/consumer/products/cameras/speedlite_flash_lineup/speedlite_600ex_rt
I recommend either the 430 EX II or the 580EX II. Refurbished would be my preference; then used; then new, based on cost.
